[Objectives]To establish the quality standard for Wuteng Qufeng Zhitong Powder.[Methods]The orthogonal design was used to optimize the water extraction process with the amount of water,extraction time and extraction times as the factors,and the content of protocatechuic acid and dry extract rate as the indicators.The content of protocatechuic acid of Embelia parviflora Wall in Wuteng Qufeng Zhitong Powder was determined by HPLC.[Results]The best water extraction process is:soaking for 0.5 h,adding water to decoct twice,adding 12 times of water for the first time,adding 10 times of water for the second time,decocting for 1 h each time.The average content of protocatechuic acid was 14.41 mg/g,and the average dry yield was 23.47%.[Conclusions]The preparation of Wuteng Qufeng Zhitong Powder by water extraction method has the characteristics of high efficiency and suitable for large-scale production.The quality control method is reliable,rapid and accurate,and can effectively control the quality of the lotion. |
