A relatively large quantity of the plant material (3.6 kg) was then re-collected from the same tree to carry out bioassayguided fractionation in order to isolate the anti-HIV active compounds.
Accordingly, 13 compounds were isolated and identified including one new lignan (1), under bioassay-guided phytochemical separation.
The current paper describes the isolation, identification, structure elucidation, and biological evaluation of these isolates from this species.
