How does the ultrasonic parameters influence the ultrasonic extraction processing?
Time:08/22/2021 Views:1 In many ultrasonic extraction experiments, it was found that the extraction of chemical components in different medicinal materials had different results due to the use of different parameters (such as frequency, sound intensity, etc.). Even for the extraction of the same medicinal material, if the parameters are not selected at the right time, the required components in the medicinal material will not be extracted or good results will not be obtained. As in with ultrasonic extraction yam rhizome potato when soap type, its frequency is different, the proposed rate increases with the increase of frequency, and with high bounce rate (1 MHZ) after ultrasonic extraction of leaching rate and highest when ultrasound was used to extract rutin in the sophora japonica composition, its frequency is different, the rutin yield, the yield decrease with the increase of frequency. And as in the use of ultrasonic extraction of rhubarb root of anthracene wake composition and alkaloid extracted from herba leonuri herba leonuri, found at the same time, the rate of the proposed composition of all decreased with increasing the intensity of ultrasonic, and even greater strength, the forward rate is close to the traditional extraction rate, the influence mechanism remains to be further research. However, it can be seen that the appropriate selection of ultrasonic parameters in the extraction is the key to affect the extraction yield, and the appropriate ultrasonic parameters must be selected for different medicinal materials. The selection range of ultrasonic parameters is one of the evaluation criteria for the quality of ultrasonic equipment. We also hope that under appropriate parameters, ultrasonic equipment can achieve satisfactory results without working noise, and can also be used in large-scale extraction production. The types of equipment used in mass extraction production are described in detail. .
