SUMMARY

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.
