超声波提取芫荽(香菜)茎叶挥发油及其对NaNO_2的清除作用的研究

Ultrasonic Extraction of Coriander(cilantro)Leaf Essential Oil and its NaNO_2 Scavenging Activity

通过超声波法提取香菜茎叶挥发油,研究超声波提取功率、时间、温度对香菜精油提取率的影响,实验结果是提取最佳工艺组合为:提取温度25℃,提取功率60 W,提取时间100 min,香菜精油得率为0.285%。将提取的香菜茎叶挥发油用于对在模拟胃液条件下亚硝酸盐消除率的研究。实验结果表明,香菜茎叶挥发油能有效清除模拟胃液条件下的亚硝酸盐,清除率为72.72%。

This artical focuses on extracting coriander leaf volatile oil through the ultrasonic method to research the influences of the extraction efficiency of coriander oil under the different ultrasound extracting power, time, and temperature. The experimental result is the best extraction process combination which are 25℃extracting temperature, 60 W extracting power, and 100 min extracting time. The yield of coriander oil is 0.285%. Also, researches the extracting coriander oil's Nitrite eliminating rate under the simulated gastric juice condition. The result showed that coriander leaf volatile oil can efficiently eliminating Nitrite under the simulated gastric juice condition, and the eliminating rate is 72.72%.
