Flavonoid constituents in the flowers of Pueraria thomsonii Benth.

Study on microwave-assisted extracting of total flavonoids from puerariae radix starch and antioxidation in vitro

Good quality and tasteful puerariae radix starch pudding without sugar could be made from such main ingredients as puerariae radix starch, fresh milk, Aspartame and nutritional food thickening agents by appropriate processing technology.

Microwave-assisted extracting method was used in exacting total flavonoides from puerariae radix starch.

Some defects such as dark gray color and hard-dissolving clots are often found in the instant paste of Kudzu powder currently sold in local area.

After analysis of the resource and present utilization of the root of Kudzu Vine,the further extract process of Kudzu powder and flavone were sutdied,which provided a reasonable and full-use method to the large scale production of Kudzu Vine.
