In this study the effect of four different drying techniques such as sun drying, oven drying, microwave drying and freeze drying of Terminalia arjuna bark have been studied. The effectiveness of different drying technique was measured in terms of phytochemical screening, total phenol, flavonoid, alkaloid and protein content. The antioxidant activity and antimicrobial activity were also determined. In phytochemical screening revealed the presence of alkaloid, triterpenoid, saponins, glycosides and phytosterols in different dried T. arjuna stem bark extract. The phenol, flavonoid, alkaloid and protein content were highest in freeze dried extract. Then it was followed by microwave, oven and sun dried extract. The antimicrobial activity and antioxidant activity were also found maximum in freeze dried T. arjuna stem bark. Among all sun drying was found most detrimental drying technique for bioactive components of T. arjuna stem bark and freeze drying was best for bioactive components of T. arjuna stem bark.
