“…With a high variability in the content of glucosinolates reported within the genus Diplotaxis [36], D. tenuifolia belongs to the species cluster showing lower contents, with a range of 0.76-3.03 g kg −1 dry weight [27]. However, the total glucosinolate content is also influenced by a season effect (lower in June than September) and harvest succession [37]. Referring to specific compounds, perennial wall-rocket reportedly contains high amounts of glucosativin and lower levels of glucoerucin and glucoraphanin; the latter is more abundant in the flowers, while sinalbin is mostly contained in the roots [38][39][40].…”

“…Perennial wall-rocket has slightly higher values of dry matter (90 g kg −1 ) and fibre (9 g kg −1 ) than other salads, but similar nutrient content based on fresh weight, i.e., high levels of potassium (4.7 g kg −1 fresh product), calcium (3.1 g kg −1 ) and iron (52 mg kg −1 ) [57]. The total phenolic content in the plant extract has been estimated at 2.9 g kg −1 [58], the content of total carotenoids at 129 mg kg −1 , and that of ascorbic acid at 90 mg kg −1 [2,59,60], which has been shown to accumulate during plant growth [37]. Notably, the recommended daily intakes are 1.6-3.5 g for potassium, 0.4-1.0 g for calcium, 15 mg for iron, 0.3-1.0 mg retinol for vitamin A, and 30-60 mg for vitamin C [61].…”

Perennial wall-rocket (Diplotaxis tenuifolia (L.) D.C.) is a herbaceous plant belonging to the Brassicaceae with a cosmopolitan distribution. Traditionally harvested as a spontaneous herb, today it is a crop species of increasing importance after the diffusion of the ready-to-use salads in the vegetable retail markets. Besides relevance as a food crop, its consumption is prompted by consideration in the traditional medicine of several peoples in the native areas of the Mediterranean and western Asia based on recognized health beneficial effects. In fact, the leaves have notable nutritional properties related to their contents of glucosinolates and some antioxidant compounds, such as vitamin C and flavonoids, which entitle their dietary inclusion for the prevention of cancer and cardiovascular diseases. This paper provides an overview on aspects concerning the biology, crop management, nutritional properties, industrial processing and uses of perennial wall-rocket.

“…In studies on the effect of the harvest season and the growth stage on the vitamin C content in lamb's lettuce grown in the field, it was shown that when harvesting lamb's lettuce in early summer, young plants contained 54-57% more vitamin C than older plants. However, when harvesting plants at the end of summer, the vitamin C content in young plants was 9% lower than in older plants [54]. Thus, the patterns of changes in the content of ascorbic acid with the growth of the plant strongly depend on both the type of plant and the conditions of its growth.…”

Lamb’s lettuce (Valerianella locusta L. Laterr.) is a leafy green vegetable that is rich in various biological active compounds and is widely used in ready-to-eat salads. The cultivation conditions and growth stage could affect the secondary metabolism in plants and thereby modify their food value. In the present study, the effect of selenium (Se) application in various concentrations (5.0, 10.0, and 20.0 µM) on the contents of Se, phenolic compounds, vitamin C, carotenoids, chlorophylls, and antioxidant activity of hydrophilic and lipophilic extracts of lamb’s lettuce harvested at three growth stages (38, 52, and 66 days after sowing (DAS)) was studied. Se application significantly increased the Se concentration in the shoots (up to 124.4 μg g−1 dry weight), as well as the contents of chlorogenic acid, total flavonoids, total phenolics, ascorbic acid, chlorophyll b, and the antioxidant activity of hydrophilic and lipophilic extracts. A higher content of phenolic compounds and higher antioxidant activity of hydrophilic extracts was observed at the first growth stage (38 DAS). On the contrary, higher contents of lipophilic compounds (chlorophyll a, chlorophyll b, lutein, β-carotene) and higher antioxidant activity of lipophilic extracts were found for shoots harvested at later stages (52 and 66 DAS).

“…It is important to investigate many quality characteristics in a variety of leafy crops from a mix-use system point of view. There are some reports on the qualities of baby-leaf crops: some examples refer to the ascorbic acid concentrations in mizuna (Martínez-Sánchez et al, 2008), watercress (Martínez-Sánchez et al, 2008;Pignata et al, 2016), leaf lettuce (Kroggel et al, 2011;Samuolienė et al, 2012), rucola (Hall et al, 2015;Martínez-Sánchez et al, 2008;Nordmark et al, 2014), spinach (Morgen et al, 2012), corn salad (Nordmark et al, 2014), and komatsuna (Kroggel et al, 2011); the nitrate concentrations in green leaf lettuce (Aires et al, 2013), red leaf lettuce (Aires et al, 2013), watercress (Aires et al, 2013), rucola (Aires et al, 2013;Nicola et al, 2015), chard (Aires et al, 2013), corn salad (Aires et al, 2013;Fontana et al, 2004), garden cress (Nicola et al, 2015), spinach (Nicola et al, 2015), and bladder campion (Nicola et al, 2015); and the shelf lives of spinach (Conversa et al, 2014;Medina et al, 2012) and rucola (Nicola et al, 2003). However, fewer than 5 crops were checked in terms of quality measurements, even though yield research was carried out by using 10 to 20 crops (Borrelli et al, 2013;Fujime, 2005).…”

Baby-leaf vegetables" is a new category of leafy vegetables that are used in juvenile stage mixtures of different types of leafy vegetables. They include Brassicaceae, Asteraceae, Amaranthaceae, and other crops. The emergence periods, growing periods, total cultivation periods, from sowing to harvest, as well as the yields, SPAD values, ascorbic acid and nitrate concentrations, leaf characteristics and post-harvest shelf lives of 22 baby-leaf crops were investigated in April 2010 and April 2011. A principal component analysis, based on the total cultivation periods, yields, SPAD values, as well as the ascorbic acid and nitrate concentrations, indicated three main groups: Brassicaceae crops, which had short total cultivation periods and high ascorbic acid concentrations; Asteraceae crops (except for 'Italian Red' chicory), which had long total cultivation periods and low ascorbic acid concentrations; Amaranthaceae crops, which had comparatively high yields and low nitrate concentrations. 'Italian Red' chicory did not fall into any of these three groups. The yield had very limited effects on the grouping. The higher-yield crops tended to have more leaves and lower dry matter ratios, and the crops with higher SPAD values tended to have thicker leaves. An ideal assortment of baby-leaf crops was proposed based on an evaluation of the yield, external appearance and internal quality of each crop.
