Abstract:
PURPOSE: Zein nanofiber which contains sorghum extract is provided to show high antibiosis and be used in the field of medical treatment and beauty treatment due to no cytotoxicity. CONSTITUTION: A manufacturing method of Zein nanofiber that has wrinkled nanofiber surface containing sorghum extract to improve heat-resisting and antibiotic comprises the manufacturing step of spinning solution and a step of electric radiation. The step of manufacturing spinning solution manufactures the blend solution by dissolving Zein which is a native protein extracted from corns, sorghum, and the sorghum byproduct extract in the solution. The electric radiation step electrically radiates the spinning solution. The extract of the sorghum or the sorghum byproduct is characterized as being the golden Sorghum bicolor L. Moench extract. The sorghum byproduct extract is characterized as being the golden sorghum stem extract and the golden sorghum leaf extract. The component of the sorghum extract and the sorghum byproduct extract is chemical formula 1 or chemical formula 2. Mask sheet which has non-uniform nanofiber surface for improving heat resistance and antibiotic comprises Zein nanofiber which contains sorghum extract manufactured by the electric radiation on the top portion of the nonwoven fabric of the mask sheet.
Abstract:
PURPOSE: A composition containing a natural pigment extract of sorghum or polyphenol compounds such as apigenin, apigeninidine, luteolin, and luteolinidine is provided to suppress neuraminidase activity, and to be used as a pharmaceutical product, a food additive, or a feed additive with antibacterial or antiviral activity. CONSTITUTION: A pharmaceutical composition as an antibacterial agent or an antiviral agent contains a natural pigment extract of sorghum and suppresses neuraminidase. The pharmaceutical composition contains one or more kinds of polyphenol compounds selected among apigenin of chemical formula 1, apigeninidine of chemical formula 2, luteolin of chemical formula 3, and luteolinidine of chemical formula 4. A food additive with antibacterial or antiviral activity contains the one or more kinds of polyphenol compounds as active ingredients. A method for preparing the extract comprises the step of extracting sorghum powder with a methanol solvent containing 0.1-1% of hydrochloric acid at 5-40 deg. C.
Abstract:
PURPOSE: A polyphenol compound and young barley leaf extract with an effect of suppressing neuraminidase is provided to release generated virus into the outside of cells and to strongly suppress neuraminidase. CONSTITUTION: A pharmaceutical composition for preventing or treating influenza virus contains young barley leaf extract as an active ingredient and suppresses neuraminidase. The pharmaceutical composition contains a compound selected from compounds of chemical formulas 1-7. The extract is prepared using alcohol of 1-4 carbon atoms. The young barley is prepared by harvesting buds 5-15 days after sprouting and freeze-drying. A pharmaceutical composition for preventing or treating influenza virus contains the compound.
