Extraction and bioactivity of polygonatum polysaccharides

Optimization of Alkaline Extraction and Bioactivities of Polysaccharides from Rhizome ofPolygonatum odoratum

“…Under the optimal condition, the extraction was repeated and the actual yield was 17.28% ( n = 3). Jiang et al [12] reported that the yield of polysaccharides using hot water extraction (extraction times = 4) was about 14.2%, and Lan et al [1] reported that its yield using hot water extraction assisted by ultrasound (extraction times = 3) was 15.15%. The yield of alkaline extraction from P. odoratum was higher than that of hot water extraction.…”

“…Extraction of polysaccharides from P. odoratum is an important approach to further research or scale application. Tomshich et al [11] reported extraction and purification of polysaccharides from ten medicinal plants including P. odoratum , and several reports were documented on extraction and bioactivities of polysaccharides from P. odoratum in recent years [1, 12]. Generally, researches were focused on the study of extraction of neutral soluble polysaccharides from P. odoratum , using hot water extraction or hot water extraction assisted by physical technologies such as microwave and ultrasound, to optimize the productivity of polysaccharides.…”

Application of Box–Behnken design for ultrasonic-assisted extraction of polysaccharides from Paeonia emodi

“…They may be amorphous or even water insoluble [1]. Several therapeutic effects of polysaccharides has been described including anti-tumor [2], anti-oxidant [3], immunomodulatory [4,5] anti-diabetic and antiviral activities, and nearly bearing no adverse effects on human body have been reported [6].…”

Antioxidant and protective effect of inulin and catechin grafted inulin against CCl4-induced liver injury

“…Recently, increasing evidence has highlighted that oxidative stress is involved in the pathogenesis and progression of hepatic injury [3,4]. Accordingly, several natural polysaccharides with antioxidant property have been demonstrated to possess potent hepatoprotective effect against various chemicals induced injury [5][6][7][8].…”
