EI-MS分析法为天麻GastrodiaelataBlume真伪鉴别的一种新方法。因为从天麻干燥根甲醇提取液获得的EI-MS质谱图具有指纹性特征,故可做为鉴别天麻真伪的依据。此方法不失为一种快速、简单、灵敏、有效的品种鉴定手段。
The EI-MS analysis method is a new method for authenticating gastrodia Gastrodiaelata Blume. Because the EI-MS mass spectrum obtained from the dried root extract of Gastrodia elata has fingerprint characteristics, it can be used as a basis for authenticating the authenticity of Gastrodia elata. This method is a quick, simple, sensitive, and effective method for species identification.
