  • We recently reported that a water extract of laurel or turmeric, 1,8-cineole enriched fractions, showed hypolipidemic activity in the zebrafish model. Therefore, the present study investigated the cineole's anti-oxidant and anti-inflammatory activities in lipoprotein metabolism in vitro and in vivo. Cineole had inhibitory effects on cupric ion-mediated oxidation of lipoproteins in general, while simultaneously enhancing ferric ion removal ability in high-density lipoprotein (HDL). Hypercholesterolemia was induced in zebrafish using cholesterol-feeding treatment, 4% cholesterol, for 3 weeks. After feeding with or without the addition of cineole, the results revealed that cineole possessed lipid-lowering and anti-inflammatory activities in hypercholesterolemic zebrafish. In addition, serum amyloid A and interleukin-6 levels were lowered and lipid accumulation was decreased in the liver. Conclusively, 1,8-cineole was found to have anti-oxidant activities in lipoprotein metabolism both in vitro and in vivo with simultaneous reduction of lipid accumulation in the liver of zebrafish.

  • This study examined radiation detection characteristics of spices (cumin, caper and turmeric), other small fruits (hut-gae berry and boxthorn), and pollen extract product. Each samples were irradiated at dose of 1, 5, and 10 kGy and analyzed by the thermoluminescence (TL) and electron spin resonance (ESR) methods. To compare between non-irradiated and irradiated food, all samples were irradiated with $^{60}Co$ gamma-ray source. In TL analysis, most of samples could be applied to detect irradiated foods because of showing TL ratio above 0.1. The glow curves examined by TL method were estimated in the range of $150{\sim}250^{\circ}C$ in irradiated samples. In ESR measurements, the intensity of ESR signal (single-line) increased as the increase of irradiation dose. In particular, the specific ESR signals of irradiation-induced radical were detected in hut-gae berry and pollen extract product. As a results, it is considered that TL and ESR methods can be used to detect both hut-gae berry and pollen extract product. But cumin, caper, turmeric and boxthorn irradiated with gamma ray could be detected only by TL method. It is concluded that TL and ESR methods are suitable for detection of irradiated samples and a combined method is recommendable for enhancing the reliability of detection results.

  • In this study, free radical scavenging activities (ABTS, DPPH, NBT, TBARS, and ORAC) and anti-obesity potential were evaluated using 50% ethanol extract from fermented Curcuma longa L. (FCE50). FCE50 showed free radical scavenging activities and anti-oxidant potential. Lipid accumulation and intracellular TG content were significantly reduced by 25.8% and 28.6%, respectively, by $250{\mu}g/mL$ of FCE50 compared to adipocytes. Glucose uptake was significantly reduced by 12.0%. FCE50 significantly reduced mRNA expression of acetyl-CoA carboxylase in 3T3-L1 cells. These results indicate that the anti-adipogenic effect of FCE50 might be due to its radical scavenging activity and anti-oxidant potential.

  • Methanol extract of the rhizomes of turmeric, Curcuma longa L., effectively controlled the development of red pepper anthracnose caused by Colletotrichum coccodes. In addition three antifungal substances were identified from the methanol extract of C. longa rhizomes as curcumin, demethoxycurcumin, and bisdemethoxycurcumin using mass and $^{1}H-NMR$ spectral analyses. The curcuminoids in a range $0.4-100\;{\mu}g/ml$ effectively inhibited the mycelial growth of three red pepper anthracnose pathogens, C. coccodes, C. gloeosporioides, and C. acutatum. The three curcuminoids inhibited mycelial growth of C. coccodes and C. gloeosporioides to an extent similar to the synthetic fungicide dithianon did, but the synthetic agent was a little more effective against C. acutatum. The curcuminoids also effectively inhibited spore germination of C. coccodes, and bisdemethoxycurcumin was the most active. Among the three curcuminoids, only demethoxycurcumin was effective in a greenhouse test in suppressing red pepper anthracnose caused by C. coccodes.

