    Abstract: This invention relates to an extraction method of indole alkaloid from Catharanthus roseus using high pressure and high density carbon dioxide solvent. The method comprises: a) placing Catharanthus in contact with 15-100 deg.C carbon dioxide under 30-500 atm and extracting indole alkaloid; and b) separating indole alkaloid and solvent at 1-10 atm and -30 - 20 deg.C. Using this extration method, there is no residual solvent problem.

    Abstract: PURPOSE: A graphene composite nanofiber and a manufacturing method thereof are provided to secure the excellent mechanical property and electrical property of a graphene. CONSTITUTION: A graphene composite nanofiber contains multiple graphenes concentrated on one side inside a polymer nanofiber or a carbon nano fiber with the diameter of 1~1,000 nanometers. The graphenes are either monolayer graphenes or multilayer graphenes. A manufacturing method of a graphene composite nanofiber comprises the following steps: preparing a spinning solution containing the graphenes; and spinning the spinning solution.
