Isolation and Bioactivities of Stemona Alkaloid: A Review

Objective/Background: In Chinese, Vietnamese, and Thai traditional medicine of Southeast Asian countries, Stemonaceae plants have long been employed. Various studies have proved that these herbal plants contain Stemona alkaloids with valuable medicinal value. Although some review articles on Stemona alkaloids have appeared in the literature, they are quite outdated. The current study offers a comprehensive review of the isolation and bioactivities of Stemona alkaloids. The article might be useful for chemists who work in alkaloid chemistry as well as pharmaceutical areas. Methods: “ Stemona alkaloids” was the most useful keyword to search for literature data. References have been collected from various resources such as Google Scholar, SciFinder, and PubMed. More than 120 electronic publications were obtained from these resources. Results: More than 250 Stemona alkaloids from 8 groups have been isolated and structurally elucidated from Stemonaceae plants. Extracts from these plants as well as isolated compounds possess a wide range of bioactivities, such as antituberculosis, antibacterial, antifungal, and antihelmintic properties activities. Conclusion: In this review article, we have summarized 116 studies on the isolation and bioactivities of Stemona alkaloids in the literature. More than 250 Stemona alkaloid compounds have been isolated and identified. In addition, the article also gives an overview of the bioactivities of Stemona alkaloids.
