Turmeric products have many useful physiol. functions and are widely used as health food and food ingredient. Here, we report the use of HPLC-ESI-MS/MS to simultaneously quantify bisacurone and three curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) in turmeric products (high viscosity liquid, granular powder, tablet, and solution). The results showed that the standard values and measured values of curcumin in each product were almost same. Demethoxycurcumin and bisdeme-thoxycurcumin were contained in each products. Meanwhile, the content of bisacurone differed greatly among the products. In particular, the highest amount of bisacurone was found in the turmeric product A (high viscosity liquid, 9.48 g/100 g product). It would become important to consider the bisacurone content in turmeric products. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0HPLC of Formula: 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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 33171-05-0
