| 摘 要： | 目的:探讨四种棋楠沉香(Lignum Aquilariae Resinatum Qinan)黑棋、绿棋、黄棋、紫棋的红外鉴别特征和鉴定方法,为商品棋楠的质量评价提供科学依据。方法:采用傅里叶红外光谱法(FTIR)和二阶导数光谱法。结果:四种棋楠沉香的特征吸收峰为:2929、1735、1659、1512、1454、1377、1329、1267、1160、1055、897、700、561cm-1。其中,1244cm-1是黄棋特征峰;1650、1384、1246、1122、849、781、759cm-1是绿棋特征峰;1602、1103、10034、861、750cm-1是黑棋特征峰;1638、1601、1388、1272、1246、1122、1032、965、847、780、758cm-1是紫棋特征峰。在二阶导数谱中,1658、1512、1454、1377、1317、1163、1128、895、780、700cm-1处的吸收峰经二阶导后强度增强,在谱图上特征性更明显。经比较,绿棋和紫棋之间的相似度比较高。结论:红外光谱鉴定法简便易行,可用于棋楠沉香的定性鉴别。 |

| Abstract: | Objects: To study the identification method of Lignum Aquilariae Resinatum Qinan from four species (Yellow Qinan, Green Qinan, Black Qinan, and Violet Qinan) by Fourier transform infrared spectrum (FTIR),and supply the science data for identification of Lignum Aquilariae Resinatum Qinan. Methods: Determine the infrared spectrum and secondary derivative infrared spectrum by Fourier transform. Results: The characteristic peaks of four species are:2929, 1735, 1659, 1512, 1454, 1377, 1329, 1267, 1160, 1055, 897... |
