Abstract
The preservation of the genetic resources of crop wild relatives (CWRs) is crucial for food production systems and is considered a vital measure for global agricultural health and food security. The identification of potential areas where CWRs can thrive is one of the first steps towards their conservation. In this study, we used a maximum entropy model (MaxEnt) to determine the habitat suitability of seven wild relatives of pears (Pyrus L.) for the first time. We aimed to identify high-priority areas for conservation and determine the hotspots for rich biodiversity in Iran. The study showed excellent predictive performance for all species studied (AUC value ≥ 90). The soil depth, solar radiation, minimum temperature of the coldest month (Bio6), and precipitation of the wettest quarter (Bio16) were the main environmental factors that influenced the habitat suitability of all seven species, according to permutation importance. The projected maps revealed that P. elaeagnifolia had the largest suitable habitat area, while P. glabra had the lowest. The results also showed that less than 5% of the suitable habitats for these seven species were in protected areas. This research highlights the need for national preservation policies and the development of cultivation and rehabilitation strategies for these threatened species.

[PMID: 37315649 DOI: 10.1016/j.jep.2023.116696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 05/19/2023] [Accepted: 05/28/2023] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rosa webbiana (Family: Rosaceae) is used by South Asian herbalists to treat gastrointestinal and respiratory disorders. AIM OF THE STUDY This research aimed at multiple targets to verify R. webbiana for treating diarrhea and asthma. In vitro, in vivo, and in silico experiments were planned to demonstrate the antispasmodic and bronchodilator potential of R. webbiana. MATERIALS AND METHODS The bioactive compounds of R. webbiana were identified and quantified through LC ESI-MS/MS and HPLC. These compounds were predicted for muti-mechanisms of bronchodilator and antispasmodic potential in network pharmacology and molecular docking. In vitro methods (isolated rabbit trachea, bladder, and jejunum tissues) confirmed these multi-mechanisms for antispasmodic and bronchodilator effects. Antiperistalsis, antidiarrheal, and antisecretory experiments were conducted in in-vivo experiments. RESULTS The phytochemical analysis indicates the presence of rutin (742.91 μg/g), kaempferol (726.32 μg/g), and quercitrin (688.20 μg/g) in Rw. EtOH. These bioactive compounds in network pharmacology interfere with the pathogenic genes of diarrhea and asthma, which are the members of calcium-mediated signaling pathways and showed the stronger binding affinity towards voltage-gated L-type calcium channels, myosin light chain-kinase, Calcium calmodulin-dependent-kinase, Phosphodiesterase-4, and phosphoinositide phospholipase-C in molecular docking. Rw. EtOH elicited a spasmolytic response in isolated jejunum, trachea, and urine preparations by relaxing K+ (80 mM) and CCh (1 μM) spastic contractions. Additionally, it suppressed calcium concentration-response curves to the right, like verapamil. Like dicyclomine, it caused a rightward parallel shift of the CCh curves, followed by a non-parallel shift at higher concentrations with suppression of the maximal response. Like papaverine, it also caused isoprenaline-induced inhibitory CRCs to shift to the left. Verapamil did not potentiate isoprenaline-induced inhibitory CRCs, although it was more efficacious against K+ (80 mM) than CCh (1 μM)-induced contractions. R. webbiana EtOH extract exhibited complete antiperistalsis (21.55%), antidiarrheal (80.33%), and antisecretory (82.59±0.60) activities in vivo experiments at the dose of 300 mg/kg. CONCLUSION Thus, Rw. EtOH modulated multiple pathways, produced calcium antagonistic, anticholinergic, and phosphodiesterase inhibitory actions, and had antidiarrheal and bronchodilator effects.

Abstract
Background:Dryopteris ramosa is used as an old treatment for several diseases. D. ramose fronds are eaten to treat gastrointestinal (GIT) issues and as an antibiotic. However, there is a dearth of literature justifying its traditional use. Aims and objectives: the current work used biological and molecular docking studies to support traditional usage and elucidate D. ramosa's multitarget mechanism. Materials and methods: Bioactive compounds were docked in silico. Force displacement transducers coupled with a power lab data gathering system examined the effects of compounds on rabbit jejunum, trachea, and aorta tissues. Albino mice and rats were used for in vivo studies. Results: Bioactive compounds interacted with inflammation, asthma, and diarrhea genes, according to in silico studies. D. ramosa crude extract (Dr.Cr) calmed impulsive contractions and K+ (80 mM)-provoked contractions in the jejunum and tracheal tissue dose-dependently, showing the presence of the Ca++ channel-blocking (CCB) effect, further verified by the rightward parallel shift of CRCs equivalent to verapamil. Polarity-based fractionation showed spasmolytic activity in Dr.DCM and muscarinic receptors mediated spasmogenic activity in the Dr.Aq fraction. Dr.Cr vasoconstricted the aortic preparation, which was totally blocked by an angiotensin II receptor antagonist. This suggests that Dr. Cr's contractile effect is mediated through angiotensin receptors. In rats and mice, it showed anti-inflammatory and antidiarrheal action. Conclusion: This study supports the traditional medicinal uses of D. ramosa against GIT disorders and may be an important therapeutic agent in the future.

