Site-specific glycoprofiling of N-glycoproteins is based on the enrichment of glycopeptides. In this study, we develop a simple and economical ZipTip microcolumn packed with a 1:1 ratio of graphite carbon to activated charcoal (w/w) (termed as GA-ZipTip microcolumn) to efficiently isolate and enrich N-glycopeptides from digested mixtures of individual… (More)
Novel chitosan/ZnO nanoparticle (CS/nano-ZnO) composite membranes were prepared via the method of sol-cast transformation and studied by UV-vis absorption spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray fluorescence spectrometry (EDX). The… (More)
Five minor alkaloids were isolated from the stems of NAUCLEA OFFICINALIS Pierre ex Pitard: three new alkaloids named naucleficine ( 1), nauclefidine ( 2) and nauclefoline ( 3), and two known alkaloids 1-acetyl-beta-carboline and naucleidinal, along with vanillic acid.
