摘要

摘要研究了从蔓越莓(Vaccinium oxycoccus)中分离的结晶d -甘露糖(C6H12O6)电离辐射产生的稳定EPR信号。将辐照样品在95°C下等温加热10分钟(d -甘露糖的熔点为132°C)，导致EPR信号的修改和简化。在热处理样品的EPR信号中发现了各向同性四重奏。提出了在d -甘露糖晶体的复合EPR信号中发现的各向同性四重奏分子结构。

Study on irradiated D-mannose isolated from cranberry

Abstract The stable EPR signal produced by ionizing radiation in crystalline D-mannose (C6H12O6) and separated from cranberries (Vaccinium oxycoccus) was studied. The isothermal heating of irradiated sample at 95°C for 10 minutes (melting point of D-mannose is 132°C) resulted in the modification and simplification of the EPR signal involved. The isotropic quartet has been recognized in the EPR signal of heat-treated sample. Molecular structure of the isotropic quartet identified in the complex EPR signal of D-mannose crystallite is proposed.
