芫荽的挥发性成分，Satureja montana L.，山茱萸，和红蓟（Thalumvulgaris L.）通过水蒸馏（精油）和超临界流体萃取（挥发油）分离。研究了它们对四种作物（Zea mays L.，硬粒小麦，豌豆，和莴苣）和2种杂草（马齿苋PortulacaoleraceaL.）和Vicia sativa L.）并与合成除草剂Agrocide和Prowl进行了比较。百里香和棉熏衣草的挥发油似乎是合成除草剂的有希望的替代品，因为它们对作物物种的伤害最小。另一方面，冬香精油对作物和杂草都有影响，适用于未开垦的农田。
The volatiles from Coriandrum sativum L., Satureja montana L., Santolina chamaecyparissus L., and Thymus vulgaris L. were isolated by hydrodistillation (essential oil) and supercritical fluid extraction (volatile oil). Their effect on seed germination and root and shoot growth of the surviving seedlings of four crops (Zea mays L., Triticum durum L., Pisum sativum L., and Lactuca sativa L.) and two weeds (Portulaca oleracea L. and Vicia sativa L.) was investigated and compared with those of two synthetic herbicides, Agrocide and Prowl. The volatile oils of thyme and cotton lavender seemed to be promising alternatives to the synthetic herbicides because they were the least injurious to the crop species. The essential oil of winter savory, on the other hand, affected both crop and weeds and can be appropriate for uncultivated fields.
