JOURNAL OF ETHNOPHARMACOLOGY 2022; 294:115332. [PMID: 35525529 DOI: 10.1016/j.jep.2022.115332] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 04/25/2022] [Accepted: 04/25/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Curcuma longa L. (Zingiberaceae) is a known blood-activating and stasis-removing traditional Chinese medicine and has relevant pharmacological properties. The rhizomes of C. longa have been used for the treatment of cardiovascular disease (CVD) in China. Previous studies have shown that sesquiterpenoids from C. longa have significant vasorelaxant effects, which are closely associated with the prevention and treatment of CVD. AIM OF THE STUDY To explore the sesquiterpenoids with vasorelaxant effects from C. longa and investigate the underlying mechanisms. MATERIALS AND METHODS The compound was isolated from C. longa by multiple chromatography technologies. Its structure was determined by extensive spectroscopic analyses, nuclear magnetic resonance (NMR) data calculations, electronic circular dichroism (ECD) data calculations, and optical rotation (OR) data calculations. The vasorelaxant effect of the isolated compound was evaluated by KCl- or phenylephrine (PHE)-inducing contraction of the rat thoracic aortic rings. Endothelial removal and L-NAME pretreatment experiments were used to verify the endothelium-dependent vasorelaxant effect of the isolated compound in rat thoracic aortic rings. NO production was monitored in human umbilical vein endothelial cells (HUVECs). Western blot was carried out in HUVECs to elucidate the potential mechanisms. RESULTS A new bisabolane-type sesquiterpenoid, curcubisabolanin A [(+)-(1S,7S,9E)-bisabola-2(3),4(15),9(10)-trien-11-ol], was isolated from the rhizomes of C. longa. curcubisabolanin A exhibited endothelium-dependent relaxation on rat thoracic aortic rings, while pre-treatment of intact aortic rings with an eNOS inhibitor (L-NAME) attenuated the vasorelaxant response of curcubisabolanin A. In addition, curcubisabolanin A induced intracellular NO production and significantly increased the levels of phosphorylated PI3K (p-PI3K), phosphorylated Akt (p-Akt), and phosphorylated eNOS (p-eNOS) in HUVECs. LY294002 (a blocker of PI3K) and MK-2206 (a highly selective inhibitor of Akt) significantly decreased these effects of curcubisabolanin A. CONCLUSIONS These findings demonstrated that the vasorelaxant effect of curcubisabolanin A was partially endothelium-dependent and was related to regulation of NO production in vascular endothelial cells through the PI3K/Akt/eNOS signaling pathway.

Using Fingerprints and Chemometrics Approaches on Gas Chromatography-Mass Spectrometry. Molecules 2022; 27:molecules27103196. [PMID: 35630672 PMCID: PMC9145967 DOI: 10.3390/molecules27103196] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 05/11/2022] [Accepted: 05/13/2022] [Indexed: 01/27/2023] Open
Abstract
The root tuber and rhizome of Curcuma longa L., abbreviated, respectively, as RCL and RHCL, are used as different medicines in China. In this work, volatile oils were extracted from RCL and RHCL. Then, gas chromatography-mass spectrometry (GC-MS) was used for RCL and RHCL volatile oils analysis, and 45 compounds were identified. The dominant constituents both in volatile oils of RCL and RHCL were turmerone, (-)-zingiberene, and β-turmerone, which covered more than 60% of the total area. The chromatographic fingerprint similarities between RCL and RHCL were not less than 0.943, indicating that their main chemical compositions were similar. However, there were also some compounds that were varied in RCL and RHCL. Based on the peak area ratio of 45 compounds, the RCL and RHCL samples were separated into principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA). Then, 20 compounds with a variable importance for the projection (VIP) value of more than 1 were the high potential contributors for RCL and RHCL differences. Furthermore, ferric ion-reducing antioxidant power (FRAP) assay results demonstrated that the volatile oils of RCL and RHCL had antioxidant activities. This study provided the material basis for the research of volatile components in RCL and RHCL and contributed to their further pharmacological research and quality control.

Abstract
Metabolic syndrome (MS) involves people with the following risk factors: obesity, hypertension, high glucose level and hyperlipidemia. It can increase the risk of heart disease, stroke and type 2 diabetes mellitus. The prevalence of MS in the world's adult population is about 20%-25%. Today, there is much care to use medicinal plants. Turmeric (Curcuma longa) as well as curcumin which is derived from the rhizome of the plant, has been shown beneficial effects on different components of MS. Thus, the purpose of this manuscript was to introduce different in vitro, in vivo and human studies regarding the effect of turmeric and its constituent on MS. Moreover, different mechanisms of action by which this plant overcomes MS have been introduced. Based on studies, turmeric and its bioactive component, curcumin, due to their anti-inflammatory and antioxidant properties, have antidiabetic effects through increasing insulin release, antihyperlipidemic effects by increasing fatty acid uptake, anti-obesity effects by decreasing lipogenesis, and antihypertensive effects by increasing nitric oxide. According to several in vivo, in vitro and human studies, it can be concluded that turmeric or curcumin has important values as a complementary therapy in MS. However, more clinical trials should be done to confirm these effects.

Abstract
:
Hypertension is a global public health concern since it can lead to complications like
stroke, heart disease, and kidney failure. These complications can add to a disability, increase
healthcare costs, and can even result in mortality. In spite of the availability of a large number of
anti-hypertensive drugs, the control of blood pressure is suboptimal in many patients. Spices have
been used as flavouring agents and in treating diseases in folk medicine since they are considered
to be rich sources of phytochemicals, especially polyphenols. Hence, during recent years, there has
been renewed interest among researchers in exploring natural sources, especially spices, in an attempt
to find cheaper alternatives with fewer side effects. Our aim is to review the relevant preclinical
and clinical studies focused on the potential use of spices in the management of hypertension.
Studies conducted on the most common spices, such as celery, cinnamon, cardamom, garlic, ginger,
saffron, and turmeric, have been elaborated in this review. These spices may lower blood pressure
via several possible mechanisms, including antioxidant effect, increase in nitric oxide production,
reduction in calcium ion concentration, modulation of the renin-angiotensin pathway, etc.

