New Acylated Cyanogenic Diglycosides from Fruits of Anthemis cairica.

Three new cyanogenic diglycosides of the mandelonitrile series have been isolated from fruits of ANTHEMIS CAIRICA (Compositae) and their structures identified by degradation and spectral methods mainly (1)H-NMR, (13)C-NMR, FAB-MS. Minor compounds are 2-beta-primeverosyloxy-2-phenyl-2S-acetonitrile (epilucumin) and its 4''-p(beta-D-glucopyranosyloxyl-(E)cinnamate; the main compound is the 4''-p(beta-primeverosyloxy)-(E)cinnamate of epilucumin.