Via in silico, in vitro, and in vivo studies. JOURNAL OF ETHNOPHARMACOLOGY 2023; 305:116115. [PMID: 36587881 DOI: 10.1016/j.jep.2022.116115] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/23/2022] [Accepted: 12/24/2022] [Indexed: 06/17/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Berberis lycium Royle, a member of the Berberidaceae family, is a high-value medicinal plant with a documented history of usage in traditional medicine and has demonstrated significant therapeutic results among local populations throughout the globe. It is used traditionally in many parts of Pakistan to treat diarrhea, abdominal spasms, coughs, and chest problems. AIM OF THE STUDY To investigate the antispasmodic, bronchodilator, and antidiarrheal effects of B. lycium and its possible underlying mechanisms through in silico, in vitro, and in vivo studies. MATERIALS AND METHODS LC ESI-MS/MS analysis was used to identify bioactive components within the hydromethanolic extract of B. lycium. In silico studies, including network pharmacology and molecular docking, were utilized to investigate the antispasmodic and bronchodilator properties of the extract's bioactive components. In vitro pharmacological studies were conducted using isolated rabbit jejunum, trachea, urinary bladder, and rat ileum preparations. In vivo antidiarrheal activities were conducted in mice, including castor oil-induced diarrhea, intestinal transit, and castor oil-induced enteropooling. RESULTS The LC ESI-MS/MS analysis of the hydromethanolic extract of B. lycium identified 38 bioactive compounds. Network pharmacology study demonstrated that the mechanism of BLR for the treatment of diarrhea might involve IL1B, TLR4, PIK3R1, TNF, PTPRC, IL2, PIK3CD, and ABCB1, whereas, for respiratory ailments, it may involve PIK3CG, TRPV1, STAT3, ICAM1, ACE, PTGER2, PTGS2, TNF, MMP9, NOS2, IL2, CCR5, HRH1, and VDR. Molecular docking research revealed that chlorogenic acid, epigallocatechin, isorhamnetin, quinic acid, gallic acid, camptothecin, formononetin-7-O-glucoside, velutin, caffeic acid, and (S)-luteanine exhibited a higher docking score than dicyclomine with validated proteins of smooth muscle contractions such as CACB2_HUMAN, ACM3_HUMAN, MYLK_HUMAN, and PLCG1_HUMAN. In vitro investigations demonstrated that Blr.Cr, Blr.EtOAc, and Blr.Aq relaxed spontaneously contracting jejunum preparations; carbachol (1 μM)-induced and K+ (80 mM)-induced jejunum, trachea, and urinary bladder contractions in a concentration-dependent manner, similar to dicyclomine. Moreover, Blr.Cr, Blr.EtOAc, and Blr.Aq exhibited a rightward shift in Ca+2 and carbachol cumulative response curves, similar to dicyclomine, demonstrating the coexistence of antimuscarinic and Ca+2 antagonistic mechanisms due to the presence of alkaloids and flavonoids. In vivo antidiarrheal activities showed that the hydromethanolic extract was significantly effective against castor oil-induced diarrhea and castor oil-induced enteropooling, similar to loperamide, and charcoal meal intestinal transit, similar to atropine, in mice at doses of 50, 100, and 200 mg/kg body weight, which supports its traditional use in diarrhea. CONCLUSION The dual blocking mechanism of muscarinic receptors and Ca+2 channels behind the smooth muscle relaxing activity reveals the therapeutic relevance of B. lycium in diarrhea, abdominal spasms, coughs, and chest problems.

Abstract
BACKGROUND In addition to the nutritional benefits of Cucumis melo L., herbalists in Pakistan and India employ seeds to treat various ailments. This study aimed to determine the regulatory role of C. melo seeds in calcium-mediated smooth muscle contraction. METHODS We identified and quantified the phytochemicals of C. melo with LC ESI-MS/MS and HPLC, then conducted in vitro and in vivo tests to confirm the involvement in smooth muscle relaxation. Then, diarrhea-predominant irritable bowel syndrome gene datasets from NCBI GEO were acquired, DEGs and WGCNA followed by functional enrichment analysis. Next, molecular docking of key genes was performed. RESULTS The quantification of C. melo seeds revealed concentrations of rutin, kaempferol, and quercetin were 702.38 μg/g, 686.29 μg/g, and 658.41 μg/g, respectively. In vitro experiments revealed that C. melo seeds had a dose-dependent relaxant effect for potassium chloride (80 mM)-induced spastic contraction and exhibited calcium antagonistic response in calcium dose-response curves. In in vivo studies, Cm.EtOH exhibited antidiarrheal, antiperistaltic, and antisecretory effects. The functional enrichment of WGCNA and DEGs IBS-associated pathogenic genes, including those involved in calcium-mediated signaling, MAPK cascade, and inflammatory responses. MAPK1 and PIK3CG were identified as key genes with greater binding affinity with rutin, quercitrin, and kaempferol in molecular docking. CONCLUSIONS The bronchodilator and antidiarrheal effects of C. melo were produced by altering the regulatory genes of calcium-mediated smooth contraction.