Abstract
AIM To analyze the effect of the use of carvacrol in the cardiovascular system of spontaneously hypertensive rats (SHR). METHODS Methods: Twenty animals were allocated in four groups, one group control Wistar receiving only sorbitol, used as vehicle of administration of the carvacrol (Wistar-Vehicle), one control group SHR, also receive only sorbitol (SHR-Vehicle), a third, treated with losartan (SHR-Losartan/50 mg/kg), and the fourth, treated with carvacrol (SHR - Carvacrol/20 mg/kg). Sorbitol, losartan and carvacrol were administered by oral gavage daily for 30-day. Hemodynamic variables, vascular reactivity, biochemical parameters, and expression of Mas and AT1 receptors in kidney tissues were analyzed. RESULTS SHR- Carvacrol group showed a maximal effect of inhibition of 56% in the curve of norepinephrine. The Emax of the curves with Ca2+ were smaller in the groups SHR-losartan (40.17%) and SHR-carvacrol (35.71%) when compared to the SHR-Vehicle. The carvacrol increased the expression of the MAS receptors in kidney tissue. CONCLUSION Thirty days of treatment with carvacrol showed an antihypertensive effect associated with less peripheral vascular resistance. Also, treatment with carvacrol increased the expression of MAS receptors in kidney tissue.

Abstract
1. Effects of Lepidium sativum and Curcuma longa were investigated on pharmacokinetics and pharmacodynamics of antihypertensive drug (amlodipine).2. Hypertensive rats were treated with amlodipine, Lepidium sativum, Lepidium sativum + amlodipine, Curcuma longa, and Curcuma longa + amlodipine; and their blood pressures were measured. Amlodipine in plasma samples was analysed using UPLC-TQD. Product ions of amlodipine were monitored at m/z 409.18 > 238 and 409.18 > 294; and of nitrendipine at m/z 361.16 > 315.1 and 361.16 > 329.10.3. Lepidium sativum + amlodipine treatment showed highest reduction in systolic blood pressure (SBP). Mean anti-hypertensive effect of Lepidium sativum and Curcuma longa was similar to amlodipine. Mean SBPs (1-24 h) of amlodipine, Lepidium sativum, Lepidium sativum + amlodipine, Curcuma longa, and Curcuma longa + amlodipine treated animals were found as 149.5 ± 2.4 mmHg, 151.6 ± 1.09 mmHg, and 141.8 ± 2.5 mmHg, 154.9 ± 2.2 mmHg and 144.4 ± 2.6 mmHg (p-values ≪0.05); respectively. Lepidium sativum and Curcuma longa significantly increased amlodipine Cmax by 83% (p-value 0.018) and 53% (p-value 0.035); and AUC0-t by 48% (p-value >0.05) and 56% (p-value 0.033); respectively.4. Results of pharmacokinetic and pharmacodynamic studies are in agreement. Lepidium sativum and Curcuma longa augment antihypertensive effect of amlodipine, which is also supported by pharmacokinetic observations.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) immune checkpoint is one of the most promising therapeutic targets for cancer immunotherapy, but several challenges remain in current anti-PD-1/PD-L1 therapy. Natural products, mainly derived from traditional medicine, could improve and expand anti-PD-1/PD-L1 therapy because of their advantages such as large diversity and multi-target effects. AIM OF THE STUDY This review summarize natural products, raw extracts, and traditional medicines with pharmacological effects associated with the PD-1/PD-L1 axis, particularly PD-L1. MATERIALS AND METHODS Electronic literature databases, including Web of Science, PubMed, and ScienceDirect, and online drugs and chemicals databases, including DrugBank, ZINC, PubChem, STITCH, and CTD, were searched without date limitation by February 2021. 'Natural product or herb or herbal plant or traditional medicine' and 'PD-L1' and 'Cancer immunotherapy' were used as the search keywords. Among 112 articles identified in database searching, 54 articles are full text articles, reporting in silico, in vitro, in vivo and clinical trials. 68 articles included are review articles and grey literature such as thesis and congress abstracts. RESULTS Several natural products and traditional medicines have exhibited diverse and multi-functional effects including direct blockade of PD-1/PD-L1 interactions, modulation of PD-L1 expression, and cooperation with PD-1/PD-L1 inhibitors. CONCLUSION Natural products and traditional medicines can facilitate the development of more effective and acceptable diverse strategies for anti-PD-1/PD-L1 therapy, but further exploration of natural products and pharmaceutical techniques is required.

Abstract
Hypertension is the most common non-communicable disease, with about 1.28 billion hypertensive people worldwide. It is more prevalent in men than women and more common in the elderly. Hereditary, age, obesity, lifestyle, diet, alcohol, and chronic metabolic diseases are the major risk factors of hypertension. Treating hypertension is a complex process as there are several mechanisms responsible for its pathogenesis; hence, a combination of several drugs is used for managing hypertension. Drugs used in managing hypertension are expensive and often come with associated side effects; thus, there is need for alternative means of managing this life-threatening disease. These drugs do not achieve the recommended blood pressure target in most people; more so majority of people with hypertension do not follow the treatment regimen religiously. Some Africans have been reported to become normotensive as a result of dietary consumption of spices. Several spices have been used over the years in Africa to manage hypertension. The aim of this review is to evaluate the ethnomedicinal use, bioactive phytochemical composition, bioactive compounds present, and pharmacological applications of spices commonly used in Africa for managing hypertension. Most of the plants used contained polyphenols, flavonoids, tannins, anthraquinone, flavonoids, cardiac glycosides, and saponins. Dietary supplementation of Xylopia aethiopica and other spices in diet have been proven to significantly reduced plasma angiotensin-I-converting enzyme (ACE) than simvastatin (the reference drug). Toxicological, histological, and hematological evaluation revealed that acute and chronic consumption of most of these spices are safe. Studies have also revealed that some of the spices can be used as alternative therapy alongside usual antihypertensive medications. PRACTICAL IMPLICATION: The prevalent rate of hypertension is on the increase in both the developed and developing countries. People often skip medication due to their busy schedule and anti-hypertensive potential side effects; however, this is not the case with food/spices as most people consumed them daily. Deliberate, right combinations and consistent incorporation of spices with proven anti-hypertensive potential into our diet may be of great benefit in normalizing blood pressure and mitigate other complications on the heart and vital organs.

Abstract
Protein glycation, a post-translational modification found in biological systems, is often associated with a core defect in glucose metabolism. In particular, advanced glycation endproducts are complex heterogeneous sugar-derived protein modifications implicated in the progression of pathological conditions such as atherosclerosis, diabetic complications, skin diseases, rheumatism, hypertension, and neurodegenerative diseases. Undoubtedly, there is the need to expand the knowledge about antiglycation agents that can offer a therapeutic approach in preventing and treating health issues of high social and economic importance. Although various compounds have been under consideration, little data from clinical trials are available, and there is a lack of approved and registered antiglycation agents. Next to the search for novel synthetic advanced glycation endproduct inhibitors, more and more the efforts of scientists are focusing on researching antiglycation compounds from natural origin. The main purpose of this review is to provide a thorough overview of the state of scientific knowledge in the field of natural products from plant origin (e.g., extracts and pure compounds) as inhibitors of advanced glycation endproduct formation in the period between 1990 and 2019. Moreover, the objectives of the summary also include basic chemistry of AGEs formation and classification, pathophysiological significance of AGEs, mechanisms for inhibiting AGEs formation, and examples of several synthetic anti-AGEs drugs.

