  • This study made macaroon with the addition of Helianthus tuberosus L. powder so as to increase the application of Helianthus tuberosus L. powder (HTP) to food products and look into the quality characteristics depending on an addition ratio. Helianthus tuberosus L. powder 0%, 0.5%, 1.0%, 1.5%, and 2.0% were added, respectively, to make macaroon. As Helianthus tuberosus L. powder was added more, the moisture content tended to decrease more significantly (p<0.001). As Helianthus tuberosus L. powder was added more, lightness and yellowness tended to reduce more significantly (p<0.001). As Helianthus tuberosus L. powder was added more, the content of total phenol compounds and DPPH radical scavenging activity were significantly increased (p<0.001). In terms of texture analysis, hardness, gumminess, cohesiveness and chewiness were significantly increased, as the Helianthus tuberosus L. powder was increased (p<0.05). In terms of sensory test, regarding taste, 0.5% HTP group had the highest points. And as color, flavor, and texture were improved, 1.5% HTP showed the most desirable result in terms of overall acceptability. Results, if Helianthus tuberosus L. powder is added for cooking macaroon, it seems to increase anti-oxidation function and develop functional macaroon with excellent sensory factors.

  • Helianthus tuberosus is a perennial plant in the genus, Asteraceae. Pork potato has various pharmacological functions such as improving constipation, preventing bowel disease, inhibiting colon cancer, reducing serum cholesterol, lowering blood lipids, and enhancing blood sugar. This study investigated the physicochemical properties of fermented milk by adding Helianthus tuberosus powder. During the fermentation process, the pH of the fermented milk with added Helianthus tuberosus was higher after 16 hours of fermentation. At 48 hours of fermentation, the pH decreased to 3.70, 3.65, 3.63, and 3.59 with 0% (the control group), 1%, 3%, and 5% Helianthus tuberosus added, respectively. In the last 48 hours of fermentation, the acidity increased to 2.35%, 2.57%, and 3.17% with 0% (the control group), 1%, 3%, and 5% Helianthus tuberosus added, respectively. The number of lactic acid bacteria increased as the quantity of Helianthus tuberosus added increased. The highest number of lactic acid bacteria was 9.96 log CFU/g after 16 hours of fermentation with a 5% addition of Helianthus tuberosus . After 48 hours of fermentation, the amount of lactic acid bacteria decreased to 7.84 log CFU/g and 7.88 log CFU/g in the control group and the 1% added Helianthus tuberosus group, respectively. The addition of 3% and 5% Helianthus tuberosus increased the lactic acid bacteria count to 9.48 log CFU/ g and 9.81 log CFU/g, respectively. As the fermentation time increased, oxalic acid and tartaric acid decreased but lactic acid increased. Lactose degraded galactose and glucose over time. After 48 hours of fermentation, the viscosity in the control, 1%, 3%, 5% added Helianthus tuberosus groups increased to 1,006 cP, 1,026 cP, 1,040 cP, and 1,106 cP, respectively. The antioxidant effect was higher in the 5% added Helianthus tuberosus group (84.14%) than in the control group (80.39%) at 48 hours of fermentation. The concentration of polyphenol was 1.6 mg/g and antimicrobial activity was strong against E. coli and Staphylococcus aureus.

  • Helianthus tuberosus has been known to inhibit the growth of weeds and other plants sharing its habitat. This study was conducted to identify the allelochemicals of Helianthus tuberosus which were extracted with water and solvents. Aqueous extracts of leaf, stem, root, tuber and tuber peel of Helianthus tuberosus except tuber did not show significant differences in phytotoxicity to alfalfa seedlings. It was considered that Helianthus tuberosus contained fewer or less potential water-soluble substances that were toxic to alfalfa. Methanol extract of leaves of Helianthus tuberosus was sequentially partitioned in increasing polarity with n-hexane, ethylacetate and n-butanol. Each extract had a yield of 148, 12, 15.7 and 9.5g, respectively. Inhibitory effects on germination of alfalfa seeds treated with four fractions were not significantly different. But the significant reductions on hypocotyl length were observed for all the solvent extracts. Among the four fractions, the ethylacetate fraction showed the most significant inhibition effect on bioassay with alfalfa. Further separation of the active ethylacetate fraction by open column chromatography led to the 25 subfractions. In bioassay of each sub-fraction with alfalfa seeds, sub-fraction No. 13 showed the most inhibitory effect on seedling growth. $^1$H NMR and gas chromatography-mass spectrometry analysis revealed that sub-fraction No. 13 was the mixture of straight-chain saturated fatty acids.

