COMPARATIVE THERMAL AND CHEMICAL-ANALYSIS OF 5 MEDITERRANEAN PLANTS

The comparative thermal and chemical study was done on five mediterran ean plants: Acacia dealbata, Quercus coccifera, Rosmarinus officinalis , Thymus vulgaris, Ulex parviflorus. Results were independent of the d rying way of samples (110 degrees C, 60 degrees C or lyophilisation). The correlation between the maximum decomposition rate at about 300 de grees C and the content of cellulose was confirmed. The samples cut on the same foot of Ulex parviflorus, in spring, produced, for the thorn s and sprigs, a minimum in cellulose content, and a maximum in lignine content. The results were inverse in winter.
