After the cranberry extract product was included in the "Zhejiang Province Key High-tech Product Development Project Plan" in 2021 , Jianfeng Health Technology Company recently obtained an invention patent for the identification and detection method of cranberry extract.
Cranberry extract is rich in vitamin C , procyanidins, bioflavonoids and condensed tannic acid, which is a special compound with few contents in other fruits and vegetables. It has strong antioxidant, scavenging free radicals, preventing urinary tract infection, inhibiting the adhesion of Helicobacter pylori to the intestines and stomach, and has good effects on improving atherosclerosis, preventing cardiovascular diseases, cancer, senile dementia, etc. Proanthocyanidins are a general term for a large class of polyphenol compounds present in various plants, and their structures are catechin, epicatechin, or polymers of catechin and epicatechin. Studies have shown that A type of proanthocyanidins unique to cranberry is its main antibacterial component, while B type of proanthocyanidins have no similar effect. However, because there is no unified national standard and industry standard for cranberry extract, the standards of relevant production enterprises are different, and the general detection method can not accurately identify the types of proanthocyanidins in the extract, so it is often the behavior of increasing the content of individual components by adding other plant extracts. This new combined identification and detection method developed by
Peak Health identifies whether catechin or procyanidin B2 is added to cranberry extract by thin-layer analysis, and then detects the unique A type procyanidin and its chromatographic distribution in cranberry extract by high performance liquid chromatography, so as to achieve the purpose of improving the accuracy of product determination. The identification method has the characteristics of accurate results and short detection time, which is of great significance to standardize the cranberry extract market and promote the healthy development of the industry, and has been unanimously recognized by peers.
