Perilla has high nutritional value and is a fashionable vegetable and health product. Do you know the useful value of perilla?
1. The oil value
The oil content of perilla seeds is high, and the oil yield can reach 40% to 50%. Among them, the content of α-linolenic acid is as high as 50%~70%, which is the highest content in natural plants found so far. Alpha-linolenic acid is an omega-3 fatty acid, which cannot be synthesized by the human body and must be obtained from food. Alpha-linolenic acid can be metabolized in the body to produce EPA and DHA. EPA is the precursor of triene prostaglandins in the body, and DHA is the main component of phospholipids in the nervous system membranes such as the brain and retina. It can not only improve the function of the nervous system, but also play a role in improving learning and memory. In addition, α-linolenic acid also has various effects such as promoting immunity, reducing blood lipids, and preventing the occurrence of cardiovascular and cerebrovascular diseases. The oil value of perilla is mainly reflected in the function of edible health care.
2. Medicinal value
2.1 Antibacterial and antiviral efficacy. The essential oil of perilla leaves is effective against gram-positive and gram-negative bacteria
Strong antibacterial effect; Perilla stem and leaf extract also has inhibitory effect on common bacteria.
2.2 Hemostatic effect. Perilla leaf extract can directly act on blood vessels to promote the formation of platelet thrombus. After the thrombus is formed, it can mechanically block the wound, thereby achieving the effect of hemostasis and shortening the blood coagulation time and plasma recalcification time.
2.3 Antioxidant effect. Rosmarinic acid from Perilla frutescens has strong reducing power and antioxidant properties, and has an inhibitory effect on the oxidative damage of deoxyribose. Its antioxidant activity is higher than that of ascorbic acid.
2.4 In addition, Perilla also has various effects such as lowering blood lipids, anti-allergic, sedative, analgesic, and improving immunity.
