Abstract: Medicinal plants have been used for antioxidants in the traditional medicine in the treatment of several diseases in humans. Plants antioxidants are composed of broad variety of different substances like ascorbic acid polyphenols or terpenoids. They perform several important functions in plants and humans. The trees chosen for the research is the guava - Psidium guajava, bael – Aegle marmelos and Jamun- Syzygium cumini trees. Antioxidants are known to revert oxidation process. Tree bark is a major waste product from paper pulp industries hence it is worth while to determine them. Total phenolic content was expressed as gallic acid equivalent by Folin Ciocalteu reagent method. Total Flavonoids content was determined by Aluminium Chloride Colorimertric method and expressed as quercetin equivalent. Alkaloids were expressed as atropine equivalent by Bromo Cresol Green Colorimetric test. Alkaloids have been found highest of all the antioxidants with specially high in the barks of Bael- Aegle marmelos and guava- Psidium sps. The phenols were lesser and flavonoids the least. The phenols and flavonoids are still higher in the bark of guava- Psidium sps than the other tree barks.
