摘要：

A new steroidal saponin named diurnoside 1 has been isolated from a methanolic extract of fresh leaves of Cestrum diurnum and the structure, (25R)-5alpha-spirostan-3beta-yl-4-O-{[2-O-(beta-D-glucopyranosyl)-beta-D-glucopyranosyl]-3-O-[beta-D-xylopyranosyl]-beta-D-glucopyranosyl)-beta-D-galactopyranoside, was determined by modern NMR techniques and chemical reactions.
