Abstract: The determination of curcuminoids in mixtures is more difficult due to their similar chem. structures as well as serious interferences, thus the complex pretreatments of samples and the optimization of exptl. conditions are often required. Here, owing to the math. separation of chem. signals by Tchebichef image moments, a simple and effective approach to the simultaneous quant. anal. was proposed, and applied to the determination of the three curcuminoids in turmeric and curry based on their raw fluorescence 3D spectra. For the established linear models, the leave-one-out correlation coefficients (Rloo-cv) were more than 0.9816 within the linear ranges, and the predictive correlation coefficients (Rp) for the external independent samples were more than 0.9897. The intra- and inter-day precision (less than 6.82%, RSD), average spiked recovery (89.9% ∼ 100.8%), LOD (less than 0.07μg/mL) and LOQ (less than 0.23μg/mL) suggest that the proposed approach is accurate and reliable. Compared with N-PLS and MCR-ALS methods, our method can obtain more satisfactory results. This study provides a convenient pathway for the rapid anal. of multi-target components with similar chem. structures in mixture of different substrates. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Recommanded Product: 33171-05-0).
Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 33171-05-0