Abstract
The eastern Himalayas, one of the important hotspots of global biodiversity, have a rich diversity of wild edible fruit trees. The fruits of these tree species have been consumed by the tribal people since time immemorial. However, there is limited information available on the biochemical and antioxidant properties of the fruits. Therefore, the present investigation was undertaken to study the physico-chemical and antioxidant properties of the nine most important wild fruit trees. Among the species, Pyrus pashia had the maximum fruit weight (37.83 g), while the highest juice (43.72%) and pulp content (84.67%) were noted in Haematocarpus validus and Myrica esculenta, respectively. Maximum total soluble solids (18.27%), total sugar (11.27%), moisture content (88.39%), ascorbic acid content (63.82 mg/100 g), total carotenoids (18.47 mg/100 g), and total monomeric anthocyanin (354.04 mg/100 g) were recorded in H. validus. Docynia indica had the highest total phenolic content (19.37 mg GAE/g), while H. validus recorded the highest total flavonoids and flavanol content. The antioxidant activities of the different fruits ranged from 0.17 to 0.67 IC50 for DPPH activity and 3.59-13.82 mg AAE/g for FRAP. These fruits had attractive pigmentation of both pulp and juice and were a good potential source for the extraction of natural edible color in the food industry. The fruits also possess high market prices; Prunus nepalensis fetched $ 34.10-$ 141.5 per tree. Therefore, these fruits are rich sources of antioxidants, pigments and have a high market value for livelihood and nutritional security.

Abstract
The present study aimed to determine the mechanisms responsible for calcium-mediated smooth muscle contractions in C. melo seeds. The phytochemicals of C. melo were identified and quantified with the aid of Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometric (LC/ESI-MS/MS) and high-performance liquid chromatography (HPLC), and then tested in-vitro and in vivo to confirm involvement in smooth muscle relaxation. Allergic asthma gene datasets were acquired from the NCBI gene expression omnibus (GEO) and differentially expressed gene (DEG) analysis, weighted gene co-expression network analysis (WGCNA), and functional enrichment analysis were conducted. Additionally, molecular docking of key genes was carried out. Kaempferol, rutin, and quercetin are identified as phytochemical constituents of C. melo seeds. Results indicated that C. melo seeds exhibit a dose-dependent relaxant effect for potassium chloride (80 mM)- induced spastic contraction and calcium antagonistic response in calcium dose-response curves. The functional enrichment of WGCNA and DEG asthma-associated pathogenic genes showed cytokine-mediated pathways and inflammatory responses. Furthermore, CACNA1A, IL2RB, and NOS2 were identified as key genes with greater binding affinity with rutin, quercitrin, and kaempferol in molecular docking. These results show that the bronchodilator and antidiarrheal effects of C. melo were produced by altering the regulatory genes of calcium-mediated smooth muscle contraction.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Citrullus lanatus (Thunb.) belongs to the ground family, Cucurbitaceae, known for edible fruit. Besides nutritional benefits, the traditional herbal practitioners in Pakistan and India used their seeds to treat gastrointestinal, respiratory, and urinary disorders. In Northern Sudan, its seeds are often used as a laxative. Its root is laxative and emetic at a high dose. Its seeds are also used to treat bedwetting and urinary tract obstruction. AIM OF THE STUDY This study aimed to elucidate the multi-target mechanisms of Citrullus lanatus seeds to treat asthma and diarrhea. The pharmacological experiments were designed and conducted, along with the pharmacology network and molecular docking predictions, to verify the seeds biopotency for antispasmodic and bronchodilator properties. METHODS LC ESI-MS/MS were performed to identify the potentially active compounds in hydroethanolic extract of Citrullus lanatus seeds, then to quantify them by HPLC. The quantified bioactive compounds of Citrullus lanatus, i.e., stigmasterol, quinic acid, malic acid, epicatechin, caffeic acid, rutin, p-coumaric acid, quercetin, ferulic acid, scopoletin, apigenin, and kaempferol were subjected to in silico studies for molecular docking. The hydroethanolic extract of Citrullus lanatus seeds was examined on isolated rabbit tissue, i.e., jejunum, trachea, and urinary bladder. The antiperistalsis, antidiarrheal and antisecretory studies were also performed in animal models. RESULTS In silico studies revealed that bioactive compounds of C. lanatus seeds interfere with asthma and diarrhea-associated target genes, which are a member of calcium mediate signaling, regulation of cytosolic calcium concentration, smooth muscle contraction, and inflammatory responses. It was also found that rutin, quercetin, kaempferol, and scopoletin were stronger binding to voltage-gated calcium channels, calcium/calmodulin-dependent protein kinase, myosin light chain kinase, and phosphoinositide phospholipase C, thus, exerting calcium channel blocker activity. The hydroethanolic extract of C. lanatus seeds exerted a concentration-dependent relaxant response for the spasmolytic response on isolated jejunum and trachea preparations and caused relaxation of spastic contraction of K+ (80 mM). Furthermore, it caused a non-parallel rightward shift with suppression of calcium concentration-response curves. In animal models, the Cl.EtOH showed antiperistalsis, antidiarrheal and antisecretory response. CONCLUSION Thus, we confirm Citrullus lanatus seeds have some medicinal effects by regulating the contractile response through target proteins of calcium mediates signaling and can be a promising component in the medical treatment for asthma and diarrhea.

