Nonnatural amino acid 3-(4-thiazolyl)-D,L-alanine hydrochloride and its four intermediates were synthesized, their structures were detenmined by IR,NMR,elementary analysis and melting point.
Different solvent extractions of Spora Lygodii were obtained using methanol,chloroform and petroleum ether as medium.Experiments were carried out on them by FT-IR spectra.
Abstract: Objective To evaluate the clinical efficacy of dimethyldiguanide and Gliclazide capsule in treatment of type 2 diabetic insulin resistance (IR) and fat metabolism disorder.
Through IR analysis, the main component in group II was identified as dialkyl-benzene, while in Group III was monoalkyl-benzene as well as dialkyl-tetralin and indane (DTI).
Using lead benzoxy as curing agent,cured epoxy resin was analyzed by means of IR spectrum and DSC curves.Lead benzoxy was considered to be catalytic curing agent.
