Two mannose/glucose specific seed lectins were isolated from Parkia biglandulosa and Parkia roxburghii and were characterized w.r.t various physicochemical properties. Unlike other Parkia lectins a comparison of native and subunit molecular mass showed that both Parkia lectins were heterotetramers. Parkia biglandulosa lectin was found to be T-cell mitogen as revealed by IL-2 bioassay. These lectins showed anti-proliferative effect on two murine macrophage cancer cell lines i.e. P 388DI (50%) and J774 (70%). In addition Parkia roxburghii also inhibited proliferation of HB98 (65.47%), a B-cell hybridoma cell line.
