Abstract:
Alternanthera brasiliana is popularly known as 'penicillin' and used as an anti-inflammatory and for wound healing. The objective of this work was the phytochemical study of the species by analytical techniques such as LC-MS/MS and GC-MS. Twenty-seven compounds were identified, five by LC-MS and 22 by GC-MS analysis. All compounds identified by LC-MS are flavonoids. However, several classes were found in GC-MS analysis, such as hydrocarbons, diterpenes, monoterpenes, vitamin and carotenoid derivatives, phytosterols and triterpenes. In the analysis, it is suggested the presence of 27 substances, of which 23 are unpublished for the species, that reaffirms the importance of this study and the contribution to chemical knowledge.