Abstract
Calcium, as a second messenger, plays an important role in the pathogenesis of cardiovascular diseases (CVDs). The malfunction of calcium signaling in endothelial cells and vascular smooth muscle cells promotes hypertension. In cardiomyocytes, calcium overload induces apoptosis, leading to myocardial infarction and arrhythmias. Moreover, the calcium–calcineurin–nuclear factor of activated T cells (NFAT) pathway is essential for expressing the cardiac pro-hypertrophic gene. Heart failure is also characterized by reduced calcium transient amplitude and enhanced sarcoplasmic reticulum (SR) calcium leakage. Traditional Chinese medicine (TCM) has been used to treat CVDs for thousands of years in China. Because of its multicomponent and multitarget characteristics, TCM's unique advantages in CVD treatment are closely related to the modulation of multiple calcium handling proteins and calcium signaling pathways in different types of cells involved in distinct CVDs. Thus, we systematically review the diverse mechanisms of TCM in regulating calcium pathways to treat various types of CVDs, ranging from hypertrophic cardiomyopathy to diabetic heart disease.

Abstract
For decades, chronic diseases including cardiovascular and cerebrovascular diseases (CCVDs) have plagued the world. Meanwhile, we have noticed a close association between CCVDs and vascular lesions, such as hypertension. More focus has been placed on TMPs and natural products with vasodilation and hypotension. TMPs with vasodilatory and hypotensive activities are mainly from Compositae, Lamiaceae, and Orchidaceae (such as V. amygdalina Del., T. procuinbens L., M. glomerata Spreng., K. galanga L., etc.) whereas natural products eliciting vasorelaxant potentials were primarily from flavonoids, phenolic acids and alkaloids (such as apigenin, puerarin, curcumin, sinomenine, etc.). Furthermore, the data analysis showed that the vasodilatory function of TMPs was mainly concerned with the activation of eNOS, while the natural products were primarily correlated with the blockage of calcium channel. Thus, TMPs will be used as alternative drugs and nutritional supplements, while natural products will be considered as potential therapies for CCVDs in the future. This study provides comprehensive and valuable references for the prevention and treatment of hypertension and CCVDs and sheds light on the further studies in this regard. However, since most studies are in vitro and preclinical, there is a need for more in-depth researches and clinical trials to understand the potential of these substances.

Abstract
BACKGROUND This study was undertaken to test the hypothesis that the newly synthesized curcuminoids B2BrBC and C66 supplementation will overcome hyperoxia-induced tracheal hyperreactivity and impairment of relaxation of tracheal smooth muscle (TSM). MATERIALS AND METHODS Rat pups (P5) were exposed to hyperoxia (>95% O2 ) or normoxia for 7 days. At P12, tracheal cylinders were used to study in vitro contractile responses induced by methacholine (10-8 -10-4 M) or relaxation induced by electrical field stimulation (5-60 V) in the presence/absence of B2BrBC or C66, or to study the direct relaxant effects elicited by both analogs. RESULTS Hyperoxia significantly increased contraction and decreased relaxation of TSM compared to normoxia controls. Presence of B2BrBC or C66 normalized both contractile and relaxant responses altered by hyperoxia. Both, curcuminoids directly induced dose-dependent relaxation of preconstricted TSM. Supplementation of hyperoxic animals with B2BrBC or C66, significantly increased catalase activity. Lung TNF-α was significantly increased in hyperoxia-exposed animals. Both curcumin analogs attenuated increases in TNF-α in hyperoxic animals. CONCLUSION We show that B2BrBC and C66 provide protection against adverse contractility and relaxant effect of hyperoxia on TSM, and whole lung inflammation. Both analogs induced direct relaxation of TSM. Through restoration of catalase activity in hyperoxia, we speculate that analogs are protective against hyperoxia-induced tracheal hyperreactivity by augmenting H2 O2 catabolism. Neonatal hyperoxia induces increased tracheal contractility, attenuates tracheal relaxation, diminishes lung antioxidant capacity, and increases lung inflammation, while monocarbonyl CUR analogs were protective of these adverse effects of hyperoxia. Analogs may be promising new therapies for neonatal hyperoxic airway and lung disease.

Clin Nutr ESPEN 2020; 37:178-186. [PMID: 32359741 DOI: 10.1016/j.clnesp.2020.02.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 02/20/2020] [Accepted: 02/25/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND AND AIMS Curcuminoids and vitamin D have been shown to improve blood pressure and body weight in diabetic animals; however, consistent findings in type 2 diabetes mellitus (T2DM) patients are limited. This study was performed to evaluate the effects of curcuminoids and vitamin D, simultaneously or singly on anthropometric measurements and blood pressure in T2DM patients with insufficient vitamin D level. METHODS In this randomized, placebo-controlled clinical trial, eighty T2DM patients were randomly assigned into 4 groups receiving (1) 500 mg/day curcuminoids; (2) 50,000 IU/week vitamin D3; (3) 50,000 IU/week vitamin D3 plus 500 mg/d curcuminoids; or (4) placebos for 12 weeks. Blood pressure and anthropometric measurements were evaluated before and after intervention. RESULTS Intergroup comparisons showed that Vitamin D (main effect) significantly reduced systolic blood pressure (SBP) and diastolic blood pressure (DBP) (P = 0/000). Curcuminoids (main effect) significantly reduced DBP (P = 0/001). Interaction effects showed that curcuminoids significantly prevented the effect of vitamin D on the reduction of SBP (P = 0.006). Whereas, vitamin D and curcuminoids had a synergistic effect on DBP reduction (P = 0.006). The comparison of changes in anthropometric measurements between the four groups showed no significant differences in the raw and adjusted models. In-group comparisons showed that SBP, DBP, waist to hip circumference (WHR), body fat mass (BFM), percent body fat (PBF) and visceral fat area (VFA) values were significantly reduced in all groups except the placebo group compared to baseline values. Only in the CR-D group, there was a significant reduction in body weight (P = 0/047). CONCLUSIONS Curcuminoids and vitamin D may have beneficial effects on blood pressure and anthropometric measurements in T2DM patients. CLINICAL REGISTRATION: http://www.IRCT.ir:IRCT2017041213678N22.

