Two acylated anthocyanins from purple sweet potato
Phytochemistry, 1997Two new acylated anthocyanins were isolated from the storage root of Ipomoea batatas. On the basis of spectroscopic analyses, these compounds were identified as the 3-O-(6-O-trans-caffeyl-2-O-beta-glucopyranosyl-beta-glucopyranoside)-5-O - beta-glucoside of cyanidin and peonidin.

Preparation and antioxidant activity of phosphorylated polysaccharide from purple sweet potato
Chemical Biology & Drug Design, 2021AbstractPurple sweet potato polysaccharide was extracted via hot water, and it was chemically modified by phosphorus oxychloride‐pyridine to obtain phosphorylated polysaccharide from purple sweet potato (P‐PPSP) with certain degrees of substitution. Furthermore, the structure and antioxidant activity in vitro of PPSP and phosphorylated derivative were ...

Immune-enhancing effects of polysaccharides from purple sweet potato
International Journal of Biological Macromolecules, 2019Immune-enhancing effects of three kinds of purple sweet potato polysaccharides (PSPPs) including water-soluble polysaccharide (WSP), dilute alkali-soluble polysaccharide (DASP) and concentrated alkali-soluble polysaccharide (CASP) were evaluated. Scanning electron microscope analysis showed that all PSPPs could stimulate the formation of microvilli ...

Sweet potato (Ipomoea batatas L.) is an extremely important crop in many parts of the world, being cultivated in more than 100 countries. In Malaysia, sweet potato is the second crop after cassava (Manihot esculenta crantz). In this study, the effect of several Malaysian purple sweet potato varieties (K2, K5 and K6) on physical and chemical ...

Destabilisation and stabilisation of anthocyanins in purple-fleshed sweet potatoes: A review
Trends in Food Science & Technology, 2021Abstract Background As a category of natural colourants, anthocyanins are abundant in purple-fleshed sweet potato (PFSP). Recently, anthocyanins from PFSP are proven to have multiple bioactivities, but they are liable to undergo discolouration and degradation upon thermal treatment, light exposure, oxidation, etc.

Integrating consumer perception in the selection of purple‐skin sweet potato cultivars
Journal of the Science of Food and Agriculture, 2020AbstractBACKGROUNDSweet‐potato breeding programs need to integrate sensory characterization and hedonic perception to provide global markets with widely accepted products. The present work aimed to characterize a series of purple‐skin sweet potatoes differing in flesh coloration (from pale yellow to slight orange) from a sensory and physicochemical ...

Characterization, antioxidant and antitumor activities of polysaccharides from purple sweet potato
Carbohydrate Polymers, 2015Three polysaccharides, PSPP1-1, PSPP2-1 and PSPP3-1, were isolated from purple sweet potato. The three polysaccharides belonged to β-type polysaccharides and contained low proportions of proteins and uronic acids. PSPP1-1 and PSPP3-1 with molecular weights of 33.3 and 75.3 kDa, respectively, were composed of rhamnose, xylose, glucose and galactose ...

Direct Absorption of Acylated Anthocyanin in Purple-Fleshed Sweet Potato into Rats
Journal of Agricultural and Food Chemistry, 2002Absorption of acylated anthocyanins in purple-fleshed sweet potato (Ipomoea batatas cv. Ayamurasaki) in rats was studied to obtain evidence that the acylated anthocyanins themselves could exert a physiological function in vivo. Peonidin 3-caffeoylsophoroside-5-glucoside (Pn 3-Caf*sop-5-glc) in purple-fleshed sweet potato was directly absorbed into rat ...
