A sensitive, simple and selective spectrofluorimetric method
has been proposed for determination Captopril (CPT) in pure form
and pharmaceutical preparations. This method depends on the
formation of complex between Captopril and Copper (II) at
pH=3.5.
The voltammetric behavior of captopril in presence of
copper ions was investigated by using adsorptive cathodic stripping
voltammetry at hanging mercury drop electrode.
A new, simple and sensitive kinetic spectrophotometric
method has been proposed for the determination of tropicamed
(TPC) in pure and pharmaceutical formulations. The method is
based on oxidation TPC by potassium permanganate in strong
alkaline m
edium (pH=12) to form green colored product with
absorbance maximum at 610nm.
Simple, accurate and reliable spectrophotometric method
has been developed for the quantitative determination of
Cephalosporins: Cefaclor, Cefalexin, Cefadroxil in pure and
pharmaceutical formulations. The method is based on the
determination of that in aqueous medium pH=6.45 at
25±0.5ºC.
The history of medicine using medicinal plants goes back thousands of years, and according to the reports of the World Health Organization, many of the world's people mainly use the plant to treat many diseases, and one of the plants that is famous for its widespread use is the leaves of Ginkgo biloba.
