目的研究三白草Saururus chinensis全草的化学成分。方法采用多种柱色谱法分离,通过理化鉴别及波谱分析技术鉴定化合物的结构。结果从三白草全草95%乙醇提取物中分离得到了7个化合物,分别鉴定为反式-7,8-二氢-7-(3,4-亚甲二氧基)苯基-1′-(2-氧丙基)-3′-甲氧基-8-甲基苯并呋喃(1)、4-(3-甲氧基-4-羟基)苯基-3-甲基-3-丁烯-2-酮(2)、(+)-愈创木素(3)、(+)-反式-1,2-二氢脱氢愈创木脂酸(4)、异落叶松脂素-4-O-β-D-葡萄糖苷(5)、异甘密树脂B(6)和perseal F(7)。结论化合物1为新化合物,命名为三白脂B,化合物2~7均为首次从该植物中分离得到。
Objective To study the chemical constituents of whole plant Saururus chinensis. Methods Various column chromatographic methods were used to identify the structures of compounds by physical and chemical identification and spectroscopic analysis. Results Seven compounds were isolated from the 95% ethanol extract of the whole plant, and were identified as trans-7,8-dihydro-7- (3,4-methylenedioxy) phenyl- ’- (2-oxopropyl) -3’-methoxy-8-methylbenzofuran (1) (2), (+) - guaulisin (3), (+) - trans-1,2-dihydrodehydrogalacturonic acid (4) 4-O-β-D-glucoside (5), allomix resin B (6) and perseal F (7). Conclusion Compound 1 is a new compound named tricaprole B, and compounds 2 ~ 7 were isolated from this plant for the first time.
