Abstract

5-hydroxytryptamine is an indole derivative and can participate in various central nervous activities, so that people generate cheerful mood. The invention discloses a method for preparing natural 5-hydroxy tryptamine hydrochloride by utilizing banana peel. The method comprises the following preparation procedures: cleaning the banana peel, drying and crushing the banana peel; carrying out ultrasonic auxiliary water bath extraction; carrying out column chromatography separation; concentrating an extracting solution; leaching by ethanol; and crystallizing. The method disclosed by the invention is simple and feasible in process, scientific and rational in procedure, rigorous in working procedure, low in cost, easy to implement, small in energy consumption, high in extracting rate and high in product purity. According to the invention, only alcohol and ultrasonic auxiliary water are used for refining, so the pollution of an organic solvent is avoided; a source of natural 5-hydroxy tryptamine hydrochloride is provided, and the method can be widely applied to the field of food processing, so market requirements are met; and a new way is provided for comprehensive utilization of the banana peel, and the method has wide market development prospect.

Description

technical field [0001] The invention relates to a method for preparing natural 5-hydroxytryptamine hydrochloride by using banana peels, in particular to a method for preparing 5-hydroxytryptamine hydrochloride by ultrasonic-assisted water-bath extraction, and belongs to the field of agricultural product processing. Background technique [0002] 5-Hydroxytryptamine is an indole derivative, composed of indole and ethylamine, the molecular formula is C10H12N20, English name: 5-hydroxy tryptamine, referred to as 5-HT, commonly found in animal and plant tissues. 5-hydroxytryptamine was first isolated from serum in 1941, so it is also called serotonin. Subsequently, pure 5-hydroxytryptamine was chemically synthesized in the laboratories of Upjohn and Abbott in the United States, and its health care function was subsequently recognized. At present, it has been confirmed that 5-hydroxytryptamine, as a neurotransmitter, can participate in a variety of central nervous activities, can...
