  • In this paper, we made sausages which included 1% black garlic extracts at $15^{\circ}Bx$ mixed with 0.3% dried powders of Curcuma longa L. (ST1), Opuntia ficus-indica var. saboten (ST2), Asparagus ocinals L. (ST3) and Aloe vera (ST4), respectively, and evaluated the quality of the sausage by instrumental analysis and sensory evaluation. The sausages were stored at $8^{\circ}C$ for 4 weeks. In terms of color intensity, ST2 provided the highest lightness (L) and redness (a), while the yellowness (b) was the highest in ST3. In the initial duration, the control group of sausage showed the highest texture measurement. ST4 had the lowest pH level (highest acidity). These outcomes decreased as the storage time became longer. In the initial storage duration, the ST4 had the highest total sugar content ($17.64{\pm}0.92mg/100g$), and this increased with longer storage duration. Since the contents of TBARS for the proposed sausages had been incremented, the initial contents were generally lower than those of the control sausages. The ABTS radical scavenging activity was performed as $89.11{\pm}0.66{\sim}99.22{\pm}0.09%$ at the $1000{\mu}g/mL$ level during the initial day of storage. To conclude, the sausages supplemented the black garlic with the proposed dried powders have a high chance of being a suitable commercial product for both customs and marketing eld.

  • Functional properties of Cheonnyuncho fruit paste (CFP) were enhanced by fermentation, using Leuconostoc mesenteroides SM. The stability of CFP pigment was maintained and microorganisms in crude CFP were sterilized by heating at $80^{\circ}C$ for 30 min. The production of dextran in CFP was increased by increasing the fermentation time and sugar content, resulting in an increase of consistency. The CFP fermented with 20% sucrose contained 4.8% mucilage after fermentation for 2 days. In particular, the production of mucilage was greatly enhanced by fortification with 3% sodium citrate in CFP, resulting in mucilage production of 7%. In addition, the viscous modulus of fermented CFP showed a greater increase than that of the elastic modulus. Thus, it was concluded that CFP fermented by L. mesenteroides SM can be fortified with functional ingredients, such as mucilage and probiotics, with enhanced rheological properties. Therefore fermented CFP can be utilized as the functional ingredients for functional foods.

  • The color stability of betacyanins and effects of antioxidants from Opuntia dillenii Haw were determined in the fruit juice at temperature up to $90^{\circ}C$. The absorption maxima of betacyanins occurred between 536 nm and 538 nm. When fruit juice was heated at $90^{\circ}C$ for various times, the red color gradually diminished and the absorption maxima slightly shifted toward uv region. The kinetic analysis of the data obtained indicated that the discoloration for betacyanins obeyed first order reaction pattern, when the thermal stability test was performed at $50{\sim}90^{\circ}C$. And the rate constant increased from $1.56{\times}10^{-3}/min\;to\;71.91{\times}10^{-3}/min$ with the half-life decreasing from 444.23 min to 9.64 min. The results also indicated that the thermal stability of pigment decreased with increasing temperature. The energy of activation was 10.94 kcal/mole for the pigment. N-propyl gallate, L-cysteine, and ascorbic acid were added to cactus fruit juice at concentrations of $0.01{\sim}0.3%$ at different temperatures. Npropyl gallate and L-cysteine had a little antioxidant effect on betacyanins stability at $50^{\circ}C\;and\;70^{\circ}C$, whereas ascorbic acid had a great antioxidant effect with the half-life value of 2 to 10 times to that of the control.

