摘要 研究雷公藤(TripterygiumwilfordiiHook.f.)根心部分的化学成分,采用硅胶柱色谱法进行分离,从其氯仿提取物中分到两个神经酰胺类化合物的混合物,并运用现代波谱技术和化学方法鉴定了化合物的结构,经鉴定化合物结构分别为:N-(2'-羟基二十四碳酰基)-1,3,4-三羟基-2-氨基-十八烷(1),N-(2'-羟基二十五碳酰基)-1,3,4-三羟基-2-氨基-Δ8,9(E)-十八碳烯(2).化合物(1),(2)为首次从雷公藤中分离得到. <Abstrcat> The mixture of two ceramides were isolated by various column chromatographies with silica gel from Tripterygium wilfordii Hook. f.. Their structures were identified as (2S, 3S, 4R)-2--1,3,4-octadecanetriol (1), (2S, 3S, 4R, 8E)-2--8-octadecene-1, 3, 4-triol (2). Compound (1), (2) was isolated from this plant for the first time.
