【摘要】 目的:寻找白术区别于苍术的特征性成分。方法:采用反相高效液相色谱法(RP-HPLC),对白术及苍术的甲醇提取液进行分析。色谱柱:Hypersil ODS C18柱(250mm×4.6mm,5μm);流动相:甲醇-水(60∶40);流速:1.0ml.min-1;检测波长:220nm。结论:白术内酯I、白术内酯Ⅱ和白术内酯Ⅲ为白术区别于苍术的特征性成分,可用RP-HPLC法进行特征性成分分析,鉴别二者。更多还原

【Abstract】 Object:To search the characteristic chemical components of rhizoma atractylodis macrocephalae distinguished from rhizoma atractylodis.Methods:To analyse the methanol extracts of rhizoma atractylodis macrocephalae and rhizoma atractylodis by RP-HPLC.Chromatographic column:Hypersil ODS C18column(250 mm×4.6 mm,5 μm);Mobile phase:methanol-water(volume ratio 60∶40),Flow rate:1.0ml·min-1;UV detection wavelength:220nm Conclusion:AtractylenolideⅠ,AtractylenolideⅡ and Atractylenolide Ⅲ are the characteristic chemical components of atractylodes marocephala distinguished from atractylodes,the method of RP-HPLC can be used to distinguishing that.更多还原
