Résumé
Extraction of carotenoids from biological matrices and quantifications remains a difficult task. Accelerated solvent extraction was used as an efficient extraction process for carotenoids extraction from three fruits cultivated in Tunisia: kaki (Diospyros kaki L.), peach (Prunus persica L.) and apricot (Prunus armeniaca L.). Based on a design of experiment (DoE) approach, and using a binary solvent consisting of methanol and tetrahydrofuran, we could identify the best extraction conditions as being 40 degrees C, 20:80 (v:v) methanol/tetrahydrofuran and 5min of extraction time. Surprisingly and likely due to the high extraction pressure used (103bars), these conditions appeared to be the best ones both for extracting xanthophylls such as lutein, zeaxanthin or beta-cryptoxanthin and carotenes such as beta-carotene, which present quite different polarities. Twelve surface responses were generated for lutein, zeaxanthin, beta-cryptoxanthin and beta-carotene in kaki, peach and apricot. Further LC-MS analysis allowed comparisons in carotenoids profiles between the fruits.
