Abstract

Ayurveda, an ancient system of medicines detailing a number of medicinal plants and their activities in human or animals. The present research work was aimed to develop an analytical procedure for the determination of catechins in the selected plant B.Ciliata. It is famously known as stone flower/ stone breaker having various biological activities like anti urolithiatic, antiviral, antidiabetic antitumor and cardio protective activity. The methanolic extract of the plant is isolated and a method is developed by using RP HPLC for the determination of catechins in the crude plant extract using a C18 column (200*4.6mm, 5μ) and detected at 241 nm. The method is validated for its system suitability, Linearity, Accuracy, Precision, Robustness and sensitivity as per the ICH guidelines Q2(R1) to meet the analytical procedure in academic and industrial usage 19.

毛纤毛虫中儿茶素的分离、表征及植物化学筛选、分析方法的建立及RP - HPLC测定方法的验证
阿育吠陀,一种古老的药物体系,详细描述了许多药用植物及其对人类或动物的作用。本研究旨在建立一种测定植物纤毛中儿茶素含量的分析方法。它具有抗尿石、抗病毒、抗糖尿病、抗肿瘤和心脏保护等多种生物活性,被称为石花/破石剂。采用反相高效液相色谱法(RP - HPLC)分离了该植物甲醇提取物,建立了测定粗提取物中儿茶素含量的方法,色谱柱为C18 (200*4.6mm, 5μ),检测波长为241 nm。根据ICH指南Q2(R1)验证了该方法的系统适用性、线性度、准确度、精密度、稳健性和灵敏度,以满足学术和工业使用的分析程序19。
