摘要: 对黄刺玫(Rosa xanthina Lindl)果实的化学成分及其体外延长凝血酶原时间(PT)进行研究。采用硅胶、Sephadex LH-20、MDS柱色谱以及半制备高效液相色谱等方法进行分离纯化,并运用NMR、MS等波谱方法对所分离的化合物进行结构鉴定。结果从黄刺玫果实75%乙醇提取物中分离鉴定6个化合物,分别为槲皮素-3-O-α-L-鼠李吡喃糖苷(1)、槲皮素-3-O-(6″-O-反式香豆酰基)-β-D-葡萄糖苷(2)、山奈酚-4′-O-β-D-吡喃葡萄糖苷(3)、槲皮素-4′-O-β-D-吡喃葡萄糖苷(4)、1,2-二(4-羟基-3-甲氧基苯基)-1,3-丙二醇(5)、2,3-二羟基-1-(3-羟基-4-甲氧基苯基)-1-丙酮(6)。其中化合物6是首次从本属植物中分离得到,化合物1~5为首次从黄刺玫中分离得到。体外血浆PT测定结果表明,化合物1~4与空白对照相比(P<0.05) 均显示具有延长凝血酶原时间作用,进一步对化合物1的延长凝血酶原时间(PT)进行量效关系研究,结果显示在浓度不小于27 mM时,化合物1显示明显延长凝血酶原时间作用。

Abstract: The present study aimed to investigate chemical constituents from Rosa xanthina Lindl and their effects on prothrombin time in vitro. Six compounds were obtained from the 75% ethanol extract of the fruits of R.xanthina by silica gel,Sephadex LH-20,MDS and semi-preparative HPLC technology.Based on MS,NMR spectroscopic methods,their structures were elucidated as quercetin-3-O-α-L-rhamnopyranoside (1),quercetin-3-O-(6′′-O-trans-p-coumaroyl)-β-Dglucopyranoside (2),kaempferol-4′-O-β-D-glycopyranoside (3),quercetin-4′-O-β-D-glucopyranoside (4),1,2-bis (4-hydroxy-3-methoxyphenyl)-1,3-propanediol (5),2,3-dihydroxy-1-(3-hydroxy-4-methoxyphenyl)-1-propanone (6).Compounds 1-5 were isolated from the plant for the first time,and compound 6 was isolated from this genus for the first time.Compounds (1-4) showed significant prolongation of prothrombin time comparing with control.In addition,when the concentration was higher than 27 mM,compound 1 showed significant prolongation of prothrombin time.

Key words: Rosa, Rosa xanthina Lindl, chemical constituents, prothrombin time
