Biotransformation of alpha-santonin by cell suspension cultures of five plants

Biotechnol Lett. 2005 Jun;27(11):793-7. doi: 10.1007/s10529-005-5800-0.

Abstract

Cell suspension cultures of five plants (Catharanthus roseus, Ginkgo biloba, Platycodon grandiflorum, Taxus cuspidata, Phytolacca asinosa) were employed to bioconvert the eudesmanolide compound, alpha-santonin. Reactions occurring were hydroxylation (C-1, C-11 and C-15), reduction of the double bond [1(2) or 3(4)], rearrangment of the eudesmanolide skeleton to a guaianolide skeleton and lactone-ring hydrolysis. Four new compounds were identified.
