摘要: 本实验是对多裂山莴苣Lactuca laciniata根茎中的化学成分进行研究,通过利用柱色谱对植物中的成分进行分离纯化,并利用现代波谱方法确定化合物的结构。结果从该植物中共分离出12个化合物,分别鉴定为(2S)-1-O-heptatriacontanoyl glycerol(1)、(2S,3S,4R,10E)-2-[(2R)-2-羟基二十四烷酰氨基]-10-十八烷-1,3,4-三醇(2),11β,13-二氢莴苣内酯乙酸酯(3),lactucin(4)、莴苣苷B(lactuside B,5)、lactucopicrin(6)、齐墩果酸(7)、十六烷酸(8)、槲皮素(9)、木栓酮(10)、熊果酸(11)、辛二酸(12),化合物1、2、4、6~12是首次从该植物中分离得到,化合物1、12为首次从该属植物中分离得到。

Abstract: The experiment is to investigate the chemical constituents in rhizome of Lactuca laciniata. 12 compounds were separated by silica gel column chromatography and their structures were determined by spectroscopic experiments.They were identified as (2S)-1-O-heptatriacontanoyl glycerol (1), (2S,3S,4R,10E)-2-[(2R)-2-hydroxyl tetracosanoylamino]-10- octadecene-1,3,4-triol (2), 11β,13-dihydrolactucin acetate (3), lactucin (4), lactuside B (5), lactucopicrin (6), oleanolic acid (7), hexadecanoic acid (8), quercetin (9), friedelin (10), ursolic acid (11), octanedioic acid (12). Compounds 1,2,4,6-12 are separated from this plant for the first time and compounds 1 and 12 are isolated from the genus for the first time.

Key words: Lactuca laciniata, Compositae, 11&beta, ,13-dihydrolactucin acetate, lactuside B, quercetin
