OBJECTIVE To establish a method for the determination of multi-composition in traditional Chinese medicine by module calculation. METHOD In view of the law of lambert-beer, the modulue of two compositions was converted on basis of peak area by HPLC. RESULT The modulues of four groups were gotten and the effects of validation were well. CONCLUSION The(More)
In order to study the accumulation of Fritillaria thunbergii cultivar, peimine content in Xiaye, Kuanye, Duozi and Xiaosanzi bulbs of different sizes and parts was determined by HPLC-ELSE. The results indicated that the peimine content varied significantly with the cultivar type, the size and part of bulb. The distribution laws of peimine were as follow:(More)

OBJECTIVE To establish the determination method of 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside in Yangan Oral Liquid. METHOD 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside was determined by HPLC on C18 column, in acetonitrile-water (14:86) solution as a mobile phase, detection wavelength as 320 nm. RESULT This method showed a good linear(More)
OBJECTIVE To establish the quality control standard for Xueyakang capsule. METHOD Radix Rehmanniae, Cacumen Platycladi, Folium Artemisiae Argyi, Folium Nelumbinis were identified by TLC, and the content of quercitrin was determined by HPLC. RESULT The TLC sports developed was fairly clear, the HPLC method showed good repeatability, and the average(More)
OBJECTIVE To establish the methods of identification and assay in Qianshan Huoxue Gao. METHOD Using TLC to identify Sanchi, Dragon's Blood and using HPLC to determine the content of ginsenoside Rg1. RESULT The linear range of ginsenoside Rg1 was from 0.153 9 to 1.026 microg. The average recovery was 97.4%, RSD was 2.1%. CONCLUSION The methods are(More)
OBJECTIVE To study the differences in pollen morphology and karyotype among main Fritillari thunbergii cultivars. METHOD Pollen morphologies of three F. thunbergii cultivars were examined by scanning electron microscopy (SEM), and the chromosome numbers and karyotypes were studied by applying traditional squash technique. RESULT The pollen shape of F.(More)
