The Genus Gnaphalium L. (Compositae): Phytochemical and Pharmacological Characteristics

et al. 2013

View full text Add to dashboard Cite

Abstract:The genus Gnaphalium, a herb distributed worldwide, comprises approximately 200 species of the Compositae (Asteraceae) family that belongs to the tribe Gnaphalieae. Some species are traditionally used as wild vegetables and in folk medicine. This review focuses on the phytochemical investigations and biological studies of plants from the genus Gnaphalium over the past few decades. More than 125 chemical constituents have been isolated from the genus Gnaphalium, including flavonoids, sesquiterpenes, diterpenes, triterpenes, phytosterols, anthraquinones, caffeoylquinic acid derivatives, and other compounds. The extracts of this genus, as well as compounds isolated from it, have been demonstrated to possess multiple pharmacological activities such as antioxidant, antibacterial and antifungal, anti-complement, antitussive and expectorant, insect antifeedant, cytotoxic, anti-inflammatory, antidiabetic and antihypouricemic properties. The present review compiles the information available on this genus because of its relevance to food and ethnopharmacology and the potential therapeutic uses of these species.

Dasymaschalolactams A–E, Aristolactams from a Twig Extract of Dasymaschalon dasymaschalum

et al. 2019

View full text Add to dashboard Cite

Five new aristolactam alkaloids (1−5), dasymaschalolactams A−E, and the first isolation of dasymaschalolactone (17) as a natural product, together with 19 known compounds (6−16 and 18−25) were isolated from the twig extract of Dasymaschalon dasymaschalum. Their structures were elucidated by spectroscopic methods as well as comparisons made from the literature. Compounds 20 and 21 showed α-glucosidase inhibitory activities with IC 50 values of 4.5 and 24.7 μM, respectively.
