The cyanogenic glycosides from different parts of Psydrax liuida (formerly Canthium huillense), Oxyanthus pyriformis subsp. pyriformis and O. speciosus subsp. gerrardii have been isolated and identified by means of their NMR data and chemical degradation. Psydrax liuida contains prunasin (2R-β-D-glucopyranosyloxyphenylacetonitrile; leaves), the new oxyanthin (2R-β-D-apio-D-furanosyl-(1→6)-β-D-glucopyranosyloxy-phenylacetonitrile; leaves, stems, fruits) and the 5''-benzoate of oxyanthin (leaves, stems). Oxyanthus pyriformis subsp. pyriformis contains prunasin, oxyanthin (leaves, stems, flowers, fruits) and amygdalin (2R-β-D-gentiobiosyloxyphenylacetonitrile; flowers). Oxyanthus speciosus subsp. gerrardii has holocalin (2R-β-D-glucopyranosyloxy-[3-hydroxyphenyl]acetonitrile) in leaves, stems and flowers.
