ABSTRACT
OBJECTIVE:To establish a meth od for the simultaneous determination of 7 active components in Mori Australis Cortex and Mori Cortex from different sources in Chongqing area ,so as to provide reference for improving the quality control standards of Mori Australis Cortex and Mori Cortex and comparing the equivalence of their quality. METHODSHPLC method was used to determine the contents of neochlorogenic acid ,mulberroside A ,chlorogenic acid ,astragalin,kaempferol,morusin and isoquercetin in 58 batches of Mori Australis Cortex and Mori Cortex. The chromatographic column was Diamonsil C 18 with mobile phase consisted of 0.1% formic acid solution-acetonitrile (gradient elution ) at the flow rate of 1.0 mL/min. The detection wavelength was 280 nm,column temperature was 30 ℃,and the injection volume was 10 μL. Using SPSS 22.0 software, independent sample t-test,principal component analysis and cluster analysis were used to analyze the content difference of the above-mentioned 7 active components in Mori Australis Cortex and Mori Cortex. RESULTS :There was a good linear relationship between the peak area and the concentration of the above 7 active components (r≥0.999 0). The RSDs of precision ,stability(24 h),repeatability,durability and recovery were less than 3%. The average contents of neochlorogenic acid ,mulberroside A , chlorogenic acid , astragalin, kaempferol, morusin and 023-58576130。E-mail:1025473978@qq.com isoquercetin in Mori Australis Cortex were 0.304,22.462, 1.730,1.308,1.593,2.842 and 0.657 mg/g,respectively. Those of Mori Cortex were 0.305,22.995,2.486,2.438, 2.916,4.158 and 1.264 mg/g,respectively. The results of independent sample t-test showed that only the content of kaempferol in the above 7 active components of Mori Australis Cortex and Mori Cortex had significant difference (P<0.05). The results of principal component analysis and cluster analysis showed that there was no significant difference in the contents of above 7 active components between Mori Australis Cortex and Mori Cortex. CONCLUSIONS:The established HPLC method is simple ,sensitive and accurate ,which can provide a reference for improving the quality control standard of Mori Australis Cortex and Mori Cortex. Mori Australis Cortex and Mori Cortex have certain quality equivalence in main active components ,and the Mori Australis Cortex from M. australis and M. cathayana can be used as a substitute for the Mori Cortex.
