To improve the functionality of black garlic drinks, black garlic extract (5%) and five herb extracts (1%) were mixed in 70:30 (v/v) ratios as BHF1, and BHF2 was prepared using a 3X concentration of BHF1. After the black garlic and herb formulas (BHFs) were administered over the course of five weeks in rats by interval running training, the lipid profiles and the antioxidant enzyme activities were tested. The total phenolic content of the BHFs were significantly higher in BHF2 than they were in BHF1, and their antioxidant activities were dependent upon the total phenolic content. No significant difference was found in the total serum protein levels among the rats in the Ex-con group by interval running training and the rats in the BHFs-fed groups. However, the albumin level was significantly higher in the Ex-BHF2 to Ex-con group. AST and ALT activities significantly decreased in the BHFs-fed groups compared to the Ex-con group. In terms of changes in the serum lipid profiles, no significant difference was found between the specimens that underwent interval running training and those that did not undergo interval running training. Triglyceride levels, total cholesterol, LDL-C, and HTR levels in the serum were significantly decreased in the Ex-BHF2 to Ex-con group. No significant difference was found in the total lipid levels in the livers of the BHFs-fed groups and the Ex-con group. The triglyceride levels and total cholesterol levels in the Ex-BHF2 group were significantly lower compared to another group. Hepatic catalase activity was significantly increased in the Ex-BHF2 group, but SOD and GSH-px activities were significantly increased as the concentration of the BHF. The antioxidant enzyme activities by supplementation of BHFs increased; thus, three intakes of BHF each day could improve antioxidant status against different types of oxidative stress.

Physiological activities of the garlic extracts from eight different cultivating areas (three areas from Daejeong Jeju, four major cultivating areas (Danyang, Uiseong, Taean and Namhae) in Korea, and one imported from China) were investigated. Allicin was the highest in the garlic from Danyang (457 mg/100 g), and in the decreasing order of Uiseong (422), Taean (393), China (370), Jeju (334), Namhae (328). Total phenolic content (TPC) from Taean was the highest (3.77 mg GAE/g), while that from Namhae was the lowest (1.90). Average TPC (3.36 mg GAE/g) of the garlics from Daejeong Jeju was higher than that (2.87) from major cultivating areas in Korea. The highest integral antioxidative capacities of water-soluble substance were obtained from the garlics of Danyang ($3.24{\mu}mol$ ascorbic acid equivalents/g) and Daejeong Jeju (2.73), while the lowest ones were from Namhae (1.94) and Taean (1.67). The integral antioxidative capacities of lipid- soluble substance were the highest in the garlics from Namhae ($5.77{\mu}mol$ trolox equivalents/g of dry extract), Danyang (5.31) and Daejeong Jeju (5.29), while the lowest was from Taean (4.19). Average xanthine oxidase inhibition activity (31.1%) in the garlics from Daejeong Jeju was higher than that (23.2%) from major cultivating areas in Korea. All of the garlics showed the strong antimicrobial activity against S. aureus, and in the decreasing order of L. monocytogenes, S. Typhimurium, and E. coli. The garlics from Daejeong Jeju (specially from Alttre) showed the strongest antimicrobial activities against all four bacterial strains tested.
Physiological activities of hot water extracts of 10 commercial instant curry powders and 6 spices, were investigated. All spice extracts except ginger showed significant antioxidant activities on the autoxidation of linoleic curry acid (p<0.01). Antioxidant activities of clove and fennel were significantly higher than ${\alpha}-tocopherol$, instant curry powders, and other spices, Red pepper $(52.8{\pm}2.13%)$, clove, and coriander showed significant inhibitory activities against angiotensin-I-converting enzyme (p<0.001). Cytotoxic effects of instant curry powder and spices against human cancer cell lines were examined through MTT assay. Black pepper $(29.31{\pm}2.21%\;cytotoxic\;rate)$ and cardamon $(19.41{\pm}3.92%)$ were effective against MCF-7 (p<0.01), Clove $(42.92{\pm}5.57%)$ against HeLa (p<0.01). Ginger $(34.21{\pm}1.11%)$, cardamon, and black pepper against A172 (p<0.001), garlic $(82.88{\pm}0.53%)$ against SN12C (p<0.001), garlic $(71.63{\pm}0.38%)$, red pepper, ginger, fenugreek, SPC, cumin, and MPC against SNU-638 (p<0.001), and cassia $(82.84{\pm}16.92%)$ against A549 (p<0.001).
