Objective: This research aims to improve the taste of andrographitis compound particle

and to research the preparation technology of taste masking suspension particle which suits children. Method: Particle coating was applied to prepare taste masking particle

through building the relation of concentration with mouth taste and dissolution of dehydroandrographolide of two inspection methods to evaluate the effect of taste masking. On the basis of taste masking

the suspension of taste masking particle was prepared that can be taken by children suitably. Result: Eudragit E100 coating is good for tasting masking. The suspension particles made with the method of coating dispersed in water evenly and tasted good. Conclusion: The coating particle has good effect on taste masking. And the preparation of taste masking suspension particle is suitable for children patients to take.
