Abstract
The invention relates to a preparation method of flavone-enriched pueraria lobata starch. The preparation method is characterized by comprising the following steps: cleaning, slicing, pulping, filtering, settling, concentration, drying and packaging. The preparation method has the beneficial effects that an ethanol solution is used as an extracting agent, and the total flavone content of the starch is 2.3 to 2.8 percent, namely every 100 grams of starch contain 2.3 to 2.8 grams of flavones; and the total flavone content is nearly 100 times higher than that of the conventional radix puerariae starch. Compared with a conventional radix puerariae starch extraction process, the process is simple.
Description
Technical field
The present invention relates to a kind of be rich in flavone Radix Puerariae starch preparation method.
Background technology
Herba Gelsemii Elegantis (Pueraria lobata (Willd.) Ohwi) are leguminous plants, belong to medicine food dual purpose plant, China's distribution
It is relatively wide, containing abundant Radix Puerariae starch in Radix Puerariae, contain a kind of material for being called isoflavone in Radix Puerariae, metabolism can be improved
Some indexs of syndrome, including blood pressure, hypercholesterolemia ester and blood glucose.The special isoflavone of puerarin, exists only in Herba Gelsemii Elegantis
In, it may be possible to most beneficial material.Research shows that puerarin contributes to reducing 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 drop by the method for reasonable layout glucose
Hypoglycemia, such as drop it off it is useful where (muscle), and reduce its distribution in adipose cell and blood vessel.
To clean, stripping and slicing is beaten current people, and water immersion is filtered, sedimentation, and remove impurity is concentrated, and prepared by the technique such as dry, system
In standby Herba Gelsemii Elegantis starch, the content of Radix Puerariae total flavoness is less than 15-50 milligrams per in 100 grams of starch.(0.015-0.020) %, this
Plant processing technique and cause substantial amounts of Radix Puerariae flavone loss, reduce the function nutrition of Radix Puerariae starch.
