摘要
从清香木姜子(Litsea euosmaW.W.Smith)的枝叶中分离得到1个新化合物—α-吡喃酮衍生物(1)以及3个已知化合物阿魏酸酯衍生物(2),6-氧-棕榈酰-β-胡萝卜甙(3)和葡萄糖(4)。经波谱学鉴定新化合物α-吡喃酮衍生物的结构为5-羟基-6-甲基-3-(10-十一烯基)-5,6-二氢吡喃-2-酮。
Chemical investigation on the leaves and twigs of Litsea euosma W. W. Smith (Lauraeeae) led to the isolation of a new compound named a derivative of α-pyranone ( 1 ) together with three known compounds, a derivative of ferulic acidic ester (2), 6- O-palmitoyl-β-sitosteryl-D-glucoside (3) and glucose (4). The structure of the new compound is elucidated as 5-hydroxy-6-methyl-3 -( undec-10-enyl )-5, 6-dihydropyran-2-one based on its spectroscopic analysis.
