Procyanidolic oligomers, also known as procyanidins or condensed tannins, are a subclass of flavonoids and are commonly found in a variety of fruits, vegetables, and beverages, including red wine and green tea.One of the main constituents of procyanidolic oligomers is protocatechuic acid, which is known for its antioxidant properties.
Due to its antioxidant properties, protocatechuic acid is commonly used as a raw material in the pharmaceutical industry to produce dietary supplements and other health products. Antioxidants help protect the body against oxidative stress, which can lead to the development of various diseases such as cancer, cardiovascular disease, and neurodegenerative disorders.
In addition to its antioxidant properties, protocatechuic acid has also been shown to have anti-inflammatory and antimicrobial effects.These properties have led to its use in various topical ointments and skin care products to help promote wound healing and protect against skin infections.
In summary, the use of protocatechuic acid as a pharmaceutical raw material is due to its antioxidant, anti-inflammatory, and antimicrobial properties, which make it a useful ingredient in the production of dietary supplements, skin care products, and other health-related products.