  • Purpose: Periodontal disease is a chronic condition caused by microbial infection and mediated by the host's immune response. Phytotherapy is a therapeutic approach that utilizes a renewable resource capable of supplying less expensive medicines for the world's growing population. This review aimed to present clinical evidence on the use of complementary medicinal herbs in the treatment of periodontal diseases. Methods: Different databases were searched using the terms "herbal" and "periodontitis." All included studies were examined with a focus on herbal indications, type, and prescription length. Dentists' therapeutic and prophylactic herbal prescribing habits were also assessed. Results: Various herbs such as turmeric, neem, aloe-vera, pomegranate, catechu, tulsi, cloves, lemon grass, green tea, tea tree oil, peppermint, garlic, pineapple, oak bark, babul, bakul, sage, coriander, moringa, amla, guava, and grape seed extract have been used in the treatment of periodontitis. These herbs have been reported to exhibit a range of therapeutic effects, including anti-inflammatory, antiplaque, antihalitosis, antiresorptive, antioxidant, antibacterial, antifungal, antiviral, and antimicrobial properties. These components can be utilized in various forms such as mouth rinse, gel, oil, toothpaste, aqueous extract, mouthwash, or tooth powder. Conclusions: Several readily available herbal formulations are now available on the market and have been shown to be effective as supplemental periodontal phytotherapy. However, these should be used under the supervision of a dental professional to ensure optimal benefits and effectiveness. Therefore, it is necessary to improve the understanding of suggested herbal prescription practices among dental professionals.

  • This study was performed to investigate the effect of water extracts from Namhae special crops (NSC) on improved serum lipid composition using rats fed a 1% cholesterol diet for 4 weeks. Male Wister rats (200-210 g) were divided into six groups: Normal cholesterol diet group (Normal), 1% cholesterol diet group (Control), 1% cholesterol and NSC water extract powder supplemented groups, including, turmeric (Tu-EP), cactus (Ba-EP), aloe vera (Al-EP) and asparagus (As-EP). No significant differences were observed for food intake or body weight gain between the control and experimental groups. However, food efficiency ratio (FER) was the lowest in the As-EP group. The serum levels of total cholesterol and triglycerides in the NSC water powder extract supplement groups were lower than those in the control group. The serum high density lipoprotein (HDL)-cholesterol content in the Tu-EP group was higher than that in the other experimental groups. Very low density lipoprotein (VLDL)-cholesterol content in the As-EP group was similar to that in normal group. Furthermore, the VLDL content in the Al-EP group was lower than that in the normal group. Serum antioxidant activity by TBARS level and DPPH radical scavenging were significantly higher in the Ba-EP group than that in the control group. Hepatic total cholesterol and lipid content in the Al-EP group decreased significantly compared to that in the control group. These results suggest that the NSC water extract may reduce serum cholesterol and prevent oxidative stress by stimulating antioxidative systems in rats fed a 1% cholesterol diet.

  • Three curcuminoids [curcumin (CUR), demethoxycurcumin(DEM), bisdemethoxycurcu in (BIS)] are major yellow pigments in turmleric (Curcuma longa L.) root. Contents of curcuminoids in turmeric roots collected from 6 locations were analyzed using, high performance liquid chromatography (HPLC) equipped with reversed-phase column, an UV-Vis detector at 420nm, and eluted with a mixture of acetonitrile: $0.1\%$ acetic acid in water (50 : 50, v/v) as mobile phase. The stability of curcuminoid pigments in $80\%$ methanol extract solution were investigated during storage in a freezer at $-20^{\circ}C$, room temperature in the dark, and light condition. Calibration curves for the determination of curcuminoids were made with significant linearity $(r^2=0.999**)$. Average content of total curcuminoids was 171.5 mg/g, with 91.6 mg/g of CUR, 56.9 mg/g of DEM, and 23.0 mg/g of BIS. Amount of curcuminoids during storage in a freezer was almost not changed while those in room temperature wert reduced and rapid degradation appeared after 60 days. Within 90 days, about $50\%$ curcuminoid decreased in the dark and about $70\%$ in the light condition, indicating the decomposition of curcuminoid pigments followed under light and heat.

