Comparative Evaluation of quality parameters in leaves, fruits and bark of Terminalia Sp

Terminalia sp belonging to Combretaceae family, is a tropical genus with 14 species in India. Out of that five species are used for praparation of medicine from ancient Ayurveda. Fruits of T. bellerica and T. chebula are the main ingredients in triphala churn while stem bark of T. arjuna, T. catappa and T. tomentosa have diuretic and cardiotonic properties. The present study was carried out for comparative evaluation of active phytoconstituents from Terminalia sp. Leaves, fruits and bark of five Terminalia sp were evaluated for total phenols, tannins and antioxidant potential. In case of leaves, fruitsand bark highest phenol content (10.31%, 22.38% & 12.35% resp), tannins (10.05%, 21.88% & 11.90 resp) and antioxidant potential (IC 50 - 15.46, 35.73 & 37.46 resp) was observed in T bellirica. Qualitative HPLC was also carried out to know the presence of phenolic/tannin specific markers.
