Audric Puisais1, Ian E Cock1,2,*1School of Environment and Science, Griffith University, Nathan, Queensland, AUSTRALIA.2Centre for Planetary Health and Food Security, Nathan Campus, Griffith University, Nathan, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.2.14 ABSTRACT Background: Curcumin, lupeol and piperine are phytochemical constituents of multiple plants that are used traditionally to treat inflammation, including for treating autoimmune inflammatory diseases. Despite this, relatively few studies have examined the ability of these compounds to inhibit the etiological events of these diseases by examining their ability to inhibit their bacterial triggers. Methods: The ability of curcumin, lupeol and piperine to inhibit the growth of some bacterial triggers of selected…

Aiden Wood1, Ian E Cock1,2,*1School of Environment and Science, Griffith University, Nathan, Queensland, AUSTRALIA.2Centre for Planetary Health and Food Security, Nathan Campus, Griffith University, Nathan, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.2.15 ABSTRACT Introduction: Tasmannia spp. extracts inhibit the growth of many bacterial pathogens. They may also inhibit the growth of malodour producing bacteria and thus be useful deodorant components, although this is yet to be tested. Methods: T. lanceolata and T. insipida fruit and leaf solvent extracts were investigated by disc diffusion and liquid dilution MIC assays against the most significant bacterial contributors to axillary and plantar malodour formation. Toxicity was determined using…

Australian Aborigines used T. lanceolata as a therapeutic agent to treat stomach disorders and as an emetic, as well as general usage as a tonic. That study reported that T. lanceolata was used by Australian Aborigines for the treatment and cure of…

I.E. Cock1,2,*Editor-In-Chief1Centre for Planetary Health and food Security, Nathan Campus, Griffith University, Brisbane, Queensland, AUSTRALIA.2School of Natural Sciences, Nathan Campus, Griffith University, Brisbane, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.1.1 Dear Readers and Authors, I am pleased to bring you Volume 12, Issue 1 of Pharmacognosy Communications. In this issue, we present a review on the uses of mucilage for industrial processes. We also present new research reports examining the antimalarial properties and phytochemistry of Streptomyces hygroscopicus, the antibacterial activity of the southern African plant Harpagophytum procumbens (commonly known as Devil’s claw) against bacterial gastrointestinal pathogens, as well as bacteruial triggers our some autoimmune…

Veteran, Malang, INDONESIA.DOI: 10.5530/pc.2022.1.2 ABSTRACT Background: Malaria has become a major global health disease among humans. Globally, an estimated 228 million cases of malaria occurred and resulted in 405,000 deaths in 2018. The treatment of Plasmodium falciparum malaria relies on derivatives of artemisinin (ART) as a core component of ART-based…

Methods: This bibliographic review compiles documents printed before December 2020, were searched using Elsevier and Google Scholar databases. Studies that examined mucilages that were not derived from plants were excluded from this review. Results: Mucilages have…

Alysha Bromley1, Ian E Cock1,2,* 1School of Environment and Science, Griffith University, Nathan, Queensland, AUSTRALIA. 2Centre for Planetary Health and Food Security, Nathan Campus, Griffith University, Nathan, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.1.4 ABSTRACT Background: Recent increases in the numbers of antibiotic resistant bacteria and corresponding decreases in antimicrobial discovery have focussed drug discovery efforts towards plant based medicines. Harpagophytum procumbens has been used in southern African traditional medicine for a variety of conditions including inflammation, and to treat bacterial infections. Despite this, investigations of the antibacterial activity of H. procumbens root extracts have been relatively neglected. Materials and Methods: The antimicrobial activity…

Getmore Rumbudzai Chikowe1, Lindiwe Nomathemba Mpala1, I E Cock1,2,* 1Environmental Futures Research Institute, Griffith University, Brisbane, Queensland, AUSTRALIA. 2School of Environment and Science, Nathan Campus, Griffith University, Brisbane, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.1.5 ABSTRACT Introduction: The development of bacterial strains that are resistant to multiple antibiotics has made the discovery of new antibiotics a priority for medical research. Examination of plants for new antimicrobial agents is an attractive prospect and numerous recent studies have screened plants for antibacterial activity. Despite this, many plant species are yet to be tested for antibacterial activity. Lomandra hystrix Labill. is a perennial rhizomatus herb of the…
