| titleOfInvention | Method for separating and preparing caryophyllene oxide, beta-farnesene and caryophyllene |
| abstract | The invention discloses a method for separating and preparing high-purity monomer caryophyllene oxide, beta-farnesene and caryophyllene from Flaveria bidentis based on a high-speed countercurrent chromatographic method, which belongs to separation methods of natural product monomers. The method comprises the following steps: using a foreign invasive plant Flaveria bidentis as a raw material, carrying out steam distillation to obtain a volatile oil sample, and separating and purifying with the high-speed countercurrent chromatographic method. A solvent system is composed of n-alkanes, acetonitrile or fatty alcohol, and ethanol or dichloromethane at a volume ratio of 5:(3-4):(1-4), and is suitable for various types of high-speed countercurrent chromatographs; and a great amount of volatile oil crude products can be directly injected in a single experiment for separating to obtain monomer caryophyllene oxide, beta-farnesene and caryophyllene with purity of over 91%, 98% and 97% respectively. The method disclosed by the invention is strong in controllability, simple and convenient to operate, good in separating effect and high in yield, and has a prospect of large-scale preparation. |
