摘要

WE CLAIM :~   1. A, process of preparing hyoscine (scopolamine) iu a pure form from plant material of species such a Datura stramonium which contains the total alkaloids consisting of hyoscyamine and hyoscine which consists of the following steps, namely   a) isolating the total alkaloids from Datura stramonium by macerating the 16 mesh powder of the leaves with 10% ammonia and extracting with benzene, ethy-lene dichioride or toluene, and obtaining the total alkaloids by shaking the benzene extract with dilute sulphuric acid, basifying with alkalies and extracting the alkaloids with chloroform, and concentrating the chloroform extract to obtain the total alkaloids in fairly pure form,   (b) fractionating hyoscine and hyoscyamine by dissol ving  the  total  alkaloids  in  normal  sulphuric acid, neutralising the acidic solution with sodium  bicarbonate to  a  pH  5.6  and  extracting  with  chloroform  when hyoscine (Scopoiaaune; is fractionally extracted leaving behind hyoscyamine, and   (c) purifying scopolamine by preparing ^scopolamine hydrobromide  by  reacting  wiili  nydrobromic  acid  in acetone  solution;  tne  mixture  on  allowing  to stand overnight in ice chest gives nyoscine hydrobromide.
