Abstract: It is known that the consumption of fruit, vegetables and other plant products is beneficial for our health due to the presence of several bioactive compounds. Most of these compounds are aromatic secondary metabolites, which are synthesized in plants during their normal growth and under stressful circumstances [1]. They possess several activities, such as antioxidant, antibacterial, antifungal etc. [2-7]. In general, the by-products of many fruits represent a source of sugars, minerals, organic acids, anthocyanins and phenolic compounds. The last two categories are known for their important biological activities, including antioxidant, antibacterial, cardio-protective, anti-carcinogenic and anti-mutagenic effects [8-10]. Synthetic antioxidants were used in the food, pharmaceutical and cosmetics industry, over the past decades, in order to maintain the stability and quality of each product, over a longer period of time, though toxicity and some other side effects that observed, led researchers towards recovery and isolation of bioactive compounds from natural resources [11].
