[Studies on the chemical constituents of Schisandra pubescens]

Abstract

Objective: To study the chemical constituents of Schisandra pubescens.

Methods: The chemical constituents were isolated by silica gel, Prep-HPLC and Prep-TLC methods. And their structures were elucidated by physical-chemical and spectroscopic methods.

Results: Seven compounds were obtained and identified as (+)-gomisin K2 (I), gomisin S (II), Pregomisin (III), Schisantherin A (IV), Schicantherin B (V), Angeloylgomisin Q (VI), Rubrildilactione (VII).

Conclusion: All compounds are isolated from this plant for the first time.
