[Study on the chemical constituents of the fruit handles from Schizandra chinensis].

Objective: To study the chemical constituents of the fruit handles from Schizandra chinensis.

Methods: Compounds from the 85% ethanol extracts were isolated by silica gel, Sephadex LH-20, recrystal, etc., and their structures were identified by the spectral analysis and chemical evidence.

Results: Eight compounds were isolated and identified as wuweizisu C (I), ganwuweizic acid(II), beta-sitosterol(III), gomisin A(IV), schizandrin(V), daucosterol(VI), wuweizisu A(VII), gamma-schizandrin (VIII).

Conclusion: Compounds I - VIII are isolated from the fruit handles of Schizandra chinensis for the first time.
