“…Recently, the production of radishes in Korea has reached approximately 1,168,000 tons per year [ 14 ]; more than 30% are grown in Jeju, and the cultivated area is continuously increasing. Radishes are an agricultural product with excellent nutritional value owing to their rich moisture and fiber content, and high content of vitamins A and C. In addition, they have traditionally been known to have various benefits, such as digestion-promoting, stomach-protecting, anti-inflammatory, anticancer, antioxidant, and hemostatic benefits [ 15 ]. These physiological effects can be observed in various functional ingredients such as glucosinolates [ 16 ], isothiocyanates, flavonoids, anthocyanins, alkaloids, saponins, and phenolic acids, which are abundant in radishes [ 17 ].…”

Hepatoprotective Effects of Radish (Raphanus sativus L.) on Acetaminophen-Induced Liver Damage via Inhibiting Oxidative Stress and Apoptosis

Alcohol and drug overdoses cause liver diseases such as cirrhosis, hepatitis, and liver cancer globally. In particular, an overdose of acetaminophen (APAP), which is generally used as an analgesic and antipyretic agent, is a major cause of acute hepatitis, and cases of APAP-induced liver damage are steadily increasing. Potential antioxidants may inhibit the generation of free radicals and prevent drug-induced liver damage. Among plant-derived natural materials, radishes (RJ) and turnips (RG) have anti-inflammatory, anticancer, and antioxidant properties due to the presence of functional ingredients, such as glucosinolate and isothiocyanate. Although various functions have been reported, in vivo studies on the antioxidant activity of radishes are insufficient. Therefore, we aim to evaluate the hepatoprotective effects of RG and RJ in APAP-induced liver-damaged mice. RG and RJ extracts markedly improved the histological status, such as inflammation and infiltration, of mice liver tissue, significantly decreased the levels of alanine transaminase, aspartate aminotransferase, and malondialdehyde, and significantly increased the levels of glutathione, superoxide dismutase and catalase in the APAP-induced liver-damaged mice. In addition, RG and RJ extracts significantly increased the expression of Nrf-2 and HO-1, which are antioxidative-related factors, and regulated the BAX and BCL-2, thereby showing anti-apoptosis activity. These results indicated that RG and RJ extracts protected mice against acute liver injury, attributed to a reduction in both oxidative stress and apoptosis. These findings have clinical implications for the use of RG and RJ extracts as potential natural candidates for developing hepatoprotective agents.

The photosynthesis, productivity, and mineral content of Chinese cabbage (Brassica campestris subsp. napus var. pekinensis cv. Detong) grown in different soil types on Jeju Island were investigated to develop soil-crop system management, with the goal of increasing crop productivity and quality. The soils were black volcanic ash soil (BS), very dark-brown volcanic ash soil (VDBS), and darkbrown non-volcanic ash soil (DBS). VDBS had a pH of 5.87, relatively close to the optimal pH range for Chinese cabbage cultivation, and slightly higher than the pH of BS and DBS; it had high contents of organic matter, available P2O5, and exchangeable cations (K, Ca, Mg, etc.). Growth of the cabbage head including height, diameter, fresh weight, leaf numbers, and leaf area were greater in Chinese cabbage grown in VDBS compared to BS or DBS. Root biomass was also greater in VDBS, although root length did not differ significantly among soil types. However, the soluble solid content was lower in VDBS than in BS or DBS. The maximum photochemical efficiency (F v /F m ) of photosystem II was slightly higher in VDBS and DBS, although it had stable values ≥ 0.8 in all three soil types. The SPAD values did not differ significantly and were ≥ 55 in all three soil types. The water-use efficiency (WUE) was slightly higher in VDBS, although the maximum photosynthetic rate (A) and dark respiration (R d ) did not differ among soil types. Of the mineral elements in cabbage head, total nitrogen was lower in VDBS than in BS and DBS. However, all macronutrients, except Mg, and micronutrient Cu were slightly higher in VDBS than in the other soil types. These results suggest that the relatively favorable soil conditions of VDBS (suboptimal pH, high mineral content, etc.) and high water-use efficiency of Chinese cabbage favor head growth and its nutritional value. VDBS was suitable for cultivating Chinese cabbage, considering productivity and product quality, such as its size, weight, and mineral content.

The growth and mineral content of garlic (Allium sativum L.) grown in different types of soil on Jeju Island, including black volcanic ash soil (BS), very dark-brown volcanic ash soil (VDBS), and dark-brown non-volcanic ash soil (DBS), were investigated to evaluate soil-crop system management, which is required to increase crop quality and productivity. Examining the soil physicochemical properties, the organic matter and total nitrogen contents were higher, while the available P2O5 and Mg contents were lower, in the volcanic ash soils than in the non-volcanic ash soil. During the growing stage, plant height and pseudo stem diameter were greater in garlic grown in VDBS or DBS compared to BS. At harvest time, bulb diameter and length, the number of cloves per bulb, and clove weight were greater in VDBS or DBS than in BS. In addition, in BS, shoot growth, bulb development, and clove differentiation were abnormal. The total N, P, K, Ca, Fe, Mn, Zn, and Cu contents in the bulbs were also higher in garlic grown in DBS or VDBS compared to BS. Specifically, the K, Mn, Zn, and Cu contents increased significantly in garlic grown in DBS. These results suggest that soil physicochemical properties affected the growth and development of garlic, and that the cloves should be grown in VDBS or DBS to increase the productivity of high-quality garlic with large, mineral-rich bulbs.
