studies suggest that olive oil composition depends on both irrigation and the ripening process. In this sense, total polyphenol content is related to such factors, increasing olive oil bitterness and oil stability ( Motilva et al., 2000 ; Tovar et al

essential oil production is at flowering, when the oil content and preferred composition are the highest ( Topalov, 1962 ; Zheljazkov, 1998 ). Various basil species and cultivars provide essential oil with different compositions and aroma. The
