测定本品含量中,我们采用过中国药典上顚茄浸膏的方法,但因本品中含有较多的树脂等易乳化物质,结果并未成功。以后考虑先称一定量,经低温干燥后分取定量(先研细),用速氏法抽出,但考虑到手续过多,不合于现实要求。后来采用了日本药局方上方法,手续简便,结果较一致,本法系根据其原理用了一些改进,今介绍如下。精密称取东莨菪浸膏2克于分液漏斗中,加水10毫升,氨试液8毫升及95%醇5毫升。缓缓振摇并放置使溶解后,加入乙醚30毫升,振摇分离后分取醚液于另一分液漏斗中,残液再各用醚10毫升抽取三(或 Determination of the content of this product, we have adopted the Chinese Pharmacopoeia Shang Ju extract, but because this product contains more easily emulsified resin, the results did not succeed. Consider after weighing a certain amount, after drying at a low temperature and then quantitative (first research fine), with the Fast method of extraction, but taking into account too many formalities, not realistic requirements. Later, the Japanese Pharmacopoeia on the method, the procedure is simple, the results are more consistent, this law based on the principle of using some improvements, introduced below. Accurately weighed scopolamine extract 2 g in a separatory funnel, add water 10 ml, ammonia solution 8 ml and 95% alcohol 5 ml. Slowly shake and place to dissolve, add diethyl ether 30 ml, shake the separation ether solution was separated in another separatory funnel, the residue and then ether each 10 ml extracted three (or
