摘要：

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 C-13 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.
