Abstract

Abstract: The ¹³C CP MAS NMR spectra of silkworm cocoon from Henan Bombyx mori (B mori), Antheraea pernyi (A. pernyi), artificial white cocoon and their silk fibroins in solid state were first recorded on Bruker AC-250 and MSL-400 NMR spectrometer. The ¹³C NMR spectral lines were assigned and the difference in secondary structure of silk protein from A. pernyi yellow and white cocoon was revealed.

Key words: ¹³C CP MAS NMR spectra, Bombyx mori (B.mori), Fibroin, Silkworm cocoon, Antheraea pernyi (A.pernyi)
