Abstract
Objective To develop a method for determination of assiticoside in Centella asiatica and its formula particles. Methods Hypersil ODS C18 column was used(4.6 mmá250 mm,5 μm),withacetonitrile-water(v/v=3:8) as mobile phase, and a flow rate of 0.6 ml/min. Results The result showed that the calibration curve was linear in the range of 23.2~580.0 μg/ml for asiaticoside, intra-day and inter-day precision results were 2.1% and 3.6%, the average recovery of asiaticoside were 95.2%(RSD=3.2%, n=6) in centella asiatica and 104.6%(RSD=1.0%,n=6) in its formula particles. The contents of asiaticoside in 5 medicinal materials were 0.33%,0.52%,0.22%,0.28% and 0.39%;while in 5 formula particles were 0.40%,0.44%,0.39%,0.44% and 0.42%. Conclusions The method was simple and accurate for quality control of Centella asiatica and its formula particles.
