用二氯甲烷液-液萃取氮吹浓缩法萃取水和废水中的多菌灵，取浓缩纯化后的有机相直接进样到高效液相色谱仪，用二极管矩阵检测器检测，根据保留时间外标法定量。

The results showed: when TLC solvent system was: chloroform - methanol - diethyl amine = 90:9:1, alkaloids from lotus leaves were well isolated, and five components were isolated and identified by spraying Dragendorff reagent. The optimal conditions of HPLC solvent system were: methanol- water - diethyl amine = 75:25:0.0125. Under the conditions, components of alkaloids from lotus leaves were separated very well, and ideal RP-HPLC peaks were obtained.5、Methods of High Speed Counter Current Chromatography and preparative High Performance Liquid Chromatography applied to identify and purify alkaloids from lotus leaves were set up. When solvent system of HSCCC was: chloroform - methanol - water (pH=4.00)= 4:3:2, speed of chromatogram was 700rpm, flow speed of the mobile phase was 2mL/min, four pure components relatively were attained by isolation and purification.

结果表明：薄层层析溶剂系统为氯仿：甲醇：二乙胺=90：9：1，使荷叶中的生物碱达到了较好的分离效果，并用改良的碘化铋钾试剂喷雾显色，共分离鉴别出了5种荷叶生物碱；分析型HPLC分析检测的较优溶剂系统为甲醇：水：二乙胺=75：25：0.0125，使荷叶生物碱的各个组分达到了基线分离，并获得了较好的峰形。5、建立了高速逆流色谱和制备型HPLC技术分离纯化荷叶生物碱的具体方法。H(来源：ABC46论文网www.abclunwen.com)SCCC法在溶剂系统为氯仿：甲醇：pH4.00的水=4：3：2，色谱仪转速为700rpm，流动相流速为2mL／min的条件下，分离纯化得到了4个纯度较高的化合物。
