The present invention provides a kind of donkey-hide gelatin peptide for delaying aging and its preparation method and application, belonging to the field of biotechnology. The preparation method of the donkey-hide gelatin peptide for delaying aging of the present invention comprises: mixing the ultrafine grinding of donkey-hide gelatin with a citric acid aqueous solution, treating it for 60min-90min under a boiling water state, adding a composite enzyme enzymolysis, and drying the obtained filtrate after centrifugation and ultrafiltration to obtain the donkey-hide gelatin peptide. Ultrafine grinding increases the reaction surface area of ​​donkey-hide gelatin; the citric acid aqueous solution can break the peptide bond of the donkey-hide gelatin protein molecule and promote the hydrolysis reaction; the boiling water state puts the reaction system in a vibrating state and shortens the reaction time; the composite enzyme enzymolysis accurately controls the degree of enzymolysis to obtain the donkey-hide gelatin peptide for delaying aging. The experimental results show that the donkey-hide gelatin peptide of the present invention has excellent antioxidant properties, can increase the content of SOD, GSH-Px, and CAT in the plasma of D-galactose-induced aging mice, reduce the content of MDA, and play a role in delaying aging.

This invention discloses a microbial agent for enhancing the disease resistance of tea trees and its preparation method, belonging to the field of agricultural disease control. Through screening of microbial strain combination conditions, the optimal combination conditions were obtained. Experiments verified that the microbial agent prepared by combining *Microbulbarum hainanense* powder (ACCC 60371) and *Streptomyces griseus* var. *rust* (CICC 23624) at a mass ratio of 2:5 achieved control effects of 88.58% and 84.41% against tea leaf blight and leaf spot, respectively. Furthermore, the polyphenol content was significantly higher than that of single-strain control of these two tea tree diseases. This invention provides a source and method for improving disease resistance, as well as the quality and grade of tea.
