     [摘要] 利用各种色谱方法对丽江獐牙菜Swertia delavayi全草的化学成分进行提取、分离和纯化,得到15个单体化合物,通过波谱数据分析(MS,1H,13C-NMR) 对其结构进行鉴定,分别为红白金花内酯(erythrocentaurin, 1)、红白金花内酯缩二甲醇(erythrocentaurin dimethylacetal, 2)、獐牙菜苷(sweroside, 3)、獐牙菜苦苷(swertiamarin, 4)、龙胆苦苷(gentiopicroside, 5)、贵州獐牙菜苷A(swertiakoside A, 6)、2′-O-乙酰基獐牙菜(2′-O-acetylswertiamarin, 7)、4′-O-[(Z)-对香豆酰基]獐牙菜苦苷(4′-O-[(Z)-coumaroyl]- swertiamarin, 8)、1,5,8-三羟基-3-甲氧基酮(1,5,8-trihydroxy-3-methoxyxanthone, 9)、8-O-β-D-吡喃葡萄糖-1-羟基-2,3,5-三甲基酮(8-O-β-D-glucopyranosyl-1- hydroxy-2,3,5-trimethoxyxanthone, 10)、8-O-[β-D-吡喃木糖-(1→6)-β-D-吡喃葡萄糖]-1羟基-2,3,5-三甲氧基酮(8-O-[β-D-xylopyranosyl-(1→6)-β-D-glucopyranosyl]-1-hydroxy-2,3,5-methoxyxant-hone, 11)、异牡荆素(isovitexin, 12)、齐墩果酸(oleanolic acid, 13)、β-谷甾醇(β-sitosterol, 14) 和胡萝卜苷(daucosterol, 15),其中化合物1~4, 7~11, 13是首次从丽江獐牙菜中分离得到。在体外利用HepG 2.2.15细胞系对得到的单体化合物进行了抗乙肝病毒活性测试,其中化合物1,2,6,7,9和12具有明显的抑制HBV DNV的复制活性,其IC50值为0.05~1.46 mmol·L-1

    [Abstract] Fifteen known compounds were isolated from Swertiadelavayiby silica gel, Sephadex LH-20 and Rp-18 column chromatographies.Based on extensive spectroscopic analysis (MS,1H,13C-NMR), their structures were identified aserythrocentaurin(1), erythrocentaurindimethylacetal(2), sweroside(3), swertiamarin(4), gentiopicroside(5), swertiakoside A(6), 2′-O-acetylswertiamarin (7),4′-O-[(Z)-coumaroyl]swertiamarin(8), 1,5,8-trihydroxy-3-methoxyxanthone(9), 8-O-β-D-glucopyranosyl-1-hydroxy-2,3,5-trimethoxyxanthone(10), 8-O-[β-D-xyl- opyranosyl-(1→6)-β-D-glucopyranosyl]-7,8-dihydroxy-3-methoxyxanthone(11), isovitexin(12), β-sitosterol(13), daucosterol(14), and oleanolic acid(15). Among them, ten ones (1-4, 7-11, 13) were obtained from S. delavayi for the first time. The isolates were evaluated for their anti-HBV activities in HepG 2.2.15 cell line in vitro. The results showed that compound 1, 2, 6, 7, 9 and 12 exhibited significant inhibitory activity on HBV DNA replication with IC50 values from 0.05 to 1.46 mmol·L-1., 百拇医药(曹团武 耿长安 马云保 何康 周宁家 周俊 张雪梅 陈纪军)
