AROMATIC PLANTS AS FEED FOR GOATS IN AURÈS MOUNTAINS OF ALGERIA: CHARACTERIZATION OF VOLATILE AND PHENOLIC COMPOUNDS
Résumé
The aim of this work was to make an inventory of the aromatic plants pastured by goats in the
Aurès Mountains of Algeria and to characterize their volatile and phenolic compounds. In this context, a
survey was conducted among goat farmers in this region (department of Batna). Plant volatile compounds
were analyzed using HS-SPME/GC-MS and phenolic compounds using HPLC-DAD. According to the
results of the survey, twenty-nine (29) aromatic plants were identified as goats’ feed. The most cited ones
were Thymus algeriensis (96 %), Artemisia herba alba Asso (91 %), Rosmarinus officinalis L. (83 %),
Juniperus phoenica L. (80 %), Artemisia campestris L. (80 %), and Marrubium vulgare L. (70 %). The
major volatile compounds were -pinene (40 %), -thujone (38 %), trans-caryophyllene (31 %), -myrcene
(29 %), camphor (27 %), and -thujone (18 %). The most abundant phenolic compounds were flavonoids
(rutin, kaempferol-3-O-rutinoside, apigenin, hesperidin, isoquercitrin, and quercitrin), cinnamic acid
derivatives (chlorogenic acid, rosmarinic acid, caffeic acid, and ferulic acid), coumarines, and benzoic acid
derivatives. The present results indicate that aromatic plants from Aurès mountains of Algeria are rich in
phenolic compounds and could be offered as feed for goats.
