Pharmacognosy Communications,2019,9,3,85-90.DOI:10.5530/pc.2019.3.18Published:June 2019Type:Original Article ABSTRACT Introduction: The medicinal benefits from inhalation of Cannabis sativa phytochemicals have been extensively reported. Whilst in-silico models are available for prediction of phytochemical pharmacokinetics post-ingestion, no models are available to accurately predict inhalation pharmacokinetics. Therefore, the aim of this study was to explore the relationship between phytochemical physicochemical properties and inhalation pharmacokinetics and to develop an in-silico model for predicting the time of maximal compound concentration in plasma (Tmax) and compound elimination half-life (T½), following inhalation.…

Pharmacognosy Communications,,2019,9,3,100-105.DOI:10.5530/pc.2019.3.21Published:June 2019Type:Original Article ABSTRACT Introduction: Closely related plant species often share similar secondary metabolites and bioactivities and are therefore good targets for bioactivity testing when one or more species within a family are known to possess therapeutic properties. The family Lamiaceae has a long history of medicinal usage globally. Many species are known to have therapeutic properties, several species of which have well established…

White is a rainforest tree that is native to north-eastern regions of Australia. X. fragrans leaf extracts were examined for the ability to inhibit the growth of Pseudomonas aeruginosa. Methods: The antimicrobial activity of a methanolic X. fragrans leaf extracts were investigated by disc diffusion and growth time course assays against P. aeruginosa. The growth inhibitory activity was further quantified by MIC determination. Toxicity was determined using…

Pharmacognosy Communications,2019,9,3,118-120.DOI:10.5530/pc.2019.3.24Published:June 2019Type:The Janus Corner ABSTRACT The neurotoxins (BoNTs) produced by the anaerobic bacterium Clostridium botulinium are amongst the most poisonous proteins known. These toxins block neurotransmitter release by cleaving N-ethylmaleimide-sensitive factor attachment receptor (SNARE) proteins, inducing paralysis. In a recent study published in Applied and Environmental Microbiology,1 300 natural compounds isolated from a panel of Indian medicinal plants were screened by biochemical and cellular assays for the ability to…

Several Grevillea spp. were used traditionally to treat pathogenic illness and are rich in phytocompounds with antibacterial activity. Despite this, the antibacterial activity of Australian Grevillea spp. extracts have not been extensively examined. Methods: The ability of G. juncifolia and G. robusta leaf and flower extracts to inhibit the growth of gram-negative and gram-positive bacterial species and some…