Possible Mechanisms Underlying the Antispasmodic, Bronchodilator, and Antidiarrheal Activities of Polarity-Based Extracts of Cucumis sativus L. Seeds in In Silico, In Vitro, and In Vivo Studies. Pharmaceuticals (Basel) 2022; 15:ph15050641. [PMID: 35631468 PMCID: PMC9143705 DOI: 10.3390/ph15050641] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 04/29/2022] [Accepted: 05/09/2022] [Indexed: 02/06/2023] Open
Abstract
Apart from the nutritional value, Cucumis sativus L. has also been used in the traditional medicine of Iran, Pakistan, and India. Its seeds are used by herbalists to treat gastrointestinal, respiratory, and urinary problems. However, more investigations are required to explain its mechanisms for treating GI, respiratory, and urinary diseases. Accordingly, the aim of the present work was to investigate the antispasmodic, bronchodilator, and antidiarrheal activities of C. sativus seeds extracts and the underlying mechanisms of action. For this purpose, sequential extracts of C. sativus seeds were prepared in n-hexane, dichloromethane, ethanol, and water. Bioactive compounds in C. sativus seed extracts were identified and quantified by utilizing LC ESI–MS/MS and HPLC. Moreover, network pharmacology and molecular docking were employed to examine the antispasmodic and bronchodilator effects of the bioactive substances in the extracts. In vitro and in vivo experiments were also conducted to validate the mechanistic insights gained from the in silico analysis. Results indicated the presence of kaempferol with a concentration of 813.74 µg/g (highest concentration) in the seed extract of C. sativus, followed by quercetin (713.83 µg/g), narcissin (681.87 µg/g), and orientin (676.19 µg/g). In silico investigations demonstrated that the bioactive chemicals in C. sativus seeds inhibited the expression of the target genes involved in smooth muscle contraction and calcium-mediated signaling. Sequential seed extracts of C. sativus caused a dose-dependent relaxant response for spasmolytic reaction and resulted in a relaxation of K+ (80 mM) spastic contraction. In animal models, C. sativus seed extracts exhibited partial or complete antiperistalsis, antidiarrheal, and antisecretory actions. By modulating the contractile response through calcium-mediated signaling target proteins, C. sativus seeds generated bronchodilator, antispasmodic, and antidiarrheal therapeutic effects.

Abstract
BACKGROUND Citrullus lanatus (Thunb.) is a member of the Cucurbitaceae family, commonly farmed as an edible vegetable around the globe. It has been used in traditional therapies in addition to nutritional advantages. Traditional herbal practitioners employ C. lanatus seeds to treat gastrointestinal, respiratory, and urinary diseases in Pakistan and India. However, more investigation is needed to understand the effect of C. lanatus seeds on treating gastrointestinal, respiratory, and urinary disorders. PURPOSE This research aimed to use network pharmacology and molecular docking to understand multi-target mechanisms of C. lanatus seeds against asthma and diarrhea and to validate its effects using biological tests to investigate antispasmodic and bronchodilator capabilities. METHODS The ground seeds of C. lanatus were extracted in hexane, dichloromethane, ethanol, and aqueous for sequential extracts. The bioactive components in sequential extracts of C. lanatus seeds were identified using LC ESI-MS/MS, and specific compounds were quantified using HPLC. The quantified bioactive compounds of C. lanatus were subjected to in silico studies for network pharmacology and molecular docking to elucidate their role in antispasmodic and bronchodilator properties. The sequential extracts were tested on isolated rabbit tissue, i.e., jejunum, trachea, and urinary bladder. The antiperistalsis, antidiarrheal and antisecretory studies were also performed in animal models. RESULTS In silico studies indicate that bioactive chemicals from sequential extracts of C. lanatus seeds interfere with asthma and diarrhea-associated pathogenic genes. Those are members of calcium mediate signaling, cholinergic synapse, regulation of cytosolic calcium concentration, smooth muscle contraction, and inflammatory responses. It was also found that rutin, quercitrin, stearic acid, umbelliferone, and kaempferol were stronger binding to voltage-gated calcium channels and muscarinic M3 receptor, thus exerting calcium channel blocker activity and cholinergic receptor stimulant response. On isolated jejunum, trachea, and urinary preparations, sequential extracts of C. lanatus seeds elicited the spasmolytic response and showed the relaxation of spastic contractions of K+ (80 mM) and carbachol (1 µM). Furthermore, it induced a non-parallel rightward shift in calcium concentration-response curves with suppression. In animal models, C. lanatus seed extracts exhibited partially or completely antiperistalsis, antidiarrheal, and antisecretory effects. CONCLUSION Thus, Citrullus lanatus had therapeutic benefits by modulating the contractile response through calcium-mediated signaling target proteins, hence exerting bronchodilator and antidiarrheal properties. The current study provides evidence for further mechanistic studies and the development of C. lanatus seeds as a potential therapeutic intervention for patients with gastrointestinal, respiratory, and urinary disorders.

