Salacinol, potent antidiabetic principle with unique thiosugar sulfonium sulfate structure from the Ayurvedic traditional medicine Salacia reticulata in Sri Lanka and India
A most potent natural α-glucosidase inhibitor named salacinol has been isolated from an antidiabetic Ayurvedic traditional medicine, Salacia reticulatawight, through bioassay-guided separation. The… Expand
Phenylethanoid oligoglycosides and acylated oligosugars with vasorelaxant activity from Cistanche tubulosa.
The methanolic extract from the dried stems of Cistanche tubulosa (Schrenk) R. Wight was found to show an inhibitory effect on contractions induced by noradrenaline in isolated rat aortic strips.… Expand
Isolation, structure identification and SAR studies on thiosugar sulfonium salts, neosalaprinol and neoponkoranol, as potent α-glucosidase inhibitors.
Two hitherto missing members of sulfonium salts family in Salacia genus plants as a new class of α-glucosidase inhibitors, neoponkoranol (7) and neosalaprinol (8), were isolated from the water… Expand
Acylated phenylethanoid oligoglycosides with hepatoprotective activity from the desert plant Cistanche tubulosa.
The methanolic extract from fresh stems of Cistanche tubulosa (Orobanchaceae) was found to show hepatoprotective effects against D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced liver injury… Expand
Bioactive constituents from Chinese natural medicines. XXII. Absolute structures of new megastigmane glycosides, sedumosides E1, E2, E3, F1, F2, and G, from Sedum sarmentosum (Crassulaceae).
TLDR
Six new megastigmane glycosides, sedumosides E1, E2, E3, F1, F2, and G, were isolated from the whole plant of Sedum sarmentosum (Crassulaceae) on the basis of chemical and physicochemical evidence. Expand
Megastigmanes and their glucosides from the whole plant of Sedum sarmentosum.
TLDR
The absolute stereostructures of 1-8 were elucidated on the basis of chemical and physicochemical evidence, including the application of the modified Mosher's method. Expand
Quantitative determination of potent alpha-glucosidase inhibitors, salacinol and kotalanol, in Salacia species using liquid chromatography-mass spectrometry.
TLDR
The results indicated that the HPLC-MS method was reproducible and precise and could be readily utilized for the evaluation of Salacia species and showed good linearity within test ranges. Expand
Perennisosides I-VII, acylated triterpene saponins with antihyperlipidemic activities from the flowers of Bellis perennis.
The methanolic extract and its saponin fraction (methanol-eluted fraction) of the flowers of Bellis perennis were found to suppress serum triglyceride elevation in olive oil-treated mice. From the… Expand
Medicinal foodstuff. III. Sugar beet. (1): Hypoglycemic oleanolic acid oligoglycosides, betavulgarosides I, II, III, and IV, from the root of Beta vulgaris L. (Chenopodiaceae).
Betavulgarosides I, II, III, and IV, oleanolic acid oligoglycosides having an unique acidic substituent, were isolated from the root of Beta vulgaris L. (sugar beet) together with betavulgarosides… Expand
Mangiferin suppresses CIA by suppressing the expression of TNF-α, IL-6, IL-1β, and RANKL through inhibiting the activation of NF-κB and ERK1/2.
TLDR
Mangiferin suppressed the progression and incidence of CIA in DBA1/J mice and markedly inhibited not only developing but also clinically evident CIA, suggesting that mangiferin has potential clinical applications for the treatment of rheumatoid arthritis. Expand
