Various literature proves the presence of numerous physiologically active phytochemicals viz., epicatechin, pterostilbene, propterol, marsupin, liquiritigenin, isoliquiritigenin, pterosupin, kinotannic acid, resorcinol, lupeol, and pterocarposide. The structures of a few important bioactives present in the plant. Out of the array of bioactives present, pterostilbene is the important bioactive which have been shown in the preclinical evaluations that it is responsible component for various biological activities associated with the plant and its preparations. Pterostilbene is a stilbenoid, it serves defensive phytoalexin role in the plants.
