Cabbage (Brassica oleracea L. var. capitata) is one of the most important vegetables grown worldwide. Cabbage is valued for medicinal purposes in treating headaches, gout, diarrhea and peptic ulcers. The beneficial phytochemicals in cabbage help to activate and stabilize the body’s antioxidant and detoxification mechanisms that dismantle and eliminate cancer-producing substances. This seasonal vegetable can be made available for the consumers in off seasons also in the form of juice. The juice can be made shelf stable by using thermal treatment and various chemical additives. Therefore, the aim of the experiment was to compare the effect of different chemical additives namely Sodium benzoate, Potassium metabisulfite (KMS) and their combinations and the heat treatment, on the physicochemical, phytochemical parameters and antioxidant activity of Cabbage juice for a period of 6 months at room temperature at the regular intervals.The parameters like TS and TSS did not change significantly. The minimum increase in acidity was found in samples treated with combination of Sodium benzoate and Potassium metabisulfite. The color was best preserved by addition of KMS where the L value changed from 52.66 to 50.86 after 6 months. The ascorbic acid, total phenol content and antioxidant activity was best preserved by KMS with final values of 2.51 mg/100 g, 21.18 mg/100 g and 15.97 % respectively that were far better than the thermally treated samples with values 1.47 mg/100 g, 8.14 mg/100 g and 6.98 % respectively. Keeping in view all the parameters KMS was found to be the most appropriate agent for preservation.

Abstract. In this study, cytoprotective and antioxidant activities of Rosa canina (RC) and Salix alba (SA), medicinal plants, were studied on mouse primary splenocytes by comparing Controlled Differential Sieving process (CDSp), which is a novel green solvent-free process, versus a conventional technique, employing hydroethanolic extraction (HEE). Thus, preventive antioxidant activity of three plant powders of homogeneous particle sizes, 50–100 µm, 100–180 µm and 180–315 µm, dissolved directly in the cellular buffer, were compared to those of hydroethanolic (HE) extract, at 2 concentrations (250 and 500 µg/mL) in H2O2-treated spleen cells. Overall, compared to HE extract, the superfine powders, i. e., fractions < 180 µm, at the lowest concentration, resulted in greater reactive oxygen species (ROS) elimination, increased glutathione peroxidase (GPx) activity and lower malondialdehyde (MDA) production. Better antioxidant and preventive effects in pre-treated cells were found with the superfine powders for SA (i. e., 50–100 µm and 100–180 µm, both p < 0.001), and with the intermediate powder for RC (i. e., 100–180 µm, p < 0.05) versus HE extract. The activity levels of catalase (CAT) and superoxide dismutase (SOD) in pretreated splenocytes exposed to H2O2, albeit reduced, were near to those in unexposed cells, suggesting that pretreatment with the fine powders has relatively restored the normal levels of antioxidant-related enzymes. These findings supported that CDSp improved the biological activities of plants, avoiding the use of organic solvents and thus it could be a good alternative to conventional extraction techniques.
