Abstract

The invention discloses active extracts of rosa roxburghii tratt fruit, and a preparation method, a detection method and application thereof. The preparation method comprises the following steps of: extracting rosa roxburghii tratt fruit by conventional processes; filtering to remove rosa roxburghii tratt residues; concentrating the filtered solution at the reduced pressure; extracting with an organic solvent; recovering the organic solvent; adding water for dispersing; filtering; washing with water for depositing; mixing the filtered solutions; and respectively drying the filtered solution and the deposit to respectively obtain an active extract B and an active extract A. The preparation method provided by the invention solves the problems of extraction, enrichment and refinement of effective active components in the rosa roxburghii tratt, and industrial production is easy to realize by the preparation process; the detection method provided by the invention can effectively ensure the quality of the active extracts; and the obtained active extracts have obvious anti-malignant tumor activity, have synergistic action with clinical anti-cancer drugs, have better alpha-glucosidase inhibition activity, can be used for preparing drugs and adjuvant drugs for treating malignant tumors or used as health food additives, can also be used for preparing drugs and health products for preventing or treating diabetes or used as food additives, and have higher application values and good application prospects.

Description

technical field [0001] The present invention relates to the active extract of Rosa roxburghii, especially the active extract of triterpenoid active parts of Rosa roxburghii and the active extract of triterpenes and flavonoid (+)-catechin effective parts of Rosa roxburghii and its preparation method, detection method and The application belongs to the technical field of traditional Chinese medicine or natural medicine. Background technique [0002] Malignant tumor (cancer) is a disease that seriously endangers human health. According to statistics, in 2007, there were about 12 million new cancer patients in the world, 7.6 million people died of cancer, and about 20,000 people died of cancer every day. In addition, the incidence of cancer continues to rise, and it is estimated that there will be 15 million new cancer patients worldwide in 2020. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colon cancer, breast cancer, cervical cancer and nasopharyngeal cancer...
