Rubusoside (the beta-D-glucosyl ester of 13-O-beta-D-glucosyl-steviol), which is the major sweet principle of leaves of Rubus suavissimus S. Lee, was subjected to 1,4-alpha-transglucosylation by the cyclodextringlucanotransferase-starch system (the CGTase system). The tri- and tetra-glucosylated
Drinking an herbal tea to lose weight is a well-liked concept. This study was designed to examine the possible improvement of obesity phenotype by a new tea represented by its purified components, gallic acid, ellagic acid, and rubusoside (GER). Male obese-prone SD rats were given low-fat diet,
The quality of botanical food is increasingly assessed by the content of multiple bioactive compounds. This study reports, for the first time, an HPLC fingerprinting method for the quality evaluation of Rubus suavissimus leaves possessing multiple bioactivities. Five constituents, gallic acid,
Chronic exposure to minute doses of endotoxin elicits intestinal inflammation and impairs the gut barrier function, potentially resulting in systemic inflammation with elevated concentrations of biomarkers associated with metabolic syndrome. This study aimed to investigate the preventive effects of
The aqueous extraction process of the leaves of Rubus suavissimus often brings in a large amount of nonactive polysaccharides as part of the constituents. To purify this water extract for potential elevated bioactivity, an alcohol precipitation (AP) consisting of gradient regimens was applied, and
