    Studies on the Constituents of Schisandra Henryi Ⅴ. The Structures of Wulignan A1, A2, Epiwulignan A1 and Epischisandrone)[Reference: WebLink]

    METHODS AND RESULTS:
    Four new lignan compounds named Wulignan A1 (4), A_2(5), epiWulignan A1 (6) and epischisandrone(7), and three known lignan compounds, enshicine(1), epienshicine(2) and schisandrone(3), were isolated from the fruits of Schisandra henryi Clarke collected in the district of Yibin, Sichuan Province.
    CONCLUSIONS:
    In anticancer screening all the four new compounds exhibit the activity against leukemia P-388 in vitro. Wulignan A1(4),

    Schisandrae fructus extracts for inhibition or prevention of H1N1 influenza virus infection and its application thereof[Reference: WebLink]
    Disclosed are an Schisandrae fructus extract for inhibition or prevention of influenza and its application, wherein the Schisandrae fructus extract is obtained by water, methanol, or ethanol extraction process and the extract comprises compounds such as schisandrone, benzoylgomisin P, Wulignan A1, epigomisin O, epiWulignan A1, and tigloylgomisin P. The extracts and purified compounds of Schisandrae fructus has anti-influenza virus H1N1 and H1N1-TR (a Tamiflu drug resistant virus strain) activities, therefore the extracts and the purified compounds of Schisandrae fructus can be applied as an inhitibory agent of a pharmaceutical composition for treatment or prevention agent for influenza infection.

    Two new lignans from Schisandra henryi.[Pubmed: 19336937]

    METHODS AND RESULTS:
    Two new lignans, henricines A (1) and B (2), were isolated along with the eight known lignans, ganshisandrine (3), wulignan A2 (4), epiwulignan A(1) (5), deoxyschisandrin (6), Wulignan A1 (7), epischisandrone (8), schisantherin A (9), and schisandrol A (10), from the stems of Schisandra henryi.
    CONCLUSIONS:
    The structures of the new compounds were elucidated based on the spectral analysis, including 1D and 2D NMR experiments.
