The operating curve (A=2.100 9 C+0.211 6 mg/mL)) was found to be linear over the range of 0~160 μg/mL acetate alisol B in ethanol (r =0.999 7). The molar absorptivity is 5.4×102 L·mol-1·cm-1.The detection limit is 11.143 μg/mL and the recovery is 93.0%~109%. The simple, rapid and lowcost method has been successfully applied to evaluate the quality of Alisma orientalis in our GAP (Good Agricultural Practice) research and practice in Fujian province.

建立了利用便携式小型光谱仪测定中药泽泻中三萜醇酮类化合物总量的比色测定方法.本方法采用具有C 3羰基的甾酮类化合物的专属性Zimmerman显色反应,检测波长为560nm.以23 乙酰泽泻醇B的吸光度和浓度作工作曲线,回归方程为A=2.1009C+0.2116(mg/mL),相关系数为0.9997,23 乙酰泽泻醇B的浓度在0~160mg/mL范围内符合比耳定律,表观摩尔吸收系数ε=5.4×102L·mol-1·cm-1,检出限为11.143mg/mL,回收率为93.0%~109%.该方法简单、快速、廉价,已成功应用于福建地道药材泽泻GAP过程质量控制及泽泻药材品质的评价,指导泽泻药材的生产,具有重大的经济效益和社会意义.
