Abstract:
Barringtonia acutangula Gaertn., (Samudraphal,Indian Oak), an important medicinal plant
of India is studied for its phytochemical and pharmacognostic biomarkers in both leaves
and bark. The leaves contained flavonols like 3’, 4’-diOMe quercetin, gossypetin and
3’-OMe gossypetin and quinones while the bark possessed only 8-oxygenated flavonols,
gossypetin and 3’-methyl ether and quinones. Gossypetin and its derivatives are the
distinct biomarkers here. The pharmacognostic markers of bark are two types of
rectangular cork cells, rows of square cells containing red deposits and very narrow
gelatinous fibres while those of leaves are single layered palisade wherein each cell
containing 3-4 chloroplasts, sclereids, absence of indumentum and flask shaped vascular
bundle.
