Abstract:This review highlights the increasing interest in one of the natural compounds called saponins, for their potential therapeutic applications in addressing inflammation which is a key factor in various chronic diseases. It delves into the molecular mechanisms responsible for the anti‐inflammatory effects of these amphiphilic compounds, prevalent in plant‐based foods and marine organisms. Their structures vary with soap‐like properties influencing historical uses in traditional medicine and sparking renewed scie… Show more
The Fabaceae (Leguminosae) plant family contains several species of the Mucuna Adans. genus possessing therapeutic potential and growing widely in tropical and sub-tropical regions. In this research, we investigated the anti-inflammatory and antioxidant properties of the extract from the Mucuna sanjappae Aitawade & S.R.Yadav seeds. Initially, we conducted an in vitro anti-inflammatory activity test using the bovine serum albumin anti-denaturation assay and found promising dose-dependent activity. Subsequently, we performed an in vivo anti-inflammatory and antioxidant study on a rat paw edema model induced by carrageenan. Three different doses of M. sanjappae seed water extract (50, 100 and 200mg/kg B/W) were used for the study (Oral administration). Edema measurement was carried out at 0, 2, 4 and 6 hr intervals. Dose dependent inhibition in edema in the M. sanjappae seed extract treatment group was observed with maximum activity for 200mg/kg B/W dose at 4 hr (53.49%). Standard drug showed maximum edema inhibition (54.94%) at 6hr. Our results also showed that, M. sanjappae seed extract inhibited pro-inflammatory cytokine TNF-α and increases anti-inflammatory cytokine IL-10 with increased level of blood serum antioxidants. Phytochemical analysis for secondary metabolites including polyphenol, flavonoids, phytic acid, proanthocyanidin, tannin and saponin was also quantified which might be the responsible component for biological activities under study.

In recent years, there has been a growing interest in the use of medicinal plants and phytochemicals as potential treatments for acne vulgaris. This condition, characterized by chronic inflammation, predominantly affects adolescents and young adults. Conventional treatment typically targets the key factors contributing to its development: the proliferation of Cutibacterium acnes and the associated inflammation. However, these treatments often involve the use of potent drugs. As a result, the exploration of herbal medicine as a complementary approach has emerged as a promising strategy. By harnessing the therapeutic properties of medicinal plants and phytochemicals, it may be possible to address acne vulgaris while minimizing the reliance on strong drugs. This approach not only offers potential benefits for individuals seeking alternative treatments but also underscores the importance of natural remedies of plant origin in dermatological care. The primary aim of this study was to assess the antimicrobial, antioxidant, and anti-inflammatory properties of plants and their phytochemical constituents in the management of mild acne vulgaris. A comprehensive search of scientific databases was conducted from 2018 to September 2023. The findings of this review suggest that medicinal plants and their phytochemical components hold promise as treatments for mild acne vulgaris. However, it is crucial to note that further research employing high-quality evidence and standardized methodologies is essential to substantiate their efficacy and safety profiles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
