【摘要】 目的 对白花泡桐叶的化学成分进行研究。方法 采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱、半制备液相色谱等多种色谱方法进行分离纯化，并结合理化性质及波谱解析等方法进行结构鉴定。结果与结论从白花泡桐叶中分离得到13个化合物，分别为3β-hydroxy-oleana-11,13(18)-dien-28-oic acid(1)、3β,28-dihydroxyoleana-11,13(18)-diene(2)、3-epiursolic acid(3)、eupatoric acid(4)、ursaldehyde(5)、熊果酸(6)、euscaphic acid(7)、3β-hydroxy-18α,19α-urs-20-en-28-oic acid(8)、2α,3β-dihydroxylup-12-en-28-oic acid(9)、phytol(10)、角鲨烯(11)、3-hydroxy-4-methoxypyridine(12)、pheophytin A(13)。其中，化合物1、4、5、8、9、12、13为首次从泡桐属中分离得到，化合物7、10、11为首次从白花泡桐中分离得到。更多还原

【Abstract】 In order to study the chemical compositions of the leaves of Paulownia fortune(Seem.) Hemsl.,thirteen compounds were isolated by silica gel column chromatography, Sephadex LH-20 gel column chromatography, semi preparative liquid chromatography.These compounds were identified by their physicochemical properties and spectral data, as 3β-hydroxy-oleana-11,13(18)-dien-28-oic acid(1),3β,28-dihydroxyoleana-11,13(18)-diene(2),3-epiursolic acid(3),eupatoric acid(4),ursaldehyde(5),ursolic acid(6),euscaphic acid(7),3β-hydroxy-18α,19α-urs-20-en-28-oic acid(8),2α,3β-dihydroxylup-12-en-28-oic acid(9),phytol(10),squalene(11),3-hydroxy-4-methoxypyridine(12) and pheophytin A(13).Compounds 1,4,5,8,9,12 and 13 were isolated from Paulownia.for the first time, and compounds 7,10 and 11 were isolated from Paulownia fortune(Seem.) Hemsl. for the first time.更多还原
