Problems solved by technology

[0006] At present, domestic and foreign studies on the biotransformation of saponins have found that the transformation pathway of a single strain is limited, and saponin resources cannot be fully utilized. Therefore, many scholars have begun to use mixed enzyme systems and mixed strains for biotransformation research, and the effect is ideal. Transformation from traditional single strain

Abstract

The invention belongs to a preparation method of deapio-platycodin D. The preparation method for preparing the deapio-platycodin D is characterized in that the deapio-platycodin D is prepared by two or more bacterial strains, including a pichia kudriavzevii bacterial strain and a bacillus velezensis bacterial strain. According to the preparation method, two bacterial strains of different transformation mechanisms are used for the first time, and platycodin is transformed in a mixed fermentation manner, so that the yield of the deapio-platycodin D is effectively increased. Biotransformation ofthe platycodin is performed through the fermentation characteristics of the bacterial strains, so that safe and environment-friendly production of the platycodin can be realized, platycodon resourcescan also be sufficiently used, and the platycodin being low in bioactivity contained in the platycodon resources is transformed into saponin being high in bioactivity, and the effect of turning wasteinto wealth is achieved.

Description

technical field [0001] The present invention relates to a preparation method and application of de-apitoside platycodon saponin D, and relates to a preparation method of de-apitoside platycodon saponin D by adopting a mixed strain containing Pichia kudriazwii strain and Bacillus velesii. its application. Background technique [0002] Platycosides have the functions of treating hyperlipidemia, hypertension, diabetes, obesity, etc., and the main biologically active components are triterpene saponins (platycosides). According to the survey, more than 30 kinds of Platycodin saponins and various saponins have been isolated and identified. Platycodin D (Platycodin D), referred to as PD, is a white crystalline powder with a density of 1.56g / cm 3 , with a melting point of 228-237°C and a molecular formula of C 57 h 92 o 28 , relative molecular weight is 1224.58, good water solubility. Platycodon saponin D is a kind of platycodon acid disaccharide chain saponin, and its sugar gr...
