Abstract
A new steroid was isolated from methanolic fraction of ethanol extract of seeds of Nymphaea stellata and was characterized as 24-methyl-cholesta-5-ene-3-ol-(23,24,29)-cyclopropane (1) and designated as Nymphasterol. The structure was elucidated on the basis of UV, IR, 1 D and 2 D NMR and Mass spectroscopy.
