Abstract

The invention discloses a method for preparing meliternin. The method comprises the steps as follows: taking melicope triphylla as a raw material, carrying out heat reflux extraction, two aqueous phase extraction, column chromatography under polyamide resin, and separating at high-speed counter-current chromatography, so as to obtain meliternin. The method disclosed by the invention is simple in operation, and high in yield and product purity.

Description

technical field [0001] The invention belongs to the technical field of natural plant extraction, and relates to a method for preparing honey rutabaga. Background technique [0002] Meliternin, also known as Meliternin, Sanchumi Zhuyuning, the molecular formula is C 20 h 18 o 8 , molecular weight 386.36, colorless prism, mp.185.5-186°C, insoluble in water, slightly soluble in alcohol and acetone, soluble in chloroform, benzene and dioxane. Mainly distributed in Rutaceae (Rutaceae) plants three out of honey dogwood Melicope ternate bark and honey dogwood Melicope triphylla (Lam.) Merr. Yezhong. Pharmacological studies have shown that Mizhuyuning has a moderate inhibitory effect on collagen-induced platelet aggregation, and its in vitro inhibitory concentration is 100 μg / mL. It also has piscicidal activity, and its minimum lethal concentration MLC is 10 μg / mL. [0003] At present, there are no patents or literature reports on the method of extracting, separating and puri...