Abstract
Hypertension (HTN) is a worldwide epidemic in both developed and developing countries. It is one of the leading causes of major health problems such as cardiovascular disease, stroke, and heart attack. In recent years, several studies have reported associations between specific dietary ingredients and improving HTN. Nutraceuticals are natural food components with pharmacological properties. Reports suggest that functional foods and nutraceutical ingredients might support patients to obtain the desired therapeutic blood pressure (BP) goals and reduce cardiovascular risks by modulating various risk factors such as oxidative stress, renin-angiotensin system hyperactivity, inflammation, hyperlipidemia, and vascular resistance. We review the recent clinical experiments that have evaluated the biological and pharmacological activities of several types of nutraceuticals, including sour tea, cocoa, common spices, vitamin C, vitamin E, lycopene, flavonoids, coenzyme Q10, milk's tripeptides, calcium, magnesium, polyunsaturated fatty acids, and prebiotics in preventing and treating HTN. This review summarizes recent knowledge about the impact of common nutraceuticals for the regulation of BP.

Abstract
Untreated hypertension is a major cause for a wide array of diseases affecting cardiovascular system. Oxidative stress has been implicated in the development of hypertension. The impairment between the balance of antioxidants and pro-oxidants contributes to the elevation of blood pressure. Over generation of free radicals produces a decreased bioavailability of nitric oxide. Eventually, this will cause a rise in total peripheral resistance and lead to endothelial dysfunction. Noticeable symptoms are usually experienced when hypertension enters the advanced stage with lifelong health complications. Hypertensive patients are required to take medications for indefinite period of time to prevent further deterioration. Many of these therapeutic agents are costly and associated with unwanted side effects. Curcuma longa (CL) or turmeric is one of the alternative herbs which confers medicinal properties. This review aims to summarise the effects of CL and its active constituents on blood pressure derived from preclinical and clinical published articles. Studies documented that CL and its active constituents could reduce blood pressure. These were achieved by antioxidant, anti-inflammatory activity, calcium (II) ion concentration interference, β2-adrenergic receptor activation, and renin-angiotensin system inhibition. There is a prospect for CL in the management of hypertension. However, limited researches of CL have been conducted on human. Thus, more well-planned studies should be carried out to ascertain its effectiveness.

Abstract
Objective To clarify the underlying mechanism of turmeric, which is traditionally used as a medicinal plant for the treatment of cardiovascular disorders, such as hypertension, and palpitations. Methods Methanol extracts of different turmeric were used. A tissue-organ-bath system was used to investigate the vasoactive effects of methanol extracts from 5 kinds of turmeric on isolated porcine basilar arteries. The arterial rings were suspended in physiological solution that was maintained at 37 °C temperature with a continuous supply of 95% O2 and 5% CO2. Results All turmeric extracts (20–800 μg/mL) induced concentration-dependent relaxation of the isolated porcine basilar artery pre-contracted with U46619 (1-5 × 10−9 M) in arterial rings with or without endothelium. There were no significant differences in the relaxation induced by different turmeric or between the endothelium-intact and denuded arteries. In depolarized, Ca2+-free medium, the turmeric extracts inhibited CaCl2-induced contractions and caused a concentration-dependent rightward shift of the response curves. In addition, propranolol (a non-specific β-adrenoceptor antagonist) slightly inhibited the relaxation induced by turmeric. In contrast, Nω-nitro-l-arginine, indomethacin, tetraethylammonium, glibenclamide and 4-aminopyridine did not affect turmeric-induced relaxation. Conclusion These results demonstrated that turmeric induced endothelium-independent relaxation of the porcine basilar artery, which may be due to the inhibition of extracellular and intracellular Ca2+ receptors and the partial inhibition of β-adrenergic receptors in vascular smooth muscle cells.

Abstract
BACKGROUND Curcumin (Cur) is a natural lipophilic polyphenol compound extracted from the rhizome of turmeric. Recently, protective effect of Cur on cardiovascular system is paid close attention. Some researches demonstrated that Cur could induce vascular relaxation in many arterial beds. However, relaxant effect of Cur on rat superior mesenteric artery is not clear. This present study will investigate the vasorelaxant effect of Cur on rat superior mesenteric arteries and the mechanisms involved. METHODS The isometric tension of rat superior mesenteric arterial rings was recorded by a sensitive myograph system in vitro. The vasodilation of Cur at various concentrations (range: 10-8-10-4 M) on potassium chloride (KCl; 60 mmol/L)-precontracted or phenylephrine hydrochloride (PE; 10 μmol/L)-precontracted arterial rings were observed. We also observed vasorelaxant effect of Cur on KCl (60 mM)-preconstricted rat superior mesenteric arterial rings after incubating the inhibitors of endothelial mechanism, including the endothelial nitric oxide synthase inhibitor Nω-nitro-L-arginine methyl ester, the guanylate cyclase inhibitor 1H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one, and the cyclooxygenase inhibitor indomethacin, and inhibitors of potassium ion channel, including 4-aminopyridine (Voltage-sensitive K+ channel blockers), and tetraethylammonium chloride (Ca2+ activated K+ channel blockers), and BaCl2 (Inward rectifying K+ channel blockers), and glibenclamide (ATP -sensitive K+ channel blockers), respectively. The effects of Cur are expressed as percentage of relaxation from the precontraction induced by KCl (60 mmol/L) or PE (10 μmol/L). The Emax value refers to the maximum relaxation. The pD2 value refers to the negative logarithmic value of the drug concentration that produces 50% Emax. RESULTS Cur concentration dependently relaxed the superior mesenteric artery rings with endothelium precontracted by PE (Emax = 84.33 ± 1.11 and pD2 = 5.03 ± 0.02) or KCl (Emax = 80.96 ± 2.12% and pD2 = 4.32 ± 0.01). The vasorelaxant effect of Cur on the superior mesenteric artery rings relied on endothelium partially. Indomethacin (5 μM) significantly inhibited the effect. However, 1H-[1,2,4]Oxadiazolo[4,3-a]quinoxalin-1-one (10 μM) and Nω-nitro-L-arginine methyl ester (100 μM) had no effect on the action. In artery rings without endothelium, vasorelaxation induced by Cur was attenuated by 4-aminopyridine (100 μM). However, barium chloride dehydrate (10 μM), glibenclamide (10 μM), and traethylammonium chloride (1 mM) did not affect vasorelaxation induced by Cur. Moreover, Cur also significantly inhibited contraction induced by increasing external calcium in Ca2+-free medium plus K+ (60 mM) and releasing intracellular Ca2+ in the Ca2+-free solution. CONCLUSIONS Our results suggested that Cur induces relaxation in superior mesenteric arterial rings through an endothelium-dependent pathway, involving prostanoid, and also through an endothelium-independent pathway, opening K+ channel, and blockade of Ca2+ influx and intracellular Ca2+ release.

