羊红膻根化学成分的研究Ⅲ.羊红膻素F的分离和鉴定

Studies on the Chemical Constituents of the Root of Thellung Pimpinella (Pimpinella thellungiana) (Ⅲ):Separation and Identification of Thellungianin F

从草药羊红膻根中又分得2个化合物，经光谱解析（UV，IR，1H、13CNMR，DEPT及1H-1HCOSY，1H－13CCOSY），确定这2个化合物的结构为：4-羟基-丙烯苯-（2-甲基丁酸）酯（Ⅰ），2-羟基-5-甲氧基-丙烯苯-（2-甲基丁酸）酯（Ⅱ）。Ⅰ为新化合物，定名为羊红膻素F。Ⅱ为首次从本植物中分得。

Two compounds were isolated from the root of Pimpinella thellungiana Wolff.. On the basis of spectral analysis (UV,IR, 1HNMR, 13CNMR, DEPT, 1H-1H COSY, 1H-13C COSY),they were identified as 4-propenyl-phenyl-2-methyl butanoate(Ⅰ) and 4-methoxy-1-propenyl-phenyl-2-me butanoate(Ⅱ). Ⅰ is a new compound named thellungianin F. Ⅱ was obtained from this plant for the first time.
