由于安眠镇静药物的常规检验方法常需较大量的试样,而检材却往往达不到这一要求,为此我们在总结经验的基础上,选择四种层析条件对三种巴比妥类药物和七种非巴比妥类药物进行了薄层鉴定,得到较理想的结果。实验方法1.薄板的制备取硅胶(浙江黄岩硅胶厂,200目以上),用1%的羧甲基纤维素钠(CMC)的水溶液调制成糊状后,涂布成约0.3mm 厚的薄板,固化后,于105℃活化一小时,置干燥器中备用。
Because sleeping sedative drugs routine testing methods often require a large number of samples, but the samples are often not meet this requirement, so we based on the experience, select four chromatographic conditions on three kinds of barbiturates Drugs and seven non-barbiturates were thin-layer identification, get better results. Experimental methods 1. Preparation of the sheet Take silica gel (Zhejiang Huangyan silica gel plant, 200 mesh or more), with 1% sodium carboxymethyl cellulose (CMC) aqueous solution was prepared into a paste, coated into a sheet of about 0.3mm thick , After curing, activated at 105 ℃ for one hour, set aside the dryer spare.
