title: A new lipid and other constituents from the rhizomes of Nelumbo nucifera.
abstract: A new ursane triterpenoid ester, urs-12-en-3beta-O-9E,12E-octadecadienoate, was identified from the rhizomes of Nelumbo nucifera by spectral and chemical analyses along with the isolation of seven known compounds: palmitic acid, linoleic acid, 9E,12E,15E-octadecatrienoic acid, alpha-amyrin, beta-sitosterol, betulinic acid, and beta-sitosterol-3-O-glucoside.
