Zhongguo yao xue za zhi,2005,40(5):337-341. | Studies on the liposoluble components from tuber of Ophiopogon japonicus.[Reference: WebLink] | METHODS AND RESULTS: The compounds were isolated by column chromatography with silica gel and Sephadex LH-20 and the structures were elucidated by spectras' analysis. Sixteen compounds were obtained as 7 homoisoflavones, 2 anthraquinones, 3 phenolic acids, 2 terpenes and 2 fatty acids. Their structures were identified as methylophiopogonanone A(I), methylophiopogonanone B(II), methylophiopogonone A(III), Methylophiopogonone B(IV), 2'-hydroxy-methylophiopogonone A(V), 6-aldehycto-isoophiopogo-nanone A(VI), 5,7-dihyelroxy-8-methoxy-6-methyl-3-(2'-hydroxy-4'-methoxybenzyl) chroman-4-one(VII), chrysophenol(VIII), emodin(IX), vanillic acid(X), P-hydroxy benzaldenhyde (XI), P-trans-coumarinic acid(XII), l-borneol-#beta#-D-glucopyranoside (XIII), oleanolia acid(XIV), azelaic acid (XV) and n-tricosanoic acid(XVI).
CONCLUSIONS:
The compound IV, VIII--XII and XIV--XVI were isolated from O. japonicus and the genus Ophiopogon for the first time, respectively. The types of anthraquinone, phenolic acid and triterpene were firstly obtained from the genus. |
