THE PHYTOCHEMISTRY OF ROSA-RUGOSA

The phytochemistry of Rosa rugosa is reviewed. The structures of the s econdary metabolites identified are listed and aspects of their chemis try are discussed. The metabolites are grouped according to structural classes and include hydrolysable tannins (contained in the leaves and petals), catechin derivatives (roots), flavonoids (leaves), 2-phenoxy chromones (leaves), monoterpenes (floral parts, leaves), sesquiterpene s (leaves, especially from glandular trichomes) and triterpenes (leave s and roots). The physiological significance of these metabolites is c onsidered from the perspective of assessing their contribution to the survival and adaptability of the species.
