A novel hexahydropyrroloindole
alkaloid extracted from wolfberry fruit can effectively solve the problems of extracting and preparing novel hexahydropyrroloindole
alkaloid A from wolfberry fruit and realizing its application in preparing drugs for preventing and treating type 2 diabetes. The dried wolfberry fruit is heated under
reflux for extraction, concentrated, and applied to a macroporous adsorption resin column. The product is eluted with water,
ethanol, and
acetone in sequence. The
ethanol fraction is concentrated under reduced pressure, extracted, mixed with
silica gel, gradient eluted, the same fractions are combined, the target component is eluted, mixed with
silica gel, gradient eluted, the fractions within the
retention time are collected, concentrated, and dried. The application of the prepared novel hexahydropyrroloindole
alkaloid A in preparing drugs for preventing and treating type 2 diabetes can significantly promote glucose consumption in
insulin-resistant HepG2 cells, improve
glucose uptake capacity, promote
glycogen synthesis, and enhance the activities of key glycolytic enzymes
hexokinase and
pyruvate kinase. The development and application prospects are broad and the economic and
social benefits are significant.
