Abstract

The invention discloses a paeonol extracting method which comprises the following steps: grinding moutan bark or cynanchum paniculatum, putting into an extracting kettle, filling the extracting kettle with carbon dioxide pressurizing liquid, and soaking at the temperature of 40-60 DEG C for 1-1.2 hours; adding alcohol into the extracting kettle for extraction, and standing for crystallizing to obtain paeonol. The method is simple, novel, high in recovery rate during extraction, stable in ingredients and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of paeonol extraction, in particular to a paeonol extraction method. Background technique [0002] Paeonol is the main active ingredient in Moutan cortex. It is volatile and can be distilled out with water vapor under a certain vapor pressure. It is a colorless needle-like crystal at room temperature, and its solubility in water is very low. The current experimental research shows that the main pharmacological effects of Cortex Moutan are relatively extensive. With the rise of traditional Chinese medicine and the increasing material and cultural level of the people, the demand for health care products has greatly increased, and the country has attached great importance to traditional Chinese medicine, which has greatly promoted the development and recognition of traditional Chinese medicine technology. At present, the domestic demand for paeonol is 160-200 tons, most of which depend on imports. In terms of ...
