Exploring the Bioactive Compounds in Some Apple Vinegar Samples and Their Biological Activities. PLANTS (BASEL, SWITZERLAND) 2023; 12:3850. [PMID: 38005745 PMCID: PMC10675503 DOI: 10.3390/plants12223850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 11/01/2023] [Accepted: 11/09/2023] [Indexed: 11/26/2023]
Abstract
Apple vinegar is highly recommended for nutrition due to its health benefits and bioactive components. However, the apple cultivar greatly influences the quality of the vinegar. In this research, our focus was on examining the impact of four different apple cultivars on the physicochemical attributes, chemical composition, as well as biological properties-including antidepressant and anti-inflammatory activities-of vinegar. Interestingly, the physicochemical properties of vinegar and the contents of acetic acid and polyphenols depend on the apple cultivars. HPLC chromatographic analysis showed that citric acid (820.62-193.63 mg/100 g) and gallic acid (285.70-54.40 µg/g) were mostly abundant in the vinegar samples. The in vivo results showed that administration of Golden Delicious apple vinegar (10 mL/kg) to adult Wistar rats reduced carrageenan-induced inflammation by 37.50%. The same vinegar sample exhibited a significant antidepressant effect by reducing the rats' immobility time by 31.07% in the forced swimming test. Due to its high acidity, Golden Delicious vinegar was found to be more effective against bacteria, particularly Bacillus subtilis and Candida albicans, resulting in a MIC value of 31.81 mg/mL. Furthermore, the antioxidant activity of various vinegar samples was found to be powerful, displaying optimal values of IC50 = 65.20 mg/mL, 85.83%, and 26.45 AAE/g in the DPPH, β-carotene decolorization and TAC assays, respectively. In conclusion, the apple cultivars used in this study impact the chemical composition and biological activities of vinegar, which may help demonstrate the importance of raw material selection for the production of vinegar.

Abstract
It has long been found that hyaluronidases exist in a variety of organisms, playing their roles in various biological processes including infection, envenomation and metabolic regulation through degrading hyaluronan. However, exploiting them as a bioresource for specific applications had not been extensively studied until the latest decades. In recent years, new application scenarios have been developed, which extended the field of application, and emphasized the research value of hyaluronidase. This critical review comprehensively summarizes existing studies on hyaluronidase from different source, particularly in their structures, action patterns, and biological functions in human and mammals. Furthermore, we give in-depth insight into the resource mining and protein engineering process of hyaluronidase, as well as strategies for their high-level production, indicating that mixed strategies should be adopted to obtain well-performing hyaluronidase with efficiency. In addition, advances in application of hyaluronidase were summarized and discussed. Finally, prospects for future researches are proposed, highlighting the importance of further investigation into the characteristics of hyaluronidases, and the necessity of investigating their products for the development of their application value.

Abstract
Burns constitute a major challenge in medical science, and plants can be part of the solution. Dittrichia viscosa L. (Asteraceae) and Marrubium vulgare L. (Lamiaceae) are widely used in Moroccan traditional medicine to treat several diseases and possess high potency to cure wounds. This study aimed to investigate in vivo the analgesic, anti-inflammatory, and burn-healing effects of both plants and their mixture. The hydro-ethanolic extract of both plants was analyzed using high-performance liquid chromatography with diode-array detection (HPLC-DAD). Burns were conducted on dorsal part of rats, and the wound healing process was evaluated during 21 days. Gallic acid, caffeic acid, ferulic acid, and quercetin were identified in M. vulgare extract. The analysis recorded the presence of caffeic acid, rosmarinic acid, rutin, and quercetin in D. viscosa. The group treated with the mixture showed the lowest abdominal contractions (30.4 ± 7.52) with the highest percentage of inhibition (69.12 ± 7.04%). The inhibition of paw inflammation for M. vulgare was 47.65%, followed by D. viscosa (33.86%) and the mixture (30.41%). The mixture showed the highest wound contraction at day 7 (33.16 ± 14.33%) and day 14 (87.54 ± 3.98%). D. viscosa showed the highest wound contraction on the 21st day (99.28 ± 0.44%). In conclusion, both plants and their combination showed promising results for burn healing.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27030827. [PMID: 35164090 PMCID: PMC8840727 DOI: 10.3390/molecules27030827] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 01/22/2022] [Accepted: 01/24/2022] [Indexed: 01/09/2023]
