Abstract

Catharanthus roseus (L.) G. Don is one of the most important medicinal plants, mainly due to the presence of
anticancer alkaloids. For many years, the phenolic composition of this species remained largely unstudied. Recently,
detailed phytochemical studies using the latest analytical techniques have helped understand the complex phenolic profile
of this species.In this study The investigation of phenolic compounds in Leaves of Catharranthus roseus (L) G. Don by
using different chromatographic methods of separation showed the presence of Kampferol-4
\
-methyl ether and
Quercetin-3-rhamnose-4
\
, 7-dimethyl ether. The structures of these flavonoids were characterized on the basis of their,
UV, 1H-NMR spectral data