  • Objective: To evaluate the effects of the carmine cochineal-resistant spineless cactus genotypes cv. Orelha de Elefante Mexicana (Opuntia) and Miúda (Nopalea) on the intake and digestibility of nutrients, ingestive behavior, performance, and ultrasound measurements of growing lambs. Methods: Thirty-six male (non-castrated) Santa Inês lambs were used, with an average age of 6 months and an initial average weight of 22.0±2.9 kg. They were distributed in a completely randomized design with 3 treatments (Tifton hay, Nopalea and Opuntia) and 12 replications, using initial weight as a covariate. The experimental period was 86 days, with the first 30 days used for the adaptation of the animals to the facilities, diets and management, and the remaining 56 days used for evaluation and data collection. Results: The intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TC), non-fibrous carbohydrates (NFC), and total digestible nutrients (TDN) showed a significant difference (p<0.05) as a function of the diets, with the Nopalea treatment (p<0.05) increasing DM intake (g/kg and % body weight [BW]), CP, TDN, and TC digestibility, whereas the Tifton hay diet led to a high (p<0.001) neutral detergent fiber corrected for ash and protein (NDFap) g/d intake, NDFap (BW %) and digestibility of said nutrient. There was no effect of treatments (p>0.05) on feeding time, however, rumination time and total chewing time were higher (p<0.05) for animals fed Tifton hay. The performance of the animals was similar (p>0.05). For the ultrasound measurements, Nopalea promoted an increase in the final loin eye area, compared to Tifton hay. Conclusion: The use of spineless cactus variety Miúda leads to the greater intake and digestibility of nutrients. The evaluated carmine cochineal-resistant spineless cactus genotypes are alternatives for semi-arid regions as they do not negatively affect the performance of growing lambs.

  • Effect of Cheonnyuncho extract on the liver injury of rats treated carbon tetrachloride $(CCl_4)$ was studied. Cheonnyuncho extract was administerd at dose of 0.5 and 1 g/kg/day, p.o. for 2 weeks. $CCl_4$ was treated at dose of $0.5\;mL/kg$, i.p. 3 hours later from the last pretreatment of Cheonnyuncho extract. Administration of Cheonnyuncho extract at a dose of 1 g/kg decreased serum AST, ALT and ALP activities by 36, 41, and 22% respectively compared to $CCl_4$ treatment group. Increased lipid peroxidation and decreased SOD and GST activities were also recovered by pretreatment of Chonnyuncho extract in liver of rats. These results suggest that Cheonnyuncho extract has hepatoprotective effect against liver injury.

  • This study was designed to investigate the effect of cactus (Opuntia ficus-indica var. saboten) extracts on the intestinal bacteria, antioxidative activity and angiotensin -I-converting enzyme(ACE) inhibitory activity. The antimicrobial activities were measured using the 96well-plate method and disc plate method with concentration of 20mg of cactus extract. The stem extract of cactus was inhibitory against Eubacterium limosum, Clostridium perfringens, C. butyricum, C. difficile and Staphylococcus aureus, but was not inhibitory against Bacteroides fragilis, Bifidobacterium bifidum, Lactobacillus acidophilis, Streptococcus thermophilus. The fruit extract of cactus showed no inhibition against Bacteroides fragilis, Bifidobacterium bifidum, Lactobacillus acidophilis, and Streptococcus thermophilis. Their inhibitory activities were not reduced after heat and pH treatment. Antioxidative effects of cactus extracts showed high total polyphenol and flavonoid contents and high activity against free radical DPPH. The stem and fruit extract of cactus showed strong ACE inhibitory activities of 88.8% and 69.2%, respectively. In conclusion cactus (Opuntia ficus-indica var. saboten) extract might be utilized as a functional food material to control intestinal microflora.

  • Opuntia ficus-indicavar. saboten Makino (Cactaceae) is a tropical or subtropical plant that has been widely used as folk medicine for the treatment of diabetes, asthma, burn, edema and gastritis. The purposes of the present study were to identify antioxidant constituents from fruits and stems of the plant cultivated in Cheju island, Korea, and examine their in vitro neuroprotective activities. Using a chromatographic fractionation method, ten chemical constituents were isolated from ethyl acetate extracts. By means of chemical and spectroscopic methods, those were identified as eight flavonoids such as kaempherol (a), quercetin (b), kaempferol 3-methyl ether (c), quercetin 3-methyl ether (d), narcissin (e), dihydrokaernpferol (f), dihydroquercetin (g) and erioclictyol (h), and two terpenoids such as 3-oxo-${\alpha}$-ionol-${\beta}$-d-glucopyranoside (i) and roseoside (j). Among the isolated compounds, comrounds c~e and h~j were those reported for the first titre from the plant. Compounds b, d and g showed DPPH free radical scavenging activities with IC$\sub$50/ values of 28, 19 and 31, ${\mu}$M respectively. Compounds d and g also inhibited iron-dependent lipid peroxidation with IC$\sub$50/ values of 2.4 and 3.5 ${\mu}$M. In a primary rat cortical neuronal cell culture system, compounds b, d and g inhibited xanthine/xanthine oxidase-induced (IC$\sub$50/ values of 18.2, 2.1 and 54.6 ${\mu}$M) and H$_2$O$_2$-induced (IC$\sub$50/ values of 13.6, 1.9 and 25.7 ${\mu}$M) cytotoxicities. In addition, compounds d and g inhibited NMDA-induced excitotoxicity by 21 and 33%, and only compound d inhibited growth factor withdrawal-induced apoptosis by 31% at a tested concentration of 3 ${\mu}$M. The results suggest that the antioxidant constituents with in vitroneuroprotective activities may serve as lead chemicals for the development of neuroprotective agent.

