Rheum tanguticum Maxim. ex Balf. (RT), mainly is mainly produced in Gansu, Qinghai, Tibet and Sichuan of China, has long been used as a medicine for purging fire and quenching thirst. The RTR-2 (Rheum tanguticum root extract without polysaccharides and protein) had strong inhibitory activities against a-amylase, maltase and sucrase with the IC50 0.042 mg/mL, 0.124 mg/mL and 0.097 mg/mL, resp. In addition, RTR-2 could significantly reduce PBG level of diabetic mice in starch/maltose/sucrose tolerance test. Total 48 constituents including 12 anthraquinones, 4 bianthrones, 8 flavans, 3 stilbenes, 5 phenylbutanones, 4 naphthosides, 8 glucose gallates and 4 phenolic acids were determined in RTR-2 by UPLC-Triple-TOF/MS anal. of mol. ion, main fragments, retention time, and references Furthermore, the components such as flavan ((-)-epicatechin 3-O-gallate) and phenylbutanone (lindleyin) were demonstrated to have sucrase and maltase inhibitory activites, and might be the main hypoglycemic active ingredients of RTR-2 extract All these results offered an exhaustive knowledge for the hypoglycemic compounds of Rheum tanguticum, which was conducive to its further development and utilization as a valuable source of hypoglycemic plant in pharmaceutical industry. This study involved multiple reactions and reactants, such as (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6Recommanded Product: 27208-80-6).
(2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Recommanded Product: 27208-80-6
