Evaluation of bio-fungicidal properties of some plant extracts on the growth of Schizophyllum commune

Abstract: Biofungicidal properties of different plant extracts on the growth of Schizophyllum commune were evaluated. Dried leaves of Ageratum conyzoides, Azadirachta Indica, Bryophyllum sp. Carum copticum, Catharanthus roseus. Ocimum sanctum, Parthenium hysterophorus, Withania somnifera, and stem of Cuscuta reflexa were used against the mycelial growth. Maximum inhibition of fungal growth was recorded in Cuscuta reflexa (98%) followed by Ageratum conyzoldes (81%), where as Withania somnifera was least effective (24%). However, Catharanthus roseus was found to be a growth enhancer (-90%).

Comparative Analysis of Antioxidant Properties of Different Medicinal and Non-Medicinal Plants.

Abstract: The crude methanolic leaf extracts of Artemisia annua, Withania somnifera and Brassica juncea was studied to evaluate and compare their antioxidant activity by the using in-vitro methods. The extracts was found to contain significant amount of phenols and had high antioxidant potential as found in Folin- Ciocalteau assay, DPPH free radical scavenging assay and β-Carotene bleaching assay. The total phenolic contents of the extracts varied from 53.7 mg/gm in Brassica juncea to 69.34mg/gm in Withania somnifera and 72.32mg/gm in Artemisia annua. The DPPH free radical scavenging activity shows that Withania somnifera has 78.18% scavenging effect while Artemisia annua and Brassica juncea showed 66.7% and 56.36 %respectively. The βcarotene bleaching of these plant extracts showed the presence of significant amounts of antioxidants. The total antioxidant content found in the leaf extracts was found to be 193.6 mg/gm dry weight in Artemisia
