• Artichoke

Artichoke (scientific name: Cynara scolymus L.) is a perennial herb of the family Compositae, Artichoke genus, up to 2 meters high. Stems stout, erect, with branches at the upper part, large leaves, rosette-like basal leaves; lower stems and leaves elliptic or broadly lanceolate, about 1 m long, bipinnatifid, with long petioles; texture of all leaves Thin, herbaceous, green above, gray-white below, large capitulum, multi-layered involucral buds, glabrous, imbricate arrangement, attached to dura mater, round, ovate, triangular or caudate, florets purple-red , the corolla lobes are 9 mm long. Achenes oblong, without margins. The crested white, blooms and bears fruit in July.

It is native to the Mediterranean region and cultivated in Western Europe. It is used as a vegetable. It eats the fleshy receptacle and the fleshy part of the base of the involucral bracts, and its nutritional value is also excellent. It contains substances such as artichoke, asparagine and flavonoids, and is a precious health vegetable with high nutritional value.

The main edible parts of artichoke are the fat and tender bracts of the flower buds (like lily scales) and the fleshy receptacle. It contains substances such as artichoke, asparagine and flavonoids. It is a precious health vegetable with high nutritional value. It is known as the “king of vegetables”. Regular consumption can protect liver and kidney, enhance liver detoxification, and promote digestion. , Improve blood circulation, prevent arteriosclerosis, protect cardiovascular efficacy.

The edible part of the artichoke curd contains a variety of nutrients, high protein, calcium and phosphorus content, and also contains more inulin (higher content in the root). Functional compounds such as polyphenols and flavonoids such as artichoke acid and chlorogenic acid exist not only in curds, but also in leaves.

  • Artichoke Extract

Artichoke extract, also known as artichoke extract, the main specifications are 5% artichoke (UV, detection), 2.5% artichoke acid (HPLC), 5% artichoke (HPLC detection, artichoke acid and chlorogenic acid) total content).

Benefits: Treat indigestion, lower blood lipids and anti-atherosclerosis, protect liver and antioxidant functions, prevent the occurrence of cardiovascular diseases with antimicrobial effect, anti-spasmodic, improve intestinal peristalsis, promote intestinal wall contraction, and make the substances in the intestines more effective Fast delivery, thus preventing constipation.

  1. Antioxidant effect

Artichoke leaf extract is anti-oxidative and protects mouse liver from oxidative stress from hydrogen peroxide, as well as lowers low-density lipoprotein (LDL). Using the scavenging effect of each polyphenolic compound isolated from artichoke extract on DPPH free radicals to evaluate their antioxidant capacity, it was found that the antioxidant capacity of polyphenolic compounds was mainly determined by the number of hydroxyl groups on the aromatic ring, The higher the number of hydroxyl groups, the stronger the antioxidant capacity. In addition, the second hydroxyl groups located in the ortho and para positions can also increase its antioxidant capacity.

  1. Protect the liver

Artichoke root can be used as medicine, has the functions of sterilization, hangover, stimulates bile secretion, etc. It is very effective for liver damage caused by alcohol.

  1. Antimicrobial activity

The chlorogenic acid, artichoke acid, luteolin-7-rutinoside and artichoke glycoside of the artichoke extract have relatively high antimicrobial activities, and the antifungal activity is stronger than the antibacterial activity. Studies have reported that artichoke leaf extract has obvious resistance to 7 kinds of bacteria, 4 of which are yeasts.

  1. Lower cholesterol

Artichoke extract can regulate human lipid metabolism by lowering cholesterol and endogenous triglycerides in human body. Bile is the main way to eliminate cholesterol, artichoke extract can reduce the cholesterol content in human liver and serum by promoting the secretion of bile. At the same time, there are also many studies showing that artichoke extract can directly act on the synthesis of endogenous cholesterol.

  1. Treats Indigestion

The mechanism of artichoke extract in the treatment of indigestion is to promote the secretion of bile, and artichoke extract can be used to treat digestive system disorders, accompanied by insufficiency of bile secretion.

  1. Lowering blood lipids and anti-atherosclerosis

Studies have shown that artichoke extract can reduce blood lipids, mainly by affecting the synthesis and decomposition of cholesterol and lipids in the liver to regulate lipid levels. In a double-blind trial, 44 healthy people were randomly divided into groups, and after taking artichoke extract, one group’s cholesterol level was significantly lower than the control group. The effect was more pronounced in people with high total cholesterol. However, high-density lipoprotein (HDLS), which is beneficial to health, has a tendency to increase, and can inhibit the oxidation of harmful low-density lipoprotein (LDLS), thereby preventing the occurrence of atherosclerosis.

  1. Regulation of endothelial cell function

Endothelial cell dysfunction is the early stage of atherosclerosis, and blood flow-mediated vasodilation (FMV), vascular cell adhesion molecule-1 (VCAM-1), and intercellular adhesion molecule-1 are often measured by ultrasound. (ICAM-1) and E-selectin and other humoral markers. Foreign researchers observed the effect of artichoke juice food additives on arm FMV in patients with hyperlipidemia, measured the basal levels of soluble VCAM-1, ICAM-1, E-endothelial cell selectin (selectin) in serum and arm FMV, and found that taking After artichoke, patients’ triglyceride level increased, total cholesterol and LDL cholesterol decreased; total cholesterol and LDL cholesterol were significantly decreased in control group, VCAM-1, ICAM-1 and arm FMV in treatment group were decreased compared with those before treatment, while control group There was no change before and after treatment in the group. It can be seen that artichoke food additives can indeed regulate endothelial function in patients with hypercholesterolemia.

  1. Other functions

Artichoke leaf extract, especially the flavonoids in it, can regulate the gene expression of NO enzyme in human epithelial cells and promote the synthesis of NO, thereby preventing the occurrence of cardiovascular diseases. Artichoke bitters contained in artichokes have antispasmodic properties. In addition, artichoke can improve peristalsis, promote intestinal wall contraction, so that the substances in the intestine can be transported faster, thereby preventing constipation. Artichokes contain a large amount of inulin. Inulin is a fructan formed from D-fructofuranose molecules connected by β-(2-1) glycosidic bonds, which can increase the synthesis of B vitamins and improve human immunity. Function; At the same time, inulin can promote the absorption and utilization of trace elements iron and calcium, which can prevent osteoporosis and reduce liver toxins, especially aminotoxins. Inulin can generate anti-cancer organic acids in the intestine, which has a significant anti-cancer function; it has the effect of reducing food allergies and rejection; it is suitable for diabetics.

  • Artichoke Prospects

Artichoke is rich in phenols, flavonoids, terpenoids and other chemical components, and has more significant physiological functions, such as antioxidant, liver protection, cholesterol lowering, antibacterial, and stomach improvement. With the increasing development of artichoke medicinal value in modern medicine and the improvement of people’s awareness of artichoke health care functions, the demand for artichoke tea bags, artichoke health food, artichoke dry powder and artichoke extract is also increasing. Gradually increase. It has great development potential in the application of health food, which can be used in brewing, tea making and other industries. The extract can be used in food additives, feed additives, antioxidants and even medicines; as a new type of vegetable, artichoke has been gradually Accepted by some processing enterprises in my country, and began to carry out deep processing research and development of artichoke corresponding by-products; artichoke leaves and other by-products have unique disease prevention and health care effects, and can develop artichoke tea, functional beverages, health products, and livestock functions with independent intellectual property rights. feed, etc. It can be seen that artichoke has a broad space for development.
