摘　　要：目的明确炒白芍-炙甘草配伍对化学成分的影响及其与抗炎作用的相关性。方法采用HPLCDAD建立同时测定炒白芍-炙甘草中芍药苷、芍药内酯苷、苯甲酰芍药苷、氧化芍药苷、甘草酸、甘草苷多成分含量的分析方法;建立佐剂性关节炎大鼠模型,给药组分别灌胃炒白芍、炙甘草、炒白芍-炙甘草药液2周,ELISA检测大鼠血清炎症因子白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、前列腺素E_(2)(PGE_(2))含量;采用析因设计、双变量相关分析、多元线性回归方法研究配伍对化学成分的影响及其与抗炎药效的相关性。结果建立HPLC-DAD分析方法,炒白芍-炙甘草配伍后氧化芍药苷、芍药内酯苷、苯甲酰芍药苷含量增加(P<0.05);与模型组比较,各给药组大鼠血清IL-1β、TNF-α、PGE_(2)含量降低(P<0.01),且配伍组血清IL-1β、TNF-α、PGE_(2)含量低于炒白芍组、炙甘草组(P<0.05,P<0.01);析因设计结果显示炒白芍-炙甘草配伍存在交互效应,双变量相关分析结果显示氧化芍药苷、芍药内酯苷、芍药苷、甘草苷、苯甲酰芍药苷、甘草酸含量分别与IL-1β、TNF-α、PGE_(2)含量呈负相关,多元线性回归结果显示甘草苷、甘草酸与IL-1β、TNF-α、PGE_(2)含量呈负相关。结论本研究建立的炒白芍-炙甘草多成分含量分析方法简便快捷、专属性强、准确可靠,可用于其质量评价与控制。炒白芍-炙甘草配伍可抑制炎症因子IL-1β、TNF-α、PGE_(2)表达,且化学成分含量与抗炎作用具有相关性。Objective To investigated the correlation between the effects of the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle on chemical composition and anti-inflammatory effects.Methods An HPLC-DAD method was employed for the simultaneous determination of various components of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,including paeoniflorin,albiflorin,benzoylpaeoniflorin,oxypaeoniflorin,glycyrrhizic acid and glycyrrhizin.An adjuvant-induced arthritis rat model was established.Administration groups were given fried Paeoniae Radix Alba,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,and fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle liquid by gavage for 2 weeks,respectively.Enzyme-linked immunosorbent assay was conducted to detect the levels of inflammatory factors IL-1β,TNF-αand PGE_(2)in serum of each group.Factorial design,bivariate correlation analysis,and multiple linear regression were employed to explore the effect of compatibility on chemical composition and its correlation with anti-inflammatory efficacy.Results The established HPLC-DAD analysis method revealed a significant increase in the content of oxypaeoniflorin,albiflorin and benzoylpaeoniflorin following the compatibility of fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle(P<0.05).Compared with the model group,the contents of IL-1β,TNF-αand PGE_(2)in serum of each administration group decreased(P<0.01),and the contents of IL-1β,TNF-αand PGE_(2)in serum of compatibility group were lower than fried Paeoniae Radix Alba group and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle group(P<0.05,P<0.01).The results from the factorial design indicated the presence of an interaction effect between fried Paeoniae Radix Alba-Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.Bivariate correlation analysis results showed negative correlations between oxypaeoniflorin,albiflorin,paeoniflorin,glycyrrhizin,benzoylpaeoniflorin
