A spirostanol glycoside from Cestrum nocturnum.
A new steroidal saponin named nocturnoside A has been isolated from the methanolic extract of the fresh leaves of Cestrum nocturnum and has been characterized by 13C NMR spectroscopy to be 3-O-[beta-D-glucopyranosyl(1----3)-beta-D-glucopyranosyl(1----2)-beta-D- glucopyranosyl((3----1)-beta-D-xylopyranosyl)(1----4)-beta-D- galactopyranosyl) (25R)-spirost-5-ene-2 alpha,3 beta-diol.
