Regarding the antimicrobial activity, the ethanolic extract exhibited moderate antimicrobial activity with respect to bacteria K. pneumoniae and S. epidermidis, whereas, regarding other microorganisms, it showed activity considered weak. The aqueous extract and the essential oil showed activity considered weak, although they inhibited the growth of microorganisms. About the antioxidant potential, the ethanolic and aqueous extracts exhibited a scavenging index exceeding 90%, while the essential oil didn\u00b4t show significant antioxidant activity. Regarding the phytochemical composition, the largest class of volatile compounds identified in the essential oil of P. cattleianum included the following terpenic hydrocarbons: \u03b1-copaene (22%); eucalyptol (15%), \u03b4-cadinene (9.63%) and \u03b1-selinene (6.5%). The phytochemical screening of extracts showed the presence of tannins, flavonoids, and triterpenoids for aqueous and ethanolic extracts. The extracts and essential oils inhibit the growth of microrganisms and plant extracts showed significant antioxidant activity. Also, the phytochemical characterization of the essential oil showed the presence of compounds interest commercial, as well as extracts showed the presence of important classes and compounds with biological activities.<\/jats:p>","DOI":"10.1590\/1519-6984.13714","type":"journal-article","created":{"date-parts":[[2016,2,6]],"date-time":"2016-02-06T18:59:14Z","timestamp":1454785154000},"page":"101-108","source":"Crossref","is-referenced-by-count":60,"title":["Antimicrobial and antioxidant activity of essential oil and different plant extracts of Psidium cattleianum Sabine"],"prefix":"10.1590","volume":"76","author":[{"given":"M.