Abstract
BACKGROUND Pears have been world-widely used as a sweet and nutritious food and a folk medicine for more than two millennia. METHODS We conducted a review from ancient literatures to current reports to extract evidence-based functions of pears. RESULTS We found that pears have many active compounds, e.g., flavonoids, triterpenoids, and phenolic acids including arbutin, chlorogenic acid, malaxinic acid, etc. Most of researchers agree that the beneficial compounds are concentrated in the peels. From various in vitro, in vivo, and human studies, the medicinal functions of pears can be summarized as anti-diabetic,-obese, -hyperlipidemic, -inflammatory, -mutagenic, and -carcinogenic effects, detoxification of xenobiotics, respiratory and cardio-protective effects, and skin whitening effects. Therefore, pears seem to be even effective for prevention from Covid-19 or PM2.5 among high susceptible people with multiple underlying diseases. CONCLUSION For the current or post Covid-19 era, pears have potential for functional food or medicine for both of communicable and non-communicable disease.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The conventional naturopaths of Punjab Province (Pakistan) have trivial usage of Anagallis arvensis Linn.(Primulaceae) for cure of diarrhea, constipation, asthma as well as hypertension. AIM Present research was focused to discover comprehensive mechanism of spasmogenic, spasmolytic, bronchorelaxant and hypotensive folkloric usage of Anagallis arvensis Linn.. METHODOLOGY The crude extract of Anagallis arvensis Linn. (Aa.Cr) & its (aqueous & organic) portions tested in-vitro on isolated jejunum, ileum, trachea, aorta, paired atria preparations as well as in-vivo in mice & normotensive anaesthetized rats. The responses have been noted by transducers (isotonic & isometric) coupled to Power Lab. RESULT Anagallis arvensis Linn. (Aa.Cr; crude aqueous-alcoholic extract) produced contractile action at low concentrations but relaxant action was observed by increasing concentrations on spontaneous contractions of isolated jejunum of rabbit. But, pre-treatment of tissue with atropine prior extract caused suppression of contractile effect indicating presence of cholinergic muscarinic response of Aa.Cr. It also triggered relaxation of high Potassium -stimulated contractions of jejunum with subsequent non-parallel right move in Ca++ CRCs. Moreover, Aa.Cr relaxed carbachol - & high Potassium - stimulated contractions in trachea of rabbit but observed relaxant effect was powerful against CCh (1 μM)- stimulated contractions with rightside parallel move of CCh-curves succeeded by non-parallel move, like Dicyclomine, having dual activities. The Aa.Cr also showed relaxant result on Phenylephrine and High Potassium -prompted contractions in endothelium intact aorta. The fractionation revealed segregations of contractile & relaxant effects in relevant aqueous & organic portions. The Intravenous administration of Aa.Cr to ketamine-diazepam anaesthetized normo-tensive albino rats resulted in decreased MABP, SBP & DBP. The Aa.Cr applied negative (-) inotropic & chronotropic action on paired atria. The Aa.Cr also exhibited anti-diarrheal action in mice against castor oil prompted diarrhea and also mitigated distance covered by charcoal meal in gastrointestinal tract in a manner comparable with loperamide. CONCLUSION These results revealed presence of CCB and selective muscarinic agonist activity in Aa.Cr, hence validating folkloric practice of Anagallis arvensis Linn. in diarrhea, constipation, asthma & hypertension.

