Antioxidant And Antimicrobial Activity

  Objectives: Paris polyphylla Sm. is a very important anti-cancerous plant species found in the Himalayan region of India. The present study was carried out to determine the phenolic and flavonoid content, antioxidant and antimicrobial activity of its rhizome.Methods: Antioxidant activity of rhizome extract was evaluated through 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. Antimicrobial activity was evaluated through disc diffusion assay against two bacterial and two fungal strains. The bacterial species used in the present study were Escherichia coli and Staphylococcus aureus and the fungal strains used were Aspergillus niger and Trichoderma reesei. Results: The standard curve of Gallic acid revealed that the phenolic content of our sample is 43.01±0.17 mg Gallic acid equivalents (GAE)/g dry weight (DW). Similarly, flavonoids were obtained as 28±0.12 mg quercetin equivalent/g DW of the sample. It was observed that the methanolic rhizome extract showed higher antioxidant potential than water extract with the IC50 value of 1.09 mg/ml. Further, the rhizome extract of P. polyphylla species exhibited significant antimicrobial activity and it was observed that at concentration of 5 mg/ml of the sample, the percentage inhibition was 95-97% in E. coli, S. aureus and A. niger whereas in case of T. reesei it was 74%.Conclusion: This study is first of its kind in the Indian subcontinent on this plant species and these findings indicate the tremendous and promising potential of this wonder herb. A lot of work has already been done in China on this species, therefore, further studies are required for the conservation and sustainable use in Indian subcontinent before this species is thrown into extinction as it has already been declared vulnerable.

Two terpenoids, β-amyrin (1) and β-sitostenone (2) and a coumarin, scopoletin (3) were isolated from petroleum ether and dichloromethane soluble extracts of the stem bark of Bursera serrata Wall. The structures of the isolated compounds 1-3 were established by extensive spectroscopic studies as well as by comparison with published data. Although compounds 1-3 have been isolated from various plant species previously, this is the first report of the occurrence of these compounds from B. serrata. The crude extractives exhibited weak antimicrobial activity and cytotoxicity.

Brazilian Biodiversity

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
