摘 要:目的:研究苦绳Dregea sinensis var.corrugata的化学成分。方法:采用硅胶、凝胶等色谱技术进行分离,通过NMR等波谱学方法确定化合物的结构。结果:分离并鉴定了8个化合物,分别为丁香脂素(1),松脂素(2),syringaresinol-4′-O-β-D-glucoside(3),3,4′二甲氧基-4,9,9′-三羟基-苯并呋喃木脂素-7′-烯(4),coniferaldehyde(5),sinapic aldehyde(6),松柏素(7),3-hydroxy-1-(3-methoxy-4-hydroxyphenyl)-propan-1-one(8)。结论:化合物1—8均为首次从该植物中分离得到。Objective: To study the chemical constituents ofDregea sinensis vat. 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-β-D-glycopyranoside (2), 3, 4′- dimethoxyl-4, 9, 9′-trihydroxyl-benzofuranneolignan-7′-ene (3), 3, 4′-di- methoxyl-4, 9-dihydroxyl-9′-hydroethyl-benzofuranneolig- nan-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 vat. corrugata for the first time.
