摘要: 本文分别测定了东北天蚕茧和龙蛓天蚕茧各内,中,外三层茧层的固态13C CP-MASNMR波谱,对其谱峰进行了归属,估算了谱峰区主要谱线在该区所占的比例,还计算了各个茧层丝蛋白中无定形状态所占的百分含量。谱图显示了东北天蚕茧层与龙(蛓)天蚕茧层丝蛋白结构的差异。

Abstract: The 13C CP MAS NMR spectra of three cocoon shells (inside, middle and outside layer of the shell) of Dong Bei Antheraea yamamai (A. yamamai) and Rhodinia fugax were recorded and spectral lines were assigned. The ratioes of main Ine in the spectral area and amorphous region percentage were calculated. The spectra show that the structure of silk protein of Dong Bei Antheraea yamamai cocoon shell is different from that of Rhodinia fugax.

Key words: Antheraea yamamai cocoon shell, Rhodinia fugax, 13C CP MAS NMR spectra
