Propolis has been used worldwide for years in folk medicine and currently marketed by the pharmaceutical industry. In Brazil, propolis was classified into 13 groups based on their organoleptics physicochemical characteristics. The 13th type named red an important source of investigation since late 90s. Their property comes from countless compounds, including terpenes, pterocarpans, prenylated benzophenones especially flavonoids. This last compound class indicated as responsible its potent...
The genus Mikania ranks high in the list of best-selling natural products world. Its main distribution is South America, but some species are found Asia, North America and Africa. It used for treating fever, rheumatism, colds respiratory diseases, as well snake bites scorpion stings, due to its broad spectrum action. There approximately 430 this only 12% have been studied, highlighting their chemical pharmacological diversity. groups are: coumarins derivatives, sesquiterpenes, sesquiterpenes...
Most studies of Brazilian red propolis have explored the composition and biological properties its ethanolic extracts. In this work, we chemically extracted characterized essential oil (EOP) assessed adjuvant, antiparasitic cytotoxic activities. The chemical EOP was analyzed using gas chromatography with mass spectrometry (GC-MS). tested for in vitro activity against Trichomonas vaginalis (ATCC 30236 isolate); trophozoites were treated different concentrations (ranging from 25 to 500 μg/mL)...
Cancer is the second major cause of mortality worldwide, losing only to cardiovascular disease. Nowadays, around 50% antineoplastic drugs were discovered and isolated by indications plants in folk medicine. In Brazilian flora there are many species which have great therapeutic importance, highlighting Mikania laevigata (Asteraceae) that has been used for their valuable properties, especially respiratory tract. present study, compounds M. extracts characterized High Resolution Mass...
In Brazil there are nine native species of Aloysia which poorly studied as the chemical compositions and biological activities. Hence, this study describes composition determinated by GC-MS essential oil five one cultivated occurring in Rio Grande do Sul evaluates cytotoxic effects oils from A. citrodora, lycioides dusenii through bioassay with Artemia salina. A group showed 1,8-cineol a major compound: (16.2 %), citrodora (32.8 collected Guaiba (49.5 %) São Marcos (17.6 %). While...
