Introduction: The present study was designed to screen out the different proteins from Prosopis cineraria (Leaves), known as Shammi (Family Fabaceae) and characterize them by IR, NMR and mass spectrometry and evaluate their antimicrobial potential against various microbial species. Methods: Different leaf extracts were treated with different reagent for the presence and absence of various secondary metabolites. Screening of proteins have been done by electrophoresis. Antimicrobial effects of the proteins were explored against Staphylococcus aureus, Pseudomonas aeruginosa and Aspergillus tubingensis. The disc diffusion method was used for determination of antimicrobial effects. Analytical analysis included infrared spectroscopy, nuclear magnetic spectroscopy and mass spectrometry. Results: Phytochemical analysis of different extracts showed the presence of different secondary metabolite including alkaloids, glycosides, tannins, proteins, saponin, phenolic compounds etc. Various proteins were detected with different molecular weights of 10, 25, 30, 35, 48, 50, 55 and 70 KDa. The range of zone of inhibition was 1.4±0.01mm to 14.2±0.18 mm. The maximum activity inhibitory activity was found to be due to the 50 KDa protein against Pseudomonas aeruginosa. Analytical analysis revealed the presence of various functional groups in the proteins. Conclusion: The data generated would be useful for the preparation of monograph of the plant.

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
