The Punicalin, with the CAS registry number 65995-64-4, is also known as 4,6-(S,S)-Gallagyl-D-glucose. This chemical's molecular formula is C₃₄H₂₂O₂₂ and molecular weight is 782.52. What's more, its systematic name is (10S,11R,12R,15R)-3,4,5,11,12,13,21,22,23,26,27,38,39-Tridecahydroxy-9,14,17,29,36-pentaoxaoctacyclo[29.8.0.02,7.010,15.019,24.025,34.028,33.032,37]nonatriaconta-1(39),2,4,6,19,21,23,25,27 ,31,33,37-dodecaene-8,18,30,35-tetrone. Punicalin is an ellagitannin. It can be found in Punica granatum (pomegranate) or in the leaves of Terminalia catappa, a plant used to treat dermatitis and hepatitis. It is also reported in Combretum glutinosum, all three species being Myrtales, the two last being Combretaceae. It is a highly active carbonic anhydrase inhibitor.
