Four anthocyanins, cyanidin 3-O-(200-(5000-(E-p-coumaroyl)-b-apiofuranosyl)-b-xylopyranoside)-5-O-bglucopyranoside,
cyanidin 3-O-(200-(5000-(E-p-coumaroyl)-b-apiofuranosyl)-b-xylopyranoside), cyanidin
3-O-(200-(5000-(E-caffeoyl)-b-apiofuranosyl)-b-xylopyranoside) and cyanidin 3-O-(200-(5000-(E-feroyl)-bapiofuranosyl)-
b-xylopyranoside) were isolated from leaves of African milk bush, (Synadenium grantii
Hook, Euphorbiaceae) together with the known cyanidin 3-O-b-xylopyranoside-5-O-b-glucopyranoside
and cyanidin 3-O-b-xyloside. The four former pigments are the first reported anthocyanins containing
the monosaccharide apiose, and the three 5000-cinnamoyl derivative-200-(b-apiosyl)-b-xyloside subunits
have previously not been reported for any compound.
