N-2-hydroxyethyl glucamine and 6-(N-hydroxyethyl)-amino-6-deoxy-alpha-L-sorbofuranose, has long been a challenge. In this study, derivatization reagents were screened, and then a novel HPLC method coupled with 9-fluorenylmethyl chloroformate derivatization was developed for the quantitative...
This enzyme seems not only to prefer UDP-glucose and HPP2 as a favorable glycosyl donor and acceptor, respectively but also differentiates the positional difference of the hydroxyl function as acceptor catalytic sites. Paired in vitro and in vivo antioxidant assays represented SPs and their ...
In the case of both dyes, two systems that differ in the ratio of the amount of dye to the mass of CCP sample were prepared (Table 1). The CCP sample was added to the dye stock solution while stirring. Table 1. Composition of the mixtures of organic dye (rhodamine B or phloxine B...
