-"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." \\

+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." \\

+"When compared to broccoli, lamb’s lettuce showed 3-fold higher total phenolic content as well as 4 to 22-fold
+higher free radical scavenging activity. It has been shown that sonication effects made some barley cell walls break down, leading to the release of some bound phenolic compounds although in the present work it was not observed significant differences between ultrasound and gyratory shaker for both vegetables. The results presented herein clearly demonstrate that lamb’s lettuce must be regarded as a very interesting source of polyphenols, and thus a potential health-promoting food." \\
