Determination of Selected Biologically Active Substances on Lavender Grown in the Czech Republic

Abstract

Lavender as a herb and the lavender essential oil have a wide range of biological effects. They have been used in cosmetics and medicinal products since the times of ancient Greece and Rome. Nowadays, there is a wide range of products containing lavender on the market, either as such (lavender tea or biscuits or other snacks with lavender flowers) or containing lavender essential oil or aqueous solutions of lavender (cosmetics, drugstore goods, food or pharmaceutical preparations). This work focuses on the determination of the essential oil content, the representation of volatile substances and the determination of total phenols and flavonoids in samples of medicinal lavender from the Levandulové údolí and bought in the Czech shops.
