目的:研究淡黄香茶菜Rabdosia flavida(Hand.-Mazz.)Hara根茎的化学成分。方法:采用多种柱色谱法进行化学成分分离与纯化,通过现代波谱分析及理化性质等手段对分离得到的化合物进行结构解析。结果:从淡黄香茶菜根茎70%丙酮提取物的乙酸乙酯部位分离得到10个化合物,分别鉴定为:弥罗松酚(1)、脱氢木香内酯(2)、蒲公英甾醇(3)、油酸(4)、乌苏酸(5)、松柏醛(6)、齐墩果酸(7)、6,12,15-三羟基-5,8,11,13-松香四烯-7-酮(8)、5α,8α-环二氧麦角甾-6,22-二烯-3β-醇(9)、胡萝卜苷(10)。结论:化合物1~10均为首次从淡黄香茶菜中分离得到。
Objective: To study the chemical constituents of rhizomes of Rabdosia flavida (Hand.-Mazz.) Hara. Methods: The chemical constituents were isolated and purified by a variety of column chromatography. The structure of the isolated compounds was analyzed by modern spectroscopic analysis and physicochemical properties. Results: Ten compounds were isolated from the ethyl acetate fraction of 70% acetone extract from the root of Camellia oleifera, and were identified as: poloxamer (1), dehydrocostus (2), dandelion sterol (3) Oleic acid (4), ursolic acid (5), coniferyl aldehyde (6), oleanolic acid (7), 6,12,15-trihydroxy-5,8,11,13-rosin-4 -ketone (8), 5a, 8a-cycloterivir-6,22-dien-3β-ol (9), daucosterol (10). Conclusion: Compounds 1 ~ 10 were isolated from the light yellow tea for the first time.
