“…The content of intact aliphatic and indole glucosinolates in the inflorescences of broccoli cultivars Nubia, Naxos and Parthenon has also revealed differential response to salinity treatments (Dominguez Perles et al, 2011). In another work aimed to improve health promoting glucosinolates in edible sprouts suggested that glucoraphanin content decreased significantly, indole glucosinolates neoglucobrassicin, 4-hydroxyglucobrassicin and glucobrassicin were reported to decrease by 40 and 80 mm NaCl and increase by 100 mM NaCl application in 7d old broccoli sprouts germinated under different NaCl doses (Guo et al, 2013). Different from above mentioned studies, our work aimed to determine the influence of salinity on glucosinolates in broccoli seedlings representing earlier developmental stages.…”

Abstract. Broccoli (Brassica oleracea var. italica) synthesizes sulphur containing plant secondary metabolites known as glucosinolates that are often associated with bioactive properties upon hydrolysis. Glucosinolates are part of plant defence system and the glucosinolate content in plants is usually influenced by several factors including the genetic background of plants, developmental stage, environmental factors and soil conditions. The evaluation of factors affecting glucosinolate content in plants is important to obtain plants with improved bioactive properties. The objective of the present study was to determine the effect of NaCl (0, 40, 80, 100mM) on aliphatic and indole glucosinolate content of broccoli grown in greenhouse conditions. For this purpose, broccoli seedlings at 5-6 leaf were irrigated with 0 (control), 40mM, 80mM and 100mM NaCl. Glucosinolates were determined at three different time points (1, 3, 6 days upon treatment). According to the findings, the amount of individual and total aliphatics and indoles were lower at 40, 80 and 100mM NaCl applications compared to control plants determined at three different time points (P<0.001) suggesting the break down of glucosinolates due to stress conditions. The findings of the study revealed the glucosinolate profile and content of broccoli seedlings under saline conditions.

“…A possible explanation might be the NaCl-stimulation of other radical scavenging compounds biosynthesis, such as isothiocyanates and glucosinolates. Yuan et al (2010) found that the total glucosinolate contents in 5-and 7-day-old radish sprouts treated with 100 mM NaCl increased by 50% and 127%, respectively; Guo et al (2013) also, reported that the content of the isothiocyanate sulforaphane in 7-day-old broccoli sprouts treated with 100 mM NaCl was 2.1 times higher than in the control.…”

Sprouts are very rich in antioxidants (e.g. phenolic compounds) and their consumption is beneficial for humans' health. The sprouts' antioxidant properties are correlated to conditions of growth and maturity stage. The present study reveals the influence of maturity stage (5-, 7-and 9-day-old) and two sodium salts, NaCl and Na 2 SO 4 (10 mM and 100 mM) on the antioxidant capacity and total phenolic content of cauliflower and broccoli sprouts. The analysed sprouts' extracts were obtained in two phases, using ethanol 70% with 0.01% hydrochloric acid. In the case of cauliflower, the 7 days germination leads to the highest total phenolic content and radical scavenging capacity. Broccoli sprouts revealed the most enhanced DPPH radical scavenging capacity and total phenolic content at 5-day-old. The two sodium salts, generally, had positive effects on global antioxidant status. It is highlighted both for broccoli and cauliflower, the stimulating effect of 100 mM Na 2 SO 4 on the total phenolic content and soluble dry weight, but the DPPH radical scavenging activity was more important in the case of NaCl, than Na 2 SO 4 treatments, except for cauliflower sprouts treated with 100 mM Na 2 SO 4 . In conclusion, germination under adequate salt stress is a protocol to be considered in order to improve antioxidant properties of broccoli and cauliflower sprouts, despite the non-convenient effects on the germination and sprouts growth. Further researches are needed to optimize the level and time periods of such treatments.

“…The glucosinolate content varies depending on genetic and environmental factors, and is modulated by external signals such as sugar (Miao et al, 2013) and phytohormones (Yuan et al, 2009;Sun et al, 2012;Wang et al, 2012;Guo et al, 2013a;2013b;Huseby et al, 2013;Kim et al, 2013;Zang et al, 2015). Glucose is not only the basal carbon and energy source but also a signaling molecule having regulatory effects throughout the life cycle of plant (Sheen, 2014).…”

Glucosinolates, anthocyanins, total phenols, and vitamin C, as well as antioxidant capacity, were investigated in Chinese kale sprouts treated with both glucose and gibberellic acid (GA 3 ). The combination of 3% (0.03 g/ml) glucose and 5 μmol/L GA 3 treatment was effective in increasing glucosinolate content while glucose or GA 3 treatment alone did not influence significantly almost all individual glucosinolates or total glucosinolates. The total phenolic content and antioxidant activity of Chinese kale sprouts were enhanced by combined treatment with glucose and GA 3 , which could be useful in improving the main health-promoting compounds and antioxidant activity in Chinese kale sprouts.
