摘要:目的 比較不同蜜炙方法对红芪中毛蕊异黄酮和芒柄花素含量的影响,为其蜜炙最佳工艺的建立提供依据。方法 采用传统炒制、烘制、微波制的方法蜜炙红芪;采用Agilent HC-C18色谱柱(4.6 mm×250 mm,5 ?m);流动相为乙腈-0.01%磷酸水溶液,梯度洗脱(0~12 min,30%~33%乙腈;12~13 min,31%~40%乙腈,13~25 min,40%乙腈),流速1.0 mL/min,检测波长248 nm,柱温30 ℃,进样量10 ?L。结果 红芪不同蜜炙品中毛蕊异黄酮和芒柄花素含量存在差异。红芪烘制炙品中毛蕊异黄酮和芒柄花素含量最高,分别为7.911 6、49.699 6 ?g/g;红芪传统炙品中二者含量最低,分别为4.776 7、37.291 0 ?g/g;红芪生品和红芪微波炙品中二者含量相当,分别为5.080 2、42.798 9 ?g/g和3.983 9、42.314 5 ?g/g。结论 不同蜜炙方法对红芪中毛蕊异黄酮和芒柄花素含量有一定影响,烘制炙法是红芪蜜炙的最优方法。

Abstract: Objective To compare the effects of different methods of honey sunburn on the contents of calycosin and formononetin in Hedysari Radix; To provide the basis for the establishment of the optimum processing technology. Methods By frying (traditional method), baking, and microwave methods put Hedysari Radix under honey sunburn. Agilent HC-C18 column (4.6 mm × 250 mm, 5 ?m) was used; the mobile phase was acetonitrile-0.01% phosphoric acid solution, gradient elution (0–12 min, 30%–33% acetonitrile; 12–13 min, 31%–40% acetonitrile; 13–25 min, 40% acetonitrile) with velocity of 1.0 mL/min; detection wavelength was 248 nm; the column temperature was 30 ℃; sample volume was 10 ?L. Results There was statistical significance in the contents of calycosin and formononetin of different methods of honey sunburn for Hedysari Radix. Among them, the contents of calycosin and formononetin in Hedysari Radix processed by honey roast were the highest, 7.911 6 and 49.699 6 ?g/g, respectively; the contents of calycosin and formononetin in Hedysari Radix processed by traditional method were the lowest, 4.776 7 and 37.291 0 ?g/g, respectively; the contents of calycosin and formononetin in raw Hedysari Radix and Hedysari Radix by honey microwave method were the same, 5.080 2, 42.798 9 ?g/g, and 3.983 9, 42.314 5 ?g/g, respectively. Conclusion Different honey sunburn methods for the contents of calycosin and formononetin in Hedysari Radix have certain effects, and honey roast method is the optimum method.

红芪为豆科植物多序岩黄芪Hedysarum polybotrys Hand.-Mazz.的干燥根,具有补气升阳、固表止汗、利水消肿、生津养血、行滞通痹、托毒排脓、敛疮生肌功效。炙红芪为红芪的蜜炙炮制加工品,具有补中益气功效,用于气虚乏力、食少便溏[1]。毛蕊异黄酮和芒柄花素具有抗氧化、抗病毒、抗缺血、抗菌、降血脂和改善血象等作用[2-4],是红芪的主要活性成分。传统炙红芪炮制时火候不易控制,且翻炒不及时或不均匀都会导致受热不均匀,容易炒焦或炒炙不够,造成蜜炙红芪品相不好,某些成分因温度过高而分解,不利于蜜炙红芪的质量控制和标准化生产。……
