Secoiridoid and flavonoid glycosides from Gonocaryum calleryanum

Abstract

The leaves of Gonocaryum calleryanum afforded four new secoiridoid glycosides acylated with 2,3-dihydroxy-2-methylbutanoic acid, three of which have a novel 10-membered dilactone-ring. From this plant, we also isolated a new flavonoid glycoside, apigenin 7-O-β-apiofuranosyl (1 → 6)-β-d-glucopyranoside, along with six known flavonoids and flavonoid glycosides, apigenin, apigenin-5,7-dimethyl ether, apigenin trimethyl ether, apigenin 7-O-glucoside, apigenin 7-O-neohesperidoside, and vitexin. The structure of the new glycosides was elucidated by chemical and spectral means. © 1995 Elsevier Science Ltd.
