A new indolizinone from Polygonatum kingianum

Planta Med. 2003 Nov;69(11):1066-8. doi: 10.1055/s-2003-45160.

Abstract

A new indolizinone, namely kinganone (1) together with 3-ethoxymethyl-5,6,7,8-tetrahydro-8-indolizinone (2) and isomucronulatol (3) were isolated from the rhizome of Polygonatum kingianum. Their structures were elucidated mainly on the basis of spectral data. Indolizinones 1 and 2 showed weak antibacterial and antifungal activities when compared to rifampicin and amphotericin, respectively, in the agar diffusion assay.
