Separation of flavonoids and anthocyanins from roses

Abstract

Aiming to find simple experimental activities, performed with easily accessible materials and less hazardous solvents, several studies were carried out and led to the development of a very simple and high visual impact liquid-liquid extraction technique, that enables the separation of anthocyanins and flavonoids from red roses petals. This sustainable activity may be implemented in Universities, allowing the teaching/learning of key concepts in practical classes of Organic Chemistry. It can be also used in Secondary Schools to demonstrate several concepts of Chemistry Curricula listed for Secondary Education.
