香料和草药不仅因为它们的味道、香气和味道而闻名，而且还因为它们的药用特性和价值而闻名。几个世纪以来，香料和草药在传统医疗系统中被用来治疗各种疾病，如普通感冒、糖尿病、咳嗽和癌症。本工作的目的是比较两种不同的提取工艺，以获得四种不同香料(肉桂、西红花、香茅、西红花)的生物活性成分的定性和定量数据。这些植物是用超声波和微波辅助提取的。微波萃取法提取活性物质的效率一般比超声萃取法高4倍左右。用ABTS、DPPH和FRAP分析了各种提取物的抗氧化活性，并测定了它们的总多酚含量。可以得出结论，微波辅助提取在提取效率和节省时间方面具有显著的优势。
Spices and herbs are known not only for their taste, aroma and flavour, but also for their medical properties and value. Both spices and herbs have been used for centuries in traditional medical systems to cure various kinds of illnesses such as common cold, diabetes, cough and cancers. The aim of this work was the comparison between two different extractive techniques in order to get qualitative and quantitative data regarding bioactive compounds of four different spices (Cinnamomum zeylanicum, Coriandrum sativum, Cuminum cyminum, Crocus sativus). The plants were extracted employing ultrasonication and microwave-assisted extractions. The efficiency of extraction of bioactive compounds obtained with the microwave extraction process was in general about four times higher than that resulting from sonication extraction. The various extracts obtained were analyzed for their antioxidant activity using ABTS, DPPH and FRAP assays and for their total polyphenolic content. It can be concluded that microwave-assisted extractions provide significant advantages in terms of extraction efficiency and time savings.
