摘要
在水浴辅助条件下利用超声处理,提取厚朴中酚类物质,选出最佳方案。采用正交试验设计,HPLC测定厚朴中厚朴酚与和厚朴酚的含量,色谱条件SinoChrom ODS-BP5μm4.6 mm×150 mm色谱柱,流动相为甲醇-水(体积比78∶22),流速为1.0 mL/min,检测波长294 nm,柱温30℃,进样量20μL。在乙醇浓度为80%,浸泡时间50 min,浸泡温度50℃,超声时间为20 min的条件下,酚类物质分离好,提取率高。
The schemes for extracting phenolic materials from Magnolia officinalis were studied by orthogonal design under the condition of water bath and ultrasonic treatment.The results showed that the optimal scheme to extract magnolol and honokiol was as follows.The chromatographic conditions included that the SinoChrom ODS-BP(4.6 mm×150 mm,5μm) was used as chromatographic column by HPLC isolation;the methanol water(78∶22) as mobile phase;the flow rate was 1.0 mL/min,the detection wavelength was 294 nm,the column temperature was 30℃ and the injection volume was 20 μL.The highest extracting rate for the phenolic materials and the best separation effect were obtained under the conditions of 80% ethanol as the reagent with 20 min ultrasonic treatment,soaking for 50min at 50℃.
