Abstract

Limited essential oil (EO) investigation has been conducted on the genus Ageratum. In particular, the annual herb Ageratum conyzoides L., which grows throughout equatorial regions of South America, Asia, and West Africa, is well-known for its many chemical components as well as its traditional medicinal applications. The EO yields form two extraction methods one is conventional and the other is modern method which is referred to as a green method. Both extraction techniques were successful in obtaining phytochemicals from this species, as evidenced by the discovery of 79 and 42 components in the two methods by GC/MS analysis. Results highlight Ageratum conyzoides L. conventional medicine's use and its EO potentiality as a source of bioactive compounds.
Hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD) were the two primary techniques used to extract the EO of Egyptian Ageratum conyzoides L. aerial parts. GC/MS were used for the investigation, so as to compare the outcomes of the HD and MAHD methods, the chemical composition of the EO was assessed.
