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.
