At present, GC-MS analysis of garlic skin chemical composition has not been reported. In this paper, the chemical composition of garlic skin extract is analyzed for the first time. The main component of garlic skin extract is fatty acid, showing that garlic skin fatty acid mainly contains even carbon Of fatty acids (content 69.74%), and the content of odd carbon fatty acids is very low (2.83%), indicating that the fatty acids in garlic skin have high nutritional value.
Plant fatty acids
Plant fatty acids have a variety of pharmacological activities, mainly including lowering blood pressure, lowering blood fat, anti-cardiovascular disease, and promoting growth and development.
Linoleic acid and its esters are the main fatty acids in garlic skin, accounting for 23.12% of the total fatty acids. Linoleic acid is an essential fatty acid for the human body. It has the functions of lowering cholesterol in the blood, lowering blood fat, preventing atherosclerosis, and resisting breast cancer. Active, helps the normal metabolism of body fat and cholesterol, thereby preventing the occurrence of cardiovascular diseases.
The study found that volatile oils mainly composed of myristic acid, palmitic acid, and lauric acid have antibacterial activity in vitro. These three components may also be one of the medicinal components of garlic skin antibacterial effect.
In addition, garlic skin also contains a thioether compound-diallyl trisulfide, this thioether compound is the main active ingredient contained in garlic, with antibacterial anti-inflammatory, anti-viral, anti-tumor, enhanced Immunity and other effects. This ingredient may be one of the medicinal ingredients of garlic skin.
Phytosterol is a Chinese medicine that can lower cholesterol in the blood and regulate blood lipids. It has pharmacological activities such as cancer prevention, prostate disease prevention, anti-inflammatory and anti-viral, and anti-viral. One.
The study found that the main component of garlic volatile oil is sulfide compounds, and also contains a small amount of fatty acids.
It mainly has antibacterial and anti-inflammatory, lowers blood pressure, lowers blood fat, inhibits platelet aggregation, prevents cancer, and enhances immunity.
Medicinal value and nutritional value.We found that the medicinal and edible value of garlic and garlic skin is mainly due to the mixed ingredients, but their main ingredients are different.
The main function of garlic is reflected in its medicinal value, and the main function of garlic skin is reflected in Its edible value, therefore, reasonable and full use of garlic and garlic skin has important practical significance.
