Dragon's blood is the colloquial name for the red resin produced by tree species in the genus Dracaena (Asparagaceae), and the resin is directly involved in plant defensive mechanisms against pathogen and herbivore attack. It is also widely used in traditional folk medicine due to its antiviral, antimicrobial and antitumor activities. In the present work, a method using solid phase microextraction combined with two-dimensional gas chromatography with time-of-flight mass spectrometric detection was developed for the analysis of resin from five Dracaena species, namely Dracaena cinnabari Balf. f., D. serrulata Baker, D. ombet Heuglin ex Kotschy & Peyr., D. draco subsp. draco, and D. draco subsp. ajgal. Twenty terpenoid components in the resins of the five species were identified after comparative study of the volatile metabolite profiles. Monoterpenes were found to be species specific, and the observed differences might be further investigated as a possible means of identifying chemotaxonomic markers. In addition, for the first time, we describe the terpenoid volatile profiles of D. ombet and D. serrulata resins.

龙血树属树脂的萜类成分具有物种特异性
龙血是龙血树属（天门冬科）树种产生的红色树脂的俗称，该树脂直接参与植物抵御病原体和食草动物攻击的防御机制。由于其抗病毒、抗菌和抗肿瘤活性，它还广泛用于传统民间医学。在目前的工作中，开发了一种使用固相微萃取结合二维气相色谱和飞行时间质谱检测的方法，用于分析五种龙血树属植物，即龙血树属 cinnabari Balf 的树脂。f., D. serrulata Baker, D. ombet Heuglin ex Kotschy & Peyr., D. draco subsp. draco 和 D. draco subsp。艾加尔。在对挥发性代谢物谱进行比较研究后，确定了五种树脂中的 20 种萜类成分。单萜被发现具有物种特异性，观察到的差异可能会作为鉴定化学分类标记的一种可能手段进行进一步研究。此外，我们首次描述了 D. ombet 和 D. serrulata 树脂的萜类挥发性特征。
