2021 , Jianfeng Health Technology Company recently obtained an invention patent for cranberry extract identification and detection method. Cranberry extract is rich in vitamin
C, procyanidins, bioflavonoids and condensed tannic acid, which is a special compound with little content 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 a good effect on improving atherosclerosis, preventing cardiovascular disease, 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. The study showed that the unique A type of proanthocyanidins in 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
B2is 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.
