从毒胡萝卜Thapsia garganica L.中分离出的具有刺激皮肤和促肿瘤生长作用的倍半萜烯内酯毒胡萝卜精(thapsigaugin)及毒胡萝卜辛(thapsigargicin)导致了对这些内酯的生物化学和毒胡萝卜属植物化学的深入研究。本文报道了一种新的五氧化的愈创内酯的分离和组胺释放的特性。除早先鉴定的天然产物之外,又从毒胡萝卜果实的乙醇提取物中离到一种新的倍半萜烯内酯。~1HNMR谱表明,除了以丁 The sesquiterpene lactone thapsigaugin and thapsigargicin isolated from the poisonous carrot Thapsia garganica L. have stimulative skin and promote tumor growth, resulting in the biochemistry and toxicity of these lactones. An in-depth study of the chemistry of carrots. This paper reports on the isolation and histamine release characteristics of a novel pentavalent flavonoid. In addition to the previously identified natural products, a new sesquiterpene lactone was isolated from the ethanol extract of Poisonous Carrot fruits. ~1H NMR spectrum shows that except for D
