香陈颗粒的薄层色谱鉴别
LiShiZhen Medicine and Materia Medica Research(2006)
Abstract
目的采用薄层色谱法(TLC)鉴别香陈颗粒中香附、陈皮、山楂、甘草。方法香附鉴别以苯-醋酸乙酯-冰醋酸(92∶5∶5)为展开剂,以二硝基苯肼试液为显色剂;陈皮鉴别以醋酸乙酯-甲醇-水(100∶17∶13)为展开剂,并以甲苯-醋酸乙酯-甲醇-水(20∶10∶1∶1)的上层溶液进行2次展开,以三氯化铝试液为显色剂;山楂鉴别以氯仿-丙酮(9∶1)为展开剂,以10%硫酸乙醇溶液为显色剂;甘草鉴别以醋酸乙酯-甲醇-冰醋酸-水(30∶2∶2∶4)上层液为展开剂,以10%硫酸乙醇溶液为显色剂。结果各色谱斑点清晰,分离度好,阴性对照无干扰。结论该鉴别方法简便,可靠,灵敏,专属性强,可用于香陈颗粒的质量控制。
