Ultrasonic extraction of fenugreek essential oil content of influencing factors

Take 00 g fenugreek powder is placed in a beaker with ether as extractant to extract various setting conditions (solid-liquid ratio, ultrasonic time, soaking time, microwave power). The extract was filtered, dried over anhydrous sodium sulfate and the filtrate was added dehydrated and filtered, and the filtrate evaporated to ether, to obtain the essential oils.

Determination of the minimum inhibitory concentration (M IC) <6 - 7> 3 Results and discussion 31 single-factor experiment 311 the choice of the ultrasonic power ultrasonic cell grinder extraction, due to the power of 100 W, solvent ether serious the splash phenomenon, indicating that power is too large for ether extract fenugreek essential oils in favor of smaller power Ultrasonic cleaner for extraction.

Solid-liquid ratio fenugreek essential oil content in the soaking time 10 m in ultrasonic time 20 m in ultrasonic power 60 W conditions, the study of solid to liquid ratio (1 3,1 4,1 5,1 6,1 7 ) the fenugreek essential oil content. Shows, with the solid-liquid ratio increases the essential oil content increases, the solid-liquid ratio of 14:00, the essential oil content of after with the solid-liquid ratio increases the essential oil content is reduced, soaking time growth will increase the cost, so take the best solid-liquid ratio of 14.

Liquid ratio of fenugreek essential oil content of 313 soaking time of fenugreek essential oil content in the solid-liquid ratio of 14, ultrasonic time 20 min, ultrasonic power 60W conditions, research and soaking time ( 5, 10, 15, 20, 25 m in) the impact of the of fenugreek essential oils content. By known, when the when soaking time reaches 20 m in the essential oil content of up to a maximum, and then with the immersion time, the essential oil content is reduced In addition, the soaking time of growth will increase the amount of volatile ether, so to take optimum soaking time 20 m in.

Soaking time of fenugreek essential oil content 314 ultrasonic time fenugreek essential oil content in the solid-liquid ratio 14, soaking time 20 m in ultrasonic power 60 W to study the ultrasonic time (10, 15, 20, 25, 30 m in) of ultrasonic time of fenugreek essential oil content. By the known essential oil content of up to, ultrasound 20 m in when. When the ultrasonic time of greater than 20 m in the essential oil content is reduced with the increase of the extraction time, In addition, the with ultrasound time increases, the volatile components in the essential oil is volatile, affecting its extraction, so take the top ultrasound The time is 20 m in.

Ultrasonic time of fenugreek essential oil content 315 the ultrasonic power fenugreek essential oil content in the solid-liquid ratio 14, soaking time 20 m in ultrasonic time of 20 min, research ultrasonic power (40, 50 , 60, 70, 80 W) on the impact of of fenugreek essential oils content. By known, with the ultrasonic power increases, the essential oil content increases, the essential oil content of up to a maximum power of 50 W. Further, with the ultrasonic power to further improve some of the low boiling point component of the essential oils with the medium boiling and evaporation losses, decrease the content, so take the best ultrasonic power 50 W.

Conclusion The single factor and orthogonal analysis shows that the ultrasonic extraction of fenugreek essential oil content of the size of the influencing factors were: the ultrasonic power solid-liquid ratio> soak time ultrasonic time, optimize the combination of A 2 B 2 C 2 D 2 , the solid-liquid ratio 14, soak time of 20 m in the ultrasonic time 20 m in, ultrasonic power 50 W, this condition, fenugreek essential oil content of up to 261%.
