考察白及提取物白及胶最佳提取工艺，制备白及胶乳膏剂。方法 采用水提醇沉

Investigate the best extraction process of white and gum white and gum to prepare white and gum cream. Methods The water and alcohol precipitation method was used to extract the white and gum, and the orthogonal design method was used to select the best extraction scheme. Based on the single-factor inspection, the appearance and stability were used as indicators, and the multi-factor optimization matrix formulation was used. 1. Under high temperature and cold storage conditions, investigate the influence of each component of the matrix formulation on the cream molding, determine the composition of the matrix formulation of the cream; and perform quality inspection on the optimal and best cream containing medicine.

Examine the best extraction process of white and extract white and glue, and prepare white and latex cream. Methods The method of water-tiol sink extraction of white and glue, combined with orthogonal design method to select the best extraction scheme, the use of single-factor examination on the basis of appearance characteristics and stability as an indicator, the use of multi-factor optimization of matrix prescription, in centration, high temperature, refrigeration conditions to examine the effect of each component on the molding of the cream, determine the composition of the matrix of the cream, and the best quality inspection of the best cream.

To investigate the best extraction technology of Baihe extract and Baihe gum, and prepare Baihe latex plaster. method Water extraction and alcohol precipitation method was used to extract Baihe gum, and orthogonal design method was used to optimize the best extraction scheme; on the basis of single factor investigation, taking appearance and stability as the index, multi factor optimization was used to optimize the matrix prescription, and under the conditions of centrifugation, high temperature and cold storage, the influence of each component in the matrix prescription on the formation of the cream was investigated to determine the matrix prescription composition of the cream; and optimization was made The quality of the cream was examined.<br>
