Antioxidative activites and anti skin aging effects of radish(Raphanus sativus L. var. sativus) extracts were studied. The DPPH(1,1-Diphenyl-2-picrylhydrazal) inhibitory effects and CAT(Catalase) activities of hydrophilic radish extracts(DPPH 81.0%, CAT 175units/mg) were significantly higher than lipophilic radish extracts(DPPH 50.0%, CAT 45unitg/mg). But, SOD(superoxide dismutase) activities of hydrophilic radish extracts(SOD 81.3%) were lower than lipophilic radish extracts(SOD 92.3%) In the Bovine Achilles Tendon collagen treated with hydrophilic radish extracts and lipophilic radish extracts, the pyridinoline concentration of collagen were decreased, respectively.

Effects of triacontanol(TRIA) on several parameters of senescence including the changes of related enzyme activities were investigated in radish(Raphanus sativus L._ cotyledons developing in light. In senescing radish cotyledons, 1.0mg TRIA/1 retarded the degradation of chlorophyll content. Moreover, it depressed the increases of malondialdehyde and H2O2 contents compared to the control. Catalase and superoxide dismutase activities were highly maintained but the increase of peroxidase activity was inhibited remarkably under the TRIA application. These results suggested that TRIA participated in the regulation of senescence during the late part of cotyledon development where it delayed senescence through its action on free radical-associated enzymes and consequent metabolic turnover.

Aqueous extracts of Pinus rigida changed the electrophoretic patterns of total proteins and of hydrolytic enzymes such as peroxidase, esterase and amylase during the germination of radish (Raphanus sativus var. hortensis for. acanthiformis). When the extract treatment was finished, at the late stage of radish germination, aqueous extracts of P. rigida had suppressed the expression of 24 KD and 60 KD proteins. the extract induced new isozyme bands, indicating concomitant activity of peroxidases, esterase activities were stimulated in the cathodic region. The activity of amylase was enhanced by the extract.

Raphanus raphanistrum subsp. sativus (radish) powder contains several bioactive com- pounds and is widely used in the food industry. In this study, we examined the sensory attributes (taste, color, flavor, texture, and overall acceptability) of commercially available milk, yoghurt, and kefir containing different concentrations of R. raphanistrum subsp. sativus powder. The organoleptic characteristics of commercially available milk, yoghurt, and kefir was significantly different with respect to taste, flavor, color, texture, and overall acceptability in the treated group (1%, 2%. 3%. and 4%) compared to the control (0%; p<0.05). In addition, the scores of taste, flavor, color, texture, and overall acceptability decreased in proportion to the increase in amount of radish-powder in commercially available milk, yoghurt, and kefir. When 1% R. raphanistrum subsp. sativus powder was added to commercially available milk, yoghurt, and kefir, they showed good results in organoleptic characteristics compared to the control group. Therefore, our results could be used as the basis for estimating changes in organoleptic characteristics on supplementation of various dairy products with R. raphanistrum subsp. sativus.

The uranium removal capacity of radish sprouts (Raphanus sativus L.) in groundwater was calculated on the basis of the amount of uranium accumulated in the radish sprouts rather than the concentration in solution, of which process was very limited in previous studies. Continuous rhizofiltration clean-up system was designed to investigate the feasibility of radish sprouts, applying for uranium contaminated groundwater (U concentration: 110 μg/L) taken at Bugogdong, Busan. Six acrylic boxes (10 cm × 30 cm × 10 cm) were connected in a direct series for the continuous rhizofiltration system and 200 g of radish sprouts cultivars was placed in each box. The groundwater was flushed through the system for 48 hours at the constant rate of 5 mL/min. The rhizofiltration system was operated in the phytotron, of which conditions were at 25℃ temperature, 70% of relative humidity, 4,000 Lux illumination (16 hours/day) and 600 mg/L of CO₂ concentration. While 14.4 L of contaminated groundwater was treated, the uranium removal efficiency of the radish sprouts (1,200 g in wet weight) was 77.2% and their removal capacities ranged at 152.1 μg/g-239.7 μg/g (the average: 210.8 μg/g), suggesting that the radish sprouts belong to the group of hyper-accumulation species. After the experiment, the sum of U amounts accumulated in radish sprouts and remained in groundwater was 1,472.2 μg and the uranium recovery ratio of this rhizofiltration experiment was 92.9%. From the results, it was investigated that the radish sprouts can remove large amounts of uranium from contaminated groundwater in a short time (few days) because the fast growth rate and the high U accumulation adsorption capacity.
