番木鼇生物鹼的含量测定,各国药典方法均不同。中国药典的含量测定方法,在加硫酸液后,用氯仿洗滌时以及洗滌后加氨溶液使成鹼性再用氯仿抽提时,均易形成难以分層的混悬液或乳化液,此因供試品中加入硫酸液、蒸溜水、洗液及氨溶液,使容积增加太多,同时其中有一小部份的色素、脂肪質、树脂的存在,經振搖后以至产生上述現象。若已發生此等現象(在加氮溶液后尤其容易乳化),必須放置很久时间;有的虽放置多时也不易分清。
The determination of the content of alkaloids in P. amurense differs among the methods in different countries. The Chinese Pharmacopoeia’s method for determining the content of the Pharmacopoeia is easy to form suspensions or emulsions that are difficult to separate due to the addition of sulphuric acid solution, washing with chloroform, and the addition of ammonia after washing to make alkaline and then extract with chloroform. Sulfuric acid, distilled water, lotion, and ammonia solution were added to the test sample to increase the volume too much. At the same time, a small amount of pigments, fatty substances, and resins were present, and the above phenomenon was observed after shaking. If these phenomena have occurred (especially easy to emulsify after the addition of nitrogen solution), they must be placed for a long time; some are difficult to distinguish even though they are placed for a long time.
