Aegle marmelos L. commonly known as bael belongs to the family rutaceae, an important medicinal plant that is used in folk therapy. The fruit of this plant is a well-known remedy for diarrhea and is used in a number of formulations of traditional systems of medicine. Apart from the fruit, the leaves are the second most medicinally important part of this plant and are a part of several traditional formulations used in diabetes and ophthalmic disorder [1]. Since this plant has a great medicinal value it was thought worthwhile to the analyze the quality of its chemical characteristics. In the present investigation, the total phenolic flavonoid content was analyzed by a spectrophotometric method followed by the quantification of quercetin and umbelliferone using a HPTLC method. Since the plant was found to be a rich source of phenolic compounds, its antioxidant potential was also studied by DPPH method. The plant leaves were found to have a large variation in the content of secondary metabolites tested, hence a RAPD analysis was also performed to confirm the genetic diversity of different accessions.