Abstract
Curcuma, a valuable genus in the family Zingiberaceae, includes approximately 110 species. These plants are native to Southeast Asia and are extensively cultivated in India, China, Sri Lanka, Indonesia, Peru, Australia, and the West Indies. The plants have long been used in folk medicine to treat stomach ailments, stimulate digestion, and protect the digestive organs, including the intestines, stomach, and liver. In recent years, substantial progress has been achieved in investigations regarding the chemical and pharmacological properties, as well as in clinical trials of certain Curcuma species. This review comprehensively summarizes the current knowledge on the chemistry and briefly discusses the biological activities of Curcuma species. A total of 720 compounds, including 102 diphenylalkanoids, 19 phenylpropene derivatives, 529 terpenoids, 15 flavonoids, 7 steroids, 3 alkaloids, and 44 compounds of other types isolated or identified from 32 species, have been phytochemically investigated. The biological activities of plant extracts and pure compounds are classified into 15 groups in detail, with emphasis on anti-inflammatory and antitumor activities.

Abstract
BACKGROUND Artemisia campestris L. (Asteraceae) is a medicinal herb traditionally used to treat hypertension and many other diseases. Hence, this study is aimed to analyze the essential oil of A. campestris L (AcEO) and to investigate the antiplatelet, antioxidant effects and the mechanisms of its vasorelaxant effect. METHODS The chemical composition of AcEO was elucidated using GC/MS analysis. Then, the antioxidant effect was tested on DPPH radical scavenging and on the prevention of β-carotene bleaching. The antiplatelet effect was performed on the presence of the platelet agonists: thrombin and ADP. The mechanism of action of the vasorelaxant effect was studied by using the cellular blockers specified to explore the involvement of NO/GC pathway and in the presence of calcium channels blockers and potassium channels blockers. RESULTS AcEO is predominated by the volatiles: spathulenol, ß-eudesmol and p-cymene. The maximal antioxidant effect was obtained with the dose 2 mg/ml of AcEO. The dose 1 mg/ml of AcEO showed a maximum antiplatelet effect of, respectively 49.73% ±9.54 and 48.20% ±8.49 on thrombin and ADP. The vasorelaxation seems not to be mediated via NOS/GC pathway neither via the potassium channels. However, pretreatment with calcium channels blockers attenuated this effect, suggesting that the vasorelaxation is mediated via inhibition of L-type Ca2+ channels and the activation of SERCA pumps of reticulum plasma. CONCLUSION This study confirms the antioxidant, antiplatelet and vasorelaxant effects of A.campestris L essential oil. However, the antihypertensive use of this oil should be further confirmed by the chemical fractionation and subsequent bio-guided assays.

Chemical composition, vasorelaxant, antioxidant and antiplatelet effects of essential oil of Artemisia campestris L. from Oriental Morocco. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 17:82. [PMID: 28143473 PMCID: PMC5282690 DOI: 10.1186/s12906-017-1598-2] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2016] [Accepted: 01/21/2017] [Indexed: 12/18/2022]
Abstract
BACKGROUND Artemisia campestris L. (Asteraceae) is a medicinal herb traditionally used to treat hypertension and many other diseases. Hence, this study is aimed to analyze the essential oil of A. campestris L (AcEO) and to investigate the antiplatelet, antioxidant effects and the mechanisms of its vasorelaxant effect. METHODS The chemical composition of AcEO was elucidated using GC/MS analysis. Then, the antioxidant effect was tested on DPPH radical scavenging and on the prevention of β-carotene bleaching. The antiplatelet effect was performed on the presence of the platelet agonists: thrombin and ADP. The mechanism of action of the vasorelaxant effect was studied by using the cellular blockers specified to explore the involvement of NO/GC pathway and in the presence of calcium channels blockers and potassium channels blockers. RESULTS AcEO is predominated by the volatiles: spathulenol, ß-eudesmol and p-cymene. The maximal antioxidant effect was obtained with the dose 2 mg/ml of AcEO. The dose 1 mg/ml of AcEO showed a maximum antiplatelet effect of, respectively 49.73% ±9.54 and 48.20% ±8.49 on thrombin and ADP. The vasorelaxation seems not to be mediated via NOS/GC pathway neither via the potassium channels. However, pretreatment with calcium channels blockers attenuated this effect, suggesting that the vasorelaxation is mediated via inhibition of L-type Ca2+ channels and the activation of SERCA pumps of reticulum plasma. CONCLUSION This study confirms the antioxidant, antiplatelet and vasorelaxant effects of A.campestris L essential oil. However, the antihypertensive use of this oil should be further confirmed by the chemical fractionation and subsequent bio-guided assays.

Abstract
Hypertension is a major risk factor for coronary heart disease, kidney disease, and stroke. Interest in medicinal or nutraceutical plant bioactives to reduce hypertension has increased dramatically. The main biological regulation of mammalian blood pressure is via the renin-angiotensin-aldosterone system. The key enzyme is angiotensin converting enzyme (ACE) that converts angiotensin I into the powerful vasoconstrictor, angiotensin II. Angiotensin II binds to its receptors (AT1) on smooth muscle cells of the arteriole vasculature causing vasoconstriction and elevation of blood pressure. This review focuses on the in vitro and in vivo reports of plant-derived extracts that inhibit ACE activity, block angiotensin II receptor binding and demonstrate hypotensive activity in animal or human studies. We describe 74 families of plants that exhibited significant ACE inhibitory activity and 16 plant families with potential AT1 receptor blocking activity, according to in vitro studies. From 43 plant families including some of those with in vitro bioactivity, the extracts from 73 plant species lowered blood pressure in various normotensive or hypertensive in vivo models by the oral route. Of these, 19 species from 15 families lowered human BP when administered orally. Some of the active plant extracts, isolated bioactives and BP-lowering mechanisms are discussed.

