bioactive compounds belonging to lavonoids, alkaloids, tannins, phenols,
saponins, phytosteroids, and glycosides. The bioactive compounds isolated
from this species include nuciferin, nornuciferin, nelumborosides A and B,
nelumstemine, dotriacontane, roemerin, liensinine, referine, lotusine, liri-
odenine, asimilobin, and pronuciferine. These compounds, apart from other
activities, have also shown inhibitory actions on the secretion, aggregation,
and suppression of platelets
in vitro
. The lavonoids of its leaf extract have
been reported to attenuate body lipid accumulation and prevent obesity. The
compound (S)-armepavine is a potential therapeutic agent for treating auto-
immune crescentic glomerulonephritis (AcGN). In traditional medicines, its
leaves are used for treating sunstroke, diarrhea, dysentery, fever, dizziness,
and blood vomiting. Its fruit decoction is used for treating fever, heart prob-
lems, and for blackening hair. The plant extract is also used as an antidote
for smallpox and for treating cholera, worm infection, and intermittent fever.