Abstract
Traditionally, in the Southern Asian countries, Psidium cattleyanum is a widely used plant for the management of various ailments such as gastrointestinal, respiratory, and cardiac disorders, but it lacks proof on a scientific basis, and therefore, this is the major emphasis of the current research work. Crude extract of Psidium cattleyanum (Pc.Cr) was preliminary analyzed for the presence of different classes of bioactive molecules. The aqueous and dichloromethane fractions of Pc.Cr were subjected to in vitro and in vivo studies. It was applied at variable concentrations (0.1-10 mg/ml) to isolated rabbit jejunum to investigate spasmolytic effect. Concentration dependent curves of calcium were constructed to check the calcium channel antagonistic activity. For the evaluation of tracheorelaxant activity, isolated tracheal tissue was treated with High-K+ (80 mM) and carbachol (CCh) and then challenged cumulatively with Pc.Cr. To study the antidiarrheal effect of the plant extract, castor oil-induced diarrhea model was adopted. For evaluation of the hypotensive effect of Pc.Cr, it was given intravenously to preanesthetized normotensive rats, and the response was recorded using pressure transducer. Platelet rich plasma was used for the assessment of the antiplatelet activity when challenged with purinergic and adrenergic agonists. Concentration-dependent inhibition of spontaneous and High-K+ mediated contractions in isolated jejunum was observed by the application of Pc.Cr. Contractions induced in isolated tracheal tissue by High-K+ and CCh were inhibited by application of Pc.Cr to these tissues. Similarly, application of Pc.Cr to High-K+ and phenylephrine (PE) treated aortic strips resulted in vasodilation. Platelet aggregation inhibition was shown by Pc.Cr against adenosine diphosphate (ADP) only. The antidiarrheal effect was observed as a reduction in the total number of feces in Pc.Cr-treated mice when given castor oil. Dose-dependent hypotension was seen in normotensive rats when treated with Pc.Cr intravenously. This study showed the spasmolytic, tracheorelaxant, vasodilator, platelet aggregation inhibitory, antidiarrheal, and hypotensive activities of P. cattleyanum which may be due to the blockage of calcium channels, but the involvement of any other pathway cannot be ignored.

Abstract
OBJECTIVE Pyrus pashia has traditionally been used as a therapeutic agent including sedative. In this regard, hydroethanolic extract of Pyrus pashia (HEPP) was screened for phytochemical investigation, acute toxicity, and sedative-hypnotic activity to provide a scientific rationale to its ethno-medicinal uses. METHODS Mice were used in acute toxicity test; sedative potential was observed in open field test while thiopental-induced sleeping time and barbiturate-induced sleeping time tests were used for the assessment of hypnotic like effects of HEPP. Various phytochemical groups were detected in preliminary phytochemical tests. RESULTS In acute toxicity study, the extract was found safe up to 1g/kg while the extract caused 50% death at 1500 mg/kg. In all animal models, the extract had shown sedative and hypnotic effects but the most significant effect observed at increased dose in comparison with standard diazepam-treated group. In open field test, the extract at doses of 200 and 400 mg/kg, there is mild decrease in number of lines crossed by tested animals (mice) while significant reduction shown at 600 mg/kg compared with diazepam-treated group at dose 0.5 mg/kg. In phytochemical investigation HEPP subjected to different phytochemical tests. From the thoroughly study, it is revealed that these constituents mainly participating in sedation and hypnosis. CONCLUSIONS The results of the present study showed significant sedative-hypnotic effects of the HEPP in mice and that the central benzodiazepine receptors are involved in the sedative-hypnotic effects of this plant.

Abstract
Domestic animals play a very important role in the human civilization. Besides human being, plants are used as medicines for many domestic animals. The therapeutic practices are very common among the tribes of Chamla, rich in ethnoveterinary medicinal plants. Due to poor availability of modern healthcare facilities and poverty of indigenous people, they depend on local medicinal plants for the healthcare of their domestic animals. This study is the first attempt to document the indigenous knowledge and evaluate the conservation status of medicinal plants and practices of herbal remedies by the local people of Chamla Valley in the treatment of their livestock. Semi-structured questionnaire was used and 120 local inhabitants were interviewed to note the traditional practices regarding plant species uses. Well-known statistical indices, Use Value formula and Relative Frequency Citations were used for quantification of the recorded data. It was observed that 50 medicinal plants belonging to 38 families were reported, where Poaceae was the most cited. The common livestock are goats, sheep, buffalos, cows, bulls, and donkeys. Most of the herbs, which are used in livestock treatment, are wild and few plants are cultivated. The common livestock diseases are red water, 3 days sickness, diarrhea, tympany, and indigestion among others. Most of the plants are used in fresh condition. According to the results, Brassica nigra was used for placenta retention, Butea monosperma for constipation, Calotropis procera for indigestion and 3 days sickness. Canabis sativa, Cedrella serrata, Allium sativum, and Origanum vulgare were used for fever. The traditional plant collection techniques have resulted in huge losses of these valuable plant resources. The ethnobotanical conservation assessment revealed that due to increased exploitation and un-sustainable harvesting, 49% of these economically valued medicinal plant species are decreasing in last 30 years. Some of the plants are only present on high altitudes while they had been finished in the foothills like Paeonia emodi and Berberis lycium. Lack of scientific knowledge, ignorance, poverty, and joblessness, as well as land development, construction and fires, add more pressure on flora and fauna of the area and various species are under the threat of extinction.

