Volatile Components of Licorice Roots Produced in Different Countries

Abstract

Volatile components extracted from various Licorice Roots (Glycyrrhiza glabra L. var. glandulifera) by simultaneous distillation-extraction were analyzed and identified by capillary GC, GC-MS and kovats retention indices. Identified new components in Licorice Roots were 2 aldehydes, 2 ketones, 3 alcohols, 2 acids, 1 phenol, 6 hydrocarbons. It was shown that Licorice Roots contained hydrocarbons (32-59%), acids (30-56%) and phenols (6-18%). The yield of essential oils From Licorice Roots was 0.040-0.059% (W/W%).
