【摘要】 从虎眼万年青 (Ornithogalum caudatum) 的球茎中,用色谱方法分离得到1个新天然产物1和26个已知化合物2~27,它们的结构经波谱法和化学方法确定为n-butyl pyroglumate(1), 十九醇(2), 二十醇(3), 二十二烷酸(4),b-谷甾醇(5),豆甾醇(6),二十六烷酸1-甘油酯(7),儿茶酚(8),对乙氧基苯甲酸(9),p-香豆酸 (10),原儿茶酸(11),熊果酸(12),白桦脂酸(13),富马酸(14),琥珀酸(15),尿嘧啶(16),黄嘌呤(17),槲皮素(18),山柰酚(19),异鼠李素(20),腺嘌呤核苷(21),胡萝卜甙(22),豆甾醇3-O-b-D-葡萄糖甙(23),槲皮素3-O-b-D-葡萄糖甙(24),山柰酚3-O-b-D-葡萄糖甙(25),芦丁(26),山柰酚3-O-b-芸香糖甙(27)。其中除化合物5外,其它成分均首次从虎眼万年青属植物中分离得到。更多还原

【Abstract】 A new natural product (1) together with 26 know compounds were isolated from the Bulbs of Ornithogalum caudatum. Their structures were established on the basis of spectral analyses as n-butyl pyroglutamate (1), nonadecyl alcohol(2), eicosanol(3), behenic acid(4), b-sitosterol(5), stigmasterol(6), glycerol 1-monocerotate(7), pyrocatechol(8), p-ethoxybenzoic acid(9), p-coumarinic acid(10), protocatechuric acid(11), ursolic acid(12), betulinic acid(13), fumaric acid(14), succinic acid(15), uracil(16), xanthine(17), quercetin(18), kaempferol (19), isorham-netin(20), adenosine(21), daucosterol(22), stigmasterol 3-O-b-D-glucopyranoside(23), quercetin 3-O-b-D-glucopyra-noside(24), kaempferol 3-O-b-D-glucopyranoside(25), rutin(26), and kaempferol 3-O-b-rutinoside(27). All of them, except compound 5, were isolated from this plant for the first time.更多还原
