研究了红芪药材的高效液相色谱（ HPLC ）指纹图谱与抗肝纤维化作用之间的谱效关系。采用四氯化碳（CCl4）?花生油（体积比为4∶6）皮下注射（0?1 mL／10 g，1次／5 d）致小鼠肝纤维化，同时灌胃给予红芪各不同溶剂提取物（10 g原药材／kg，1次／d），5周后测定与肝纤维化有关的各血清指标及肝重指数，结果乙醇提取物药效最佳。运用灰色关联度和偏最小二乘法研究了不同产地红芪药材乙醇提取部位的HPLC指纹图谱与抗肝纤维化药效之间的谱效相关性。结果红芪乙醇提取物中多数成分与抗肝纤维化药效均有高度关联性（＞0?8），表明该药效是红芪中所有成分共同作用的结果；同时鉴定出腺苷、毛蕊异黄酮及芒柄花苷3种成分，其中腺苷及毛蕊异黄酮对药效有较大贡献。
The spectrum?effect relationship on anti?hepatic fibrosis effect of Radix Hedysari was explored based on high performance liquid chromatographic technique. Hepatic fibrosis was induced in mice by administering a subcutaneous injection of carbon tetrachloride?peanut oil ( 4∶6, v/v) continuously for 35 d at a interval of 5 d (0?1 mL/10 g). And at the same time of modeling, the different extracts of Radix Hedysari were administered orally once daily at a dose of 10 g/kg. The ethanol extract of Radix Hedysari was specified to be most effective on anti?hepatic fibrosis by determining the levels of alanine aminotransferase, aspartate transami?nase, total?protein, albumin, albumin/globulin ( ALT, AST, TP, ALB, and A/G) in serum and relative liver weight. Subsequently, the grey relational degree analysis and partial least squares analysis were employed to reveal the correlation between chromatographic fingerprint of etha?nol extract of Radix Hedysari from 10 different geographical origins and its anti?hepatic fibrosis efficacy. The results suggest that most chemical constituents of Radix Hedysari have a high correlation with the effect of anti?hepatic fibrosis (>0?8 ) , which indicates that the effect is related to the various components in Radix Hedysari. Adenosine, calycosin and ononin in etha?nol extract of Radix Hedysari have been identified separately among which adenosine and caly?cosin made the great contribution to the anti?hepatic fibrosis effect.
