Description
Technical field
The present invention relates to one kind to be rich in flavones Radix Puerariae starch preparation method.
Background technique
Elegant jessamine (Pueraria lobata (Willd.) Ohwi) is leguminous plant, belongs to medical and edible dual purpose plant, China's distribution
Relatively wide, pueraria starch rich in Radix Puerariae contains a kind of substance for being called isoflavones in Radix Puerariae, can improve metabolism
Some indexs of syndrome, including blood pressure, high cholesterol ester and blood glucose.The special isoflavones of Puerarin, exists only in elegant jessamine
In, it may be possible to most beneficial substance.Studies have shown that Puerarin helps to reduce blood pressure and cholesterolemia.But it have been found that
Maximum effect is to adjust blood glucose.Diabetes and obesity can all cause blood Puerarin that can drop by the method for reasonable layout glucose
Hypoglycemia such as drops it off useful place (muscle), and reduces it in the distribution of fat cell and blood vessel.
People are at present to clean, stripping and slicing, and mashing, water impregnates, and filter, and settle, and clean, concentration, the techniques preparation such as dry, system
The content of Pueraria Flavonid is no more than in 15-50 milligrams of every 100 grams of starch in standby elegant jessamine starch.(0.015-0.020) %, this
Kind processing technology causes a large amount of kudzu root flavone and is lost, and reduces the function nutrition of Radix Puerariae starch.
Summary of the invention
