Abstract

Abstract:

To investigate the chemical components of the barks and twigs of Itoa orientalis. A new linear monoterpene glycoside named itoside O was isolated from the crude extract of Itoa orientalis together with 11 known compounds. The new compound was identified to be 3,7-dimethyl-1, 6-octadien-3, 10-dihydroxyl-10-O-α-L-arabinopyranosyl (1→6)-O-β-D-glucopyranoside by 1D and 2D NMR analysis, and all known compounds were isolated from this plant for the first time.

Key words: Itoa orientalis, Itoa orientalis, Flacourtiaceae, Flacourtiaceae, Itoside O, Itoside O, Monoterpene glycosides, Monoterpene glycosides, Chemical components, Chemical components
