7,8-secolignans from Schisandra neglecta and their anti-HIV-1 activities

[摘要] Four new 7,8-secolignans (neglectahenols A-D), together with two known 7,8-secolignans, were isolated from leaves and stems of Schisandra neglecta. The structures were elucidated by spectroscopic methods, including extensive one and two dimension NMR (nuclear magnetic resonance) techniques. 7,8-Secolignans and neglectahenols A-D were also tested for their anti-HIV-1 (human immunodeficiency virus type 1) activities, and all of them showed modest activities.
