Young Shoots of White and Red Headed Cabbages Like Novel Sources of Glucosinolates as Well as Antioxidative Substances

Abstract

Most literature data indicate that the diet rich in plant products reduces the risk of developing chronic non-communicable diseases and cancer. Brassica vegetables are almost exclusively synthesizing glucosinolates. Glucosinolates are higher in sprouts than in mature plants, being related to the activity of the specific myrosinase involved in the degradation of glucosinolates during developmental stages. This study compares the content of total glucosinolates with their profile and, rare in the literature, also with products of their degradation. Average amounts of total glucosinolates in young shoots of white and red headed cabbage were 26.23 µmol/g d.m. and 27.93 µmol/g d.m., respectively. In addition, antioxidative properties of 21-day-old shoots of white and red headed cabbage were assessed. The area of negative peaks after post-column derivatization with the ABTS reagent, indicating antioxidant activity of young red cabbage shoots, was 20185, compared to the value determined for young white cabbage shoots (3929). The results clearly indicate that, regardless of the vegetable species, young shoots of white and red headed cabbage can be an important source of bioactive substances in the diet, thus being an important element of cancer chemoprevention.

Distribution of Indolic Glucosinolates in Different Developmental Stages and Tissues of 13 Varieties of Cabbage (Brassica oleracea L. var. capitata)

“…In addition to assessing the accumulation of different cabbage pigments, this study also identified important defensive GLS involved in the defense responses against biotic and abiotic stresses, which have been reported to be widespread in cabbage and other cruciferous plants [37][38][39]. Among those GLS in different developmental stages, the content of GLS in the outer leaves showed dynamic fluctuations (Figure 6), which may be due to the influence of environmental factors on the accumulation of GLS in different developmental stages.…”

Progress of Research on Antioxidants and Carriers for Skin Wound Repair

“…fruit contains a variety of bioactive substances, such as polysaccharides, polyphenols, amino acids, nucleotides, triterpenoid acids, alkaloids and other nutrients, and has antioxidant and other physiological functions [35]. Cabbage contains glucosinolates, which not only has good antioxidant capacity but also plays an important role in cancer prevention [36]. Lotus root contains phenolic compounds, which have strong antioxidant and scavenging capacities against oxidative factors, so it will become a potential material for extracting antioxidants [37].…”

Basic Composition, Antioxidative Properties, and Selected Mineral Content of the Young Shoots of Nigella (Nigella sativa L.), Safflower (Carthamus tinctorius L.), and Camelina (Camelina sativa L.) at Different Stages of Vegetation

“…The growing popularity of young shoots is not only due to their nutritional importance, but also to their fascinating organoleptic characteristics. A number of factors, such as the rapid reduction of land sources, changes in lifestyle and eating habits, as well as the need for sustainable food production, have increased the interest in micro-scale vegetable production for the ready-to-eat meal market [8,9]. In the United States and European countries, microgreens have begun to appear in some grocery stores, mainly large supermarkets.…”
