Phytochemical Profiling and Biological Activity of the Australian Carnivorous Plant, <i>Drosera magna</i>

Phytochemical profiling was undertaken on the crude extracts of Drosera magna to determine nature chemical constituents present. In total, three new flavonol diglycosides (1–3), one flavan-3-ol glycoside (4), and 12 previously reported compounds (5, 9), (15), flavanone (8), 1,4-napthoquinone (6, 7, 13, 14), 2,3-dehydroxynapthalene-1,4-dione (10–12), phenolic acid (16) structure classes were isolated identified. Compounds 1–9, 17, 18 assessed for antimicrobial activity, with 6, 8, 9 showing significant activity. 1, 2, 6 also evaluated anthelmintic activity against larval forms Hemonchus contortus, compound being active.
