“…In two antioxidant screening studies [6,11], the plant was found to display moderate radical scavenging effect against DPPH, which is in accordance with our findings. In Ibrahim et al's study [25], the leaf MeOH extract of C. sempervirens of Egyptian origin was revealed to have strong DPPH radical scavenging activity and several phenolic compounds including cosmosiin, caffeic acid, and p-coumaric acid, cupressuflavone, amentoflavone, rutin, quercitrin, quercetin, myricitrin were isolated from this extract.…”

“…Cupressus L. species (Cupressaceae), known as "cypress", are native to the Mediterranean basin and its leaves and cones have been used as folk remedy in many countries such as antiseptic, antipyretic, anthelminthic, astringent, antirheumatic, antihemorrhoidal, antidiarrhoeic, and vasoconstrictive [4][5][6]. The genus is also used for ornamental purpose and known to contain appreciable amounts of essential oil [7][8][9][10], which possess mainly antimicrobial [10,11], antiviral [12], and antifungal [13] activity. Besides, C. sempervirens was recorded to be used for memory-enhancement in Anatolia, which was described in a very old book written by an Ottoman herbalist-physician at the period of the ruler Sultan Mehmed the fourth (1641-1693) [14].…”

“…Some assays are based on the screening antioxidant activity of hydrophilic compounds and the others are able to determine antioxidant activity of hydrophobic compounds. In addition, the chemical complexity of essential oils, often a mixture of dozens of compounds with different functional groups, polarity and chemical behaviour, could lead to scattered results, depending on the test employed (Saccheti et al 2005). For this reason, antioxidant activity of essential oils was evaluated by using ABTS radical scavenging, DPPH radical scavenging and linoleic acid peroxidation assays.…”

“…There has been growing interest in the use of naturally occurring substances as antioxidants and antimicrobials in recent years (Pillai and Ramaswamy 2011). R. officinalis L. has been shown to exhibit antimicrobial and antioxidant activities (Baratta et al 1998;Pintore et al 2002;Angioni et al 2004;Saccheti et al 2005;Okoh et al 2010;Karpiǹska-Tymoszezyk 2011).…”

Effects of microwave assisted hydrodistillation (MAHD) and conventional hydrodistillation (HD) methods on yield, composition, specific gravity, refractive index, and antioxidant and antimicrobial activities of essential oil of Rosmarinus officinalis L were studied. The main aroma compounds of rosemary essential oil were found as 1,8-cineole and camphor. Trolox equivalent antioxidant capacity (TEAC) values for essential oils extracted by MAHD and HD were 1.52 mM/ml oil and 1.95 mM/ml oil, respectively. DPPH radical scavenging activity of the oils obtained by MAHD and HD were found as 60.55% and 51.04% respectively. Inhibitory effects of essential oils obtained by two methods on linoleic acid peroxidation were almost the same. Essential oils obtained by two methods inhibited growth of Esherichia coli O157:H7, Salmonella typhimurium NRRLE 4463 and Listeria monocytogenes Scott A with the same degree. However, inhibitory activity of essential oil obtained by MAHD on Staphylococcus aureus 6538P was stronger than that of obtained by HD (p<0.05).

“…In addition to the antimicrobial potential, the fact that some synthetic antioxidants widely used in the food industry can lead to the development of tumor cells has led to increase the demand for similar products of natural origin, among which essential oils and plant extracts that have phenolic compounds in their composition stand out for their important antioxidant activity (Sacchetti et al, 2005).…”

View full text Add to dashboard Cite

The goals of the study were to determine: the antimicrobial and antioxidant activities of essential oil and plant extracts aqueous and ethanolic of Psidium cattleianum Sabine; the chemical composition of the essential oil of P. cattleianum; and the phytochemical screening of aqueous and ethanolic extracts of the same plant. 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´t 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: α-copaene (22%); eucalyptol (15%), δ-cadinene (9.63%) and α-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.Keywords: Psidium cattleianum, antimicrobial action, microdilution, GC-MS, antioxidant activity. Atividade antimicrobiana e antioxidante do óleo essencial e diferentes extratos vegetais de Psidium cattleianum Sabine ResumoOs objetivos do trabalho foram determinar: as atividades antimicrobiana e antioxidante do óleo essencial e dos extratos vegetais aquoso e etanólico de Psidium cattleianum Sabine; a composição química do óleo essencial P. cattleianum e a triagem fitoquímica dos extratos vegetais aquoso e etanólico da mesma planta. Quanto à atividade antimicrobiana, o extrato etanólico apresentou atividade antimicrobiana moderada frente as bactérias K. pneumonieae e S. epidermidis, enquanto frente aos demais micro-organismos apresentou atividade considerada fraca. O extrato aquoso e o óleo essencial apresentaram atividade considerada fraca, embora tenham inibido o crescimento dos micro-organismos. Em relação ao potencial antioxidante, os extratos etanólico e aquoso apresentaram índice de sequestro superior a 90%, enquanto o óleo essencial não apresentou atividade antioxidante significativa. Para a composição fitoquímica, a maior classe de compostos voláteis identificados no óleo essencial de P. cattleianum foram os hidrocarbonetos terpênicos, sendo eles: α-copaeno (22%), eucaliptol (15%), δ-cadineno (9,63%) e α-selineno (6,5%). Na triagem fitoquímica dos extratos verificou-se a presença de taninos, flavonóides e triterpenói...
