Magn Reson Chem. 2021 Nov;59(11):1165-1170. doi: 10.1002/mrc.5214. Epub 2021 Sep 7.

Abstract

The structure and complete nuclear magnetic resonance (NMR) assignments of orbifomitellic acid, a novel lanostane triterpene isolated from the fruiting bodies of a Gabonese Ganoderma orbiforme (Polyporaceae), are reported. Within the vast catalogue of lanostanes documented from Ganoderma spp., orbifomitellic acid is the first disclosing a -COOH group at C-4.

Keywords: 13C NMR; 1H NMR; Ganoderma orbiforme; NMR; Polyporaceae; lanostane; triterpene.
