Chapter 1. Investigation on Chemical Constituents and Bioactivivities of

Schisandra lancifolia Schisandra lancifolia (Rehd. et Wils.) A. C. Smith, a member of Schisandraceae family, was used in Chinese traditional medicine to staunch, to treat fractures and eliminating stasis to reduce swelling. In our present study, 38 compounds were isolated and identified including 11 new compounds. Among them, compound 1 was a novel triterpene derivative featured an unprecedented rearranged pentanortriterpenoid backbone derived from cycloartane and compound 2, possessed a highly oxidized norcycloartane skeleton and characterized with an enol-form structure part and a spirocyclic moiety in its structure. Some compounds were tested for their anti-HIV-1 activity and six of them show anti-HIV-1 activity with SI values more than 10.
