1. Introduction to Celery Extract
Celery extract is mainly derived from celery (Apium graveolens), which is a plant of the genus Apiaceae. Celery is divided into celery and water celery, and the raw materials for extraction are generally celery stems and leaves. Celery stems are cylindrical, with longitudinal ridges, and the leaves are pinnate.
Celery extract contains a variety of chemical components. Among them, flavonoids are relatively rich, such as apigenin and luteolin. Flavonoids have multiple biological activities such as antioxidant and anti-inflammatory. It also contains phenolic acid compounds, such as ferulic acid and chlorogenic acid, which play an important role in antioxidant and physiological function regulation. In addition, celery extract contains volatile oil components, mainly including limonene, butylphthalide, etc. These volatile oil components can play a role in seasoning and certain physiological regulation. At the same time, celery extract also contains a variety of vitamins (such as vitamin K, vitamin C, etc.) and minerals (such as potassium, calcium, magnesium, etc.).
2. Efficacy of Celery Extract
Antioxidant efficacy
Flavones and phenolic acid compounds in celery extract are the main antioxidant components. These components can remove free radicals in the body, such as superoxide anion free radicals, hydroxyl free radicals, etc. Free radicals can cause oxidative damage to cells, causing cell aging, inflammation and various diseases. For example, apigenin can neutralize free radicals by providing hydrogen atoms, thereby reducing the damage of free radicals to cells, protecting biological macromolecules such as lipids, proteins and DNA of cells, and helping to delay the aging process and prevent chronic diseases.
Anti-inflammatory effect
Celery extract can reduce inflammatory response. On the one hand, it can inhibit the production of inflammatory factors, such as interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), etc. These inflammatory factors play a key mediating role in the inflammatory process, attracting immune cells to the inflammatory site and promoting the release of inflammatory mediators. On the other hand, celery extract can regulate inflammation-related signaling pathways, such as the inhibition of the nuclear factor-κB (NF-κB) signaling pathway, thereby reducing the expression of inflammation-related genes and alleviating inflammatory symptoms. In animal experiments, the symptoms of redness, swelling, heat and pain in the inflammatory area of the inflammatory model animals treated with celery extract were significantly reduced.
Effect on lowering blood pressure
Celery extract has a positive effect on blood pressure regulation. Ingredients such as apigenin and butylphthalide may be the key factors in its antihypertensive effect. These ingredients can lower blood pressure by relaxing vascular smooth muscle and reducing peripheral vascular resistance. At the same time, celery extract has a high potassium content, which can promote the excretion of sodium, reduce sodium and water retention in the body, and also help lower blood pressure. In the hypertensive animal model, blood pressure showed a significant downward trend after celery extract was given.
Improve digestive function
The volatile oil components in celery extract can stimulate gastric juice secretion, and gastric acid and pepsin in gastric juice help digest food. At the same time, the dietary fiber components in celery extract can promote gastrointestinal motility, help food move in the gastrointestinal tract, and prevent digestive problems such as constipation. Moreover, celery extract can also regulate intestinal flora, provide favorable conditions for the growth of beneficial bacteria, inhibit the growth of harmful bacteria, and improve the intestinal microecological environment.
Nerve protection
Certain ingredients in celery extract have a protective effect on the nervous system. For example, apigenin can reduce oxidative stress and inflammatory damage to nerve cells through antioxidant and anti-inflammatory effects. At the same time, vitamin K in celery extract may have a certain effect on the development and functional maintenance of the nervous system. It can participate in the synthesis of sphingolipids and help the transmission of nerve signals.
3. Application of Celery Extract
Medical field
In terms of pharmaceutical preparations, celery extract can be used to make auxiliary ingredients of antihypertensive drugs to enhance the antihypertensive effect of drugs. It can also be used to make anti-inflammatory drugs and assist in the treatment of inflammation-related diseases. In addition, due to its protective effect on nerves, it can also be used to make drugs or health products for the treatment of nervous system diseases (such as neurodegenerative diseases).
Food industry
Celery extract is a natural food additive. It can be added to food as a spice, and its volatile oil components can be used to improve the flavor of food. At the same time, due to its antioxidant and blood pressure lowering effects, it can also be added to functional foods, such as adding celery extract to some health foods to help consumers control blood pressure and prevent chronic diseases.
Cosmetics field
The application of celery extract in cosmetics is mainly based on its antioxidant and anti-inflammatory effects. It can be added to skin care products such as creams, lotions, essences, etc. to protect the skin from free radical damage, delay skin aging, reduce skin inflammation, and make the skin healthier and more lustrous.
