Mahamanalactone A, a new triterpenoid from Dysoxylum malabaricum bark: a case study for rapid identification of new metabolites via LC-HRMS profiling and database mining strategy.

In this recent investigation, the focus centred on exploring the potential phytoconstituents within the bark of Dysoxylum malabaricum. A profiling strategy employing LC-HRMS (Liquid Chromatography-High Resolution Mass Spectrometry) was implemented for the rapid identification of compounds from the bark extract. The crude extract underwent fractionation, resulting in the isolation of four previously known compounds (1-4) and a novel cycloartane triterpenoid named Mahamanalactone A (5). Compound 5 represents a cycloartane triterpenoid with a modified ring-A, featuring £-caprolactone fusion at positions 4 and 5, distinguishing it from other reported compounds where £-caprolactone is typically fused at positions 3 and 4. Cytotoxicity assessment revealed that the newly identified compound 5 exhibited a moderate cytotoxic profile (IC50 29 to 78 µM) against a panel of cancer cell lines.

A comprehensive review on Saraca asoca (Fabaceae) - Historical perspective, traditional uses, biological activities, and conservation.

ETHNOPHARMACOLOGICAL RELEVANCE: Saraca asoca (Roxb.)W.J.de Wilde, (Fabaceae) is a plant of significant medicinal value in traditional Indian medicine, with a long history of use in the treatment of gynaecological disorders and other ailments, and is held in high esteem. This plant has long existed in Indian tradition and is revered as sacred. AIM OF THE STUDY: This work aimed to explore the taxonomic revision of Saraca asoca from ancient times to the present and to evaluate the ethnobotanical, phytochemical and pharmacological information associated with traditional use and develop a roadmap for conservative strategies of species. MATERIALS AND METHODS: The study draws on a comprehensive range of herbal, traditional, ethnobotanical, and ethnopharmacological information, including ancient Ayurvedic textbooks and various databases, using a single keyword or a combination of multiple keywords. RESULTS: This review establishes a roadmap for understanding the traditional history of medicinal plants, particularly Saraca, and highlights the transfer of traditional knowledge from pharmacopoeias, materia medica, and classical textbooks over many centuries. The study also emphasises the importance of conservation strategies to protect Saraca as a valuable resource for healthcare and suggests that more research is needed to systematically evaluate its phytochemical, pharmacological, and clinical properties, as well as to develop safety, pharmacology, and toxicology reports for traditional formulations. CONCLUSIONS: In light of this study, S. asoca could be considered an important source of potential herbal drugs. The review concludes with a call for further research and conservation efforts to protect Saraca and other traditional medicinal plants for the benefit of current and future generations.
