PHYTOCHEMICAL ANALYSIS AND ANATOMICAL STUDY OF TWO SPECIES OF CESTRUM FROM CHANDIGARHAbstract
Family Solanaceae is known for its tropane alkaloids which have many medicinal properties. In our study two Cestrum species namely Cestrum diurnum and Cestrum nocturnum which are also ornamental plants are studied as different parts of the plants possess anti-bacterial, anti-malarial, analgesic, anti-inflammatory, inhibitory effect on central nervous system and wound healing properties. The present study was undertaken to analyse the presence of various phytochemicals such as alkaloids, flavonoids, terpenoids, saponins, steroids through preliminary qualitative phytochemical screening of the leaf extract. HPLC(High Performance Liquid Chromatography) was used for the qualitative and quantitative active principle analysis which revealed the presence of nicotine and nornicotine as major alkaloids and comparative study of the two species showed the presence of these alkaloids in large quantity in Cestrum diurnum. The detailed anatomical studies of the part(s) used help in the correct easy identification of the commercial drug in its purest form.
