摘要
目的:确定芝麻素单晶的结构。方法:分析X-射线单晶衍射(XRD)所测数据;对芝麻素的红外光谱(IR)、紫外光谱(UV)、质谱(MS)、核磁共振谱(NMR,含1H-NMR、13C-NMR)进行解析,对所有NMR信号进行归属,同时讨论MS主要碎片离子的分子离子峰数据和IR特征峰所对应的官能团的振动形式。结果:XRD分析结果显示样品空间结构与芝麻素单晶结构一致;IR、UV、MS、NMR分析所得样品图谱与芝麻素对照品图谱一致。结论:本试验所得谱图和数据可为芝麻素及其同类化合物的解析提供依据。
To identify the structure of sesamin single crystal. METHODS：To analyse the data obtained from X-ray diffraction （XRD） of single crystal. The structure of sesamin single crystal was analyzed by means of IR spectrum, UV spectrum, MS, ＇H-NMR and 13C-NMR. All the NMR signals were assigned. Based on the mass spectral data, the data of the main molecular ion was discussed. IR spectrum was analyzed to derive the types of vibration of the functional groups of this compound. RESULTS： The structure of sample was same to sesamin single crystal; IR, UV, MS and NMR spectrum were same to the spectrum of sesamin control. CONCLUSION ： Spetrum and data of the trial can provide reference for the analysis of sesamin and similar com- l^ounds.
