ABSTRACT
Objective@#To study the effects of different compatibility ratios of Centella asiatica- Rhubarb on the dissolution rates of madecassoside and asiaticoside.@*Methods@#By using the HPLC method to analyze the content of madecassoside and asiaticoside in the Centella asiatica extract solution as well as Centella asiatica - Rhubarb extract solution with 6 different kinds of compatibility ratios. The tests were carried out by Thermo C18 (250 mm×4.6 mm, 5 μm) by isocratic elution with acetonitrile and 2 mmol/L of beta-cyclodextrin solution as mobile phase at a flow rate of 1 ml/min, the column temperature was 30 ℃ and the detection wavelength was 205 nm.@*Results@#Compared with the Centella asiatica extract solution, the dissolution rate of madecassoside decreased significantly with the increase of the proportion of rhubarb. The combination of Centella asiatica and Rhubarb had little effect on the content of asiaticoside.@*Conclusions@#Considering the clinical application and efficacy of Centella asiatica, the optimal ratio of Centella asiatica-Rhubarb is 101 and 151.
