Chemical nature of ursolic acid:
Ursolic acid is a pentacyclic triterpenoid belonging to the A a A - amyrin group. It rarely occurs without oleanolic acid, which is a A A, - amyrin group triterpenoid. They may occur in the acid form or in glycoside form, which comprises of a triterpenoid aglycone linked to one or more sugar moieties. Ursolic acid and its derivatives are constituents of numerous plants which have diversified phytogenetic origin and taxonomic position. It has been isolated from the protective wax like coating of apples, pears, cranberries, prunes, and other fruits. Seaweeds are rich in ursolic acid derivatives. Some of the common plants containing ursolic acid are Tulsi, Rosemary, Periwinkle, Peppermint, Indian oleander and Eucalyptus.