Abstract
A human study of the effects on hemodynamics of caffeine and epigallocatechin-3-O-gallate (EGCG) was performed. Caffeine tablets (200 mg) were orally administered to healthy males aged between 25 and 35 years 30 min after oral administration of EGCG tablets (100 and 200 mg). The increase in BP induced by caffeine was inhibited when co-administrated with EGCG. We found that caffeine slightly decreased heart rate (HR) in the volunteers. Although EGCG enhanced HR reduction, the effect was not significant. In addition, caffeine increased blood catecholamine levels, but EGCG inhibited the increase in noradrenaline, adrenaline and dopamine levels induced by caffeine. Whether EGCG decreases the elevated HR and systolic perfusion pressure, and ventricular contractility induced by adrenergic agonists in the isolated rat heart was investigated. The modified Krebs-Henseleit solution was perfused through a Langendorff apparatus to the isolated hearts of rats. HR, systolic perfusion pressure, and developed maximal rates of contraction (+dP/dtmax) and relaxation (-dP/dtmax) were increased by epinephrine (EP) and isoproterenol (IP). In contrast, EGCG decreased the elevated HR, systolic perfusion pressure, and left ventricular ±dp/dtmax induced by EP and/or IP. In conclusion, EGCG could attenuate the hemodynamics stimulated by caffeine through decreasing catecholamine release.

Abstract
BACKGROUND/AIM There is no information on the dose-response relationship of curcumin on the hemodynamic variables of the heart at the organ level in isolated perfused rat hearts. We aimed to investigate the effects and mechanisms of curcumin on the hemodynamic variables of isolated perfused rat hearts. MATERIALS AND METHODS Rats were randomly divided into 9 groups. The isolated rat heart was retrogradely perfused with modified Krebs-Henseleit solution. After the stabilization period, each group was administered one of the following treatments for 25 min: saline, dimethyl sulfoxide, and curcumin (0.2 µM, 1 µM, and 5 µM); atropine (1 µM); atropine (1 µM) + curcumin (1 µM); L-NAME (100 µM); or L-NAME (100 µM) + curcumin (1 µM). Hemodynamic variables of the heart were measured. RESULTS Curcumin at dose of 1 µM decreased the heart rate (from 271 ± 11.1 to 200.4 ± 14.3 beats/min, P = 0.011) but increased end-diastolic pressure (from 7.0 ± 0.4 to 54.6 ± 7.9 mmHg, P = 0.0008). A dose of 5 µM curcumin caused a decrease in the developed pressure (from 87.58 ± 9.0 to 65.40 ± 7.0 mmHg, P = 0.047) but an increase in the end-diastolic pressure (from 6.8 ± 0.6 to 48.9 ± 7.7 mmHg, P = 0.005). Atropine (1 µM) reversed the effects of curcumin on the heart. CONCLUSION Our results suggest that curcumin produces dose-dependent negative chronotropic and inotropic effects in isolated perfused rat hearts.

Abstract
Turmeric is harvested with high moisture content and should be dried before the storage. It is observed that drying is quickest when the rhizomes are peeled and cut in small cylindrical pieces. In order to describe the process, normally a diffusive model is used, considering boundary condition of the first kind for the diffusion equation. This article uses analytical solutions considering boundaries conditions of the first (model 1) and third (model 2) kinds coupled to an optimizer to describe the drying process. It is shown that, for model 1, the fit of the analytical solution to the experimental data is biased, despite the good statistical indicators (chi-square χ(2) equal to 1.7095 × 10(-3) and coefficient of correlation R(2) of 0.9988). For model 2, the errors of the experimental points about the simulated curve can be considered randomly distributed, and the statistical indicators are much better than those obtained for model 1: χ(2) = 3.5596 × 10(-4) and R(2) = 0.9996.

Hypotensive and vasorelaxant effects induced by the ethanolic extract of the Mimosa caesalpiniifolia Benth. (Mimosaceae) inflorescences in normotensive rats. JOURNAL OF ETHNOPHARMACOLOGY 2015; 164:120-128. [PMID: 25683301 DOI: 10.1016/j.jep.2015.02.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Revised: 01/29/2015] [Accepted: 02/04/2015] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caatinga is highly influenced by its seasonality. This species is endemic in the northeastern region, which is rich in plants with pharmacological potential. Many of these plants are used by the population and some of them have confirmed pharmacological properties. Mimosa caesalpiniifolia Benth. (Mimosaceae) is a native plant from northeastern Brazil׳s caatinga, popularly known as sabiá and cascudo. The tea from the inflorescence of this species is used by the population of the semi-arid for the treatment of hypertension, and the utilization of the plant bark for the staunching of bleedings and wound washing in order to prevent inflammation; also, the ingestion of the bark infusion is used in the treatment of bronchitis. However, its pharmacological effects and mechanisms of action have not yet been studied. The aim of the present study was to determine the effect of the ethanolic extract of M. caesalpiniifolia on the cardiovascular system in rats. MATERIAL AND METHODS In a study for the assessment of the hypotensive effect of the extract, the polyethylene catheters were inserted in the aorta artery and inferior vena cava for the measurement of the arterial pressure and heart rate. When intragastric administration was performed, only one catheter was implanted in the abdominal aorta. In studies for the vasorelaxant activity, mesenteric arterial rings (1-2mm) were used: they were kept in Tyrode׳s solution (95% O2 and 5% CO2) and submitted to tension of 0.75 g/f for 1h. The results were expressed as mean ± S.E.M., significant to the values of p<0.05. RESULTS The administration of the doses through venous pathway (6.25; 12.5 and 25mg/kg, i.v.) promoted hypotension followed by bradycardia in the higher doses. The pre-treatment with atropine (2mg/kg, i.v.) interrupted both the hypotension and the bradycardia; with hexamethonium, hypotension was reverted and bradycardia was attenuated. While the administration of tea/flowers (25mg/kg i.v.) also promoted a following section of hypotension, a slight increase in heart rate was observed. When administered orally, MC-EtOH/flowers (100mg/kg, v.o.) promoted a decrease in the arterial pressure from 90 min on, without a significant alteration in the heart rate in relation to the control. In the in vitro study, a pharmacological trial was performed with the extracts obtained from parts of the species M. caesalpiifolia (leaves, bark, fruit and inflorescences). Among all extracts tested, the ethanolic extract from the inflorescences (MC-EtOH/flowers) presented higher vasorelaxant potency in relation to the other parts of the plant. Henceforth, MC-EtOH/flowers was used in the sequence. In mesenteric preparations pre-contracted with phenylephrine (10(-5)M), the MC-EtOH/flowers (0.1-750 µg/ml) promoted vasorelaxant effect regardless of the vascular endothelium. MC-EtOH/flowers inhibited the contractions induced by the cumulative addition of phenylephrine (10(-9)-10(-5)mol/l) or CaCl2 (10(-6)-3 × 10(-2)M), in a concentration-dependent way. In contractions induced by S(-)Bay K 8644, a Cav-L activator, the MC-EtOH/flowers promoted concentration-dependent relaxation, corroborating previous results. CONCLUSION The tea of flowers of M. caesalpiniifolia promotes hypotension and tachycardia, whereas ethanolic extract (MC-EtOH) promotes hypotension and bradycardia involving the participation of the muscarinic and ganglionic pathways, as well as vasorelaxant action involving the Ca(2+) influx inhibition blockade.

