Abstract:
OBJECTIVE:To establish the HPLC characteristic chromatogram of pheretima,and compare the differences of the main ingredient contents of Guangdong pheretima and Shanghai pheretima and the chromatogram differences among pheretima and 3 other animal drugs. METHODS:Pheretima HPLC characteristic chromatogram method was adopted to determine the characteris-tic chromatograms of 16 Guangdong pheretima,8 Shanghai pheretima,3 eupolyphaga,3 hirudo and 3 catharsius. Similarity evalua-tion and t test were used to analyze the differences of chromatogram data of 5 animal drugs. RESULTS:The established HPLC char-acteristic chromatogram method firstly identified 11 common characteristic peaks,including 6 nucleosides,4 nucleobase and 1 ami-no acid;and it could be used for the identification of pheretima from eupolyphaga,hirudo and catharsius;the differences of main ingredient contents in the characteristic chromatogram of Guangdong pheretima and Shanghai pheretima were firstly studied. The contents of xanthine and adenosine in Guangdong pheretima were higher than Shanghai pheretima,while the contents of uridine, guanosine and 2′-deoxy guanosine in Shanghai pheretima were higher than Guangdong pheretima. A new index S,calculated by these 5 constituents,was successfully applied to distinguish the 2 kinds of pheretima. CONCLUSIONS:The characteristic chro-matogram can be used for the identification of pheretima,and can provide reference for the pharmacodynamic differences study of Guangdong pheretima and Shanghai pheretima.
