Abstract:
Earlier studies showed the presence of one alkaloid
from the flowers of Sph?ranthus indicus. 'lhe present
investigations on the flowers of this plant indicate the
presence of more alkaloids. Nine fractions were isolated
from the methanolic extract of flowers. Fraction 5 having
given the highest yield was further fractionated and two
pure compounds were obtained. Their physical constants were
determined (including UV, IR and Mass Spectra).
On the basis of these studies, two alkaloids have
been assigned tentative structures. These belong to the
cyclopeptide class of alkaloids.
