云南昭通天麻品种多样、珍贵，有研究价值，因此本文选取了昭通紫天麻和乌天麻作为研究材料，以天麻中的有效成分为研究指标，用95%的乙醇溶液和无水乙醇溶液溶解两种天麻样品，利用超声波提取仪提取紫天麻和乌天麻中的有效成分，然后，在波长200—800nm范围内通过紫外—可见分光光度计对两种天麻样品提取液进行紫外图谱扫描，对两种天麻中的有效成分进行初步定性分析，为红外光谱分析提供数据支持。
结果表明：在波长200—400nm范围内有较强的吸收，通过紫外光谱、红外光谱测定和查阅资料，表明昭通紫天麻和乌天麻都含有天麻素、香荚兰醇、对羟基苯甲醇、天麻多糖等多种有效成分，而且两种天麻在化学组成上有明显的相似性，但在具体有效成分及含量上仍有差异。因此，本文可为紫天麻和乌天麻的红外光谱测定提供依据。

Yunnan Zhaotong Tianma variety, precious, research value, therefore this paper selects the Zhaotong purple and Gastrodia Gastrodia elata Blume as research material, the effective components of Gastrodia elata on the index, with 95% ethanol solution and ethanol solution of two kinds of Gastrodia elata, using ultrasonic wave extraction to extract the effective components of Gastrodia elata, purple and black in Gastrodia elata and then, at the wavelength of 200 800nm range by UV - Visible Spectrophotometer in two kinds of Gastrodia elata extract by UV spectrum scanning, a preliminary qualitative analysis of the two effective components of Gastrodia elata, provide data support for the infrared spectral analysis. The results show that:At the wavelength of 200 400nm in the range of strong absorption, UV spectra, IR spectra and access to information, show Zhaotong Gastrodia Gastrodia purple and contained gastrodin, vanillyl alcohol, on the effective components of Gastrodia elata polysaccharide hydroxyl benzyl alcohol, etc., and two kinds of Gastrodia elata in chemical composition is similar obviously, but there are still differences in the content of the available composition. Therefore, this paper provides the basis for the determination of infrared spectroscopy for the purple and Gastrodia Gastrodia elata.
