| titleOfInvention | Method for preparing high-purity chlorogenic acid from bamboo leaf extract |
| abstract | A method for preparing high-purity chlorogenic acid from bamboo leaf extract belongs to the technical field of natural product extraction. The method comprises the following process steps: 1) separating by macroporous resin: loading bamboo leaf extract as raw material onto macroporous adsorbent resin, sequentially eluting with distilled water, 60% ethanol and 95% ethanol, collecting unadsorbed part and water eluted part respectively, and concentrating to obtain concentrate A and concentrate B; 2) high-speed countercurrent chromatographic separation: separating and purifying the concentrate A and the concentrate B in an HSCCC chromatograph by taking an ethyl acetate-methanol or acetonitrile-acetic acid-water two-phase solvent system to obtain a chlorogenic acid monomer. The method can simply, conveniently and efficiently obtain the chlorogenic acid compound from the bamboo leaf extract, realizes effective separation of the chlorogenic acid compound from the bamboo leaf flavone component of the bamboo leaf extract, is suitable for small-scale or industrial application in the production and preparation processes of the chlorogenic acid compound and the bamboo leaf flavone component, and is beneficial to improving the additional value of production. |
