-"Concentrates of blended lamb's lettuce obtained by combined high-vacuum distillation/solvent extraction were analysed by HRGC, HRGC-MS and, in part, HRGC-FTIR. In total, 103 aroma substances were identified for the first time. Qualitatively and quantitatively a number of 3-methylbutanoates and 2-phenethyl esters together with various volatile lipid cleavage products were predominant." \\

In total, 103 aroma substances were identified for the first time. Qualitatively and quantitatively a number of 3-methylbutanoates [2-phenethyl-3-methylbutanoate, (E)-2-hexenyl-3-methylbutanoate, benzyl 3-methyl-butanoate, methyl 3-methyl-butanoate] and 2-phenethyl esters together with various volatile lipid cleavage products [(E)-2-hexenal, (E)-2-hexenol, (Z)-3-hexenal] were predominant." \\

+"The advantages of this species are the short growing period of 60-90 days, low environmental requirements and high nutritional value of the crop. Previous analysis of lamb lettuce leaves for their food value
+showed the contents 6.6% of dry matter, 1.8% protein, 0.36% fat, 1.4% sugars, 1.5% dietary fiber, 3.9 mg carotene, 35 mg vitamin C (Maly, 1998). It is also recognized as a rich source of potassium (420mg/100 g of fresh matter), phosphorus (49 mg), calcium (35 mg) and iron (2 mg)... Plants harvested in the spring season
+contained higher levels of vitamin C [56-78mg%/34-56mg%], total sugars, K [5.0-6.8%/4.2-5.6%] and nitrates [0.20-0.25%/0.12-0.22%], whilst for those grown in autumn there were higher levels of dry matter, P and Mg [0.28-0.4%/0.41-0.45%]." \\

 "... lamb’s lettuce (Valerianella locusta) was chosen as a plant system, as it is rich in phenolic compounds and a steadily increasing consumer demand can be registered... Luteolin is one of the dominating compounds in lamb’s lettuce, while diosmetin appears in lesser amounts." \\
