Assessment of aroma active compounds in cultivars of sea buckthorn

Abstract

The aim of the diploma thesis was the aroma active compounds assessment and sensory profile determination of various types of sea buckthorn (Hippopha rhamnoides L.). The theoretical part provides the detailed description of this plant, comprising the occurence, taxonomy, chemical composition and use. Experimental part summarizes the data obtained: identification and quantification of aroma compounds using the SPME – GC –FID and GC-MS method and evaluation of complete sensory profile. Various cultivars of sea buckthorn harvested in 2009-2012 were analysed. In total 23 various types of sea buckthorn were measured, 23 alcohols, 10 aldehydes, 11 esters, 14 ketones and 5 acids were found
