Pharmacognostical and Phytochemical Studies of Delonix regia

In the present study, an attempt was made to investigate pharmacognostical and phytochemical screening of Delonix regia seeds of family Leguminosae. The seeds were collected from its pods after authentication, shade dried and various pharmacognostical and phytochemical analysis were performed. The pharmacognostical parameters studied were macroscopy, microscopy, physicochemical analysis and chromatography. The coarsely powdered seeds were extracted with various extract and phytochemical screening were performed. The phytochemical screening revealed that the presence of secondary metabolites such as Flavonoids, sterols, triterpenoids, saponins and fixed oils in Delonix regia seeds. All the parameters were studied according to the WHO and Pharmacopoeial guidelines. HPTLC and TLC analysis were also performed. These pharmacognostical data are helpful to determine its identity, where as the Photochemical studies are useful to bring out the various pharmacological activity it may posses, based on the active constituent present in them.