Abstract
The high biological potential of polyphenols encourages the search for new natural sources of and biomedical applications for these compounds. Rhododendron luteum Sweet was previously reported to contain pharmaceutically active polyphenols. The present research investigates the polyphenolic fractions in R. luteum leaves, including a determination of the free and bound phenolic acid and flavonoid contents and their anti-inflammatory and antioxidant activities. LC-ESI-MS/MS (liquid chromatography/electrospray ionization triple quadrupole mass spectrometry) analysis revealed a great abundance of free (e.g., 5-O-caffeoylquinic acid, ferulic acid, protocatechuic acid, catechin, and dihydromyricetin) and bound (e.g., caffeic acid, p-coumaric, protocatechuic acid, myricetin, quercetin) phenolics. The R. luteum samples exhibited high anti-inflammatory potential in lipoxygenase (IC50: 0.33 ± 0.01-2.96 ± 0.06 mg dry extract (DE)/mL) and hyaluronidase (IC50: 78.76 ± 2.09 - 429.07 ± 31.08 µg DE/mL) inhibition capacity assays. Some samples also had the ability to inhibit cyclooxygenase 1 (IC50: 311.8 ± 10.95 µg DE/mL) and cyclooxygenase 2 (IC50: 53.40 ± 5.07; 608.09 ± 14.78 µg DE/mL). All fractions showed excellent antioxidant activity in the Oxygen Radical Absorbance Capacity (ORAC) assay (5.76-221.81 g Trolox/g DE), ABTS•+ radical scavenging ability (0.62 ± 0.03 - 5.09 ± 0.23 g Trolox/g DE), and moderate ion (Fe2+) chelating power. This paper expands our knowledge of the phytochemistry and pharmacological activity of R. luteum polyphenols. It reveals, for the first time, the presence of dihydromyricetin, afzelin, and laricitrin in the plant material. It indicates biologically active polyphenolic fractions that should be further investigated or which could be efficiently used in pharmaceutical, cosmetic, or nutraceutical applications.

Ethyl acetate fraction from Nymphaea hybrida Peck modulates inflammatory responses in LPS-stimulated RAW 264.7 cells and acute inflammation murine models. JOURNAL OF ETHNOPHARMACOLOGY 2021; 269:113698. [PMID: 33338590 DOI: 10.1016/j.jep.2020.113698] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Revised: 12/11/2020] [Accepted: 12/11/2020] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nymphaea hybrida Peck is used as a traditional medicinal herb for treating pain and inflammatory diseases, and known for its ornamental value and as a hot drink. However, the effects of N. hybrida polar fractions on lipopolysaccharide (LPS)-induced in vitro inflammation model and acute inflammation murine models have yet to be evaluated. AIM OF THE STUDY The aim of this study was to elucidate the anti-inflammatory effects of N. hybrida ethanol extract (NHE) and its polar fractions: petroleum ether (PE), methylene chloride (MC), ethyl acetate (EA), methanol (ME), and water (WA). The underlying molecular mechanisms of active fraction in LPS-stimulated RAW 264.7 murine macrophages were further investigated. MATERIAL AND METHODS Fractions with potential anti-inflammatory effects were screened using direct nitric oxide (NO) radical scavenging and cyclooxygenase (COX)-2 inhibition assays in vitro. The anti-inflammatory properties of potential fraction were evaluated in LPS-stimulated RAW264.7 cells, xylene-induced ear edema, carrageenan-induced paw edema and xylene-induced Evans blue exudation of acute inflammation murine models. The regulation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways were investigated using western blotting and immunofluorescence. RESULTS Compared to other polar fractions, NHE-EA displayed higher phenol and flavonoid content, and exerted greater activity in direct NO radical scavenging and COX-2 inhibition assay in vitro. NHE-EA markedly decreased the levels of inflammatory mediators, NO and prostaglandin E2 (PGE2), by suppressing the over-expression of inducible nitric oxide synthase (iNOS) and COX-2 in LPS-stimulated RAW264.7 cells. The NHE-EA fraction dose-dependently alleviated over-elevation of LPS-associated intracellular calcium and decreased the abnormal secretion of pro-inflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, and interferon-γ (IFN-γ). The combination with NHE-EA effectively attenuated the activation and nuclear translocation of NF-κB p65, and the phosphorylation of extracellular signal-regulated kinases (ERK), c-Jun N-terminal kinases (JNK), and p38 kinases of MAPK pathways. NHE-EA could significantly ameliorate the degree of swelling of the mice ear and paw, the skin exudation of Evans blue and the excessive secretion of inflammatory cytokines. CONCLUSION Our results demonstrated that NHE-EA was the most active polar fraction of N. hybrida extracts. It inhibited the LPS-associated inflammatory response by blocking