运用FTIR技术,采集地枫皮及其伪品植物假地枫皮和大八角的根皮、茎皮和叶片等的红外光谱图,研究地枫皮与其伪品植物不同部位的红外光谱差异。结果显示,3种植物不同部位的红外光谱图均有较大差异,在1628cm~(-1)处地枫皮根皮有特征吸收峰;在1724、1710、1497、1484cm~(-1)等处地枫皮茎皮有明显特征吸收峰;地枫皮叶片3401cm~(-1)和614cm~(-1)两处的吸收峰,在假地枫皮和大八角中分别飘逸到3376,3345cm~(-1)和1627,1625cm~(-1)附近;地枫皮不同部位主要化学成分构成比较相似,但是同类化学成分的含量存在较大差异。所以运用FTIR技术可以快速鉴别出地枫皮与其伪品假地枫皮和大八角,并可以判断3种植物主要化学成分的差异。
FTIR techniques were used to study the infrared spectra of the roots, stem barks and leaves of Maple Habitat and its counterfeit plants. The results showed that there were significant differences in the infrared spectra of different parts of the three plants, with the characteristic absorption peak at 1628cm -1, and at 1724,1710,1497,1484cm -1 The maple bark had obvious characteristic absorption peaks. The absorption peaks at 3401cm -1 and 614cm -1 of Maple Leaf were floating to 3376 and 3345cm ~ (-1) and 1627, 1625cm ~ (-1), respectively. The main chemical components of different parts of F. mongolica were similar, but the contents of the same chemical components were quite different. Therefore, using FTIR technology can quickly identify to maple and its counterfeit maple Peach and Big Octagonal, and can determine the difference in the three main chemical composition of plants.