Abstract
Local people in the Sudhnoti district of Pakistan share a rich practice of traditional medicine for the treatment of a variety of ailments. We selected nine plants from the Sudhnoti ethnopharmacological tradition used for the treatment of infectious and inflammatory disease. Our aim was to evaluate the in vitro anti-infective potential of extracts from these species against multidrug-resistant (MDR) ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanii, Pseudomonas aeruginosa, and Enterobacter species) pathogens. Plant specimens were collected in the Sudhnoti district of Pakistan and vouchers deposited in Pakistan and the USA. Dried bulk specimens were ground into a fine powder and extracted by aqueous decoction and maceration in ethanol. Extracts were assessed for growth inhibitory activity against ESKAPE pathogens and biofilm and quorum sensing activity was assessed in Staphylococcus aureus. Cytotoxicity to human cells was assessed via a lactate dehydrogenase assay of treated human keratinocytes (HaCaTs). Four ethanolic extracts (Zanthoxylum armatum, Adiantum capillus-venaris, Artemisia absinthium, and Martynia annua) inhibited the growth of MDR strains of ESKAPE pathogens (IC50: 256 μg mL-1). All extracts, with the exception of Pyrus pashia and M. annua, exhibited significant quorum quenching in a reporter strain for S. aureus agr I. The ethanolic extract of Z. armatum fruits (Extract 1290) inhibited quorum sensing (IC50 32-256 μg mL-1) in S. aureus reporter strains for agr I-III. The quorum quenching activity of extract 1290 was validated by detection of δ-toxin in the bacterial supernatant, with concentrations of 64-256 μg mL-1 sufficient to yield a significant drop in δ-toxin production. None of the extracts inhibited S. aureus biofilm formation at sub-inhibitory concentrations for growth. All extracts were well tolerated by human keratinocytes (LD50 ≥ 256 μg mL-1). Chemical analysis of extract 1290 by liquid chromatography-Fourier transform mass spectrometry (LC-FTMS) revealed the presence of 29 compounds, including eight with putative structural matches. In conclusion, five out of the nine selected anti-infective medicinal plants exhibited growth inhibitory activity against at least one MDR ESKAPE pathogen at concentrations not harmful to human keratinocytes. Furthermore, Z. armatum was identified as a source of quorum quenching natural products and further bioassay-guided fractionation of this species is merited.

Abstract
Objective: The traditional use of the ethanolic extract of the fruit of Pyrus pashia (EPP) as a potential anticonvulsant was validated using experimental animal models. Furthermore, the anticonvulsant activity of isolated chrysin was investigated against experimental animal models to draw a possible therapeutic mechanism of EPP. Additionally, the safety profile of chrysin was evaluated to explore the possible therapeutic alternative in the management of epilepsy. Method: The anticonvulsant activity in terms of duration of onset of hind limb tonic extension and convulsion of standardized EPP was evaluated against maximal electroshock (MES) and pentylenetetrazole (PTZ) model of experimental epilepsy respectively. Furthermore, the anticonvulsant activity and electrophysiological properties of chrysin was investigated in addition to antioxidant activity against PTZ-induced convulsion in experimental animals. Moreover, the neurotoxic profile of the chrysin was assessed in terms of duration of movement and running in photoactometer and rotarod apparatus, respectively. Results: EPP (100, 200, and 400 mg/kg) exhibited significant anticonvulsant activity against an acute model of MES and PTZ-induced convulsions in experimental animals. Furthermore, chrysin (2.5, 5, and 10 mg/kg) also exhibited significant anticonvulsant activity against PTZ-induced convulsions in rats. In addition, chrysin did not exhibit sedative-like behavior in experimental rodents. Discussion: EPP could be considered as a potential and alternative therapeutic option in the management of epilepsy.

Abstract
OBJECTIVE To investigate the pharmacological basis of its uses of Phyla nodiflora (P. nodiflora) for the treatment of anomalies predominantly by smooth muscle containing tissues such as gastrointestinal/vascular/broncho spasm and cardiovascular modulation. METHODS The crude hydroalcoholic extract of P. nodiflora (Pn.Cr) and its fractions were evaluated on isolated rabbit jejunum, rat trachea, aorta and atrium. To access the contractile or relaxant effects of testing materials, the tissues were mounted in isolated organ bath and responses were recorded with transducers coupled with data acquisition system. BALB/c mice were challenged with castor oil for the assessment of in-vivo antidiarrheal activity. Normotensive rats were used for in-vivo hypotensive study. RESULTS Hydroalcoholic extract of Pn.Cr at variable concentrations inhibited the natural spontaneous rhythm and 80 mmol/L K+ mediated contractions in isolated segment of jejunum with EC50 values of 3.18 and 1.91 mg/mL respectively. Verapamil, a Ca2+ channel blocker, demonstrated akin pattern in jejunum and therefore possibly suggesting calcium blocking activity. On isolated rat tracheal tissue, Pn.Cr showed relaxation of high-K+ and carbachol mediated contractions (EC50 values: 1.24 and 2.42 mg/mL). Pn.Cr treatment relaxed the rat aortic ring in a cumulative doses with high-K+ and phenylephrine-induced contractions (EC50 values 0.25 and 0.92 mg/mL). Activity based fractionation of Pn.Cr showed that dichloromethane fraction was more potent for relaxing the tissues spasm compared to aqueous fraction. In-vivo experiments, significant protection by Pn.Cr (P < 0.05) was observed in castor oil-induced diarrhea (50-500 mg/kg) whereas hypotensive effect in anesthetized rats was seen at the dose range of 1-10 mg/kg of Pn.Cr (P < 0.05). CONCLUSION This study suggests the blockage of calcium channel in the smooth muscles as a pharmacological application to make usage of P. nodiflora in the management of diarrhea, asthma and hypotensive effect.