  • This study was performed to investigate the antioxidative effects of solvent extracts of eighteen curry spices. Yields of the curry spices extracted by methanol, ethylacetate and hexane were $6.4{\sim}42.9%$, $3.9{\sim}26.2%$ and $1.6{\sim}29.2%$, respectively. Methanol, ethylacetate and hexane extracts of spices were added up to 1,500 ppm in the rice bran oil and antioxidative effects of extracts were tested by Rancimat. Induction periods of spices extracted by methanol were in the order of rosemary(33.5hr)>sage(29.1hr)>ginger(28.6hr)>turmeric(26.9hr)>nutmeg(25.8hr)>oregano(25.6hr)>thyme(25.3hr)>BHT(24.5hr)>control(22.6hr). Those of ethylacetate extracts were as follows: rosemary(43.9hr)>sage(30.9hr)>oregano(29.0hr)>thyme(27.5hr)>ginger(27.1hr)>BHT(24.5hr)>control(22.6hr). Those of hexane extracts were in the order of rosemary(47.4hr)>sage(31.4hr)>oregano(27.3hr)>ginger(25.5hr)>thyme(25.1hr)>control(22.6hr). Solvent extracts of rosemary, sage, oregano, ginger and thyme showed significant antioxidative effects. Two thousands ppm hexane-extract of rosemary was the most effective. Addition of hexane-extracts of rosemary didn't show any synergism with the hexane extracts of sage, oregano, ginger, and thyme.

  • The antimicrobial activity of Curcuma aromatica Salab. was investigated. The Curcuma aromatica Salab. extract showed antimicrobial activity against six pathogens tested. These were Listeria monocytogenes ATCC 19115, Pseudomonas fluorescens ATCC 21541,Staphylococcus aureus ATCC 29273, Salmonella typhimurium ATCC 21541, vibrio parahaemolyticus ATCC 17802, and Aeromonas hydrophila KCTC 2358. Antimicrobial activity was alsonoted when the extract was tested against four isolates of Bacillus sp. purified from spoiled tofu. The growth of various pathogens was significantly inhibited (100 10,000-fold) upon growth in tryptic soy broth containing 0.05 0.2%(w/v) Curcuma aromatica Salab. extract(CE), after incubation for 12hr at $37^{\circ}C$. The growth of the four Bacillus isolates was also significantly inhibited in nutrient broth containing 0.05 0.2% CE after incubation for 24hr at $37^{\circ}C$. Although the antimicrobial activity of CE was decreased by heat treatment at temperatures above $80^{\circ}C$, the activity remained relatively high after heat treatment at $121^{\circ}C$ for 15min. The minimum inhibitory concentrations of CE were 0.1 0.3%(v/v culture) for the six pathogens, and 0.2 0.25% for the Bacillus isolates, respectively.

  • In the present study, we investigated the effect of ethyl acetate fraction from 50% ethanol extract of fermented Curcuma longa L. (FCEE) on lipid metabolism in 3T3-L1 cells. The safety range of FCEE was up to $300{\mu}g/mL$. Effects of FCEE on lipid accumulation and intracellular triglyceride (TG) content in 3T3-L1 cells were examined by Oil Red O staining and AdipoRed assay. Compared to adipocytes, lipid accumulation and intracellular TG content were significantly reduced by 10.2% and 13.7%, respectively, upon FCEE treatment at a concentration of $200{\mu}g/mL$. Glucose uptake by 3T3-L1 cells was significantly reduced by 36.6% compared to adipocytes at a concentration of $200{\mu}g/mL$. On day 8, free glycerol release into the culture medium was significantly reduced compared to adipocytes at concentrations of 50, 100, and $200{\mu}g/mL$ of FCEE. FCEE significantly stimulated RNA expression of AMP-activated protein kinase (AMPK) and suppressed mRNA expressions of sterol regulatory element-binding protein-1c (SREBP-1c), CCAAT/enhancer binding proteins ${\alpha}$ ($C/EBP{\alpha}$), and peroxisome proliferator- activated receptor ${\gamma}$ ($PPAR{\gamma}$) in 3T3-L1 cells. These results suggest that FCEE inhibits adipogenesis through activation of AMPK mRNA expressions and inhibition of SREBP-1c, $C/EBP{\alpha}$, and $PPAR{\gamma}$ mRNA expressions.
