Abstract
Abstract A new natural product, 3,4,8,9,10-pentahydroxy-dibenzo-[b,d]pyran-6-one was isolated from the flowers of Tamarix nilotica which also contains the known compound ellagic acid, 2,3,7,8-tetrahydroxy [1]benzopyrano[5,4,3-cde][1]benzopyran-5,10-dione. The structure of the new compound was determined by chemical and spectroscopic methods. The 13C MNR spectrum of ellagic acid was recorded and assigned.
