Abstract: A method for preparing an extract of fermented Gynostemma pentaphyllum with increased contents of saponins or low-molecular-weight saponins, which includes a step of preparing a Gynostemma pentaphyllum fermentation product by fermenting Gynostemma pentaphyllum with a microorganism selected from Aspergillus oryzae, Aspergillus awamori, Aspergillus kawachii, Lactobacillus brevis and Lactobacillus plantarum; and a step of extracting the Gynostemma pentaphyllum fermentation product with hot water.

Abstract: Disclosed herein are a pharmaceutical formulation with high stability and dissolution, and a method for preparing the pharmaceutical formulation. The pharmaceutical formulation comprises a pharmacologically active substance, a solvent, a solubilizer, a surfactant, an antioxidant, and an adsorbent. According to the pharmaceutical formulation and the method, the pharmacologically active substance is mixed with the solvent, the solubilizer agent and the surfactant for improving the solubility of the pharmacologically active substance to obtain an amorphous liquid or semi-solid state, the antioxidant is melted together with the mixture to solve poor chemical stability of the pharmacologically active substance in an amorphous or liquid state, and the adsorbent is strongly adsorbed to the molten mixture so as to be transformed into a powder form so that the resulting molecules are reconstituted into very tiny crystal forms within the adsorbent to ensure chemical stability.
