The invention provides a green extraction process and
system for active ingredients of Kushui roses. According to the process,
ethanol gradient extraction is adopted, in the first stage, 70%-80%
ethanol is used for extracting fat-soluble volatile oil components, and in the second stage, 50%-60%
ethanol is combined with low-temperature ultrasonic extraction for extracting water-soluble
polyphenol and flavone; meanwhile, a temperature sensor, a concentration sensor and a
turbidity sensor are integrated, the rotating speeds of a cooling pump, a liquid supplementing valve and a centrifugal
machine are dynamically adjusted through a PLC, closed-
loop control of zero loss of volatile oil components is achieved through a condensation
backflow and
nitrogen protection unit, and therefore it is guaranteed that extraction is more efficient, and the purity of obtained products is higher; the content of corresponding active ingredients in each batch of products is relatively stable, and the method can be applied to efficient production of bioactive ingredients in the fields of
skin care
cosmetics, medicines, health care products and the like.
