Abstract

The invention discloses a method for separating and purifying bergamot lactone from clausena dentata. The method comprises the following steps: S1, preparation of an extract crude product: adding dried branches and leaves of clausena dentata into an ethanol aqueous solution for extraction, filtering, concentrating under reduced pressure to obtain extract, adding water into the extract for suspension, extracting with petroleum ether, and recovering the solvent to obtain an extract crude product, and S2, performing HSCCC separation on the crude extract: taking cyclohexane/ethyl acetate/n-butyl alcohol/methanol/water in a volume ratio of 6: 4: 1: 5: 5 as a solvent system, taking an upper phase as a stationary phase, taking a lower phase as a mobile phase, taking a host rotating speed as 850 r/min and a mobile phase flowing speed as 2 mL/min, after two phases are balanced, feeding a sample, starting to record a chromatogram at the same time, collecting 140min-165min eluent, and performingvacuum concentration until the eluent is dry. The method is simple in step, and the raw material advantages of the clausena lansium are fully utilized.

Description

technical field [0001] The invention belongs to the field of chemistry, and in particular relates to a method for separating and purifying bergamot lactone from the yellow bark of serrata. Background technique [0002] Bergamot lactone is a kind of coumarin compound, which widely exists in natural plants and has various pharmacological activities such as anticancer and analgesic. The chemical structure of bergamotide is as follows. [0003] [0004] Hu Lifeng et al. provided a method for the separation and purification of bergamot lactone in notopterygium by silica gel column chromatography-high-speed countercurrent chromatography (Separation and purification of bergamot lactone in notopterygium by silica gel column chromatography-high-speed countercurrent chromatography, Chinese Herbal Medicine, Volume 44, Issue 6 March 2013), but this method still needs to rely on the silica gel column chromatography that is loaded down with trivial details not easy to use in mass prod...
