摘要
为了阐明藏药甘扎嘎日药效物质基础,利用各种色谱技术对甘扎嘎日(秀丽莓)Rubus amabilis 干燥茎进行化学成分研究,从中分离得到11个化合物,并通过理化性质与波谱分别鉴定为1,8-二羟基-3,7-二甲氧基 NFDE8 酮(1),1-羟基-3,7,8-三甲氧基 NFDE8 酮(2),1,8-二羟基-3,5-二甲氧基 NFDE8 酮(3),山柰酚-3-O-(6"-反式-对-肉桂酰基)-β-D-吡喃葡萄糖苷(4),槲皮素(5),山柰酚(6),金丝桃苷(7),木犀草素-7-O-β-D-吡喃葡萄糖苷(8),芹菜素-7-O-β-D-吡喃葡萄糖苷(9),异牡荆素-7-O-葡萄糖苷(10),原花青素 B4(11)。化合物 1~6,10~11 首次从甘扎嘎日中分离得到,其中化合物 1~3 首次从悬钩子属中分离得到。
In order to illuminate the effective compounds in Tibetan medicine kandrakari, chemical composition of dry stems of Rubus amabilis were studied by means of various chromatographic techniques, leading to the isolation of 11 compounds. On the basis of spectroscopic data, their structures were elucidated as 1,8- dihydroxy -3,7-dimethoxyxanthone(1), 1-hydroxy-3,7,8-trimethoxyxanthone (2), 1,8-dihydroxy-3,5-dim ethoxyxanthone(3), kaempfero-3-O-(6"-trans-p-coumaroyl)-β-D-glucopyranoside(4), quercetin(5), kaempferol (6), hyperoside (7), luteolin-7-O-β-D-glucopy ranoside (8), apigenin-7-O-β-D-glucopyr anoside(9), isovitexin-7-O-glucoside(10), and procyanidin B4(11). Compounds 1-3 were isolated from the Rubus genus for the first time,and compounds 1-6, 10-11 were isolated from R. amabilis for the first time.
