Abstract

The invention discloses a synthetic method of a deep eutectic solvent and a method for extracting and purifying eleutheroside B by using the deep eutectic solvent. The synthetic method comprises the following steps: mixing choline chloride, L-proline and water; stirring the mixed components at a constant temperature to synthesize a deep-eutectic solvent, drying the acanthopanax, grinding the acanthopanax into powder, and sieving the powder with a 60-80-mesh sieve; and putting acanthopanax powder into an extraction tank, adding a deep-eutectic solvent, and then stirring at constant temperature to obtain an extracting solution of eleutheroside B; The method for extracting the eleutheroside B in the acanthopanax by using the eutectic solvent and adopting a constant-temperature heating and stirring method is efficient, green, safe and low in cost, and compared with a 70% ethanol solvent, the method has relatively high extraction efficiency and relatively simple and convenient purification process on the eleutheroside B in the acanthopanax.

Description

technical field

[0001] The invention belongs to the technical field of medicine, and more specifically relates to a method for synthesizing a deep eutectic solvent and a method for extracting and purifying eleutheroside B using it. Background technique

[0002] Acanthopanax senticosus (Rupr.rtMaxim.) Harms] is the dry root and rhizome of Acanthopanax, mainly distributed in Northeast China, and also found in Russia, South Korea, North Korea, Japan and other countries. "Chinese Materia Medica" records that Acanthopanax has the effects of nourishing the liver and kidney; strengthening bones and muscles; diuresis and nourishing the kidney. Modern pharmacological studies have shown that eleutheroside B has excitatory effects on the central nervous system, and its effect is different from that of amphetamine compounds. Eleutheroside B is not only low in toxicity, but also does not disturb normal sleep. Eleutheroside has anti-fatigue effects , stronger than ginseng extract and gin...
