Catechin

Procyanidin B1 is a polyphenolic compound, which is a type of naturally occurring organic compound. It is primarily sourced from various plants, including grape seeds, apples, and cocoa. This compound is a proanthocyanidin, specifically a type of flavonoid, and is often found in the skins, seeds, and leaves of these plants.

(-)-Epicatechin is a flavonoid compound, which is a type of polyphenol that can be found in various natural sources such as cacao beans, green tea, and certain fruits. Structurally, it belongs to the class of catechins and is known for its antioxidant properties.

(+)-Gallocatechin gallate is a polyphenolic compound, which is a specific type of catechin predominantly derived from green tea leaves, Camellia sinensis. It belongs to the flavonoid class of phytochemicals, known for their diverse biological activities. The compound exhibits potent antioxidant properties by scavenging free radicals and chelating metal ions, thereby reducing oxidative stress. It also modulates various signaling pathways involved in inflammation and cell proliferation.

Procyanidin B3 is a flavonoid compound, which is a type of plant-derived polyphenol, sourced primarily from the seeds and skins of various fruits, especially grapes and apples. It functions primarily through strong antioxidant activity, neutralizing free radicals and reducing oxidative stress. This mode of action is fundamental to its potential therapeutic effects, as oxidative stress is a contributor to numerous chronic diseases.

(-)-Catechin is a flavonoid compound, classified as a polyphenolic antioxidant, which is predominantly derived from plant sources such as tea leaves, cocoa, and various fruits. Its molecular structure allows it to scavenge free radicals and chelate metal ions, exhibiting potent antioxidant properties. This reactive nature contributes to its ability to modulate signaling pathways and inhibit enzymatic activities related to oxidative stress and inflammation.

Procyanidin A2 is a type of flavonoid, which is a class of bioactive compounds extracted primarily from various plant sources such as grape seeds, cranberries, and cocoa. These compounds are known for their complex molecular structures that include oligomeric catechins. Procyanidin A2 exerts its effects by modulating oxidative stress pathways through its potent antioxidant activity. It neutralizes free radicals, thus protecting cellular components from damage and potentially ameliorating oxidative stress-related conditions.
