The present study was carried out to investigate the biological activity of ethanol extracts from fermented Opuntia humifusa with 3 different mushroom mycelia: Phellinus linteus, Lentinula edodes, and Pleurotus ostreatus. Fermented Opuntia humifusa by Phellinus linteus (FOP) and Lentinula edodes (FOL) showed more DPPH and ABTS radical scavenging activities than non-fermented Opuntia humifusa (NFO) and fermented Opuntia humifusa by Pleurotus ostreatus (FOPO). At a concentration of 250 ppm, the ABTS radical scavenging activities of the FOP and FOL were similar to that of BHA, a synthetic antioxidant. The total polyphenol content had a similar tendency to that of the radical scavenging activity. However, the flavonoid content was increased in the order of NFO, FOL, FOPO, and FOP. At all concentrations, the tyrosinase inhibitory activity of FOP and FOPO were significantly higher than that of kojic acid. During adipocyte differentiation, NFO and FOL showed no significant difference in lipid accumulation in 3T3-L1 cells. FOP and FOPO showed a higher fat accumulation inhibitory effect than NFO and FOL. These results provide baseline data for Opuntia humifusa as a novel functional food.

Opuntia ficus-indica has traditionally been used in prevention and treatment of various diseases such as diabetes mellitus. The current study was performed to determine whether Opuntia ficus-indica is associated with diabetes. Diabetic rat models were induced with streptozotocin (STZ). This study divided rats into 1 day (short-term) and 4 consecutive weeks (long-terms) of daily administration. These groups were subdivided into four groups each other for assessment of blood glucose level as follows: Group 1, untreated rats given distilled water; Group 2, untreated rats given Opuntia ficus-indica; Group 3, STZ-induced diabetic rats given distilled water; Group 4, STZ-induced diabetic rats given Opuntia ficus-indica. Blood glucose level was measured for one day and four weeks. In addition, serum markers of alanine aminotransferase (ALT), aspartate transaminase (AST), cholesterol, and creatinine were determined, and total protein triglycerides were measured at four weeks. Blood glucose level was highest in both groups (Group 3 and Group 4) at 30 minutes and two weeks and gradually decreased in a time-dependent manner. The difference in blood glucose among the four groups was significant (p < 0.05). Additionally, the levels of ALT, AST and triglycerides were significantly decreased by Opuntia ficus-indica.

This study was carried out to clarify the addition effects of lentil and Opuntia ficus-indica instead of nitrite on storage stability for sausages. The antioxidant activity, acid value, peroxide value, volatile basic nitrogen and total aerobes were determined. As the concentration of lentils and Opuntia ficus-indica increased, total polyphenol and DPPH radical scavenging effects increased significantly. The F6 batch which had the maximum concentration of lentil and Opuntia ficus-indica, had the highest polyphenol value and DPPH radical scavenging effects. In addition, lentil and Opuntia ficus-indica supplementation lowered acidity, peroxide value and volatile basic nitrogen of sausages. Therefore, addition of lentil and Opuntia ficus-indica showed inhibition effects on lipid oxidation and protein deterioration of sausages. Also, Opuntia ficus-indica dropped pH, while lentil raised the pH. Bacterial counts didn't have an effect with the concentration of lentil and Opuntia ficus-indica on initial storage day. Overtime, the bacterial growth in the supplemented sausage group was less than the growth in no supplementation sausages. These results indicate that the addition of lentil and Opuntia ficus-indica increase antioxidative activity and inhibit lipid oxidation, protein deterioration and microbial growth. Lentil and Opuntia ficus-indica are useful materials in sausage production.

Hypoglycemic activity of Opuntia ficus-indica var. sabotan on alloxan or streptozotocin-induced diabetic mice was investigated. Fructus and folium of Opuntia ficus-indica vars. sabotan inhibited intestinal ${\alpha}-glucosidase$ of rats as well as glucose elevation in blood of normal mice, Opuntia ficus-indica var. sabotan exhibited inhibitory activities on streptozotocin-induced diabetic mice rather than on alloxan-induced diabetic mice loaded with maltose and sucrose. Its folium was more effective than its fructus. These results suggest that Opuntia ficus-indica var. sabotan might be effective on diabetic mellitus.

