A COMPARATIVE INVESTIGATIONAL STUDIES ON PHARMACOGNOSY, PHYTOCHEMICAL ASPECTS AND ANTI-MICROBIAL ACTIVITY OF A DELONIX REGIA FLOWERS AND SEEDS ON METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS.

An attempt was made to report the comparative pharmacognostic and phytochemical analysis of the flowers and seeds of Delonix regia by determination of ash values, extractive values, moisture content and fluorescence analysis.The aqueous extract of seeds and flowers reveal the chemical constituents by preliminary phytochemical screening and the extracts were subjected to evaluate the comparative anti-microbial activity of flowers and seeds of Delonix regia by agar bore well assay on gram stain microbes Methicillin resistant Staphylococcus aureus .The powdered flowers and seeds were subjected for the proximate analysis. Major Extraction was carried out by soxhlet extraction method using ethanol as solvent. The comparative anti-microbial activity of flowers and seeds of Delonix regia was evaluated in vitro. A greenish solid matter of 4.53 % w/w was obtained from the dried seeds and a pale yellow solid matter of 2.15 % w/w was obtained from the dried flower petals powder. Investigation of ethanolic extract of Delonix regia seeds and flowers produced a significant anti-microbial activity and the MIC values were found to be 1.75µg/ml and 2.0µg/ml respectively.The present work justifies the folklore claim of the medicinal importance of Delonix regia seeds and flowers for treatment of high resistant microbial strains, which was scientifically proven.
