Zhongguo Zhong Yao Za Zhi. 2008 Dec; 33(23): 2787-9Chen XH, Liu YB, Yu SS, Qu J, Hua HMOBJECTIVE: To study the chemical constituents of Dregea sinensis var. corrugata. METHOD: The chemical constituents were isolated by various column chromatographic techniques. Structures were elucidated on the basis of NMR data. RESULT: Eight compounds were isolated and their structures were elucidated as syringaresinol (1), syringaresinol-O-3-D-glycopyranoside (2), 3, 4'-dimethoxyl-4, 9, 9'-trihydroxyl-benzofuranneolignan-7'-ene (3), 3, 4'-di- methoxyl-4, 9-dihydroxyl-9'-hydroethyl-benzofuranneolignan-7'-ene (4), conifer-aldehyde (5), sinapic aldehyde (6), 3-hydoxy-1-(4-hydroxy-3-methoxy-phenyl)-propan-1-one (7), 3-hydroxy-1-(3-methoxy-4-hydroxyphenyl)-propan-1-one (8). CONCLUSION: Compounds 1-8 were isolated from Dregea sinensis var. corrugata for the first time.
