The present invention starts with a method for obtaining organic extracts of the Artemisia absinthium L. plant, which includes: a methodology phase for producing said plant, an extraction phase during which said essential oil and a non-volatile extract are obtained, and a phase of extracting supercritical extracts with CO2, and refers specifically to the use of the essential oil and/or the supercritical extract extracted as fungicides against phytopathogenic fungi. For said purpose, the Artemisia absinthium L. plant is used, specifically the Candial variety from Teruel and/or Sierra Nevada in Spain. The present invention also relates to the aqueous residue generated during said method, which includes an organic compound which in turn contains (Z)-2,6-dimethylocta-5,7-diene-2,3-diol as an active organic compound against nematodes. The method for obtaining said organic portion and the corresponding active organic component thereof is protected by the present application.
本发明首先提出了一种获得苦艾蒿有机萃取物的方法,该方法包括:生产苦艾蒿的方法阶段,获得精油和非挥发性萃取物的萃取阶段,以及用二氧化碳萃取超临界萃取物的阶段,具体是指将萃取的精油和/或超临界萃取物用作杀真菌剂,以对抗植物病原真菌。为此,本发明使用了苦艾蒿(Artemisia absinthium L.)植物,特别是来自西班牙特鲁埃尔(Teruel)和/或内华达山脉(Sierra Nevada)的坎迪亚尔(Candial)品种。本发明还涉及在上述方法中产生的水性残留物,其中包括一种有机化合物,该有机化合物又含有 (Z)-2,6-dimethylocta-5,7-diene-2,3-diol 作为抗线虫的活性有机化合物。获得所述有机部分及其相应活性有机成分的方法受本申请保护。
