Key antioxidant compounds in Ampelopsis grossedentata extract targeting ROS
Dihydromyricetin (DHM)
Dihydromyricetin, also known as ampelopsin, is the primary bioactive compound found in Ampelopsis grossedentata extract. Because it is such a strong antioxidant, this flavonoid is a great way to fight reactive oxygen species. Studies have shown that DHM is a good way to get rid of different kinds of free radicals, such as hydrogen peroxide, superoxide anions, and hydroxyl radicals. DHM has a special chemical structure that lets it give electrons to unstable free radicals. This neutralizes them and stops reactive damage to cell parts. DHM also increases the activity of antioxidant enzymes found naturally in the body, like superoxide dismutase and catalase. This makes the body's defense against oxidative stress even stronger. Ampelopsis grossedentata extract has strong antioxidant action from DHM, which is a big part of why it protects cells from damage caused by ROS.
Myricetin and Quercetin
In addition to dihydromyricetin, Ampelopsis grossedentata extract contains other important flavonoids such as myricetin and quercetin. Along with DHM, these chemicals work together to make a full antioxidant defense system. Myricetin, which has a structure that is similar to DHM, has been shown to be very good at getting rid of free radicals and stopping lipid peroxidation. Another flavonoid that has been studied a lot is quercetin. It is a powerful antioxidant and anti-inflammatory. It can directly stop ROS from doing damage and also raise the production of antioxidant genes, which makes the body's defenses stronger. Because Ampelopsis grossedentata extract has these extra flavonoids, it has broad-spectrum antioxidant action, which means it can fight a lot of different oxidative stresses.
Phenolic Acids and Other Polyphenols
Ampelopsis grossedentata extract is an antioxidant because it contains a lot of phenolic acids and other polyphenolic substances. A few of these are gallic acid, caffeic acid, and chlorogenic acid... These phenolic chemicals have been shown to be strong antioxidants that can get rid of different types of free radicals and stop chemical reactions. Ampelopsis grossedentata extract contains a variety of polyphenols that aid in the fight against oxidative stress. Some of these chemicals can attach to metal ions and stop them from joining with other chemicals to create ROS. There are people who can stop free radical chain reactions. This stops the damage from oxidation from spreading. It is even better at protecting cells from damage caused by oxygen radicals when all of these antioxidants in Ampelopsis grossedentata extract work together.
Mechanisms of free radical scavenging and oxidative stress reduction
Direct Neutralization of Free Radicals
Free radicals are directly neutralized by Ampelopsis grossedentata extract, which is one of the main ways it fights oxidative stress. There are antioxidants in the product, like dihydromyricetin and other flavonoids, that give away electrons. They are happy to give unstable free radicals their electrons, which neutralizes them and stops them from damaging cellular parts through oxidative damage. This direct scavenging action is very important for lowering the body's total reactive oxygen species load. As per studies, Ampelopsis grossedentata extract can successfully get rid of many types of free radicals, such as superoxide anions, hydroxyl radicals, and peroxynitrite. This broad-spectrum activity makes the extract very good at fighting oxidative stress from many different sources. This makes it possible for it to help avoid diseases related to oxidative damage.
Enhancement of Endogenous Antioxidant Systems
Another significant mechanism through which Ampelopsis grossedentata extract reduces oxidative stress is by enhancing the body's endogenous antioxidant systems. The bioactive compounds in the extract, particularly dihydromyricetin, have been shown to upregulate the expression and activity of key antioxidant enzymes. Some of these are catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx). Superoxide radicals are broken down by SOD into hydrogen peroxide. CAT and GPx then break this down even further into water and oxygen. Ampelopsis grossedentata extract improves the body's natural ability to get rid of reactive oxygen species by making these enzymes work better. This indirect antioxidant effect works with the direct free radical scavenging action to reduce oxidative stress in a more complete way. Some studies also show that the substance may raise amounts of glutathione, an important antioxidant for cells, which would make the body's defense against oxidative damage even stronger.
Inhibition of Pro-oxidant Enzymes
Ampelopsis grossedentata extract also demonstrates the ability to inhibit pro-oxidant enzymes, which are enzymes that contribute to the generation of reactive oxygen species. Oxygenase is one of these enzymes, and it helps make superoxide radicals. A lot of study has shown that flavonoids, like dihydromyricetin, and other things in Ampelopsis grossedentata extract can stop xanthine oxidase from doing its job. Less superoxide radical is made because of this blocking, which lowers oxidative stress in general. The extract also stops an enzyme called NADPH oxidase from doing its job. This enzyme helps make ROS, especially in tissues that have veins. These pro-oxidant enzymes are blocked by Ampelopsis grossedentata extract. This helps get rid of free radicals that are already present and stops new ones from forming. This gives us more than one way to lower reactive stress. This process is very important when making too many ROS is a main cause, like in heart diseases and inflammatory illnesses.
Comparative antioxidant potency versus other polyphenol-rich extracts
ORAC and DPPH Assays
When comparing the antioxidant potency of Ampelopsis grossedentata extract to other polyphenol-rich extracts, standardized assays such as Oxygen Radical Absorbance Capacity (ORAC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) are commonly used. These assays provide a quantitative measure of an extract's ability to neutralize specific types of free radicals.
