为有效提取茶菜苦苷，采用超声波辅助提取法从茶菜中提取茶菜苦苷。采用高效液相色谱法（HPLC），通过响应面法（RSM）对乙酰水杨酸（Acxisa）进行了研究。研究了提取溶剂、液料比、提取时间、提取温度等实验参数对沙棘KA提取率的影响。测定残留物中KA的纯度。最佳工艺条件为：丙酮体积分数65.5%、温度35 °C、超声时间24.6min、超声频率40 kHz、功率80 W/L、液料比30：1（mL/g）。KA的最大得率为0.708 mg/kg，平均纯度为6.09%，表明超声辅助提取是从R. excisa.
For the efficient extraction of kamebakaurin(KA), the ultrasound-assisted extraction(UAE) of KA from Rabdosia excisa(R. excisa) via response surface methodology(RSM) was investigated with high-performance liquid chromatography(HPLC). Effects of the experimental parameters such as extraction solvent, ratio of liquid to plant material, extraction time and extraction temperature on the extracting efficiency of KA from R. excisa were evaluated, and the purity of KA in residual was calculated. The optimized conditions were 65.5%(volume fraction) acetone, 35 °C, time of 24.6 min with ultrasound of 80 W/L, 40 kHz, ratio of liquid to plant material at 30:1(mL/g). The maximum yield of KA is 0.708 mg/kg, with mean purity of 6.09%, indicating that ultrasound-assisted extraction is a feasible and useful method for extracting KA from R. excisa.
