Two American Vitis species, V. candicans and V. doaniana, were evaluated and compared for their anti-oxidant properties and anthocyanin profile. HPLC–MS and HPLC–NMR were used to identify the individual anthocyanins. The structures of 30 anthocyanins were identified by combining both techniques. In particular, new cis-p-coumaroyl isomers of peonidin and cyanidin were identified. Extract activities were evaluated by DPPH and ORAC methods. Both V. candicans and V. doaniana exerted anti-oxidant activities.
