Method for detecting volatile terpenes in dendrobium officinale

The invention provides a method for detecting volatile terpenes in dendrobium officinale, and belongs to the technical field of detection of volatile terpenes. The method for detecting the volatile terpenes in the dendrobium officinale comprises the following steps that the dendrobium officinale is subjected to headspace extraction for 1 h by using a solid-phase microextraction device, an extraction head is removed and inserted into a vaporizing chamber of a gas chromatography sampling device to perform desorption, and then GC-MS analysis is carried out. According to the method for detecting the volatile terpenes in the dendrobium officinale, a Headspace SPME-GC-MS method is used for detecting the volatile terpenes of the dendrobium officinale, the initial qualitative and quantitative analysis of the volatile terpenes can be performed by a peak value and a peak area of a target object, and the operation is simple. 本发明提供了一种检测铁皮石斛中挥发性萜类的方法，属于挥发性萜类物质检测技术领域。本发明所述方法包括以下步骤：利用固相微萃取装置顶空萃取铁皮石斛1h后，取下萃取头插入气相色谱进样装置的气化室内完
