EVALUATION OF PHENOL AND FLAVONOID CONTENT FROM AERIAL PARTS OF TECOMA STANS Research Article

Tecoma stans, from the family Bignoniaceae is an important medicinal plant. All parts are widely used in Ayurvedic system of medicines since ancient times. The present study was designed to investigate the content of phenols and flavonoids of various extracts of aerial parts of T. stans. All extracts revealed presence of phenol and flavonoid. The content of phenols and flavonoids of the investigated extracts differed as per the polarity of the solvents used. The content of total phenolics in the extract was determined spectrometrically according to the Folin-Ciocalteu procedure and calculated as catechol equivalent. The content of total flavonoids in the extract was determined and calculated as quercetin equivalent. Total phenolic compounds in ethanol extract is found to be 60.238 mg/g of extract calculated as Folin Ciocalteau equivalent (r2= 0.991). Total flavonoids in ethanol extract is found to be 6.545 mg/g calculated as quercetin equivalent (r2
