Abstract

The invention provides a method for promoting content of resveratrol in grape leaves, grape stems and grape fruits, which comprises preparation and dilution of colloid aluminum inductive agent and dry powder, and the relative use method thereof in the induction of the grape materials. The method of the invention has the characteristics of high efficiency, stability, low residue and low toxicity in promotion of the resveratrol in induced grape fruit and the relative by-products (such as leaves and stems) in the grape production. The method of the invention does not need precise instrument or automatic equipment, can be applied in a large scale in town and township enterprises with rich grape resources, not only can increase the grape quality, but also can improve the comprehensive utilization of the grape planting wastes, and can lead the grape trees to generate a certain resistance to pathogenic bacteria, thus decreasing the loss caused by plant diseases.

Description

technical field [0001] The invention relates to a method for increasing the content of resveratrol in grape leaves, grape stems and grape fruits. Background technique [0002] Resveratrol (resveratrol: trans-3,5,4'-trihydroxystilbene) is a stilbene compound. In 1992, Siemann and Creasy first confirmed that wine contains natural trans-resveratrol, and it has important medicinal effects on human liver, skin, heart, blood circulation and lipid metabolism. In recent years, resveratrol has been found to have special effects in anti-inflammation, cardiovascular protection, estrogen regulation and anti-tumor, and its medicinal value has attracted widespread attention. [0003] Resveratrol exists in some medicinal and edible plants, such as cassia, hellebore, knotweed, grapes, and peanuts. In terms of obtaining resveratrol, the selection of suitable plant materials has become a hot issue in this field. The current source of commercially available resveratrol is mainly extracted f...
