Objective: To determine the best extraction process of aescin flower tincture. Methods: Taking the total saponin yield of re-building as evaluation index, single-factor and orthogonal experimental design was used to determine the best extraction technology of A. tinctorius tincture. Results: The best extraction process was as follows: The effective components in the medicinal herbs Pieces were extracted with 100 times amount of 75% ethanol by dipping method, and the extract of Aescin was extracted according to the preferred process. The yield of total saponins was 1.3%. Conclusion: The optimized process is reasonable, economical and feasible.
