Study on the anti-inflammatory and antioxidant properties of plant extracts
Leave a message
For thousands of years, plants have been an important source of traditional medicines for treating many diseases. Nowadays, scientific research pays more and more attention to the therapeutic potential of natural plant compounds. In particular, plant extracts show great prospects in fighting inflammation and oxidative stress, two potential processes related to many chronic diseases.
Plant extracts are taken from different parts of plants, and they are like the saviors of our health, helping to solve problems such as diabetes, heart disease, brain diseases and even cancer. They don't stop there-they also try to keep their intestines happy and healthy.
Immunoregulation and inflammation control:
Eating plants helps the body become stronger and reduces problems caused by allergens and weak immune system or persistent inflammation. Plant extracts provide protection against inflammatory process by down-regulating pro-inflammatory cytokine cyclooxygenase (COX) and inhibiting nuclear factor kappa B (NF-kB) translocation to the nucleus.
The bioactive components of plant extracts are also very important for controlling oxidative stress, reestablishing the balance of reactive oxygen species (ROS) production and enhancing the antioxidant potential of cellular enzymes.
Anti-inflammatory ability of plants:
Inflammation is the body's protective response to injury, infection or disease. Although acute inflammation plays a vital role, chronic inflammation may become a problem and lead to arthritis, asthma, cancer, heart disease and other diseases. At present, anti-inflammatory drugs can relieve symptoms, but may have adverse side effects, especially for long-term use.
Researchers are now actively exploring safer, plant-derived alternatives to traditional anti-inflammatory drugs for anti-inflammatory diets. Some key plant compounds with anti-inflammatory properties include:
1. Flavonoids are pigments that provide bright colors for plants. They exist in fruits, vegetables, grains, herbs, spices, tea and so on. Flavonoids have antioxidant properties and can protect cells from damage. They can also block enzymes that produce chemicals that cause inflammation. Specific flavonoids such as quercetin, luteolin and kaempferol are very effective in reducing inflammation.
2. Alkaloids contain nitrogen and exist in some plant families. Some well-known alkaloids, such as morphine, are used as powerful painkillers. Studies have shown that other types of alkaloids also have the potential to alleviate inflammation.
3. Saponins are natural detergents found in many plants. They can interact with cell membranes and block inflammatory pathways. Glycyrrhizin and other saponins in licorice root have similar anti-inflammatory effects as cortisone.
4. Tannin is a polyphenol compound, which can be divided into two categories: hydrolyzed tannin and condensed tannin. They act as antioxidants and can inhibit inflammatory chemicals such as cytokines. Tannin exists in many plant foods and gives some fruits astringency.
5. Terpenes are active compounds in plant essential oils such as eucalyptus, mint, clove, rosemary and thyme. These natural hydrocarbons can relieve swelling, fever and pain. α and β resinoids are triterpenoids with strong anti-inflammatory properties.
These phytochemicals limit the production of inflammatory mediators such as prostaglandin according to different enzymes and pathways. By taking advantage of the medicinal value of plants, researchers hope to develop anti-inflammatory therapy with fewer side effects, more effective and more sustainable than existing drugs.
Plant antioxidants for anti-oxidative stress;
When reactive oxygen species (ROS) are out of balance with human antioxidant defense, it may lead to cell damage, that is, oxidative stress. Because active oxygen is related to many diseases, scientists are exploring plant-derived antioxidants as a therapeutic solution.
After the discovery of vitamin C, the research on plant antioxidants was accelerated. However, narrowing the gap between laboratory antioxidant testing and real-world efficacy remains a challenge. Plants produce antioxidants such as vitamins, enzymes and polyphenols to promote their growth, development and resist environmental pressure. Their complex secondary metabolites, especially phenolic antioxidant compounds, have shown antioxidant effects in both laboratory and human research.
Not just inflammation: Other uses of plant extracts:
These plant extracts are not only good for inflammation. They can also help improve fertility, fight bacteria that cause diseases, and reduce the side effects of certain drugs. For example, extracts from pine bark and grape residues are very resistant to bacteria (grapes) and are useful in oral care. Just as plants have many talents to keep us healthy.
Stay young with antioxidants:
Polyphenols are a superhero compound and have another effect: they can help slow down aging. A study on rosemary flowers shows that they have anti-aging effect, which gives us another reason to appreciate these natural wonders. It's like nature's way of keeping us young.
Protect our brains and nerves:
Polyphenols found in plants are also good for our brains and nerves. They help blood flow to our brains and even prevent diseases that affect our nerves. Curcumin, turmeric from root, is used in Asian medicine because of its anti-inflammatory and antibacterial properties, which may be beneficial to neurological problems. Just as plants support us in brain and nerve health.
Anti-inflammatory and antioxidant properties of herbal extracts;
1. Cranberry extract: Cranberries are rich in antioxidants and polyphenols such as anthocyanins. Health benefits include urinary tract health, cardiovascular support, cancer prevention and fighting various diseases. It is emphasized that the protein omics of cranberries, the interaction of polyphenols and the formulation of functional foods and supplements need to be further studied.
2. Fenugreek extract: It has antioxidant and anti-inflammatory effects and is beneficial to health. It can fight against harmful substances, reduce swelling and enhance the body's defense ability.
3. Ginkgo biloba extract: It is an ancient plant and has many health benefits because of its rich bioactive components. It has many medicinal properties, such as anti-cancer, anti-oxidation and anti-inflammation, which makes it of great value in the treatment of nervous, cardiovascular and respiratory diseases. However, the potential side effects and interactions with drugs need further study to ensure safe medical use.
4. Neem extract: Neem has antibacterial properties, and azadirachtin in seeds can inhibit microbial growth. The ethanol extract of Azadirachta indica has antibacterial activity against Staphylococcus aureus and MRSA. It is an effective antioxidant, and azadirachtin and azadirachtin have anti-free radical scavenging activity. In addition, Azadirachta indica helps cancer treatment by regulating cell signal pathway, and plays an anti-inflammatory role by regulating enzyme activity.
5. Tomato extract: It has strong antioxidant and anti-inflammatory activities. Tomatoes are rich in phytochemicals, such as carotenoids (lycopene, phytoene and β-carotene) and polyphenols (flavonoids, flavanones and flavonoids), which can resist oxidative stress and inflammation and contribute to potential health benefits and overall well-being.
6. Alpha lipoic acid: It is often called "universal antioxidant" and plays a role in aqueous and lipophilic environments. It enhances the expression of antioxidant enzymes, helps vitamin recovery, and has anti-inflammatory properties. Clinical studies on humans and animals show that it has potential benefits for cardiovascular diseases, obesity, inflammation, pain and aging.
7. Turmeric extract: curcumin is a pigment in turmeric, which has antioxidant and anti-inflammatory properties. Its preventive and therapeutic effects are related to the damage caused by free radicals in cancer, atherosclerosis and neurodegenerative diseases. The anti-inflammatory effect of curcumin involves the inhibition of key enzymes such as COX-2, LOX and iNOS, thus providing potential chemoprevention for cancer and inflammatory diseases.
8. Shatavari extract: asparagus racemosus, commonly known as Shatavari or Rak-Sam-Sib, belongs to Liliaceae. It exists in the shadow areas of Asia, Australia and Africa and contains steroidal saponins, including Satava I-IV. Asparagus racemosus root extract shows a variety of pharmacological activities, such as anti-ulcer, anti-oxidation, immunomodulation and anti-aging, which makes it beneficial to treat neurological disorders, dyspepsia, diarrhea, tumors and inflammation.
