Abstract

Ecological conditions of the growing areas, growing practices as well as harvest and postharvest processing influence the yield and quality of chamomile. The aim of this research was to determine the influence of chamomile separation methods, as postharvest treatments, on the essential oil quality and content, with a view to improve current primary processing of this valuable medicinal plant. In order to explain the structure of laboratory data that would give deeper assessment of similarities among various samples of chamomile essential oil, PCA was employed. Tested results showed that separation of chamomile plant material, as postharvest and pre-drying treatment, had significant influence on the number of identified compounds in the chamomile essential oil. The highest content of individual essential oil compounds had chamomile flowers with short stems, especially a-bisabolol, chamazulene, Z-spiroether and E-b-famesene. In the essential oil obtained from chamomile flowers with long stems, content of a-bisabolol and chamazulene were significantly lower, while E-b-famesene and Z-spiroether contents were significantly higher. Furthermore, in the essential oil obtained from chamomile plant material without separation, the lowest content of abisabolol and Z-spiroether, and the highest content of E-b-farnesene were recorded. The correlation analysis was performed to investigate the likeness in the amounts of the active compounds of essential oil from differently processed chamomile samples. All these results indicate the importance of precise and controlled postharvest treatments, since it clearly affects the essential oil quality and content in the primary processing of this valuable medicinal plant.

采后分离处理对洋甘菊精油品质的影响
种植区的生态条件、种植方式以及收获和采后加工影响洋甘菊的产量和品质。本研究的目的是确定洋甘菊分离方法作为采收后处理对其精油质量和含量的影响,以期改进目前这种珍贵药用植物的初级加工。为了解释实验室数据的结构,从而更深入地评估洋甘菊精油不同样品之间的相似性,采用主成分分析法。实验结果表明,分离洋甘菊植物材料,采后和预干燥处理对洋甘菊精油中鉴定化合物的数量有显著影响。其中,短茎洋甘菊挥发油中单体挥发油化合物含量最高,特别是a-双abolol、chamazulene、Z-spiroether和E-b-famesene。长茎洋甘菊精油中a-bisabolol和chamazulene含量较低,E-b-famesene和Z-spiroether含量较高。此外,未经分离的洋甘菊植物原料精油中,阿异abolol和z -螺醚含量最低,e -b-法尼烯含量最高。通过相关分析,探讨不同加工方法洋甘菊挥发油中活性成分含量的相似性。这些结果表明采后处理的精确和控制的重要性,因为采后处理明显影响到这种珍贵药用植物的初级加工中精油的质量和含量。
