Introduction for Portulaca oleracea extract skin care
Portulace oleracea L. is an annual succulent herbaceous plant native to temperate and tropical regions. It is distributed in the north and south except in the alpine region of China. Portulaca oleracea extract skin care contains polysaccharides, flavonoids, polyphenols, alkaloids and other biologically active substances, which can remove free radicals from the body and have long-lasting effects on the human body. Therefore, it is also known as longevity and longevity.
Efficacy of polysaccharides
Polysaccharides are polymers formed by monosaccharides linked by glycosidic bonds. They are widely found in plants, animals, bacteria, fungi and seaweeds and are an important class of active substances. In the 1940s, humans discovered that fungal polysaccharides have anti-cancer effects. Later studies have shown that polysaccharides also have various biological functions such as immune regulation and anti-inflammatory, and have the advantages of low toxic and side effects and difficulty in causing residues, and are known as biological response modifiers.
Ultrasonic extraction of polysaccharides from roots, stems, leaves and flowers of Portulaca oleracea extract skin care was carried out to study the polysaccharide content and antioxidant activity of different organs of Portulaca oleracea extract skin care The polysaccharide yield of Portulaca oleracea extract skin care was the highest, reaching 7.65%. When the concentration of polysaccharide extract of leaves was 9 mg/mL and 10 mg/mL, the scavenging ability of hydroxyl radical and superoxide anion radical was the strongest. 91.42% and 78.02%, respectively, the root polysaccharide extract concentration of 10 mg / mL, the DPPH free radical scavenging ability is the strongest, the clearance rate reached 99.41%, the polysaccharide extract reducing ability is the root, in the polysaccharide The reduction capacity reached a maximum of 0.80 at a concentration of 5 mg/mL. In different free radical systems, polysaccharide extracts from different parts of Portulaca oleracea extract skin care had good scavenging effect and strong reducing ability, and their antioxidant effects and mass concentration of polysaccharide extracts were significant. Effective relationship.
