5 NEW MONOTERPENE GLYCOSIDES AND OTHER COMPOUNDS FROM FOENICULI-FRUCTUS (FRUIT OF FOENICULUM-VULGARE MILLER)

Five new monoterpene glycosides, foeniculosides V, VI, VII, VIII and I X, were isolated from Foeniculi Fructus (fruit of Foeniculum vulgare M ILLER) along with seven known compounds, zizybeoside I, icaviside A(4) , syringin, sinapyl alcohol 1,3'-di-O-beta-D-glucopyranoside, adenosin e, threo-anethole glycol and erythro-anethole glycol. The structures o f foeniculosides V, VI, VII, VIII and IX were characterized as beta-D- glucopyranosides of (1S,2R,4S)-2,4-dihydroxy-1, 8-cineole-2-O-, (1R,4R ,6R)-4,6-dihydroxy-1,8-cineole-6-O-, (1R,4R,6R)-4,6-dihydroxy-1,8-cine ole-4-O-, (1S,2R,4R,6S)-2,6-dihydroxy-1,8-cineole-2-O- and (1S,2R,4S,5 R)-2,5-dihydroxy-1,8-cineole-2-O-, respectively, on the basis of chemi cal and spectroscopic data.
