- Abstract: This study was aimed to optimize the extraction process of Aesculi. The extraction process of Aesculi wasoptimized through orthogonal experiment while the transfer rate of escin Ia and escin Ib. And the yield of dry extract. wasadopted as marks. And ratio of solid to liquid, the ethanol concentration, extraction time and extraction temperature werestudies. The results showed that optimized extraction conditions of Aesculi were determined as follows. The ratio of solidto liquid was 1: 10, the ethanol concentration was 70％, extracted for 20 minutes ever stage and the extractiontemperature was 60℃. It was concluded that the extraction process is efficacious for general flavone and icariinextraction. The method is suitable for the standardized production technology of Aesculi.
