Abstract

The invention discloses a method for obtaining effective components in ants through supercritical carbon dioxide extraction. The method comprises the steps of (1) selecting ant bodies; (2) putting theant bodies into a drying device, and adjusting temperature in the drying device to change relative to time according to a sine curve rule; (3) putting the ant bodies into a carbon dioxide extractor,and sequentially carrying out cell fragmentation for two times; (4) dividing a whole extraction process into four stages, sequentially increasing a carbon dioxide flow from the first stage to the laststage, wherein a first transition section is arranged between the first stage and the second stage, and a carbon dioxide flow in the first transition section, a second transition section and a thirdtransition section is linearly increased; (5) after extraction, feeding an extraction fluid into a separator for separating. According to the method provided by the invention, the yield of the effective components is improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for extracting active ingredients in ants with supercritical carbon dioxide. Background technique [0002] Ants are rich in organic substances and have good medicinal value. Studies have shown that ant powder has pharmacological effects on anti-inflammatory, analgesic, bactericidal, anti-cancer and anti-cancer, and improving immunity. However, the traditional ant processing methods are mainly crushing, grinding and organic solvent extraction. Crushing and grinding methods cannot effectively remove impurities such as silt, leaves or grass clippings on ants, and there are problems such as excessive heavy metals, and some biologically active substances are also easily lost during processing. Although the organic solvent extraction method can extract the active ingredients in the ants, there is a problem of solvent residue, which affects product quality, pollutes the environment...
