Abstract:VE:The method was reported for determination of total alkaloids in Wanbeimu (Fritillaria anhuiensis) by acid dye colorimetry. METHODS: The conditions of quantitative analysis were chosen by acid dye colorimetry. RESULTS:The approprite analysis was performed on 2ml 0. 001 Mol L-1bromothymol blue solution,detected at 410 nm. The linearity was established for total alkaloids in the range of 2.0-10.0 ug ?ml-1. CONCLUSION :This method was sensitive,accurate and reproducible.
Keywords:Fritillaria anhuiensis  total alkaloids  acid dye colorimetry
