The yield, chemical components and relative contents of essential oil extracted from Eupatorium adenophorum Spreng by Soxhlet extraction and steam distillation were compared. The volatile chemical constituents of essential soil extracted were analyzed by Gas Chromatography-Mass Spetrometry. The results showed that the constituents of the volatile from the same plant and the relative contents were significantly different due to different extraction methods.

采用索氏提取器及水蒸气蒸馏两种方法对采于不同时间、不同产地的紫茎泽兰Eupatorium adenophorum Spreng挥发性成分进行了提取，比较了两种方法的得油率、化学组成及其相对含量；采用GC-MS联用技术对其中的挥发性成分进行了分析。

Firstly, headspace solid-phase microextraction was established to determine AITC by orthogonal design. Extraction temperature, stir speed, extraction time, and desorption time were set at 40℃, 900r/min, 30min, and 5min, respectively. Under these optimal conditions, volatile flavor compounds in mustard oil, wasabi, and 'Chongcai'leaf mustard product were identified by SPME/GC/MS. In these three samples, 6,12,17 constituents were identified respectively; Allyl isothiocyanate was the main flavor compound, which accounted for 73.45%, 64.25%, 32.74% of total volatile compounds, respectively. Carbon disulfide, a hydrolysis product of AITC, accounted for 14.37% 25.40%, 51.67% of total volatile compounds respectively. There were some other isothiocycannates, such as butane, 1-isothiocyanato-, isobutyl isothiocyanate, 1-benzene, 4-isothiocyanato-, benzene (2-isothiocyanatoethyl)-, etc.

首先采用正交实验设计优化固相微萃取技术的前处理条件，结果表明，以萃取温度40℃、搅拌速度900r／min、萃取时间30min、解吸时间5min为最佳条件；在此最优条件基础上，利用SPME／GC／MS联用技术分析芥末油、青芥辣、冲菜的挥发性风味成分，分别检出6、12、17种化合物，主要风味物质均为AITC，相对丰度分别为73.45％、64.25％、32.74％；AITC的水解产物二硫化碳的相对丰度分别为14.37％、25.40％、51.67％；还检测到了其它几种异硫氰酸酯，如异硫氰酸丁酯、异硫氰酸异丁酯、异硫氰酸丁烯酯、2-苯乙基异硫氰酸酯等。