Objective: This study was conducted to examine the effects of a mixture of pinecone oil, garlic, and brown seaweed extracts (PGBE) on milk production traits as well as physiological and ethological parameters in Holstein cows during the summer season (24 May to 03 July 2015, Korea). Methods: Among the extract combinations tested, we found that the level of 2,2'-azino-bis (3-ethylberzothiazoline-6-sulphonic acid) cation radical scavenging activity of the 0.16% PBGE complex at ratio of 1:1:1 (vol/vol) was comparable to that of the control (ascorbic acid; 1 mg/mL). Additionally, the PBGE complex reduced lipopolysaccharide-induced COX-2 expression in bovine mammary epithelial cells. Based on these findings, 40 lactating Holstein cows were used to measure the effects of PBGE complex at ratio of 1:1:1 (vol/vol) on milk production, immune response, metabolites, and behavior patterns by dividing the cows into two groups fed diets containing PGBE complex (n = 20; 0.016%/kg feed dry matter basis) or not containing PGBE complex (control, n = 20) for 40 d. Results: Results showed that PGBE complex did not influence milk composition, eating and ear surface temperature patterns, immune response, or metabolic parameters but promoted average milk yield throughout the experimental period. Additionally, a tendency of higher total antioxidant capacity and glutathione in the PGBE group was observed compared to the those in the control. When the temperature-humidity index (THI) exceeded 72 (average THI = 73.8), PGBE complex-fed cows experiencing heat stress showed increased milk yield and a tendency of increased rumination compared to the control. Conclusion: We suggest that incorporation of a combined mixture of 0.016% PGBE (1:1:1 ratio, vol/vol) to diet has the potential to improve milk yield and health status of cows under mild to moderate heat stress, denoting that it might be useful as an alternative anti-stressor in the diet of dairy cows under hot conditions.
Biological effect of aqueous extracts of 12 plants which showed superoxide dismutase (SOD)-like activity in vitro was evaluated using Drosophila melanogaster. Survival percentage of the flies was a criterion of effect when the flies were exported to paraquat, which generated superoxide anion radical in vivo. When flies were co-administered with paraquat and aqueous extracts of garlic, lettuce, kiwi, and nameko, they showed no defensive effect against of oxygen toxicity. If flies were exposed to 60 mM paraquat after adaptation to feed containing plant extracts with SOD-like activity for 10 days, however, survival percentage of flies fed with phytochemicals was $35{\sim}63%$ while that percentage of flies fed without phytochemical was only 11%. This result indicated that adaptation of flies to plant extracts with SOD-like activity could prevent the flies from oxidative injury. On the other hand, lettuce, kiwi, nameko, onion, persimmon, fern brake and cauliflower showed a reparative effect on an oxidative stress. Dropwort, shiitake, agaric mushroom and broccoli did not show such an effect.
In order to determine the effective concentration, 2, 7, and 14 brix black garlic extracts (BGE) were fed to restraint stressed rats and the lipid metabolism was analyzed. The dietary intake of the 14 brix BGE-fed group was $547.64{\pm}13.99$ g/4 weeks and it was significantly higher than that of the control group. The weight of all organs from the all BGE-fed groups showed no significant differences. While BGE concentration increased, BGE-fed groups tend to have low content of blood glucose. It was the lowest in the 14 brix BGE-fed group ($121.32{\pm}3.50$ mg/dl). Total cholesterol content was $54.54{\pm}1.63{\sim}65.84{\pm}2.61$ mg/dl. Total cholesterol content of the 14 brix BGE-fed group was the lowest and, in addition, lower than the normal group. Triglyceride content of serum showed the same tendency. HDL-cholesterol concentrations of the restraint stressed control (RSC) group were significantly higher than those of 7 and 14 brix BGE-fed groups. LDL and VLDL-cholesterol contents showed contrary results. GOT, GTP, and ALP activity of serum were lower when BGE concentration was higher. It is expected that BGE has a liver protective activity. In the liver, total lipids and triglyceride contents were significantly lower in BGE-fed groups than in the ISC group. However, total cholesterol content showed no significant difference between groups. TBARS content in liver of the 2 brix BGE-fed group was not significantly different than control, while 7 and 14 brix BGE-fed groups were lower than control. Glycogen content in the liver was only significantly lower in the 14 brix BGE-fed group than in the RSC group. Findings indicate that feed of BGE over 7 brix contributes to resolving the restraint-stressed rats by improving the lipid metabolism and liver protective activity.

