gamma-sitosterol and schizandrin

To separate and identify the chemical constituents from the stem of Schisandra chinensis.. 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.. 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).. Compounds 6-8 are obtained from the stem of Schisandra chinensis for the first time.

To study the chemical constituents from the supercritical CO2 extraction of Schisandra chinensis.. The compounds were separated and purified by conventional column chromatography and their structures were identified by spectroscopic methods.. 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).. 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.

To study the chemical constituents of vinegar Schisandra chinensis.. Column chromatography was used in the isolation procedure. The structures of isolated compounds were elucidated by spectral data.. Five compounds were isolated and their structures were identified as kadsuranin (I), beta-sitosterol (II), schizandrin (III), 5,5'-[oxybis (methylene)] bis-2-furancarboxaldehyde (IV) and (NH)-form-2-Hydroxyquinoline4-carboxylic acid (V).. Compound 5 is isolated from this genus for the first time.
