摘要

Betula utilis (family Betulaceae) is an important medicinal plant that grows in high altitudes of Himalayan region of India. The present study is aimed to determine the biochemical composition in the bark of Betula utilis using HPLC, HPTLC and GCMS methods. The optimization of solvent system for maximum extraction yield has been carried out. Total Phenolic Content (TPC), Total Flavonoid Content (TFC) and Antioxidant Activity (AA) were estimated in various solvent extracts. Maximum extractive yield (14.56%), TPC (14.47 mg/g), TFC (20.10 mg/g) in 75% ethanol and scavenging activity (92.89%) were found in 50% ethanol. Pentacyclic triterpenoids (betulin, tupeol, oleanolic acid, beta-sitosterol) were characterized and quantified using HPLC, HPTLC and GCMS found close within limits. Betulin was found maximum in ethanol.
