Abstract
[Objective]To study the differences between medicinal and non medicinal parts of loquat flowers,as well as the effects of mixing non medicinal parts.[Method]HPLC was performed on a column of SHIMSEN Anklyo C18(4.6 mm×100 mm,5 μm)using methanol(A)and 0.1%ammonium acetate(B)as the mobile phase in a gradient elution;the flow rate was 1.0 mL/min;the detection wavelength was 210 and 355 nm;the column temperature was 35 ℃ and the injection volume was 10 μL;determined the content of seven chemical components,inclu-ding hyperoside,isoquercitrin,quercitrin,quercetin,ursolic acid,oleanolic acid and corosolic acid,in the medicinal and non medicinal parts of loquat flowers;and analyzed the data.[Result]The content and distribution patterns of various chemical components in the flowers and buds of loquat flowers were relatively similar;there were certain differences in the content and distribution patterns of various chemical components in other parts compared to the flowers or buds of loquat flowers.[Conclusion]The medicinal part of loquat flowers is more clearly and reasonably described as a"dry inflorescence with buds".关键词
