Flavonoids
Flavonoids are a diverse class of phytochemicals that are widely distributed in plant-based foods. They are characterized by their chemical structure, which consists of a core chromone structure with two benzene rings (A and B rings) connected by a three-carbon bridge (C ring).
The variations within the flavonoid group arise from differences in the presence or absence of hydroxyl groups (OH) and the extent of alkylation and/or glycosylation. Hydroxyl groups can be attached to different positions on the benzene rings, resulting in different subclasses of flavonoids.
The major subclasses of flavonoids include flavonols, flavanones, flavanols, flavones, anthocyanins, and isoflavones. Flavonols, such as quercetin and kaempferol, are characterized by the presence of hydroxyl groups at the 3-position and/or 5-position of the flavonoid structure. Flavanones, like naringenin and hesperetin, lack hydroxyl groups on the B ring but may have them on the A ring.
Flavanols, such as catechins and epicatechins, possess hydroxyl groups on both the A and B rings. Flavones, like apigenin and luteolin, have hydroxyl groups at the 4-position of the B ring. Anthocyanins, responsible for the vibrant colors of many fruits and flowers, are glycosylated forms of flavonoids. Isoflavones, found predominantly in legumes, have a distinct structure with a benzopyran ring.
Understanding the variations within each group of flavonoids is important as their chemical structures influence their biological activities and potential health benefits.
Stilbenes
Stilbenes are a subclass of polyphenols that play a significant role in human health. They are known for their potential health benefits and can be found in a variety of dietary sources. One notable health benefit of stilbenes is their anti-HIV-1 activity.
Research has shown that stilbenes exhibit antiviral properties, particularly in inhibiting the replication of the HIV-1 virus. They have been found to interfere with the proteolytic processing during viral multiplication, which is crucial for the virus to replicate effectively.
