“…According to MANRIQUE;SANTANA (2008), propolis produced by the species T. angustula, also known as Jataí propolis, has a low concentration of flavonoids. A study by TAVARES et al (2010) has demonstrated that green propolis has flavonoids, whereas according to NUNES et al (2009) red propolis is composed of several phenolic compounds, flavonoids, anthraquinones and phenols. VYNOGRAD et al (2000) showed that the antiviral activity of propolis against genital herpesvirus (HSV) was attributed to flavonoids.…”

This study evaluated the in vitro antiviral activity of propolis and Baccharis sp. extracts on three animal herpesviruses (bovine, equine and swine). The propolis samples were produced by two species of bees. There was red and green propolis, which came from africanized Apis melifera, and a third type obtained from a native bee species, Tetragonisca angustula (jatai). The Baccharis extracts were obtained from four different species: B. oblongifolia, B. burchellii, B. dracunculifolia and B. uncinella. The maximum non-toxic concentration of the extracts was determined when no visible morphological changes were observed on the cells. These non-toxic concentrations were used in the antiviral tests. Antiviral activity was evaluated using a reduction assay of the cytopathic effect, which calculated the difference between treated and control virus titer by statistical analysis. Red propolis was active against the three herpesviruses and green propolis showed inhibition against the equine and swine herpesviruses. Conversely, jataí propolis showed no antiviral activity. Most extracts coming from male and female individuals of all of the Baccharis species showed antiviral activity against bovine and swine herpesviruses. Only the extract of the female specimen of B. oblongifolia was an inhibitor against equine herpesvirus.

Propolis is a resinous substance collected and processed by Apis mellifera from parts of plants, buds and exudates. In Minas Gerais (MG) state, Brazil, green propolis is produced from the collection of resinous substance found in shoot apices of Baccharis dracunculifolia. This paper aims to investigate the chemical composition and in vitro antioxidant, anti-Helicobacter pylori, antimycobacterial and antiproliferative activities of essential oil (EO) from Brazilian green propolis (BGP-EO). The oil showed high antibacterial activity against H. pylori (MIC = 6.25 µg/mL), Mycobacterium avium (MIC = 62.5 µg/mL) and M. tuberculosis (MIC = 64 µg/mL). Its antioxidant activity was evaluated in vitro by both DPPH (IC50 = 23.48 µg/mL) and ABTS (IC50 = 32.18 µg/mL) methods. The antiproliferative activity in normal (GM07492A, lung fibroblasts) HIGHLIGHTS The chemical composition of propolis varies according to the region where it is produced. Production of green propolis in Minas Gerais state, Brazil, is related to the high amount of resin yielded by Baccharis dracunculifolia. Major compounds found in essential oil from Brazilian green propolis were carvacrol, acetophenone, spathulenol, (E)-nerolidol and β-caryophyllene. Brazilian green propolis showed high antibacterial, antioxidant and antiproliferative activities.

The production of propolis by honeybees results from a selective collection of exudates from various plant species and present many potentialities in the pharmaceutical industry. The objective of this study was to investigate the chemical profile of Brazilian propolis, as well as their in vitro antioxidant and antibacterial activities. Gas chromatography-mass spectrometry was applied for chemical profiling of propolis extracts. Total phenolic compounds were quantified by Folin-Ciocalteu and antioxidant properties were assessed by 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay. Antibacterial activity was assessed against Staphylococcus aureus, Bacillus subtilis, and Micrococcus luteus. Correlation and multivariate statistical analysis were used to identify potential bioactive compounds in the extracts. Twenty-nine metabolites were identified along with 34 other metabolites that were classified into the following classes: triterpenoids (12), acetyltriterpenoids (3), sesquiterpenes (6), steroids (4), and hydrocarbons (9). The antioxidant capacity (IC) ranged from 21.50 to 78.77μg/mL, whereas the content of total phenolic compounds ranged from 31.88 to 204.30mg GAE/g of dry weight. Total phenolic compounds and methyl retinoate showed a positive correlation with the antioxidant capacity, whereas tetradecanal, γ-palmitolactone and ethyl hydrocinnamate showed a negative correlation. Different sets of metabolites are shown to correlate with the antibacterial activity of the extracts, which is largely dependent on the type of microorganism. This innovative approach allowed us to identify likely bioactive compounds in the extracts, although the mechanism(s) underlying antibacterial activity encompass a complex trait, which might involve synergistic effects.
