Twelve known compounds were isolated from the whole plant of Incarvillea delavayi.Based on MS and NMR analysis,these compounds were determined as tecomine (1),epidihydrotecomanine (2),2,6-dimethyl-6-hydroxy-2-heptene-4-one (3),marine B (4),(3R,5 S)-3-methyl-cyclopentyl [1,2-c] pyridine-5-ol (5),Ethyl 3,4,5-trimethoxy-benzoate (6),cleroindicin B (7),3,4,5-trimethoxy-benzoic acid methyl ester (8),2-(4-ethoxy-phenyl)-ethanol (9),2,3-dihydro-benzofuran-6-ol (10),β-sitoserone (11) and β-acetyloleanolic acid (12).Among them,compounds 1-3,5-6,8-12 were isolated from the genus Incarvillea for the first time,and all compounds were isolated from the species for the first time.%从红波罗花(Incarvillea delavayi)植物的干燥全草乙醇提取物中分离得到12个化合物,通过MS和NMR等方法鉴定为tecomine (1)、epidihydrotecomanine (2)、2,6-二甲基-6-羟基-2-庚烯-4-酮(3)、marine B(4)、(3R,5S)-3-methyl-cyclopentyl[1,2-c] pyridine-5-ol (5)、3,4,5-三甲氧基苯甲酸乙酯(6)、cleroindicin B(7)、3,4,5-三甲氧基苯甲酸甲酯(8)、2-(4'-乙氧基苯基)-乙醇(9)、6-羟基苯并二氢呋喃(10)、β-谷甾酮(11)、β-乙酰齐墩果酸(12).其中化合物1～3、5～6、8～12为首次从角蒿属植物中分离得到,所有化合物均为首次从该植物中分离得到.
