Problems solved by technology

At present, the prior art discloses the simultaneous determination of six basic anthocyanins in grapes and wine by using high performance liquid chromatography (see "Simultaneous determination of six basic anthocyanins in grapes and wine by HPLC", Liu Bing et al., China Brewing, 2017,36(002):162~165), but only the anthocyanins in grapes and wines containing less anthocyanins were well separated and analyzed, while for blueberries containing more anthocyanins (containing at least 13 Anthocyanins), it is difficult to completely separate the six basic anthocyanins, which will inevitably affect the analysis results

According to the present invention, the simultaneous determination of the six anthocyanins in the blueberry sample is achieved, the standard deviation of the peak area and the retention time is small, the detection limit and the quantification limit of the six anthocyanins are low, and the method has characteristics of high sensitivity, good precision, good reproducibility and good stability.

Description

technical field [0001] The invention relates to the technical field of photoelectrode materials, in particular to a high performance liquid chromatography detection method for anthocyanins in blueberries. Background technique [0002] Anthocyanins or anthocyanins are water-soluble natural pigments, the basic structure of which is 2-phenylbenzopyran, namely the Flavylium, and its structure is shown in the following formula. There are more than 500 kinds of anthocyanins known in nature, of which 6 are the most common, as shown in Table 1, namely cyanidin or hibiscus anthocyanin (Cyanidin), delphinidin or delphinidin , Delphinidin, Peonidin, Petunia or Petunidin, Malvidin and Pelargonidin. Anthocyanins generally exist in the form of glycosides, and often form anthocyanins or anthocyanins (Anthocyanin) through glycosidic bonds with one or more glucose, rhamnose, galactose, arabinose, etc., in which anthocyanin-3-O- Glucoside is the main anthocyanin.
