Composition of the volatile fraction of a sample of Brazilian green propolic and its phytotoxic activity

Abstract

The chemical composition of the volatile fraction of this Brazilian green propolis is different from those previously described, and these results may contribute to a better understanding about the chemical variations in propolis. The volatile fraction of Brazilian green propolis influences both germination of seed lettuce and the growth of its seedlings, showing an phytotoxic potential.

Evaluation of mutagenic and antimicrobial properties of brown propolis essential oil from the Brazilian Cerrado biome

“… c Linear retention indices relative to C8⿿C21 n -alkanes on a Rtx column. d [13] , except for allyl-3-prenylcinnamate [14] . …”

“…Calculation of the percentages of oil components was based on measurements of normalized GC peak areas in relation to the total area of all the sample constituents. Individual constituents were identified by comparison of their GC retention indices (RI, relative to the retention times of a series of C8⿿C21 n -alkanes) [12] and mass spectra with those from the MS library (NIST05/FFNSC) and also from the literature for MS/RI data [13] , [14] . C 8 ⿿C 20 and C 21 n -alkane standards were purchased from Sigma and Fluka, respectively.…”

Brazilian Green Propolis: Chemical Composition of Essential Oil and Their In Vitro Antioxidant, Antibacterial and Antiproliferative Activities

“…Taking into account the pharmacological potential of extracts and EOs extracted from samples of propolis found all over the world [11][12] and, mainly, from samples of EOs and compounds found in Brazilian green propolis [13][14][15][16], this study aimed at determining the chemical composition and in vitro antioxidant, anti-Helicobacter pylori, antimycobacterial and antiproliferative activities of EO from Brazilian green propolis (BGP-EO) found in São Lourenço, a city located in the south of Minas Gerais (MG) state, Brazil.…”

Monoterpenes from the essential oil from Brazilian propolis affect seedling cellular elongation

“…The actual composition depends on the type and locality of the propolis. Phenylpropanoids, either simple or prenylated, have been detected in the essential oil from Brazilian green propolis (Kusumoto et al 2001;Oliveira et al 2010;Fernandes-Silva et al 2015). Reports about biological activity of propolis essential oil are scarce.…”

“…It has been hypothesized that propolis constituents may be templates for the development of environmentally non-aggressive herbicides. Fernandes-Silva et al (2015) noted that the volatile fraction of Brazilian green propolis, containing mainly prenylated phenylpropanoids and sesquiterpenes, inhibits the germination of lettuce seeds and growth of the hypocotylradicular axis of the seedlings.…”
