Baicalein was extracted from O. indicum leaves by conventional and non-conventional extraction methodologies viz. Maceration, Soxhlet assisted (SAE), Ultra-sonic assisted (UAE) and accelerated solvent extraction (ASE). Ethanol was optimized among the various organic solvents used for the maceration process. All the extracts were compared with respect to the percentage yield obtained and the concentration of the baicalein in the different extracts. Among all the extraction methodologies Accelerated solvent extraction method proved the best in terms of percentage yield and concentration of baicalein. This method showed a maximum percent yield about 8.21% of the total extracts and high concentration of about 1.481 ng of baicalein in the extracts respectively, using pre-optimized ethanol as an extraction solvent. The accelerated solvent extraction method was found to be more efficient for the extraction of baicalein from leaves of O. indicum.
