| "The essential oils isolated from the leaves of [[http://en.wikipedia.org/wiki/Ageratum_houstonianum|Ageratum houstonianum]] Mill, and Ageratum conyzoides L. by hydrodistillation were analysed by GLC and GC-MS. The essential oil of A. houstonianum contained 7-methoxy-2,2-dimethylchromene (precocene I) and ageratochromene (precocene II) in almost similar amounts (32% and 24% respectively) whereas that of A. conyzoides was rich in precocene I (81%) and poor in precocene II (0.2%)." \\ | "The essential oils isolated from the leaves of [[http://en.wikipedia.org/wiki/Ageratum_houstonianum|Ageratum houstonianum]] Mill, and Ageratum conyzoides L. by hydrodistillation were analysed by GLC and GC-MS.

| "Aqueous extracts of Ageratum conyzoides L. harvested in Brazil (commercial, flowering and non-flowering samples) were prepared according to the prescribed method and analyzed by HPLC-HRMS. The pyrrolizidine alkaloids lycopsamine, dihydrolycopsamine, and acetyl-lycopsamine and their N-oxides, were detected in the analyzed extracts, lycopsamine and its N-oxide being known hepatotoxins and tumorigens." \\ | "Aqueous extracts of Ageratum conyzoides L. harvested in Brazil (commercial, flowering and non-flowering samples) were prepared according to the prescribed method and analyzed by HPLC-HRMS. The pyrrolizidine alkaloids lycopsamine, dihydrolycopsamine, and acetyl-lycopsamine and their N-oxides, were detected in the analyzed extracts, lycopsamine and its N-oxide being known hepatotoxins and tumorigens. Together with the pyrrolizidine alkaloids identified by HPLC-HRMS, thirteen phenolic compounds were identified, notably, methoxylated flavonoids and chromenes. Toxicological studies on A. conyzoides are necessary, as is monitoring of its clinical use. To date, there are no established safety guidelines on pyrrolizidine alkaloids-containing plants, and their use in Brazil." \\ |
