Differences in extraction of ellagic acid from pomegranate peel and gallnut
Ellagic acid is a natural polyphenol component widely existing in various soft fruits, nuts and other plant tissues. It is a dimeric derivative of gallic acid and a polyphenol dialactone. It is found that ellagic acid has obvious inhibitory effect on chemical induced carcinogenesis and other carcinogenesis. It is also one of the effective whitening ingredients recognized by dermatology medicine. Ellagic acid also has a variety of bioactive functions, such as antioxidant function It is also found that ellagic acid also has antihypertensive and sedative effects. Ellagic acid extracted from pomegranate peel is edible. Because gall is an animal gall, it belongs to traditional Chinese medicine, but it is only for external use and is not edible. Because the cost of extracting ellagic acid from gallnut is low, most of the raw materials of ellagic acid health products in the market are extracted from gallnut, pretended to be pomegranate skin and sold to manufacturers as inferior. Now it is urgent to find a landmark material to distinguish whether the source of raw materials is gallnut or pomegranate skin. In this experiment, LC-MS-MS was used to find different components, deduce the structure of unknown compounds, and purchase standards to further verify whether the derivation is correct.
