Phytochemical Profiling and Biological Activity of the Australian Carnivorous Plant,Drosera magna

Abstract

Phytochemical profiling was undertaken on the crude extracts ofDrosera magnato determine the nature of the chemical constituents present. In total, three new flavonol diglycosides (1-3), one new flavan-3-ol glycoside (4), and 12 previously reported compounds of the flavonol (59), flavan-3-ol (15), flavanone (8), 1,4-napthoquinone (671314), 2,3-dehydroxynapthalene-1,4-dione (10-12), and phenolic acid (16) structure classes were isolated and identified. Compounds1-91317, and18were assessed for antimicrobial activity, with compounds678, and9showing significant activity. Compounds12, and6were also evaluated for anthelmintic activity against larval forms ofHemonchus contortus, with compound6being..