Opuntia cactus grows in the southern part of Korea, Geoje Island, Jeju Island, and South Coast. The flowers bloom around April to May of each year, and purple berries ripen around November to December. It has been widely used in home medicine since ancient times and it has great effects on blood circulation, detoxification, analgesia and antioxidant activity. In this study, we tried to demonstrate antioxidant, antidiabetic and antimicrobial activities of Opuntia monacantha Haw., and also grasp the value as a functional raw material. As a result, a strong antioxidative effect was confirmed by extracting taxifolin which is an antioxidative substance in Opuntia monacantha Haw. In the antidiabetic function test, a high level of antidiabetic function was confirmed when compared to that of using a commercially available diabetic drug. In addition, as a result of the antimicrobial effect measurement, it showed a strong antimicrobial activity on E.coli and Salmonella, and proved the excellent value of Opuntia manacantha Haw. as a functional ingredient.

Objective: The aim of this research was to evaluate the effect of different concentrate levels in diets based on cactus Opuntia Stricta (Haw.) Haw cladodes on the performance of lactating Girolando cows. Methods: The experiment involved 10 Girolando multiparous dairy cows at 512.6 kg of body weight (BW) and producing 13.2 kg milk/d, allocated into two 5×5 Latin squares. The experimental treatments consisted of control diet composed by cactus Nopalea cochenillifera. Salm-Dyck. cladodes (Nopalea), forage sorghum silage and concentrate at 20% on dry matter (DM) basis, and four concentrate levels diets (20%, 24%, 28%, and 32%) plus cactus Opuntia stricta (Haw.) Haw. cladodes (Opuntia) and forage sorghum silage. Results: Regarding cows fed control diet, the nutrients intake were greater than for cows fed with cactus Opuntia and concentrate. Regarding concentrate levels, intakes of DM, organic matter (OM), crude protein (CP), non-fiber carbohydrates (NFC), and total digestible nutrients of cows increased linearly. Organic matter, CP, and NDF digestibilities were similar in between to control diet and cactus Opuntia-based diets. The digestibility of NFC increased linearly when the concentrate was inserted. The N balance was the same for control diet and cactus Opuntia-based diets, irrespective the concentrate levels. Conclusion: For cows producing 14 kg/d with 3.5% of fat, it is recommended 32% of concentrate to be included in cactus Opuntia-based diets, and the increase in concentrate level promotes a linear increase in milk yield.

This study was performed to investigate the antiulcer effects of Opuntia dillenii Haw. on the stomach ulcer induced by restraint and water-immersion stress in rats. For this experiment, 48 male Sprague-Dawley strain were used. The experimental groups were divided into four: a control (C) and 3 Opuntia dillenii Haw. treatment groups (E-1, E-2, E-3). Each dose of Opuntia dillenii Haw. was 30 mg/kg bw (E-1), 60 mgfKg bw (E-2) and 120 mg/kg bw (E-3). The rats were allocated to each group by 12 and observed for 4 weeks. The results were as following: 1. The stomach surface pH in each group showed no significant difference, but the values of Opuntia dillenii Haw. treatment groups were higher than the value of the control group. 2. The gastric wall mucus was increased in all Opuntia dillenii Haw. treatment groups compared with the control group. Especially in E-1 difference was higher (p<0.05) and in E-2 difference was significantly higher (p<0.01). 3. At shear rate 11.25, 45.0, 90.0, $225\;sec^{-1}$, whole blood viscosity and plasma viscosity were measured. Most of the values of Opuntia dillenii Haw. treatment groups were low compared with that of the control group. At shear rate 90.0, $225\;sec^{-1}$ the values of whole blood viscosity in E-1 were significantly low (p<0.05) and at shear rate 11.25, $45.0\;sec^{-1}$, more significant (p<0.01). At shear rate 11.25, 45.0, 90.0, $225\;sec^{-1}$ the values of whole blood viscosity in E-2 were significantly low (p<0.01). At shear rate $90.0\;sec^{-1}$ the value of plasma viscosity in E-1 was significantly low (p<0.05) and at shear rate 90.0, $225\;sec^{-1}$ the values of plasma viscosity in E-2 we resignificantly low (p<0.01). 4. Less severe ulcers were obsered in Opuntia dillenii Haw. treatment groups than in the control group. Especially E-1 groups tissues had only slight ulcers and necrosis of tissue was not observed in this group. From the results of this study, it can be concluded that the oral administratio-n of Opuntia dillenii Haw. results in protection of stomach ulcer by stimulating the secretion of gastric mucus and improving the gastric mucosal microcirculation.
