It is Key Words commanly known as yellow poinciana, golden flame and copper pod. In Peltophorum Ayurveda it is used in many conditions and traditionally it is proved to be pterocarpum, used in the treatment of stomatitis, insomnia, constipation, ringworm, Flavonoids, dysentery, muscular pains, sores and ski n disorders. The objective of the Phytochemical present study involves the phytochemical investigation of the Peltophorum pterocarpum flowers. The flowers are extracted with the 70 % ethanol and investigation and phytochemical evaluation was carried out for the determination of golden flame Carbohydrates, Alkaloids, Flavonoids, Sterols, Tannins, phenolic compounds and Aminoacids. Results revealed the presence of Carbohydrates, Alkaloids, Flavonoids, Sterols, Tannins, phenolic compounds and Aminoacids. INTRODUCTION: Peltophorum pterocarpum is a eye lotions and to treat pains and sores. common deciduous tree grown in topical Leaves of the plant are used in treating skin contries. Different names of this plant are disorders in the form of decoction. Stem Yellow Poinciana, golden flame, copper infusion of this plant used to treat dysentery, pod, Rusty shield bearer and Yellow gargles, tooth powder and to reduce muscle flamboyant. The plant grows at a height of pain. The flowers are used as astringent to about 40 to 50 feet and it spreads about 30 to relive intestinal disorders after pain at child 40 feet. The flowers are in yellow colour birth, sprains and to treat swelling. The with pleasant fragrance which appears with a flowers of these plants are the rich sources glow. Generally flowering is observed of carotinoids 2. The chemical constituents during summer.1 of this plant are known to exhibit several Different parts of this tree are use biological activities such as anti microbial full to treat many diseases like stomatitis, activity, anti oxidant activity, cytotoxic insomnia, skin troubles, constipation, ring activity, anti glycemic activity, aldose worm. The flower extract is known to be a reductase inhibition activity, cardiotonic good sleep inducer and used in insomnia activity and choline esterase inhibitory treatment. Bark is used as a medicine for activity etc 3-8. The present objective of the dysentery and can also be used to prepare study is preparartion of the ethanolic extract 3949 Girish et al, J.

The test tube was shaken well and conc. sulphuric acid was added along the sides of the test tube. Formation of violet ring at the junction of two liquids. B. Fehling’s test: In a test tube 1 ml of Fehling’s A and 1 ml of Fehling’s B solutions were added. These mixed solutions were boiled Figure 1: Peltophorum pterocarpum tree for a minute. Then equal amount (2 ml) of test solution was added. Brick red precipitate was observed which confirmed the presence of carbohydrates. 2. Detection of Proteins 10: A.
