“…[6][7][8] To verify if this result it would have been caused by a seasonal condition, the essential oils were collected and analyzed monthly during the years 2002 and 2003. To minimize the effects of the variation of other such factors as soil composition, humidity, light intensity, and others, the leaves, flower and fruits were always collected from two specimens very close each other.…”

“…4,5 The studies of essential oils of sixteen Myrcia species demonstrated that sesquiterpenes are predominant for all of them but for M. acuminatissima and M. bombycina for which the monoterpenes fraction is slightly larger. [6][7][8] In a study with volatile oils of some Myrtaceae species the lack of activity against Escherichia coli and good activity against Staphylococcus aureus and S. epidermidis in the majority of species was related. 9 The antifungal activity of essential oils from Myrtaceae species against dermatophytes was attributed to its terpenes constituents.…”

Os óleos essenciais das folhas, flores e frutos de Myrcia myrtifolia DC foram coletados ao longo dos anos de 2002 e 2003 e foram analisados utilizando CG-DIC e CG-EM. No total foram identificados 28 componentes sendo que o α-pineno foi a substância predominante em todas as amostras analisadas apresentando-se em concentrações que variaram entre 61.5 e 90.9%. As propriedades antimicrobianas do óleo essencial das folhas coletadas em outubro de 2002 foram avaliadas contra seis bactérias, duas leveduras e cinco fungos filamentosos sendo mais fortemente ativo contra Microsporum canis e Trichophyton rubrum, ativo contra Staphylococcus aureus, Staphylococcus aureus resistente à meticilina, Candida albicans, Cryptococcus neoformans e Aspergillus fumigatus. O óleo ainda mostrou uma toxicidade moderada, LC 50 of 479,16 μg mL -1 , contra Artemia salina.This work reports the seasonal variation of the composition of leaf volatile oils and the composition of volatile oils from flowers and fruits of Myrcia myrtifolia DC harvested in the sand dunes of Salvador, Bahia, northeastern region of Brazil between 2002 and 2003. The oils were analyzed by GC-FID and GC-MS so that 28 components were identified. α-Pinene was predominant in a range from 61.5 to 90.9% in all samples analyzed. The leaf oil collected in October 2002 had their antimicrobial properties tested against six bacteria, two yeasts and five filamentous fungi being active against Staphylococcus aureus, methicilin-resistant Staphylococcus aureus, Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus, and showed strongest activity against Microsporum canis and Trichophyton rubrum. The oil displayed moderate toxicity against Artemia salina showing a LC 50 of 479.16 μg mL -1 .Keywords: Myrtaceae, Myrcia myrtifolia, essential oil, monoterpene, sesquiterpene, antimicrobial activity IntroductionAromatic plants have been used since ancient times as antiseptics and anti-infectious agents, as aroma in perfumes and cosmetics as well as preservative and flavour ingredients in food and beverages. Their biological properties are directly related with their chemical compositions, which can be affected by environmental, geographical, seasonal and circadian variations.The family Myrtaceae is constituted by 140 genera with about 3000 species, which are widely distributed in America and Australia. 1 The genus Myrcia comprises more than 300 species that grow in all Brazilian territory. Indigenous tribes and traditional Brazilian communities have used several species of this genus as astringent, against diabetes and diarrhea, as diuretic, to stanch hemorrhages, against the hypertension and ulcers of the mouth. 2 Some works were published regarding the chemistry and the biological properties of Myrcia species. From M. citriofolia, the occurrence of a C-methylated flavone, eucalyptin, was related, 3 from the methanolic extract of M. multiflora were isolated flavonol, flavanone and acetophenone glucosides along with myricitrin, mearnssitin, quercitrin, desmanthin-1 and guaijaverin...

-Background -Given the increase of people with gastrointestinal disorders, the search for alternative treatments with fewer side effects is vital, as well as the demand for food or plants that can help protect the stomach. Objective -The aim of this study was to evaluate the gastroprotective action of the extracts of wild fruit trees of Myrcianthes pungens (guabiju); Inga vera Willd. (ingá-banana) and Marlierea tomentosa Cambess. (guarapuruna) in in vivo pharmacological models. Methods -The different parts of the fruits were separately subjected to a process of extraction by methanol. Two experimental pharmacological models were conducted in mice; the gastric ulcer model induced by non-steroidal anti-inflammatory (indomethacin), and the gastric ulcer model induced by ethanol/HCl, which allowed us to evaluate the gastroprotective activity of the extracts at a dose of 250 mg/kg. Subsequently, the total lesion area (mm 2 ) and relative lesion area (%) were determined. Results -The results showed significant gastroprotective activity against the aggressive agents used -ethanol and indomethacin -for all the extracts tested. Conclusion -It is assumed that the fruits have bioactive compounds such as antioxidant substances that act on the prostaglandin levels, protecting them from the damage caused by ethanol and indomethacin. These results prompt further studies to isolate and identify the active properties.

“…Dentre esses sesquiterpenos, pode-se destacar o β-cariofileno (Figura 1a), que é um dos compostos majoritários da oleorresina de algumas espécies Copaifera e também de óleos essenciais de diversos gêneros de plantas provenientes de diferentes regiões (Siani et al, 1999;Ramos et al, 2000;Limberger et al, 2004;Sousa et al, 2006). Várias atividades biológicas foram atribuídas a este sesquiterpeno, tais como: antiedematogênica, fagorrepelente, antiinflamatória, antitumoral, bactericida, insetífuga, espasmolítica e protetora contra danos no DNA (Shimizu, 1990;Jacobson et al, 1990;Keeler et al, 1991;Zheng et al, 1992;Kang et al, 1992;Duke, 1992;Veiga Junior et al, 2007;Di Sotto et al, 2010).…”
