Abstract: This article is aimed to study the optimal process of preparation of Golden water-soluble gel, and to establish its quality control method. Taking the gel forming properties, stability, water loss rate, pH as investigation index, the best extraction process was screened by single factor and orthogonal test design. TLC method was used to identify the product of trichosanthin, rhubarb, and the content of paeoniflorin was determined by HPLC method. The optimal condition of preparation process is to use 1% carbomer as gel matrix, 10% glycerol as humectants, and 0.5%triethanolamine as pH modulators; trichosanthes and rhubarb could be detected by TLC method, with pH range 5.00 - 5.15. The linear range of paeoniflorin was 29.04-945.20μg·mL-1, the average recovery was 98.80%, and RSD was 2.91% (n=9). Golden gel forming process is simple and quality controllable with reliability and good stability.
