[Chemical constituents from supercritical CO2 extraction of Schisandra chinensis].

Objective: To study the chemical constituents from the supercritical CO2 extraction of Schisandra chinensis.

Methods: The compounds were separated and purified by conventional column chromatography and their structures were identified by spectroscopic methods.

Results: Nine compounds were isolated from the supercritical CO2 extraction of Schisandra chinensis, and their structures were identified as chrysophanol(1),schisandrin B(2), β-sitosterol(3), schisandrin C(4),schisandrol A(5), angeloylgomisin H(6), daucosterol(7) 1, 5-dimethyl citrate (8), and shikimic acid (9).

Conclusion: Compounds 1, 8 and 9 are isolated from Schisandra chinensis for the first time,and compound 1 as an anthraquinone is isolated from this genus for the first time.
