Cold-pressed plant oils are of high interest to consumers due to their unique and interesting flavors. As they are usually only pressed at low temperatures and filtered, without further processing stages (as refining), they preserve their character that originates from the plant the oil was extracted from. Coriander cold pressed oil is gaining popularity as a novel product, obtained from its fruits/seeds; due to the high amount of terpenes, it has very characteristic flavor. A novel, vacuum-assisted sorbent extraction (VASE) method was used to extract terpenes from coriander cold pressed oil. Optimal parameters were determined. The profile of compounds extracted using VASE was compared with that of classic hydrodistillation method. Moreover, 17 monoterpene hydrocarbons and alcohols were identified with β-linalool as the main compound, followed by α-pinene, γ-terpinene, camphor, sylvestrene, β-pinene, and o-cymene. Differences were noted between profiles of terpenes after hydrodistillation and VASE extraction. For 8 out of 17 terpenes, VASE was used for their quantitative analysis. Regarding simplicity of the method, small sample requirement (200 mg) and short extraction time (5 min), VASE combined with GC/MS is well suited for characterization of terpenes in such matrix as plant oils.
冷榨植物油因其独特而有趣的风味而受到消费者的高度关注。由于它们通常只在低温下压榨并经过过滤，而没有进一步的加工阶段（如精炼），因此保留了它们源自提取油的植物的特性。芫荽冷榨油作为一种新产品越来越受欢迎，它是从其果实/种子中获得的；由于萜烯含量很高，它具有非常独特的风味。本文采用一种新颖的真空辅助吸附萃取（VASE）方法从芫荽冷榨油中提取萜烯。确定了最佳参数。使用 VASE 提取的化合物的图谱与经典的水蒸馏法进行了比较。此外，鉴定了 17 种单萜烃和醇类化合物，其中主要化合物为β-芳樟醇，其次为α-蒎烯、γ-松油烯、樟脑、冷杉烯、β-蒎烯和对伞花烃。水蒸馏和 VASE 萃取后的萜烯图谱存在差异。对于 17 种萜烯中的 8 种，VASE 用于其定量分析。考虑到方法的简单性、小样品需求（200mg）和短提取时间（5 分钟），VASE 结合 GC/MS 非常适合于植物油等基质中萜烯的特征化。
