A simple microwave distillation was used in order to prevent the traditional prolonged hydrodistillation. To this end, the volatile compounds in aerial sections of DC were analyzed. Then, headspace single drop micro-extraction (HS-SDME) was done that was connected to gas chromatography-mass spectrometry (GC-MS). Following irradiation, the volatile components of headspace were gathered through an n-heptadecane single drop. The relative peak areas, which were used as the index, optimized the conditions of extraction. The indexes of retention and mass spectra were used for confirmation of chemical configuration in the extracts of HS-SDME.
为避免传统的长时间水蒸馏，采用了一种简单的微波蒸馏。为此，对 DC 空中部分的挥发性化合物进行了分析。然后，进行了顶空单滴微萃取（HS-SDME），并与气相色谱-质谱联用（GC-MS）连接。辐射后，通过正十七烷单滴收集顶空的挥发性成分。相对峰面积用作提取条件优化的指标。保留指数和质谱用于确认 HS-SDME 提取物中的化学结构。
