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, Australian native plants have been relatively neglected. Mirbelia oxylobioides F.Muell. is a native Australian shrub of the family Fabaceae. Very few studies have yet examined species for antibacterial properties against human pathogens. Methods: The ability of M. oxyloboides leaf extracts to inhibit the growth of a panel of bacterial pathogens was investigated by disc diffusion assay. Toxicity was examined using the Artemia franciscana nauplii bioassay. Results: M. oxyloboides methanolic and aqueous extracts were ineffective at inhibiting the growth of gram-positive and gram-negative panels of bacteria. The extracts were nontoxic or of low toxicity following 24 h exposure. Conclusion: The M. oxyloboides leaf extracts lacked growth inhibitory bioactivity against a panel of pathogenic bacteria and were nontoxic in the Artemia nauplii assay. However, these extracts may have other therapeutic properties and testing against protozoa, fungi, virus and tumour cells is required.

Founded:  In 2004, as the PHCOG.NET – a non-profit private organization dedicated to Natural Products Research leading to develop promising drugs. Our main mission is to make information on herbal drug research readily available in different formats to suit the individual needs.

Pharmacognosy Communications [Phcog Commn.] is a new quarterly journal published by Phcog.Net. It is a peer reviewed journal aiming to publish high quality original research articles, methods, techniques and evaluation reports, critical reviews, short communications, commentaries and editorials of all aspects of medicinal plant research. The journal is aimed at a broad readership, publishing articles on all aspects of pharmacognosy, and related fields. The journal aims to increase understanding of pharmacognosy as well as to direct and foster further research through the dissemination of scientific information by the  publication of manuscripts. The submission of original contributions in all areas of pharmacognosy are welcome.

The journal aims to cater the latest outstanding developments in the field of pharmacognosy and natural products and drug design covering but not limited to the following topics:

  • Pharmacognosy and pharmacognistic investigations
  • Research based ethnopharmacological evaluations
  • Biological evaluation of crude extracts, essential oils and pure isolates
  • Natural product discovery and evaluation
  • Mechanistic studies
  • Method and technique development and evaluation
  • Isolation, identification and structural elucidation of natural products
  • Synthesis and transformation studies

Distinctions:  The most widely read, cited, and known Pharmacognosy Communications and website is well browsed with all the articles published. More than 20,000 readers in nearly every country in the world each month
