Mineral content of the rocket plant (Eruca sativa)

Abstract

Rocket (Eruca

Foliar application of zinc in the agronomic biofortification of arugula

“…Wu et al (2007), studying the tolerance of 158 materials from Brassica rapa L. at high concentrations of Zn, reported a low correlation between leaf iron and zinc contents in plants moderately and highly tolerant to the micronutrient. Neriman et al (2011), carrying out the nutritional characterization of 30 arugula samples from different locations, did not verify correlation between zinc and iron contents in the leaf. On the other hand, it is noted that with the highest dose of applied zinc, no Fe deficiency was observed, a factor that would also explain the lack of effect on chlorophyll a and b contents, since, according to Ebbs & Uchil (2008), iron deficiency due to high doses of Zn is one of the causes of the decrease in chlorophyll values.…”

Effect of heating processes on bioactive properties, phenolic components and mineral amounts of rocket (Eruca sativa Mill.) leaves

“…As a result, it has been reported that the evaluation of mineral content in plants is extremely important because the high mineral content of herbal products provides significant benefits in terms of human nutrition and health (Grusak & Dellapenna, 1999). Most of the macro (P, Ca and K) and micro elements (Fe, Zn, Mn) of our Rocket samples were higher than the results of Haag & Minami (1988), Hussain et al (2013), Barlas et al (2011) and Matev et al (2018). These differences may possibly be due to factors such as cultivar, growing conditions, plant nutrient content of the soil and irrigation.…”

“…In addition, it can be said that rocket is a good source of K, Ca, P and Mg, although the mineral contents of rocket partially decrease with drying. Barlas et al (2011) assessed 4.32% N, 0.25% P, 5.13% K, 2.95% Ca, 0.58% Mg,799.88 Na,350 Fe,5.36 Cu,40.58 Mn and 64.86 mg kg À1 Zn in rocket (E. sativa) leaves. Also, Haag & Minami (1988) found between 37 and 41 mg/100 g Mg in rocket leaves, while Bianco (1995) (Tripodi et al, 2017).…”

Also, Haag & Minami (1988) found between 37 and 41 mg/100 g Mg in rocket leaves, while Bianco (1995) reported that rocket leaves contain 46 mg/100 g Mg. Italian and Bulgarian E sativa contained 0.38 and 0.78 Ni, 8.37 and 3.58 Cu, 91.05 and 15.07 Zn, 144.50 and 353.50 mg kg −1 Mn, 47.26 and 43.56 g/kg K, respectively (Matev et al ., 2018).…”

“…), a green leafy vegetable belonging to the Brassicaceae family and containing significant levels of bioactive active ingredients, is widely known as rucola, arugula, roka (in Turkish) and roquette. Rocket is a very popular vegetable in Mediterranean countries, Europe, North America, Argentina and South Africa, as well as is grown in Central and Western Asia to obtain oil from its seed (Yaniv et al ., 1998; Barlas et al ., 2011; Matev et al ., 2018). Rocket is a wild and cultivated plant known in Mediterranean countries since the Roman Empire.…”
