Embodiment Construction
[0030] The present invention will be further described below in conjunction with specific embodiments.
[0031] 1. Ultrasonic-microwave extraction process of total flavonoids from leaves of medusa, the extraction process comprising the following steps:
[0032] (1) get the cilantro leaf after drying in the shade and pulverize, obtain the powder of 80 meshes, take by weighing 5g of citrifolia leaf powder, for subsequent use;
[0033] (2) place 5g of the leaf powder of wolfberry that was weighed in step (1) into a 250ml conical flask, add the corresponding material-to-liquid ratio, the ethanol of the corresponding concentration, at the corresponding temperature, place it in an ultrasonic cleaning machine for ultrasonic 20min, extract 2 times;
[0034] (3) transfer all the solutions mixed with thorn bone powder obtained in step (2) into three-necked round-bottomed flasks, place them in a microcomputer microwave chemical reactor, and react for corresponding time;
[0035] (4) ta...
