| 摘 要： | 采用响应曲面法建立Box-Behnken模型，优化桂枝中桂皮醛的超声提取工艺。以桂皮醛的得率为指标，通过单因素法考察料液比、提取温度、提取时间和超声功率对桂皮醛提取效果的影响。在此基础上，采用4因素3水平响应曲面法分析，确定桂枝中桂皮醛的最优提取工艺。结果表明:响应面法优化桂皮醛超声提取工艺的最适条件为提取温度58.69 °C、料液比1∶11.6、提取时间52.35 min、超声功率98.49 W、得出的模型预测值为 20.27 mg·g?1。在最佳提取条件下，桂皮醛的得率为20.04 mg·g?1，与预测值相近，二者相对偏差为0.09%。运用响应面法得到了提取桂皮醛的最优条件，表明此方法具有可行性和实用性。

| Abstract: | A Box-Behnken model was established by using the response surface methodology to optimize the ultrasonic extraction of cinnamaldehyde from dried twigs of cassia cinnamon (Cinnamonum cassia). The yield of cinnamaldehyde was used as the index to analyze the effects of solid-liquid ratio, extraction temperature, extraction time duration and ultrasonic wave power on the extraction efficiency of cinnamaldehyde from the dried cassia cinnamon twigs by using the single factor method. On the basis of the results, the extraction of cinnamaldehyde from the dried cassia cinnamon twigs was optimized by using the response surface methodology with four factors and three levels. The optimum conditions for the ultrasonic extraction of cinnamaldehyde were as follows: extraction temperature 58.69 °C, solid-liquid ratio 1∶11.6, extraction time duration 52.35 min, ultrasonic wave power 98.49 W, and the predicted model value 20.27 mg·g?1. Under the optimal extraction conditions, the yield of cinnamaldehyde was 20.04 mg·g?1, similar to the predicted value, with their relative deviation being 0.09%. The optimum conditions for extracting of cinnamaldehyde from the dried cassia cinnamon twigs were determined based on the response surface methodology, indicating this extraction method is feasible and practical. |
