background and objectives:gamma-irradiation is used vastly for both decontamination and sterilization of natural products; but these high-energy rays can affect heat-sensitive essential oils. methods: the oleo-gum-resin of boswellia carterii (burseraceae) was sterilized by γ-irradiation at dose 30 kgy. the essential oils obtained by hydrodistillation of non-irradiated boswellia (nib) and irradi...

O breu exsudado das espécies de Burseraceae é amplamente utilizado tanto em cosméticos e perfumes quanto na medicina tradicional, para tratamento de diversos males. Amostras de breu de cinco espécies (Protium cf. apiculatum, P. cf. hebetatum, P. cf. heptaphyllum, P. tenuifolium e Trattinnikia peruviana), provenientes da Reserva Biológica Adolfo Ducke (Manaus-AM, Brasil), foram analisadas por FR...

The vast majority of braconid wasps are parasitoids of other insects. Although a few cases of pure phytophagy (primary gall production and seed predation) are known, no previous entomophytophagous species (i.e. ones that display entomophagy and phytophagy sequentially), has been discovered among braconids. We describe the detailed biology and specialized larval morphology for the first confirme...

Six different extracts of Canarium patentinervium Miq. (Burseraceae) leaves and barks were screened for their phytochemical composition, and antimicrobial and free radical scavenging activities. Among the different extracts tested, the ethanol extract of leaves showed significant antimicrobial and radical scavenging activities. The most susceptible micro-organisms were found to be Gram-positive...

Boswellia sacra (Burseraceae), a keystone endemic species, is famous for the production of fragrant oleo-gum resin. However, the genetic make-up especially the genomic information about chloroplast is still unknown. Here, we described for the first time the chloroplast (cp) genome of B. sacra. The complete cp sequence revealed a circular genome of 160,543 bp size with 37.61% GC content. The cp ...
