麦角中生物硷的含量测定,一般均按中国药典及 N.F.方法.但这两个方法只能测出总生物硷和水溶性生物硷的含量,对最有效成份——水溶性生物硷中的麦角新硷无法单独测定.Grove 曾用提取方法分离麦角新硷和麦角异新硷,进行个别定量,但手续麻烦,而且提取液体积较大,含量少时测定困难.Carless 用纸纤维柱层离法分别测定麦角中各种生物硷含量,样品用量很少,全部过程需两天.根据作者之一用硅藻土柱层离法自麦角生药中提取麦角新硷的结果,我们认为有可能达到定量目的,因此进行了以下试 The content of bio-germanium in ergot is generally measured according to Chinese Pharmacopoeia and NF method. However, these two methods can only measure the content of total biological and water-soluble bio-antimony. For the most effective ingredient, ergot in water-soluble bio-indole. The new wolfberry cannot be measured alone. Grove used the extraction method to separate ergot and new ergot, and carried out individual quantification, but the procedure was inconvenient, and the volume of the extract was large, and the determination was difficult when the content was low. Carless paper fiber column delamination method The determination of various bio-germanium contents in Ergot is very small, and the total amount of sample is two days. According to one of the authors’ methods of diatomite column delamination, the new ergot from Erjiao crude drug was extracted. We believe that it is possible to achieve quantitative results. , so the following test was conducted
