利用多种色谱技术对藏药双花千里光Senecio dianthus地上部分95%乙醇浸提物进行分离纯化,共得到5个化合物,根据理化数据和波谱数据鉴定化合物的结构分别为:艾里莫芬-9(10),7(11)-二烯-8-酮-12-羧酸-β-D-吡喃葡萄糖苷,命名为双花千里光苷A(1),5,7,4’-三羟基-黄酮-3-O-β-D-葡萄糖苷(2),槲皮素-3-O-β-D-葡萄糖苷(3),金丝桃苷(4),芦丁(5)。其中,化合物1为新化合物,化合物2,4,5均为首次从双花千里光中分离得到。
A total of five compounds were isolated and purified from 95% ethanolic extracts of Senecio dianthus by HPLC using various chromatographic techniques. The structures of the compounds were identified according to physicochemical and spectroscopic data as follows: 9 (10), 7 (11) -dien-8-one-12-carboxylic acid-β-D-glucopyranoside, (2), quercetin -3-O-β-D-glucoside (3), hyperin (4), rutin (5) . Among them, compound 1 was a new compound, and compounds 2, 4 and 5 were isolated from Senecio for the first time.
