目的研究南刘寄奴中的黄酮类成分。方法运用各种柱色谱法分离,采用核磁共振波谱技术和理化性质鉴定化合物的结构。结果共分离得到了11个黄酮类化合物,分别鉴定为:异鼠李素(1)、山柰酚(2)、半齿泽兰素(3)、木犀草素(4)、芹菜素(5)、槲皮素(6)、大波斯菊苷(7)、山柰酚-3-O-α-L-吡喃鼠李糖苷(8)、木犀草素-7-O-β-D-吡喃葡萄糖苷(9)、槲皮素-3-O-α-L-吡喃鼠李糖苷(10)、广寄生苷(11)。结论化合物1~11均为首次从该植物中分离得到,其中化合物8和11为首次从本属植物中分离得到。
Objective To study the flavonoids in Nan Liu slaves. Methods The compounds were separated by column chromatography and identified by NMR and physicochemical properties. Results A total of 11 flavonoids were isolated and identified as isorhamnetin (1), kaempferol (2), hemiecine (3), luteolin (4), apigenin ), Quercetin (6), cosmos glycosides (7), kaempferol-3-O-α-L-rhamnopyranoside (8) Glucopyranoside (9), quercetin-3-O-α-L-rhamnopyranoside (10) and glycosides (11). Conclusion Compounds 1-11 were isolated from this plant for the first time. Among them, compounds 8 and 11 were isolated from this genus for the first time.