  • BACKGROUND: In order to cultivate upland crops in reclaimed land, economically appropriate crops should be selected. Jerusalem artichoke (Helianthus tuberosus L.) is one of the primary sources for inulin in higher plants. The objective of this study was to evaluate and compare growth and inulin of H. tuberosus L. according to the cultivation region in Korea. METHODS AND RESULTS: 21 varieties of H. tuberosus L. were collected in Korea, and then 7 varieties of H. tuberosus L. were selected for this study. To compare growth and inulin, those varieties were cultivated in reclaimed land and upland soils. The growth of H. tuberosus L. significantly decreased when cultivated in reclaimed land. There was an increas at 17.8% in the content of white H. tuberosus L. tuber inulin in reclaimed land. CONCLUSION: The content of inulin in H. tuberosus L. tubers was found to be dependent on cultivation region and tuber color. There was a difference of the inulin content between the tubers with different colors in reclaimed land. Purple tubers of P20 were considered suitable varieties for cultivation in reclaimed land. White tubers of W1 and W8 were also considered suitable varieties for cultivation in reclaimed land.

  • Methanol extract of Helianthus tuberosus L. (Compositae) flower was investigated to research the anti-oxidative activity by using a Caenorhabditis elegans model system. Ethyl acetate soluble fraction of the methanol extract showed the most potent DPPH radical scavenging activity. The ethyl acetate fraction was measured on its activities of superoxide dismutase (SOD), catalase, and oxidative stress tolerance with reactive oxygen species (ROS) level in C. elegans. Furthermore, in order to verify if regulation of stress-response gene is responsible for the increased stress tolerance of C. elegans which treated by the ethyl acetate fraction, we checked SOD-3 expression using a transgenic strain. Consequently, the ethyl acetate fraction of H. tuberosus flower increased the catalase and SOD activities in a dose-dependent manner in C. elegans, reduced ROS accumulation dose-dependently. Besides, the ethyl acetate fraction-treated CF1553 worms showed higher SOD-3::GFP intensity than the control group.

  • Helianthus tuberosus is perennial plant as Compositae family and is shown various physiological activities such as analgesic, antipyretic, anti-inflammatory, anti-fungal, anti-spasmodic, aperient, cholagogue, diuretic, spermatogenic, stomachic, and tonic effects. In this study, we investigated the antidiabetic and anti-inflammatory effects of pancake mixture powder (PM) supplemented with H. tuberosus (PMH) in rat skeletal muscle L6 cells and murine macrophage RAW 264.7 cells, respectively. PM and PMH inhibited in vitro α-glucosidase activity. Glucose consumption was increased by PM and PMH without cytotoxicity in rat myoblast L6 cells. Western blot analysis revealed that PM and PMH down-regulated glycogen synthase kinase (GSK)-3β activation in L6 cells. PM and PMH inhibited inflammatory mediator, nitric oxide (NO) production without cytotoxicity in LPS-induced RAW 264.7 cells. The anti-diabetic and anti-inflammatory effects of PMH was more stronger than those of PM. Anti-diabetic and anti-inflammatory effects of PMH would be due to functional characteristics of the supplemented H. tuberosus and the presence of garlic and onion used as ingredients of PM. Taken together, our results that addition of functional materials such as H. tuberosus in product has synergic effects and PMH is potential candidate for treatment of diabetes through inhibiting inflammation.
