Isolation of Clivacetine from Clivia miniata REGEL. (Amaryllidaceae)

Abstract

Clivia miniata REGEL. (Amaryllidaceae) was found to contain a novel alkaloid, clivacetine (2), as well as lycorine (3), clivatine (4), clivimine (5), and clivonine (6). Clivacetine was identified as O-acetoacetylclivonine (2) and has an interesting structure from a biogenetic viewpoint, since it is a possible biosynthetic precursor of clivimine (5).
