  • Effects of Dietary Intake of Agarum cribrosum Ethanol Extract on Lipid Level in Diet-induced Obese Rats
    Korean journal of food and cookery science, 2013
    Co-Authors: Sung-jin Park, Sang-ah Lee, Hyo-nam Song, Tae-gil Park
    Abstract:

    Abstract This research was performed to investigate the effect of Agarum cribrosum ethanol extracts on the levels of lipids in the serum of rats fed a high-fat diet for 10 weeks. Experimental groups were divided into basal diet only (BDG), high fat diet control (HFDCG), high-fat diet and 5% Agarum cribrosum ethanol extract powder (HF5S), and high-fat diet and 10% Agarum cribrosum ethanol extract powder(HF10S) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the control group’s serum total cholcholesterolel of 89.14 mg/dL, the levels of the HF5S and HF10S groups were significantly lowered to 77.26 and 75.47 mg/dL, respectively. Compared with the control group’s LDL-cholesterol leve of 27.41 mg/dL, the LDL-cholesterol levels of the HF5S and HF10S groups were significantly lowered to 20.64 and 20.17 mg/dL, respectively. Also, compared to the control group’s serum triglyceride level of 98.36 mg/dL, the triglyceride levels of the HF5S and HF10S groups were significantly lowered to 87.94 and 87.39 mg/dL, respectively. These results indicate that dietary intake of Agarum cribrosum ethanol extracts might have beneficial effects on obesity by reducing body weight and improving blood lipid profile.Key words : Agarum cribrosum, obesity, HDL-cholesterol, LDL-cholesterol, triglyceride

  • Effects of Agarum cribrosum on the Improvements in Treating Constipation and Plasma lipid Profiles
    Korean journal of food and cookery science, 2013
    Co-Authors: Sung-jin Park, Bom Kim, Min-jeong Kim, Young-eon Kim, Sung-hye Park, Tae-gil Park
    Abstract:

    The present study was conducted to evaluate the effects of Agarum cribrosum on weight change and defecation states in rats with constipation induced by loperamide. Food intake and body weight both decreased in the 5% Agarum cribrosum and loperamide-treated group (SD5) and 10% Agarum cribrosum and loperamide-treated group (SD10), whereas fecal water contents increased by 1.6 and 2.1-fold in the SD5 and SD10 groups, respectively. The concentrations of total-cholesterol, HDL-cholesterol and triglyceride in the sera of the SD5 and SD10 groups were lower than those in the control (C) group. However, the biochemical parameters, GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyruvic transaminase), and glucose levels, were not affected by the level of Agarum cribrosum. In addition, the concentrations of total-cholesterol and triglyceride in the livers of the SD5 and SD10 groups were also lower than those in the control group. The results of the present study demonstrated that Agarum cribrosum might ameliorate constipation symptoms, and lower lipid concentrations in the blood and liver.

  • Nutritional Characteristics and Screening of Biological Activity of Agarum cribrosum
    The Korean Journal of Food And Nutrition, 2012
    Co-Authors: Sung-jin Park, Kyung-jin Min, Tae-gil Park
    Abstract:

    Abstract The purpose of this study is to determine the possibility of using Agarum cribrosum as a natural health food source. To accomplish this purpose, the contents of the general and antioxidant activities of Agarum cribrosum were measured. The contents of carbohydrate, crude protein, crude lipid and ash were 45.4%, 15.0%, 2.3% and 33.1%. The calories of Agarum cribrosum were 262.3 kcal and total dietary 에fiber of Agarum cribrosum was 34.0%. The protein contained a total of 18 different kinds of amino acids. The content of amino acids was 12,402.42 ㎎/100 g. The K was the largest mineral followed by Ca, Na and Mg, implying that Agarum cribrosum is an alkali material. The antioxidant activity of Agarum cribrosum was assessed by various radical scavenging assays using DPPH (2,2-diphenyl-1-picrylhydrazyl), FRAP (ferric ion reducing antioxidant power), reducing power, and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)). All antioxidant activity of Agarum cribrosum extract increased the concentration of the dependents. Total phenolic contents of Agarum cribrosum extract were 34.1±2.56 ㎎/g, and total flavonoids contents were estimated at 4.9±0.26 ㎎/g. General nutrients and other antioxidant bioactive materials in Agarum cribrosum were also potential materials for good health food. It is expected that a follow-up study of Agarum cribrosum through developing processed food and evaluation of their functional properties would provide useful information or sources of functional foods.Key words: Agarum cribrosum, antioxidant activity, total phenol content

  • chemical characterization of essential oil in rhizoma asarum from different sources using gc ms with resolution improved by data processing techniques
    Flavour and Fragrance Journal, 2006
    Co-Authors: Gong Fan, Wang Botang, Chau Footim
    Abstract:

    Rhizoma asarum has been widely used both in phytotherapy and in the food industry because of its pharmacological activities and odoriferous properties. However, besides desirable pharmacological effects, asarum oil is also found to exhibit toxic effects. In this study, gas chromatography–mass spectrometry (GC-MS) with resolution improved by data processing techniques in chemometrics was investigated as a method to chemically characterize essential oils of raw materials of Rhizoma asarum from Liaoning, Gansu and Hunan in China. With the help of chemometric approaches on two-dimensional data from GC-MS, the separation ability of GC was mathematically improved and many more chemical components could be separated and identified since overlapping peak clusters could be resolved into pure chromatograms and related mass spectra for each of the components involved. Qualitative and quantitative determination was conducted with the pure chromatograms and mass spectra obtained by use of similarity searches in the MS databases and the overall volume integration technique, respectively. Moreover, the information on retention times was also used for the identification. The results showed that 96, 94 and 93 chemical components were separated; 69, 67 and 66 of them were tentatively identified, which accounted for about 97.68, 97.51 and 97.63% of the total relative content of the essential oils of Rhizoma asarum from Liaoning, Gansu and Hunan, respectively. In comparison with the determined constituents in essential oils of Rhizoma asarum from three producing sources, most of them matched each other. Copyright © 2006 John Wiley & Sons, Ltd.

  • A comparison of laboratory feeding rates with in situ capture of drift algae by the red urchin Strongylocentrotus franciscanus
    Friday Harbor Laboratories, 2012
    Co-Authors: Roberts Spencer
    Abstract:

    The red sea urchin (Strongylocentrotus franciscanus) is a common subtidal herbivore throughout the northeast Pacific. In the San Juan Archipelago (SJA), Washington, red urchins are subject to little predation pressure and are generally exposed and sedentary. Recent research has shown that detached drift algae are common and abundant at all subtidal depths surveyed (>150 m) in the SJA. Here, we investigated whether red urchin feeding rates observed in the laboratory were consistent with field observations of drift capture. Feeding rates were quantified for captive red urchins; from most to least rapidly consumed (grams per hour), these were: Nereocystis luetkeana, Mazzaella splendens, Saccharina sp., Agarum fimbriatum, and Ulva sp. In the field using SCUBA, we repeatedly collected all algae captured by urchins at one-day and six-day intervals within a 25 m2 permanent transect at a depth of 18 m. We identified, blotted, and massed the ‘stolen’ algae to compare taxonomic composition and mass captured over different time frames, assuming that drift held after a longer time period would more closely reflect urchin preference. Results indicate that at least at this site, availability of particular algae is more important in determining overall drift capture rates than is urchin preference. However, captured Agarum constituted a smaller proportion of total algal mass when urchins were given six days to collect drift, indicating that they are likely discarding this alga. This result is consistent with current and previous lab preference studies and suggests that the large quantity of Agarum drift into deep water is a lowquality subsidy, at least for urchins
