Triterpenes in the hexane extract of leaves of Olea europaea L.: analysis using 13C-NMR spectroscopy

Phytochem Anal. 2007 Jul-Aug;18(4):347-53. doi: 10.1002/pca.989.

Abstract

Two neutral triterpenes and a triterpene acid were identified and quantified directly, in the absence of any purification steps, in a precipitate obtained during the industrial extraction of the leaves of Olea europaea L. using 13C-NMR spectroscopy (spectrometer operating at 4.7 T equipped with a 10 mm probe). The method was optimised in order to reduce the duration of analysis with a routine NMR spectrometer. Together with long-chain linear compounds, erythrodiol, uvaol and oleanolic acid accounted for 27.3, 18.3 and 12.5% of the precipitate, respectively.
