摘 要:应用TLCS法测定天芎头痛宁胶囊中天麻素含量,样品以无水乙醇提取,残渣以正丁醇溶解,经水提取和氧化镁吸附,排除了水溶性杂庙的干扰,以硅胶G为薄层吸附剂,氟仿一甲醇一乙酸(6:2:0.15)为展开剂,10%磷钼改乙醇溶液为显色剂,用CS-930薄层扫描仪,在λ_S=540nm,λ_R=475nm波长处测定含量,本法平均加标回收率为99.70%,同一样品5次独立测定的RSD为2.64%。The content of Gastrodine in Tian Xiong Tou Tong Ning Capsule was detrmined by TLCscanner. The sample was refluxcd and extracted with ethanol. The residue was dissolved in n-butanol,extracted with water and adsorbed wirh magnesium oxide in order to get rid of water-soluble impurities.Applying chloroform-methyl-36% acetic acid (62.0.15)as the solvent developer system on silica gel G plateand10% phosphomolydic acid alcohol solution as the color dcveloping reagent, CS-930 dual wavelengthscanner was used to determine the content of gastrodine at λ_S=540nm and λ_R=475nm. The recovery rate of themethod is 99.70% and RSD is 2.64%(N=5).
