Abstract
The effects of using two extracting solvents (methanol and ethanol 80%) on the extract yield, total phenol content and antioxidant activities of dried sumac fruits and leaves of dried rosemary and sage extracts had been studied. Generally higher crude extract yields were obtained using aqueous methanol as compared to the respective aqueous ethanol. Dried sumac fruits gave higher extract yields as compared with the extract yield of dried rosemary and sage leaves. Sage leaves gave higher amount of total phenol compounds as compared with the two other studied plants, also sage leaves extract gave better antioxidant activity through reducing power and bleaching of B-carotene tests compared with the antioxidant activities of sumac fruits and rosemary leaves.
