Objective To study the Baicalin Solid Self-emulsifying Granules preparation process. Methods Investigated by solubility, drawing pseudo-ternary phase diagram, and L9 (33) orthogonal experiment was given, to form a self-emul-sifying effect of self-emulsification time and particle size as indicator to select the best self-emulsifying prescription. Through the screening of the solid adsorbent material, and the determination of cumulative dissolution, the Baicalin sol-id self-emulsifying particles prescription was screened. Results The optimization of the best prescription for oleic acid ethyl ester-Tween 80-PEG400 was 2:7:6. Soluble starch and Baicalin S-SEDDS the mass ratio of 4:1, dissolution was 102.89% in 45 min. Conclusion Baicalin S-SEDDS is easy to prepare and its quality is stable. The dissolution of Baicalin S-SEDDS is improved.