Antihypertensive Effect of Syzygium cumini in Spontaneously Hypertensive Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:605452.

Abstract
This study evaluated the in vivo potential antihypertensive effect of hydroalcoholic extract of Syzygium cumini leaves (HESC) in normotensive Wistar rats and in spontaneously hypertensive rats (SHR), as well as its in vitro effect on the vascular reactivity of resistance arteries. The hypotensive effect caused by intravenous infusion of HESC (0.01-4.0 mg/kg) in anesthetized Wistar rats was dose-dependent and was partially inhibited by pretreatment with atropine sulfate. SHR received HESC (0.5 g/kg/day), orally, for 8 weeks and mean arterial pressure, heart rate, and vascular reactivity were evaluated. Daily oral administration of HESC resulted in a time-dependent blood pressure reduction in SHR, with a maximum reduction of 62%. In the endothelium-deprived superior mesenteric arteries rings the treatment with HESC reduced by 40% the maximum effect (E max) of contraction induced by NE. The contractile response to calcium and NE of endothelium-deprived mesenteric rings isolated from untreated SHR was reduced in a concentration-dependent manner by HESC (0.1, 0.25, and 0.5 mg/mL). This study demonstrated that Syzygium cumini reduces the blood pressure and heart rate of SHR and that this antihypertensive effect is probably due to the inhibition of arterial tone and extracellular calcium influx.

Abstract
This study focused on the synthesis and characterization of a natural polymeric system employing the interpenetrating polymer network (IPN) comprising curcumin as a bioactive. Biopolymers and actives such as chitosan, hypromellose, citric acid, genipin, and curcumin were used to develop an effective, biodegradable, and biocompatible film employed therapeutically as a wound healing platform. The semi-IPN films were investigated for their physicochemical, physicomechanical, and biological properties by quantification by FTIR, DSC, and Young's modulus. Following characterization, an optimum candidate formulation was produced whereby further in vitro and ex vivo studies were performed. Results revealed a burst release occurring at the first hour with 1.1 mg bioactive released when in contact with the dissolution medium and 2.23 mg due to bioactive permeation through the skin, thus suggesting that the lipophilic nature of skin greatly impacted the bioactive release rate. Furthermore, chemical and mechanical characterization and tensile strength analysis revealed that the degree of crosslinking and concentration of polymeric material used significantly influenced the properties of the film.

Abstract
Abstract
Objectives
Phosphodiesterase (PDE)-5 inhibitors are useful as vasodilators for the treatment of pulmonary arterial hypertension. We aimed to study curcumin analogues for PDE5 inhibitory activity and vasorelaxation of rat pulmonary arteries.
Methods
Three natural curcuminoids (1–3) and six synthetic analogues (4–9) were tested for PDE5 and PDE6 inhibitory activities using enzymatic radioassay. Their vasorelaxation was measured using freshly isolated segments of rat pulmonary artery and aorta.
Key findings
Curcuminoids (1–3) mildly inhibited PDE5 (half maximal inhibitory concentration (IC50) = 18 µm): the metamethoxyl of curcumin was important for PDE5 inhibition. But hydroxyl rearrangements, removing both methoxyls and one ketomethylene, yielded the potent 7 and 9 (IC50 = 4 µm) (compared with sildenafil, IC50 = 0.03 µm). Only 1, 3 and 4 were PDE5 selective over PDE6. Triazole-carboxylic addition provided water-solubility while preserving potency. All analogues possessed concentration-dependent vasorelaxant activity on pulmonary arteries (40% of maximal effective concentration (EC40) = 29–90 µm, maximum response = 60–90% at 300 µm), while compounds (1–8) were weakly acting in aorta (maximum response <40%). Only demethoxycurcumin (2) and analogues 5, 8, 9 had endothelium-dependent actions. Sildenafil was highly potent (EC40 = 0.04 µm) and highly endothelium dependent in pulmonary artery but weak on intact aorta (EC40 = 1.8 µm). Activity profiles suggest actions through additional cell pathways for promoting vasorelaxation.
Conclusions
Curcumin analogues are potential leads for developing efficacious and selective PDE5 inhibitors and other pathologies of pulmonary hypertension.

Hypotensive and vasorelaxant effects of sericin-derived oligopeptides in rats. ISRN PHARMACOLOGY 2013; 2013:717529. [PMID: 24312733 PMCID: PMC3839117 DOI: 10.1155/2013/717529] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2013] [Accepted: 09/22/2013] [Indexed: 11/29/2022]
Abstract
Sericin-derived oligopeptides obtained from silk cocoons were investigated for the in vivo hypotensive effect and investigated for the underlying mechanism involved in vasodilation in isolated rat thoracic aorta. In normotensive anesthetized rats, oligopeptides induced an immediate and transient hypotensive activity. In rat aortic rings, oligopeptides induced a concentration-dependent vasorelaxation in vessels precontracted with both KCl and phenylephrine (PE) with endothelium-intact or endothelium-denuded rings. In endothelium-intact rings, pretreatment with Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME, 100 µM), an inhibitor of the NO synthase (NOS) or 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (ODQ, 1 µM), a selective inhibitor of the guanylyl cyclase enzyme, significantly reduced the relaxant effect of oligopeptides. However, indomethacin, an inhibitor of the cyclooxygenase, had no effect on oligopeptides-induced relaxation. In addition, pretreatment with tetraethylammonium (TEA, 5 mM) reduced the maximal relaxant effect induced by oligopeptides. By contrast, relaxation was not affected by 4-aminopyridine (4-AP, 1 mM), glibenclamide (10 µM), or barium chloride (BaCl2, 1 mM). In depolarization Ca2+-free solution, oligopeptides inhibited calcium chloride- (CaCl2-) induced contraction in endothelium-denuded rings in a concentration-dependent manner. Nevertheless, oligopeptides attenuated transient contractions in Ca2+-free medium containing EGTA (1 mM) induced by 1 µM PE, but they were not affected by 20 mM caffeine. It is obvious that potent vasodilation effect of oligopeptides is mediated through both the endothelium and the vascular smooth muscle.

