Various bioactive tannins, triterpenoids, terpenoids saponins, flavonoids, flavonoid glycosides have been isolated from the tree. Considering the possible deterioration of active components such as phenols and tannins during storage conditions, the present study was undertaken to evaluate different commonly available packaging materials.
