Quercetin 3,3′,4′-tri-O-β-d-glucopyranosides from leaves of Eruca sativa (Mill.)

An approach to the phytochemical profiling of rocket [Eruca sativa (Mill.) Thell]

“…Thus, some works have shown that kaempferol di-O-glycoside was the major flavonoid in young Eruca leaves, 17 while other authors have reported kaempferol, isorhamnetin and quercetin as the predominant flavonoids. 21 Quercetin disinapoyl tri-O-glycoside has also been identified as predominant flavonoid in rocket accessions, 22 but it is worth mentioning that plants analysed were not E. sativa or they were an Italian ecotype with a very different leaf flavonoid profile to common commercially available E. sativa. 9 The variability observed in the phenolic profile between studies and plant varieties could be the result of multiple factors, including methodology (all reports used different approaches for extraction, chromatography, and quantification), sample characteristics and conditions, including variables such as growth.…”

Chemical composition, cooking quality, texture and consumer acceptance of pasta with Eruca vesicaria leaves

“…It is widely consumed fresh by human, as salad, or prepared as a steamed vegetable or used as a spice or food ingredient . Phytochemistry analyses revealed that rocket leaves present high content of human health-promoting compounds, mainly antioxidants (querc etine, polyglycosylated flavonoids, kaempferol) and glucosinolates with proven pharmaceutical properties (Weckerle et al, 2001;D'Antuono et al, 2008;Alqasoumi, 2010;Pasini et al, 2012). Phytochemistry analyses revealed that rocket leaves present high content of human health-promoting compounds, mainly antioxidants (querc etine, polyglycosylated flavonoids, kaempferol) and glucosinolates with proven pharmaceutical properties (Weckerle et al, 2001;D'Antuono et al, 2008;Alqasoumi, 2010;Pasini et al, 2012).…”

“…Thus, the development of new products like pasta with Eruca leaves can be a strategic area of the food industry. Eruca vesicaria leaves have a good nutritional quality with around 12.1% of total protein, 14% of fibres and a low content of fats 6.6% (Bukhsh et al, 2007), in addition to their glucosinolates and flavonoids contents (Weckerle et al, 2001;D'Antuono et al, 2008;Alqasoumi, 2010;Pasini et al, 2012). The green pasta is already in the market mainly with spinach in its formulation.…”

Glucosinolate profiles in the seeds, leaves and roots of rocket salad (Eruca sativaMill.) and anti-oxidative activities of intact plant powder and purified 4-methoxyglucobrassicin

“…1) and erucic acid contents (Ashraf and Noor 1992;Pita Villamil et al 2002). Most studies have focused on the effects of nitrate and ammonium nutrition on nitrate content in rocket (Bianco et al 1998;Santamaria and Gonnella 2001;Santamaria et al 1998;Santamaria et al 2002), as well as on its GSLs and their breakdown products, particularly the isothiocyanates (Bennett et al 2002;Cerny et al 1996;Jirovetz et al 2002;Miyazawa et al 2002;Weckerle et al 2001). When crushed, rocket leaves release a strong smell of horseradish combined with sesame seeds.…”
