Abstract

A process for extracting the active polyphenol substances from the natural plants includes such steps as washing, drying, pulverizing, loading it along with the deoxidizing purified water in an extractor, heating at 50-90 deg.C under the protection of inertial gas while stirring for 30-60 min in order to extract the active components or ultrasonic or microwave extracting for 10-40 min 1-5 times, collecting liquid extract, filtering, cooling concentrating and drying.

Description

1. Technical field [0001] The invention relates to an active extraction method of plant polyphenols, and belongs to the field of extraction and processing of natural products. 2. Background technology [0002] Tea leaves, grape seeds and natural herbal medicines Kezi, Catechu, Rhubarb, Moutan Bark, Agrimony, Guanzhong, Geranium, White Spoon, etc. are rich in plant polyphenols. Modern scientific research shows that plant polyphenols are not only a natural non-toxic antioxidant, but also an ideal natural medicine, which has biological activities such as scavenging free radicals and anti-oxidation, and has antibacterial, anti-virus, anti-cancer and anti-inflammatory effects. It has good effects in cancer, tumor suppression, and cardiovascular disease prevention and treatment. [0003] The production and sales of plant polyphenols have a history of more than ten years at home and abroad. At present, plant polyphenols are mainly used in the following aspects: anti-tumor drugs; c...
