Comparison of direct and indirect methods of measuring the precursors of beta-methyl-gamma-octalactone and their application to the analysis of Sessile oak wood.
Masson E, Baumes R, Puech JL. Masson E, et al. J Chromatogr A. 2001 Jan 5;905(1-2):183-91. doi: 10.1016/s0021-9673(00)00978-x. J Chromatogr A. 2001. PMID: 11206785
A new indirect method for measuring the level of beta-methyl-gamma-octalactone precursors in oak wood by GC-MS is described. This level is calculated from the difference between the amount of free beta-methyl-gamma-octalactone and the amount formed aft …
