Abstract:
A method for mass-producing an Oplopanax elatus Nakai plantlet is provided to mass-propagate the Oplopanax elatus Nakai effectively from embryogenetic callus derived from an Oplopanax elatus Nakai tissue, thereby preserving endangered Oplopanax elatus Nakai. A method for mass-producing an Oplopanax elatus Nakai plantlet comprises the steps of: (a) explanting a tissue segment of Oplopanax elatus Nakai a cell tissue cultures in an MS culture medium where a plant growth control material including TDZ is added to induce embryogenetic callus; (b) culturing the induced embryogenetic callus in a liquid culture medium or a solid culture medium to induce somatic embryos; (c) culturing the induced somatic embryos in a liquid culture medium or a solid culture medium to propagate them; (d) culturing the propagated somatic embryos in a liquid culture medium or a solid culture medium having a pH of 5.0-5.75 to redifferentiate a plantlet; and (e) acclimatizing the redifferentiated plantlet in a soil where bed soil and sand are mixed in a ratio of 1:1, wherein the culture medium of the step(a) is an MS culture medium where 2,4-D or NAA is further added as the plant growth controlling material. Further, the MS culture medium comprises 10-30 mg/l of sucrose as carbon source.
Abstract:
An extract of Hibiscus cannabinus L.(Malvaceae) and a novel kaempferol compound isolated therefrom are provided to inhibit growth of microorganisms, oxidation and aging in the skin without side effects, so that they are useful in medicines, cosmetics and functional food for improving skin beauty. An extract of Hibiscus cannabinus L. having improved antimicrobial and antioxidizing effects is prepared by extracting Hibiscus cannabinus L. with a solvent selected from water, aliphatic alcohol or alcohol solution, hexane, chloroform and ethylacetate. A novel kaempferol compound represented by the formula(1) is isolated from the extract of Hibiscus cannabinus L. by extracting Hibiscus cannabinus L. with methanol, extracting the crude methanol extract with water, aliphatic alcohol, alcohol solution, hexane, chloroform or ethylacetate to obtain a water layer and an organic layer, and subjecting the water layer and organic layer to silica chromatography, gel filtration chromatography and HPLC(high performance liquid chromatography), sequentially.
Abstract:
Healthy tea with kenaf leaves and a preparation method thereof are provided to facilitate the elution of active ingredients in extraction in hot water by treating the leaves with heat and far infrared ray in a fixed condition, thereby substituting the same for green tea. Healthy tea with kenaf leaves is prepared by the steps of: heating kenaf leaves at 60~100°C for 10~45min; and applying far infrared ray to the leaves at 1.6kw for 10~45min while keeping the temperature at 60~100°C. In the preparation process, large quantities of minerals and antioxidant ingredients are extracted from the kenaf leaves. The extract is especially rich in kaempferols as a polyphenol compound. In addition, the content of physiologically active ingredients in the kenaf leaves is higher than that in green tea leaves.
Abstract:
The present invention relates to a method for producing laver and a use of the same, wherein Pinus Koraiensis oil (phytoncide) produced from a Pinus Koraiensis byproduct is mixed with Canola oil, olive oil, sesame oil, cone oil, bean oil, grape seed oil, sunflower oil, perilla seed oil, avocado oil, almond oil, garlic oil, safflower seed oil, pumpkin seed oil, linseed oil, castor oil, rape seed oil, brown rice oil, coconut oil, peanut oil, cotton seed oil, and cocktail oil in order to be coated on the laver. In particular, the method of the present invention comprises a step of producing mixed oil by mixing edible oil with the Pinus Koraiensis oil (phytoncide) extracted from a pine cone or a pine leaf using water or an organic solvent. The laver coated with the Pinus Koraiensis oil has excellent anti-microorganism activities, and the oil of the laver has an extended acidification period. Accordingly, the shelf life is extended, and the laver of the present invention can be widely used as health food which adds value to a company.
