Title: [Sesquiterpenes from stem of Schisandra glaucescens]. Author: Zhang PP, Gao SS, Zhang TT, Chen JC, Duan HQ, Fang JB. Journal: Zhongguo Zhong Yao Za Zhi; 2012 Nov; 37(22):3426-9. PubMed ID: 23373215. Abstract: OBJECTIVE: To study the chemical constituents from Schisandra glaucescens. METHOD: The chemical constituents were separated and purifed with silica gel, gel column chromatography preparative HPLC, and their structures were identified by such spectral methods as MS and NMR. RESULT: Twelve compounds were separated from petroleum ether fractions, and identified as t-cadinol (1), alpha-cadinol (2), torreyol (3), (+)-ent-epicubenol (4), ent-T-muurolol (5), (-)-15-hydroxycalamenene (6), (-)-cubebol (7), 4-epi-cubebol (8), caryophyllenol-I (9), caryophyllenol-II (10), oxyphyllenodiols A (11), caryolane-1,9/3-diol (12). CONCLUSION: Compounds 4, 6-12 were separated from the genus for the first time, while compounds 1-12 were separated from this plant for the first time.[Abstract] [Full Text] [Related] [New Search]
