New nitrogen-containing compounds in Lilium candidum L.

Abstract

1-(3’-Methyl-2’-oxo-5’-pyrrolidinyl)-3-methyl-3-pyrrolin-2-one, 1-(2’-oxo-5’-pyrrolidinyl)-3-meth-yl-3-pyrrolin-2-one and 1-(3’-methyl-2’-oxo-5’-pyrrolidinyl)-5-hydroxy-3-methyl-3-pyrrolin-2-one were isolated from petals of Lilium candidum L.(Liliaceae). Presence of these substances, obtained by column chromatography of the extract on silica gel, has not been reported in any plant material as yet; their structures were adduced from spectral data.
