What Are The Effects Of Loquat Leaf Extract?

Antibacterial

Ethyl acetate extract and ethanol extract of loquat leaves have inhibitory effects on Staphylococcus aureus, Staphylococcus albus, hemolytic streptococci, pneumococcus, catarrhalis, etc. Oleanolic acid has different degrees of antibacterial effects on Staphylococcus aureus, hemolytic streptococci, Escherichia coli, Shigella flexneri, Salmonella typhi, Salmonella choleraesuis, etc.

Antioxidant

Loquat Leaf Extract also has antioxidant effects, can protect the liver, detoxify, and has a protective effect on acute and chronic hepatitis damage.

Antitussive and expectorant

Amygdalin is decomposed into hydrocyanic acid and benzaldehyde by gastric acid or amygdalin. After absorption, it inhibits cytochrome oxidase and inhibits the oxidative metabolism of the common carotid body, which reflexively deepens breathing, has a sedative effect on the respiratory center, and makes respiratory movements tend to be quiet to achieve the effect of antitussive and antiasthmatic. Loquat leaf decoction and its ethyl acetate extract have antiasthmatic and expectorant effects. Saponins have the effect of inducing bronchial mucosal secretion and have expectorant effects when taken orally. Caffeic acid has antitussive and expectorant effects.

Hypoglycemic effect

Triterpene acids and sesquiterpene compounds isolated from loquat leaf methanol extract have a significant hypoglycemic effect on diabetic mice. The mechanism of action may be to stimulate pancreatic B cells and increase the release level of insulin, thereby achieving the effect of lowering blood sugar.

Protecting the liver and lowering blood lipids

Oleanolic acid in loquat leaves has liver protection and detoxification effects, and can have a significant protective effect on acute and chronic hepatitis damage caused by CCl4. It significantly reduces the activity of alanine aminotransferase and aspartate aminotransferase, and can prevent the occurrence of experimental cirrhosis.

Immunomodulation

Using cyclophosphamide (Cy) to induce immunosuppression model in mice, carbon clearance test, hemolytic plaque test, delayed hypersensitivity reaction induced by dinitrofluorobenzene (DNFB) and determination of T lymphocyte subsets, the effects of loquat leaf triterpene acid (TAL) on nonspecific immunity, humoral immunity and cellular immunity of immunosuppressed mice were observed. The results showed that TAL has a good immunomodulatory effect.

Stomach-reducing and vomiting-stopping

Loquat leaves can relieve heat, reduce qi and reverse, and are a good product for stopping vomiting. They can treat various vomiting and hiccups.

Expectorant and cough-relieving

The hydrocyanic acid produced by the hydrolysis of amygdalin contained in loquat leaves in the body has a cough-relieving effect, which can effectively reduce the occurrence of common respiratory diseases such as dry cough and tracheitis.

Anti-inflammatory and sedative

In addition to the basic pharmacological activity, loquat leaves also contain one of the active ingredients, amygdalin, which can be decomposed into cyanic acid and benzaldehyde after absorption, and can play a strong anti-inflammatory and analgesic effect.

Improve skin

It has a significant protective effect on the skin. It contains rich trace elements and vitamins, which can reduce inflammation and calm the skin, and can also improve inflammation.

Liver protection and detoxification

Oleanolic acid has hepatoprotective and detoxifying effects, and can significantly protect against acute and chronic hepatitis damage caused by CCl4. It significantly reduces the activities of alanine aminotransferase and aspartate aminotransferase, and can prevent the occurrence of experimental cirrhosis.

Enhance physical fitness

It allows the body to absorb rich vitamins, amino acids, and a variety of natural minerals. They can meet the body's metabolic needs for different nutrients, improve the body's immunity, and are of great benefit to enhancing physical fitness.

What Are The Ingredients Of Loquat Leaf Extract?

The main ingredients of Loquat Leaf Extract include ursolic acid, flavonoids (such as apigenin, apigenin, apigenin-7-O-acetylglucoside), carotenoids (such as β-carotene, α-carotene, zeaxanthin, zeaxanthin palmitate), ursolic acid, amygdalin, total triterpene acids (such as 2α-hydroxyoleanolic acid), saponins, organic acids, etc. Among them, ursolic acid, also known as ursolic acid, ursolic acid, belongs to triterpene compounds. Ursolic acid has obvious antioxidant function, so it is widely used as a raw material for medicine and cosmetics. It can lower blood lipids, blood pressure, and resist atherosclerosis; it can increase coronary blood flow, improve coronary circulation, and compensate for coronary failure, thereby achieving a cardiotonic effect, and increasing the sensitivity of the myocardium to cardiotonic effects, increasing cardiac output, reducing myocardial irritability and conductivity, and has the effects of resisting ventricular fibrillation, atrial fibrillation and paroxysmal arrhythmia, and restoring the beating of a fatigued heart.

What Are The Benefits Of Loquat Leaf Extract For The Skin?

Skin conditioner: Loquat Leaf Extract is mainly used as a skin conditioner in cosmetics and skin care products. It has sedative, anti-inflammatory, antibacterial effects, as well as obvious antioxidant effects.

Prevent skin problems: Cosmetics containing loquat leaf extract can prevent prickly heat and rashes on the skin surface and skin inflammation.

Suitable for a variety of skin types: Loquat Leaf Extract ingredients are suitable for wrinkled skin, dry skin, non-pigmented skin, tolerant skin, pigmented skin, sensitive skin, oily skin and firm skin.

Skin care effect: Loquat leaf bathing can make people feel smooth blood circulation, and has a good effect on eliminating skin inflammation such as prickly heat and rashes.

Prevent colds and vomiting: Loquat Leaf Extract can also prevent influenza because it contains a variety of natural antiviral ingredients that can inhibit the activity of influenza viruses.

Enhance physical fitness: Through skin absorption, Loquat Leaf Extract allows the body to absorb rich vitamins and amino acids, as well as a variety of natural minerals, to meet the body's metabolic needs for different nutrients and improve the body's immunity.

What Effect Does Loquat Leaf Extract Have On Immunity?

Enhance the body's immunity: Loquat Leaf Extract can enhance the body's immunity. It is slightly cold in nature, can clear the heat and toxins in the body, and has a certain relieving effect on stomach heat, thereby helping to improve symptoms such as nausea, vomiting and regurgitation caused by stomach heat, and help improve the body's immunity.

Antiviral effect: The antiviral activity of loquat leaf extract is also related to immunity. For example, loquat leaf extract has low cytotoxicity to multiple cell lines, and exerts antiviral activity by inducing cell apoptosis, with less effect on normal cells. This may help improve the body's resistance to viral infections.

Anti-inflammatory and antibacterial effects: Loquat leaf extract also has anti-inflammatory and antibacterial effects, which may indirectly enhance the body's immune response. For example, loquat leaf extract has been found to have an inhibitory effect on Staphylococcus aureus, Staphylococcus albus, hemolytic Streptococcus, Pneumococcus, etc.

Regulating the body's immune function: The pharmacological effects of loquat leaf extract also include regulating the body's immune function. Although the specific mechanism is not detailed in the search results, regulating immune function is an important aspect of improving immunity.
