摘要：

We describe a methodology which allows identification and quantitation of individual triterpenes in natural mixtures. using the computer-aided analysis of their C-13 NMR spectra, without previous separation. The analytical procedure was validated on artificial mixtures and applied to authentic extracts of cork. Identification of triterpenes was possible with the use of either reference spectra recorded in our laboratory or literature data.
