Abstract:

     Caesalpinia pulcherrima belonging to family Caesalpiniaceae is distributed throught out India. Commonly it is known as Peacock-flower. Plant shows diterpenoids, isovouacaperol, sitosterol and flavonoids. The plant is considered as emmenagogue, purgative and stimulant, abotificient and also used in bronchitis, asthma and malarial fever, leaves used as antipyretic, antimicrobial. Flower also shows antioxidant and antiviral activity. The present study deals with the macroscopical and microscopical studies of Caesalpinia pulcherrima leaf. Macroscopically, the Caesalpinia pulcherrima is compound leaf, ovate shape, entire margin and glabrous surface, asymmetrical base, small petiole. The microscopic study showed presence of collenchyma, vascular bundle, spongy parenchyma, palisade cells, stomata. Some distinct characters were observed while studying the transverse sections. Physiochemical studies revealed total ash, acid insoluble ash, water insoluble ash, loss on drying, alcohol soluble extractive, water soluble extractive and preliminary phytochemical studies of the leaves were also carried out. The present study might be useful to supplement information in regard to its identification parameters.

Results:

- The microscopic study showed presence of collenchyma, vascular bundle, spongy parenchyma, palisade cells, stomata. Some distinct characters were observed while studying the transverse sections.

- Physiochemical studies revealed total ash, acid soluble ash, water insoluble ash, loss on drying, alcohol soluble extractive. Preliminary phytochemical studies of the leaves were also carried out.
