1 Dec 2014 carried out to evaluate the chemical composition of six essential oils of garlic, onion, leek, Chinese chive, shallot and chive as well as their antioxidant and antimicrobial activities. Foremost, the extractions of EO were optimized using turbo hydrodistillation, then they were analyzed for their possible.
Abstract. Onion (Allium cepa L.) is one of the economically important vegetable crops grown in Turkey. In this study, some physico-chemical and antioxidant properties, volatile compounds and fatty acid composition of ten different onion seeds were investigated. The fatty acid composition and volatile compounds.
