Lindy Mpala1, Getmore Chikowe1, Ian E Cock1,2,*1School of Environment and Science, Nathan Campus, Griffith University, Brisbane, Queensland, AUSTRALIA.2Centre for Planetary Health and Food Security, Griffith University, Brisbane, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.4.26 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 genus are known to possess therapeutic properties. The genus Citrus has a long history of ethnobotanbical usage in many areas of the world. Many species are known to have therapeutic properties, several species of which have well established antibacterial bioactivities. Materials and…

Aiden Wood1, Ian Edwin Cock1,2,* 1School of Environment and Science, Nathan Campus, Griffith University, Brisbane, AUSTRALIA.2Centre for Planetary Health and Food Security, Nathan Campus, Griffith University, Brisbane, AUSTRALIA.DOI:10.5530/pc.2022.4.27 ABSTRACT Introduction: Many high antioxidant fruit extracts can inhibit the growth of multiple 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 for many Australian native fruits. Materials and Methods: Methanolic and aqueous K. pomifera and P. elatus fruit extracts were investigated by disc diffusion and liquid dilution MIC assays against the most significant bacterial contributors…
Jason Batten, I E Cock1,2,* 1School of Environment and Science, Nathan Campus, Griffith University, Nathan, Brisbane, Queensland, AUSTRALIA. 2Centre for Planetary Health and Food Security, Griffith University, Nathan, Brisbane, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.4.28 ABSTRACT Introduction: The recent development of extensively antibiotic resistant bacteria has necessitated the search for novel antibacterial compounds. An examination of aromatic plants and traditional medicines is an attractive option for drug discovery. Andrographis paniculata (Burm.f.) Nees is used in southern Asian traditional medicine for a variety of purposes and has been reported to have antibacterial activity against a limited panel of bacteria. Methods: The ability of A.…
Vimal Temkar1,*, Sasikumar Menon2 1Department of Zoology, Ramnarain Ruia Autonomous College, Mumbai, Maharashtra, INDIA.2TDM Lab, Sion, Mumbai, Maharashtra, INDIA.DOI: 10.5530/pc.2022.4.29 ABSTRACT Background: Polycystic ovarian syndrome (PCOS) is a heterogeneous reproductive disorder and the most common endocrinopathy that leads to anovulatory infertility. PCOS is associated with wide spectrum of complications in various health aspects including anovulation, hyperandrogenism, hirsutism, infertility and menstrual disturbance. Metabolic dysfunctions like obesity, dyslipidemia, diabetes mellitus, cardiovascular risk and changes in psychological feature such as mood disorders and decreased quality of life are also associated with PCOS. Disruption in secretion rates and metabolism of androgens, estrogens and other…
I E Cock1,2,* 1School of Environment and Science, Nathan Campus, Griffith University, Brisbane, Queensland, AUSTRALIA. 2Centre for Planetary Health and Food Security, Nathan Campus, Griffith University, Nathan, Brisbane, Queensland, AUSTRALIA.DOI: 10.5530/pc.2022.4.30 ABSTRACT Whilst the range of SARS-CoV-2 vaccines introduced globally since the start of the current pandemic have dramatically reduced the adverse effects of the disease and stemmed the spread of the virus, there is still a need for chemotherapies to relieve the symptoms of the disease and to further decrease its spread. Traditional medicines may provide drug leads to treat COVID-19 and I have previously highlighted several plant species…

C. Sm. (family Winteraceae), commonly known as Tasmanian pepper or mountain pepper berry, is shrub which is endemic to the woodlands and cool temperate rainforests of Tasmania and the south-eastern region of the Australian mainland. The leaves, berries and bark of this plant have traditional uses as a food flavouring, and as a medicinal plant. Australian Aborigines used T. lanceolata as a therapeutic agent to…

DOI: 10.5530/pc.2022.3.18 I am pleased to bring you volume 12, issue 3 of Pharmacognosy Communications. In this issue, we present an evaluation of the antioxidant and peroxidase inhibitory activity of Triclisia gilletti (De Wild) Staner decoction. We also present new research reports examining the antibacterial properties of Rheum palmatum L root extracts against some bacterial triggers of autoimmune diseases, and the interactive effects of the extracts in combination with conventional antibiotics.…

DOI: 10.5530/pc.2022.3.19 ABSTRACT Introduction: The recent development of extensively antibiotic resistant bacteria has necessitated the search for novel antibacterial therapies. An examination of aromatic plants and traditional medicines is an attractive option for drug discovery. Terminalia sericea Burch. ex DC. is a southern African native species, which has been reported to have antibacterial activity, although the effects of storage on the activity is yet to be determined.…

Medicinal plant extracts may provide leads for the development of new topical and/or oral therapies for acnes vulgaris, yet many traditional medicine plants are yet to be screened for growth inhibitory activity against Cutibacterium acnes (the major bacterial cause of acne). Materials and Methods: Methanolic and aqueous Scaevola spinescens R.Br. leaf extracts were investigated by disc diffusion…
