[Study on chemical constituents from Schisandra chinensis stem]
Objective:
To separate and identify the chemical constituents from the stem of Schisandra chinensis.
Methods:
Various chromatographic techniques were used to separate and purify the chemical constituents from 95% ethanol extraction of the stem of Schisandra chinensis. Their structures were elucidated based on the physico-chemical properties and spectral data.
Results:
Ten compounds were obtained and elucidated as (+)-deoxyschizandrin (1), γ-schizandrin (2), wuweizisu C (3), gomisin N (4), schizandrin (5), anwuweizic acid (6), (-)-dihydroguaiaretic acid (7), tetradecanoic acid (8), β-sitosterol (9) and daucosterol (10).
Conclusion:
Compounds 6-8 are obtained from the stem of Schisandra chinensis for the first time.
