摘要: 目的 研究白蔹的化学成分。 方法 利用各种色谱法进行分离,根据理化性质和波谱分析鉴定化合物结构。 结果 从白蔹的氯仿和乙酸乙酯萃取部分又分离得到7个已知成分,分别鉴定为甲基-α-D-呋喃果糖苷(1)、甲基-β-D-吡喃果糖苷(2)、β-D-呋喃果糖甲苷(3)、β-D-呋喃果糖(4)、尿苷(5)、腺苷(6)、大黄素-8-O-β-D-吡喃葡萄糖苷(7)。 结论 化合物1、2、3、4、5、6为首次从该植物中分离得到。Abstract: Objective To isolate and identify the compounds from the Ampelopsis japonica(Thunb.) Makino. Methods The compounds were separated and purified by column chromatography and their structures were established by spectroscopic methods. Results Seven compounds were obtained from the chloroform and ethyl acetate extracts of the Ampelopsis japonica(Thunb.) Makino which were determined as Methyl-α-D-frucofuranoside (1), Methyl-β-D-frucofuranoside (2), Methyl-β-D-frucopyranoside (3),Methyl-β-D-frucofuranose(4),Uridine(5),Adenosine(6),Emodin-8-O-β-D-glucopyranoside (7). Conclusion Compounds 1,2,3,4,5,6 were isolated from the Ampelopsis japonica(Thunb.) Makino for the first time.
