Abstract

Suspended callus cultures of Nicotiana tabacum treated with commercial cellulase (ex Trichoderma viride) incorporated sodium [1, 2-13C2]acetate to give a 13C-enrichment of ca 1.6% of the carbon content of debneyol. 13C NMR data indicated that the angular methyl group in debneyol arises by migration from the C-10 position of a eudesmane-type intermediate. 13C enrichments of 0.8% and 1.3% respectively were observed in phytuberol and phytuberin isolated from the cultures.