the activation of NF-κB and MAPKs pathways in RAW264.7 cells. It also effectively alleviated the inflammatory response of acute inflammation. These results indicated the role of NHE-EA as adjuvants and their potential role in alternative strategy for the treatment of inflammatory diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viburnum taitoense Hayata has been used as folk medicine by the minority people in Southwestern China for a long history, especially in Guangxi Zhuang Autonomous Region. The minority in Guangxi including Zhuang, Miao and Yao people use the ethanol extract of V. taitoense Hayata to treat the fracture, kill the pain of rheumatism because of its definite therapeutic effects. AIM OF THE STUDY So far, the scientific investigation of V. taitoense Hayata is done very little. Here, we first prepared the ethyl acetate extract of V. taitoense (EEVt), secondly measured the contents of phenols, flavonoids, and terpenoids in EEVt, and thirdly, the anti-inflammatory and analgesic activities of EEVt were investigated by invitro model of RAW 264.7 cells and invivo models of inflammation and pain in rats and mice. MATERIALS AND METHODS The contents of phenols, flavonoids, and terpenoids in EEVt were determined by UV spectrophotometry, respectively. The anti-inflammatory effect of EEVt (5, 25, 50, 100, and 200 μg/mL) in vitro was tested by determining its inhibitory effect on the nitric oxide production of RAW264.7 cells activated by lipopolysaccharide (LPS). The anti-inflammatory and analgesic effects of EEVt in vivo were investigated in the following experimental rats and mice models: carrageenan-induced paw edema, corton-oil-induced ear edema, acetic acid writhing test, and formalin pain test. RESULTS The contents of total phenolic, total flavonoids, and total triterpenoids in V. taitoense were measured to be 3.46 ± 0.04%, 2.38 ± 0.04%, and 14.96 ± 0.17%, respectively. In vitro test showed that EEVt at different tested dosages (5, 25, 50, 100, and 200 μg/mL) had no significant toxicity to RAW264.7 macrophages. At dosages of 37.5 and 75 μg/mL of EEVt significant inhibitory (p < 0.001) on the productions of nitric oxide (NO). High dosage (200 μg/mL) of EEVt displayed highly significant inhibitory (p < 0.001) on the productions of proinflammatory cytokines IL-6, IL-1β, and TNF-α from the LPS-induced RAW264.7 macrophages. EEVt showed obvious anti-inflammatory activity at different time points after carrageenan injection (p < 0.05) in vivo test, and its anti-inflammatory activity reached the strongest 4 h. Similarly, through the ear swelling test, EEVt (200 mg/kg) showed significant (p < 0.05) anti-inflammatory activity. Besides, formalin and acetic acid writhing experiments also showed that EEVt has significant (p < 0.05) analgesic activity. CONCLUSION EEVt was confirmed to be definite anti-inflammatory and analgesic effects, and the phytochemicals of EEVt was disclosed to be rich in triterpenoids, which was worthy to be further investigated.

Abstract
Hypertension is a dominant risk factor for the development of cardiovascular, kidney, and eye diseases. In Africa, it increasingly leads to hospitalisation and a strain on the public health system. However, rather than modern medicine, African traditional healers are the first choice for most South Africans. Therefore, this study is aimed at gathering information on herbal remedies traditionally used for the treatment of high blood pressure in Vhavenda, South Africa, and comparing this information with reports in the literature regarding plants used to manage high blood pressure. An ethnobotanical survey was carried out in Vhembe district and its environs with 53 herbalists and indigenous people aged between 36 and 66 years from January to October 2019 using a semistructured questionnaire. The plants were collected with each respondent; they were authenticated and kept in herbarium. A total of 51 different plants were mentioned as being most commonly used for hypertension treatment. Of these, 44 plants were identified, with those from the Fabaceae family followed by plants from the Celastraceae family being commonly mentioned. Of these, the Elaeodendron transvaalense, Tabernaemontana elegans, Elephantorrhiza elephantina, and Aloe vossii were commonly cited species. According to the literature data, most of the identified plants are yet to be scientifically investigated for the treatment of hypertension, whereas only preliminary investigations have been carried out on other plants, suggesting that these preliminary investigations may have highlight promising antihypertensive activities in vitro that are indicative of their potential as antihypertensive drugs. Therefore, there is a need to scientifically investigate the antihypertensive potentials of these plants as a potential source of antihypertensive treatment and compounds.
