sphallerocarpus gracilis/抗酸化物質

Sphallerocarpus gracilis roots harvested at two different times (T1: 12-10-2009 and T2: 15-04-2010) were analysed for their main nutrients, phenolics, antioxidant activity, DNA damage protective effect and microstructure. Results revealed that higher amounts of starch were detected in T1 S. gracilis

Sphallerocarpus gracilis (S. gracilis) is a little-investigated edible plant and used as traditional Chinese medicine. In this study, polysaccharide extracted from S. gracilis,deproteined and purified. The polysaccharide (SGP) was chemically modified to obtain its sulfated derivatives (S-SGP) using

The extraction process of Sphallerocarpus gracilis root polysaccharides (SGRP) was optimized using response surface methodology with two methods [hot-water extraction (HWE) and ultrasonic-assisted extraction (UAE)]. The antioxidant activities of SGRP were determined, and the structural features of

An efficient preparative separation method for Sphallerocarpus gracilis stems and leaves polyphenols (SGslP) was established in this study. An X-5 macroporous adsorption resin was selected for the purification of the SGslP, and the polyphenol content of the purified SGslP (PSGslP) was increased

In the present study we evaluated the free radical scavenging action of some medicinal herbs growing in Mongolia. The aqueous extract of nine herbs Chamenerion angustifolium (Ch.ang), Equisetum arvense (Eq.arv), Gentiana decumbens (Gn.dec), Geranium pratense (Gr.pra), Lomatogonium carinthiacum
