测定本品含量中,我们采用过中国药典上颠则茄浸膏的方法,但因本品中含有較多的树脂等易乳化物质,結果並未成功。以后考虑先称一定量,经低温干燥后分取定量(先研細),用速氏法抽出,但考虑到手续过多,不合于现实要求。后來采用了日本药局方上方法,手續簡便,結果較一致,本法系根据其原理作了一些改进,今介紹如下。精密称取东莨菪浸膏2克于分液漏斗中,加水10毫升,氨試液8毫升及95%醇5毫升。緩綏振摇並放置使溶解后,加入乙醚30毫升,振摇分离后分取醚液于另一分液漏斗中,殘液再各用醚10毫升抽取三(或

In the future, it is considered that a certain quantity shall be weighed first, and after the low-temperature drying, the quantity shall be quantified (first studied), and then extracted using the Sud method. However, considering the excessive procedures, it is not suitable for the actual requirements. Later, the Japanese Pharmacopoeia method was adopted. The procedures were simple and the results were more consistent. This law made some improvements based on its principles. This is introduced as follows. Accurately weigh 2 g of Toad extract in a separatory funnel, add 10 ml of water, 8 ml of ammonia solution and 5 ml of 95% alcohol. Slowly shaking and place to dissolve, add 30 ml of diethyl ether, shake to separate and then separate the ether solution into another separatory funnel, and then the remaining solution is extracted with ether 10 ml each (or
