1. Microwave extraction: Microwave has an obvious synergistic effect on the extraction of flavonoids in the leaves of orientalis, reducing the amount of extractant, shortening the extraction time, and improving the yield. It has the advantages of saving time, high efficiency, and energy saving, thereby reducing the extraction cost. It is superior to the traditional direct heating extraction method in many aspects.
The most suitable process conditions are: φ (ethanol) 60%, solid-liquid mass ratio 1:20, microwave time 4min, microwave power 385W.
The verification test was carried out under this process condition, and the yield of the extract of oriental cypress leaves was as high as 5.905%. Microwave extraction can greatly shorten the extraction time, reduce the amount of extractant, and increase the yield of extract.
 

2. Type of extracting solution: In the process of extracting flavonoids in leaves of cypress leaves with methanol, ethanol, or ethyl acetate, the extraction time and temperature are the main factors affecting the extraction effect.
Using methanol as the extraction solution, the optimal extraction scheme is extraction time 6h, extraction temperature 70oC, the ratio of liquid to material 8:1, and the yield of total flavonoids is 8.450%.
Using absolute ethanol as the extraction solution, the optimal extraction scheme is: extraction time 6h, extraction temperature 85 degrees Celsius, the ratio of liquid to material 10:1, and the yield of total flavonoids is 7.422%.
