Iridoid Glycosides from Escallonia Species

Abstract

Phytochemical study of Escallonia myrtoidea, E. illinita, E. alpina and E. pulverulenta led to the isolation of asperuloside and other C10-iridoid glycosides. From E. myrtoidea a new iridoid glycoside was isolated and identified as 6'0β-D-glucosylasperuloside by spectroscopic means. The findings are in accordance with the inclusion of Escallonia in the Saxifragaceae
