Embodiment Construction

[0011] Give an implementation former example below, further illustrate invention.

[0012] Put 10 kg of olive powder into a 25-liter extraction kettle after cleaning, drying, and crushing olives into 1mm particle size, and add 95% ethanol and 99.99% liquid CO 2 After mixing in a mixer at a weight ratio of 5:95, the heat exchanger reaches a supercritical state, and then passes into a 25-liter extraction kettle. The pressure in the kettle is 25MPa and the temperature is 50°C. Flow into the 10-liter separation tank, the pressure in the 10-liter separation tank is 9 MPa, the temperature is 55 ° C, the extract from the separation tank is collected into the collector, and then the extract in the collector is injected into the vacuum concentration device to concentrate to 12 kg Left and right, finally enter the spray drier and carry out the spray drying process to obtain 644 grams of finished product, and its total flavonoid content is 42.87%.

Abstract

The invention relates to a method for extracting flavonoids from plants. Against the existed extraction methods, there are organic solvents, like methanol, ethyl acetate, acetone, etc., with the drawbacks of large amount, many varieties, influences on environment, and cumbersome steps, therefore a simple method is presented to extract olive flavonoids. The method includes cleaning olives, drying, crushing, mixing with 95% ethanol and liquid carbon dioxide (>= 99.99%) at a weight ratio of 1:99-15:85, flowing in a heat exchanger and then in a extraction kettle under 8-45 MPa at 30degreeC-90degreeC, flowing into a separation kettle under 7-12 MPa after extraction, entering a vacuum device for condensation after separation, and spray-drying to obtain the finally product.

Description

1. Technical field [0001] The invention relates to a method for extracting flavonoids from plants, in particular to a method for extracting olive flavonoids with a supercritical fluid. 2. Background technology [0002] Flavonoids are a class of important natural organic compounds that widely exist in various parts of plants such as roots, heartwood, bark, leaves, fruits, and flowers. The flavonoids found in plants have vitamin C-like activity and were once regarded as vitamin P. Up to now, flavonoids are still regarded as vitamin P in France and Russia. The anti-oil peroxidation effect of flavonoids was confirmed in the 1960s. Pratt et al. studied the antioxidant properties of flavonoids and believed that flavonoids function as primary antioxidants and have significant antioxidant properties. Since the 1980s, research on flavonoids has gradually turned to their ability to scavenge free radicals, anti-aging and prevention and treatment of senile diseases. [0003] At presen...
