Abstract

Sixteen daphnane Diterpenoids, trigothysoids A-P, along with 15 known ones, were isolated from the methanol extract of the twigs and leaves of Trigonostemon thyrsoideum. Their structures were established by extensive spectroscopic techniques, including 2D NMR spectroscopy and mass spectrometry. The anti-HIV-1 activity of the compounds was also evaluated in vitro, and five compounds demonstrated potent anti-HIV-1 activity, with EC50 values of 0.015-0.001 nM and TI values of 1618-17,619.
