WebThe PJ is particularly rich in punicalagin and ellagic acid. Punicalin and gallagic acid are also reported to be the main hydrolysable tannins of whole PJ. All of these hydrolyzable tannins have been known to be responsible for 92% of antioxidant capacity of whole PJ (Seeram et al., 2005; Tzulker et al., 2007 ).
