Abstract

The invention discloses an extraction and purification technology of a hypoglycemic active part. The hypoglycemic active part is prepared according to a following method: adopting teucrium viscidum herb as a raw material, extracting, separating, purifying, and obtaining the hypoglycemic active part consisting of glucoside A of teucrium viscidum, glucoside B of teucrium viscidum and teuevin.

Description

technical field [0001] The invention belongs to the field of biomedicine, and relates to an extraction and purification technology for an effective part for lowering blood sugar, in particular to an extraction and purification technology for an effective part for lowering blood sugar in traditional Chinese medicine Xue Jianchou. Background technique [0002] Traditional Chinese medicine comes from plants, animals, and minerals, and is an important part of medicine. As early as the early Shang Dynasty, people extracted and prepared effective parts from traditional Chinese medicines for disease prevention and treatment, such as oral administration or external application of traditional Chinese medicine decoction; the Ming Dynasty "Compendium of Materia Medica" recorded in detail the process of preparing and purifying camphor by sublimation method; "Bai Yuan Ji" describes the method of extracting and separating crystalline aconitine from fresh Aconitum aconitum; "Introduction t...
