使用傅里叶红外光谱(FTIR)对南方红豆杉[(Taxus wallichiana var. mairei (Lemée & Léveillé.) L. K. Fu & Nan Li)]样本进行了检测和分析。结果表明,9个南方红豆杉样本的主要共有吸收峰一致,部分共有峰在不同样本中的峰相对强度有一定的差异。经对叶、树皮和木材不同部位红外光谱进行比较,叶在2850 cm-1处独有的C-H弯曲振动吸收峰、树皮在1741~1730 cm-1范围内无明显吸收峰,这些特征可作为部位间识别的光谱特征。叶和树皮波数在1620 cm-1位置的较强吸收峰强度、在1151~1146 cm-1范围内有明显的吸收峰,可以反映出紫杉醇在树皮和叶样本中的含量明显高于木材。此外,经过对3个产地南方红豆杉样本的比对,证明产地间样本的红外图谱具有一定的差异,主要体现在峰形、特征吸收峰的数量及强度等方面。

Fourier Transform Infrared Spectroscopy (FTIR) was adopted to investigate the Taxus chinensis. Results showed that nine samples had the same main common absorption peak, while other common peaks differed in relative intensive for various samples. Through the comparison of FTIR spectrum, characteristics such as C-H bending vibration absorption peak at wave number of 2 850 cm-1 for leaves, and none obvious absorption peak at range of 1 741~1 730 cm-1 for bark can be observed, which could be used as the spectral characteristics of recognition between different parts. It can be infered that the amount of taxol was high in bark and leaves than in wood, since the bark and leaves possess strong absorption peak at 1 620 cm-1 and obvious peak at the range of 1 151~1 146 cm-1. Besides, the comparison between T. chinensis origins from three different area indicated that FTIR spectrum differs for different samples mainly in peak shape, the numbers and intensive of characteristic absorption peaks.
