Stable isotope characterization of raspberry ketone extractive from Taxus baccata and obtained by oxydation of the accompanying alcohol (betuligenol)
The natural abundance (2)H nuclear magnetic resonance (NMR) characterization of raspberry ketone (1) extracted from himalayan Taxus baccata and of the accompanying (R) carbinol (2) is performed and compared with that of samples of 1 obtained from 2 by oxidation with Candida boidinii and CrO(3), respectively. The determination of the delta 13-C and/or delta 18-0 values of the above extractive products and of benzoic acid and 4-butylphenol, obtained from natural or synthetic 1, and of 4-phenylbutan-2-ol, prepared from extractive 2, allows a description of the labelling pattern of this set of products.
