| Summary: | The invention discloses a preparing method for chlorogenic acid and similar compounds thereof. The preparing method comprises the following steps that firstly, reflux extraction is carried out with an extracting agent; secondly, an extracting solution is concentrated into an extract state; thirdly, extract is dissolved and extracted with ethyl acetate; fourthly, the pH value of a concentrated solution obtained after extraction is regulated to be neutral, and filtration with a macroporous resin column is carried out; fifthly, a thin layer preparing plate is used, a spreading agent is selected for spreading, and high-purity chlorogenic acid and similar compounds thereof are obtained through belt scraping, grinding, column filling, washing and concentration drying. The method is clear in flow, simple and low in cost, and the obtained products through purification are good in color and high in yield and purity; besides, the multiple similar compounds of chlorogenic acid are can be obtained at the same time, and a |