  • In fresh water fish hatcheries and farms, Saprolegniales often cause serious mortality to the fish and their eggs. Malachite green is an effective antifungal agent, but is carcinogenic to fish and humans. Alternative antifungal agents are needed. Presently, we tested various concentrations of MBT-01108 (Opuntia ficus-indica extracts) alone and in combination with bronopol, formalin and sodium chloride (MBT-01108 mixture) on in vitro mycelial growth and in vivo remediation of adult eel, Anguilla japonica, infected with Saprolegnia sp. and fertilized eggs of chum salmon, Oncorhynchus keta, to evaluate the compounds' antifungal efficacy on eyed-egg and hatching rates. MBT-Oll08 mixtures incorporating bronopol and formalin at respective concentrations of 50 and 30 parts per million (ppm), and 100 and 20 ppm were most effective in controlling Saprolegnia in vitro and in vivo (P<0.05). Repeated daily exposures to 50 ppm and 100 ppm MBT-01108 were more effective than exposure every 2-3 days post-fertilization for the inhibition of Saprolegnia infection of rainbow trout, Oncorhynchus mykiss eggs as compared with control (0 ppm).

  • We investigated whether the combination of phytochemicals and acetic acid in the form of fruit vinegar provides an additive effect on changes of mRNA levels related to fatty acid oxidation in human hepatocyte (HepG2). Among the seven fruit vinegars (Rubuscoreanus, Opuntia, blueberry, cherry, red ginseng, mulberry, and pomegranate) studied, treatment of HepG2 with pomegranate vinegar (PV) at concentrations containing 1 mM acetic acid showed the highest in vitro potentiating effect on the mRNA expression levels of peroxisome proliferator-activated receptor ${\alpha}$, carnitinepalmitoyl transferase-1, and acyl-CoA oxidase compared to the control group (P < 0.05). Reversed-phase liquid chromatography in combination with quadrupole time-of-flight mass spectrometry analysis revealed four potential compounds (punicalagin B, ellagic acid, and two unidentified compounds) responsible for altered gene expression in HepG2 cells treated with PV as compared with the others. Further investigations are warranted to determine if drinking PV beverages may help to maintain a healthy body weight in overweight subjects.

  • Epiphytic communities on marine plants of Seychelles (Indian Ocean Island group associated with East Africa) were investigated in January - March of 1989 during the $15^{th}$ biological voyage of the research vessel cademic Alexander Nesmeyanov. A seagrass species, Thalassodendron ciliatum, and macroalgae (Sargassum spp. and Halimeda spp.) were tested for host substrates and biomass of their dominant epiphytes were assessed. Also, in order to understand the effect of shading and nutrient filtering by epiphytes, two series of photosynthetic rates were compared for Th. ciliatum host leaves having 10% and no epiphytes. Total of 84 species of algae and main taxons of benthic animals were identified from three different host plants. An average biomass of the epiphytes on Th. cihiatum was $184.6g\;kg^{-1}$ and dominant species were green alga Halimeda opuntia, red algae Dictyurus occidentalis and Gelidiella myrioclada. These dominant species and their biomass were remarkably varied with depth increment. On Sargassum spp., an average biomass of the epiphytes was $0.18g\;kg^{-1}$ and the maximum biomass was never exceeded $0.16g\;kg^{-1}$. In the case of Halimeda spp. an average biomass of the epiphytes was $8.0g\;kg^{-1}$, and dominant species were Peyssonnelia dubyi, sponges and decapods. Photosynthetic rates of Th. ciliatum were significantly reduced in the leaves having 10% epiphytes (1.72 times lower, t=6.718, p<0.001).
