Abstract:

Plan: A preliminary Pharmacognostical study on theleaves of Wrightia tinctoria (Roxb) R.Br.Methodology: The Wrightia tinctoria (Roxb) R.Br., leaves were collected dried and studied to determine various parameters of Pharmacognosticalstandards such as ash values, extractive values, phytochemical tests andmicroscopical characters of leaf powder. The shade dried powder and varioussolvent extracts (viz., methanol, 70% ethanol, aqueous, dichloromethane,chloroform, ethyl acetate and petroleum ether) have been analyzed for their phytoconstituentsandfluorescence characters. The methanolic extract was found to contain presenceof triterpenes.Outcome: The data generated for the Pharmacognostical evaluation on Wrightia tinctoria leaves may beuseful for establishing thestandardization protocols. The HPTLC analysis data indicated that the collectedWrightia tinctoria leaves contain 47.6mg of lupeol/ g of the total methanolicextract.
