The quant. anal. of trace resveratrol and polydatin in plant tissues is suitable for elucidation of the compounds mechanisms of action. The main objective of this work was to develop a feasible and effective sample pretreatment method to measure the concentrations of resveratrol and polydatin in complex samples. A polymer sorbent, poly(2-mercaptobenzimidazole), was electrochem. prepared and utilized for selective extraction, while resveratrol and polydatin were used as target analytes. The sorbent was characterized by cyclic voltammetry, SEM and Fourier transform IR spectroscopy. After extraction and elution, the analytes were analyzed by a Thermo U3000 HPLC system. Several affecting parameters, including the volume of elution solution, sample pH value, sample flow rate and sample volume, were evaluated and optimized. The proposed method showed good linearity with low limits of detection (from 0.5 to 0.8 ng·mL-1) and ideal accuracy with spiked recoveries from 81.30% to 99.16%. A good enrichment factor (more than 200-fold) together with good sensitivity was obtained with this method. Anal. of resveratrol and polydatin in Polygonum cuspidatum samples by this method is efficient. The method developed in this work exhibits several significant merits, including easy operation and high extraction efficiency, indicating that electrochem. prepared polymer sorbent is useful for sample pretreatment and anal. of traditional Chinese medicine samples. 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. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Recommanded Product: 27208-80-6
