This study reports on the optimization of the conditions of extraction of D-pinitol compound from carob pods by using ultrasonication. For this purpose, the Box-Behnken design, which is a widely used form of Response Surface Methodology, was used to investigate the effects of parameters on the ultrasound-assisted extraction. Four independent variables, temperature (°C), ultrasonic power (W), dilution rate (material:water ratio) and time (min), were studied. The results showed that the highest D-pinitol concentration of 11.98 g/L was obtained with an extraction temperature of 50 °C, ultrasonic power of 207 W, a dilution rate of 1:4 and an extraction time of 120 min. It was found that the D-pinitol concentration of carob extract increased with the effect of ultrasonication during the extraction process. Therefore, ultrasound-assisted extraction could be used as an alternative to conventional hot water extraction with respect to the recovery of D-pinitol from carob pods with the advantages of lower extraction temperatures, shorter extraction time and reduced energy consumption.
本研究报告了使用超声波辅助从角豆荚中提取 D-松醇化合物的条件优化。为此，采用响应面法中广泛使用的 Box-Behnken 设计来研究参数对超声辅助提取的影响。四个独立变量，温度（°C）、超声功率（W）、稀释率（物料：水比）和时间（min）进行了研究。结果表明，在提取温度为 50°C、超声功率为 207W、稀释率为 1:4 和提取时间为 120min 的条件下，可获得最高浓度为 11.98g/L 的 D-松醇。研究发现，在提取过程中，超声作用会使角豆提取物中的 D-松醇浓度增加。因此，与传统热水提取相比，超声辅助提取可以作为从角豆荚中回收 D-松醇的替代方法，具有更低的提取温度、更短的提取时间和更低的能耗。