In this study, we assessed antioxidant, anti-diabetic, and anti-Alzheimer activities of Opuntia ficus-indica var. saboten (OFI) at harvest time. OFIs were cultivated December 2015~November 2016 in Jeju island. The 70% ethanol extracts of OFI were used to investigate total polyphenol and flavonoid contents, antioxidant(DPPH and ABTS radical scavenging assay), anti-diabetic(yeast ${\alpha}$-glucosidase and rat ${\alpha}$-glucosidase inhibition assay), and anti-Alzheimer(Acetylcholinesterase and butyrylcholinesterase inhibition assay) activities. Total polyphenol and flavonoid contents of OFIs were $17.40{\sim}23.11{\mu}g$ garlic acid/mg Ex and 2.17~6.22 ug (+)-catechine/mg Ex, respectively. DPPH and ABTS radical scavenging activity of OFIs were 131.98~184.90 mg ascorbic acid(AA) eq/100 g and 63.60~101.83 mg AA eq/100 g, respectively. In the anti-diabetic and anti-Alzheimer activities, 70% ethanol extracts of OFI exhibited moderate inhibition activity, compared to control (acarbose and beberine). Total polyphenol and flavonoid contents, antioxidant, anti-diabetic, and anti-Alzheimer activities were no significant differences by season, respectively. Therefore, information on comparative biological evaluations of OFI may be a beneficial in exploring functional food and drug development.

In Islamic dietary guidelines, Halal foods are allowed as edible blessed food. Most foods were categorized within halal for Muslims. The main point of Halal food is that foods are clean in every process and based on Halal standard which might be different in each country. Most pancreatic ${\beta}$ cells synthetize, store, and release insulin. Specific molecular, functional as well as ultrastructural traits of pancreatic ${\beta}$ cells could control their insulin secretion properties and survival phentoype. Insulin-secreting pancreatic ${\beta}$-cells are essential regulators of mammalian metabolism. In addition, the pancreatic ${\beta}$ cell plays an important role in the pathogenesis of type 1 and type 2 diabetes as improving glucose homeostasis by preserving, expanding and improving the function of this key cell type. However, the pharmacological effect of halal food has not been unclear yet, especially food habit-dependent diabetes. The aim of the this study was to determine the preventive effect of Iran plants extract (Almond, Garlic, Cumin, Ginkgo biloba, Holy basil, Psyllium, Satureja khuzistanica, Fenugreek, Green tea, Ipomoea betatas, Blueberry) on RINm5F cells and MIN6 cells as pancreatic ${\beta}$ cell line. The cytotoxicity of the extracts of Iran plants on RINm5F cells and MIN6 cells were measured by using MTT assays. The preventive effects of Iran plant extracts were measured by WST-8 cell proliferation assay on streptozotocin (STZ)-induced cell death in MIN6 cells. In presented result showed that all extract of Iran plants (0.01-10mg/ml) did not show cytotoxicity in RINm5F cells and MIN6 cells. Among non-cytotoxic extract, the protective effects could be detect in high dose concentration. These results suggest that the extract of Iran plants may serve as a potential therapy for diabetes.
Antifungal activity on major seedborne diasease of crops was screened by the treatment of the extracts from 50 medicinal plants in vitro and in vivo. The extracts of garlic and taxus, Rheum undulatum, Achiranthes japonica, Glycyrrhiza uralensis, Oenothera lamar kiana treated with the blotting filter paper and water agar methods inhibited the growth of Pyricularia oryzae, Alternaria sesamicola, Colletotrichum gloeosporioides, and Alternaria brassicicola among the tested plants. Antifungal activities on infected seeds by soaking methods were shown even at the dilution of the extracts by 10 times. The activity was the highest in soaking seeds at $25^{\circ}C$ for 24 hours. The effect of plant extract on seed germination was not significant as compared with untreated seed. However, early growth of seedling was increased by the treatment of extracts. The extract of taxus slightly inhibited the seed germination of radish and chinese cabbage but those of Achirunthes japonica, Glycyrrhiza uralensis and Oenthfera lamarkiana showed severe damage on the seed germination and early growth of seedling.
Medicinal herbs are significant source of synthetic and herbal drugs. In the commercial market, medicinal herbs are used as raw drugs, extracts or tinctures. Isolated active constituents are used for applied research. For the last few decades, phytochemistry (study of plants) has been making rapid progress and herbal products are becoming popular. According to Ayurveda, the ancient healing system of India, the classical texts of Ayurveda, Charaka Samhita and Sushruta Samhita were written around 1000 B.C. The Ayurvedic Materia Medica includes 600 medicinal plants along with therapeutics. Herbs like turmeric, fenugreek, ginger, garlic and holy basil are integral part of Ayurvedic formulations. The formulations incorporate single herb or more than two herbs (poly-herbal formulations). Medicinal herb contains multitude of chemical compounds like alkaloids, glycosides, saponins, resins, oleoresins, sesquiterpene, lactones and oils (essential and fixed). Today there is growing interest in chemical composition of plant based medicines. Several bioactive constituents have been isolated and studied for pharmacological activity. R. cordifolia is an important medicinal plant commonly used in the traditional and Ayurvedic system of medicine for treatment of different ailments. This review illustrates its major constituents, pharmacological actions substantiating the claims made about this plant in the traditional system of medicine and its clinical applications.