Abstract
ETHNO PHARMACOLOGICAL RELEVANCE Ethno medicinal traditional knowledge regarding the uses of indigenous medicinal plants used for various human digestive disorders are mostly known to the elder community members. As the young generation is not much aware about such vital traditional medicinal practice because they rely on elders. AIM OF STUDY To document, accumulate and widely disseminate the massive indigenous knowledge of century's practiced therapeutic uses of medicinal plants by the local people living in this remote area. MATERIALS AND METHODS A total of 63 local inhabitants (39 males and 24 females) were interviewed through a structured questionnaire. The data obtained were quantitatively analyzed through the use value (UVi), fidelity level index (FL%) and relative frequency citations (RFCs), consensus index (CI%) and informant consensus factor (FIC). For novel uses all the plants were checked with previously published articles on same disease by analyzing through Jaccard index (JI) and Sorensen's similarity index (QS). Plants specimen were preserved, mounted and labeled on the herbarium sheets, cataloged and deposited with voucher numbers in Hazara University Herbarium, Mansehra, Pakistan (HUP). RESULTS 44 plant species belonging to 44 genera and 28 families were documented in the current study. These medicinal plant species were used commonly as an ethno medicine against 26 various digestive disorders out of which most frequently occurred are; stomach ache, diarrhea, indigestion, constipation and inflammation etc. Herbaceous plant species were the dominant among plants studied which were 64% of the total plants, followed by trees (20%) and shrubs (16%). Lamiaceae was the leading family among collected medicinal plant species (13.6%). Maximum medicinal plant species were used for treatment of stomach ache (11.7%), diarrhea and indigestion (10.9% each). Most widely used parts were leaves (41% citations), fruit and whole plant (12% citations each) for medication of various digestive problems by the traditional drivers. Dominated medicinal plants with most use values were Ficus carica having (UVi=0.90) and Trifolium repens (UVi=0.84). Based on the RFC values, the most cited medicinal plant species by the traditional drivers were Ficus carica (0.43) and Berberis lycium (0.41), while most respondents percentage was noticed for same plant species calculated through consensus index (CI%=42.9% and 41.3%) respectively. The medicinal plant species with highest fidelity level was of Grewia optiva, Juglans regia and Sorbaria tomentosa each cited 100% for anthelmintic, easy digestion and Diarrhea respectively. Due to representation by only single medicinal plant taxa (Nt=1), the digestive diseases viz. cholera, colon cancer, emetic, internal injuries, kill microorganisms, Soothing, tumor and urine suppression had maximum FIC value. The analytical result reveals that 57% of medicinal plant species were reported for the first time regarding their uses. new medicinal uses of Anaphalis contorta, Caltha palustris, Pinus wallichiana, Plantago himalaica were recorded for the first time from Pakistan and Aralia cachemirica, Bupleurum longicaule, Pleurospermum stellatum, Potentilla argentea and Juglans regia across the globe for currently reported medicinal uses. Besides this, all the mentioned plant species were reported for the first time for digestive disorders from Manoor Valley as no single study up-till now has been conducted ethno medicinally. CONCLUSION The present study revealed the importance to document and launch list of all the possible plants that are used in traditional medicinal practices against digestive disorders in the unexplored study area and to show the important medicinal plants for future biological, phytochemical and pharmacological experimentation regarding digestive problems.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 15:319. [PMID: 26354022 PMCID: PMC4564972 DOI: 10.1186/s12906-015-0837-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/11/2015] [Accepted: 08/28/2015] [Indexed: 11/10/2022]
Abstract
Background Murraya paniculata is traditionally used for management of gut, air way and cardiovascular disorders. The study was conducted for provision of pharmacological rationalization for folkloric uses of Murraya paniculata in gut, air way and cardiovascular problems. Methods Aqueous-ethanolic extract of Mp.Cr was tested using in vitro techniques on isolated tissue of rabbit (jejunum, trachea and aorta) to detect the possible presence of spasmolytic activity. The responses of tissues were recorded using isotonic transducers coupled with PowerLab data acquisition system. Results Application of the extract of Mp.Cr relaxed spontaneous and high K+ (80mM)-induced contraction in rabbit jejunum preparation. Because it shifted the CRCs (Calcium response curve) towards the right side so the possible blockade was of calcium channel similar to verapamil. In rabbit trachea, extract of Mp.Cr produced relaxation of carbachol and high K+ induced contractions. When plant extract was checked further on isolated aorta for its possible vasodilator effect, it caused relaxation of phenylephrine and high K+-induced spastic contractions at different doses. Conclusion These results indicate that Murraya paniculata shows anti-spasmodic, bronchodilator and vasodilator activity facilitated through Ca++ antagonist mechanisms.
