Abstract: A method for preparing ginseng extract rich in rare ginsenosides is disclosed. Ginseng roots or ginseng stems and leaves are extracted, enzymatically hydrolyzed and treated with high temperature and high pressure. The preparation method can quickly and effectively increase the proportion of rare ginsenosides in the ginseng extract. After in vitro antioxidant experiments and in vivo experiments with Hidradenitis elegans nematode, the extract and related complexes were proved to be effective in antioxidant, anti-oxidative stress, and improving age-related muscle decline and other dysfunctions. After genetic and metabolomic studies, the anti-aging mechanism was proved to be related to the expression of genes associated with nutrient sensing, stress-related pathways and redox processes, and showed innate immune response and redox process GO enrichment, proving its oxidative stress resistance.

Abstract: The present invention belongs to the field of drug preparation and detection, and particularly discloses a preparation method for a Eucommia ulmoides Oliv. leaf extract. The extract is obtained from Eucommia ulmoides Oliv. leaves (the mixture of the Eucommia ulmoides Oliv. leaves and Eucommia ulmoides Oliv. male flower) by enzymolysis and extraction of ethanol and water, and can effectively solve the problem that the extract is not easy to spray dry (the Eucommia ulmoides Oliv. leaves contain colloidal substances). The pharmacodynamic experiment proves that the Eucommia ulmoides Oliv. leaf extract has good effect of protecting the health of the renal function. The present invention also develops a detection method for the extract, which not only realizes the quality control of the extract, but also has the advantages of good repeatability and stability.