Abstract
BACKGROUND Kolaviron (KV) (biflavonoid from Garcinia kola) and extract of Curcuma longa (CL) are frequently used in folk medicine for treatment of hypertension. One of their mechanisms of action is to enhance antioxidant properties in animals. N(G)- nitro- l- arginine methyl- ester (L- NAME) is L- arginine analogue, which by binding to Nitric Oxide Synthase (NOS) may induce hypertension partly due to increase in tissues oxidative stress. OBJECTIVES To investigate the effect of L- NAME on some biochemical indices and the possible protective effect of KV or CL. MATERIALS AND METHODS Four groups consisting of 6 rats each were used. One group served as control, second group received L- NAME (40 mg/kg/day). Third and fourth groups were treated with KV and CL, respectively and also received L- NAME. KV and CL were given at a dose of 200 mg/kg/day. RESULTS L- NAME caused a significant (P <0.05) increase in the levels of serum urea, creatine kinase and alanine aminotransferase relative to controls. L- NAME treated rats had markedly decreased hepatic catalase (CAT), superoxide dismutase (SOD), glutathione- S- transferase (GST) and reduced glutathione (GSH) levels. Precisely, L- NAME decreased CAT, SOD, GST and GSH by 48, 52, 76 and 40%, respectively. L- NAME intoxication significantly decreased (P <0.05) renal GSH and SOD levels. Also, L- NAME caused a significant (P <0.05) induction of lipid peroxidation (LPO) in the animals. Administration of KV or CL with L- NAME caused significant (P <0.05) inhibition of LPO and augments tissue antioxidant indices. CONCLUSION These results confirm the adverse effect of L- NAME on biochemical indices and, the ability of kolaviron or Curcuma longa to ameliorate the alterations.

Abstract
Medicinal plants are traditionally used in folk medicine as natural healing remedies with therapeutic effects such as prevention of cardiovascular diseases, inflammation disorders, or reducing the risk of cancer. In addition, pharmacological industry utilizes medicinal plants due to the presence of active chemical substances as agents for drug synthesis. They are valuable also for food and cosmetic industry as additives, due to their preservative effects because of the presence of antioxidants and antimicrobial constituents. To commonly used medicinal plants with antioxidant activity known worldwide belong plants from several families, especially Lamiaceae (rosemary, sage, oregano, marjoram, basil, thyme, mints, balm), Apiaceae (cumin, fennel, caraway), and Zingiberaceae (turmeric, ginger). The antioxidant properties of medicinal plants depend on the plant, its variety, environmental conditions, climatic and seasonal variations, geographical regions of growth, degree of ripeness, growing practices, and many other factors such as postharvest treatment and processing. In addition, composition and concentration of present antioxidants, such as phenolic compounds, are related to antioxidant effect. For appropriate determination of antioxidant capacity, the extraction technique, its conditions, solvent used, and particular assay methodology are important.

Abstract
The monoterpene (-)-borneol is present in essential oils of several medicinal plants. The aim of this study was to evaluate (-)-borneol effects on rat thoracic aorta artery rings. The cumulative addition of (-)-borneol (10(-9) -3 × 10(-4) M) on a phenylephrine-induced pre-contraction (10(-6) M) promoted a vasorelaxant effect in a concentration-dependent manner and independent of vascular endothelium. A similar effect was obtained on KCl-induced pre-contractions (80 mM). (-)-Borneol (10(-5) -3 × 10(-4 ) M) inhibited contractions induced by cumulative addition of CaCl2 (10(-6) -3 × 10(-2) M) in depolarizing medium without Ca(2+) in a concentration-dependent manner. On S-(-) Bay K 8644-induced pre-contractions (10(-7) M), (-)-borneol did not induce significant changes compared with KCl-induced pre-contractions. In a Ca(2+) -free medium, (-)-borneol (10(-5) , 10(-4) or 10(-3) M) interfered in calcium mobilization from phenylephrine (10(-6) M)- or caffeine (20 mM)-sensitive intracellular stores. The involvement of K(+) channels was evaluated by tetraethylammonium (3 mM), 4-aminopyridine (1 mM) and glibenclamide (10(-5) M) pre-treatment, and (-)-borneol-induced vasorelaxation was markedly attenuated. Thus, this vasorelaxant effect can probably be attributed to calcium influx blockade through voltage-operated calcium channels (CaV L), calcium mobilization from intracellular stores and potassium channels activation.

Abstract
Citronellol is an essential oil constituent from the medicinal plants Cymbopogon citratus, Cymbopogon winterianus and Lippia alba which are thought to possess antihypertensive properties. Citronellol-induced cardiovascular effects were evaluated in this study. In rats, citronellol (1-20 mg/kg, i.v.) induced hypotension, which was not affected by pre-treatment with atropine, hexamethonium, N(omega)-nitro-L-arginine methyl ester hydrochloride or indomethacin, and tachycardia, which was only attenuated by pre-treatment with atropine and hexamethonium. These responses were less than those obtained for nifedipine, a reference drug. In intact rings of rat mesenteric artery pre-contracted with 10 microM phenylephrine, citronellol induced relaxations (pD(2) = 0.71 +/- 0.11; E(max) = 102 +/- 5%; n = 6) that were not affected by endothelium removal, after tetraethylamonium in rings without endothelium pre-contracted with KCl 80 mM. Citronellol strongly antagonized (maximal inhibition = 97 +/- 4%; n = 6) the contractions induced by CaCl(2) (10(-6) to 3 x 10(-3 )M) and did not induce additional effects on the maximal response of nifedipine (10 microM). Finally, citronellol inhibited the contractions induced by 10 microM phenylephrine or 20 mM caffeine. The present results suggest that citronellol lowers blood pressure by a direct effect on the vascular smooth muscle leading to vasodilation.

Abstract
Curcumin is a polyphenol responsible for the yellow color of turmeric, a curry spice. A large body of evidence showed that curcumin possessed a variety of beneficial activities. We report a case of transient complete atrioventricular block in a 38-year-old man, after intake of curcumin containing pills for on 1 month. Since all other possible causes of conduction disturbance were excluded and causal relation was achieved by re-intake of the same amount of turmeric containing pills, side-effect of the curcumin containing pills was identified as the most likely diagnosis. After cessation of the pills, no further conduction disturbances and associated symptoms were noticed for the ensuing 6 months since discharge.
