Abstract

Molecular compounds of ascorbic acid or iso-ascorbic acid and quinine are prepared by melting the components together, or by dissolving them in a solvent and precipitating the product, or by double decomposition of their salts in solution. For preserving purposes, an excess of the acid may be used. The products, which are readily water-soluble, are useful therapeutically. Examples are given in which the preparation is effected in an atmosphere of nitrogen. Specification 469,335 is referred to. The Specification as open to inspection under Sect. 91 also describes the use of quinidine and states that ascorbic and iso-ascorbic acids are capable of forming salts with both quinine and quinidine in the molecular proportions of 1 : 1 and 2 : 1. Two further examples are given. This subject-matter does not appear in the Specification as accepted.
