In order to investigate the antioxidant activity of Salvia nemorosa L. collected from Ahar and Urmia regions in Iran at different growth stages, aerial parts of sage after collecting were dried, and for measurement, the ability of scavenge DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) radical in different concentrations (0.025, 0.05, 0.07, 0.1, 0.2, 0.04 and 0.6) of methanolic extracts were prepared. The result showed that the ability to scavenge DPPH radical and amount of inhibition percent of vegetative stage leaves, flowering stage leaves, and flowers increased with increasing concentrations of methanolic extracts from 0.25 to 0.6 mg/ml. In the region of Urmia, the highest amount of DPPH inhibition there was in vegetative stage leaves, and the lowest amount of DPPH inhibition was seen in flowers. In Ahar regions, unlike the Urmia region, the highest amount of DPPH inhibition there was in flowers, but the lowest of DPPH inhibition was seen in flowering stage leaves. Also, the content of inhibition of DPPH in Ahar and Urmia regions similarly increased between two phenological stages (vegetative stage leaves, flowering stage leaves, and flowers) in 0.4 mg/ml and 0.6 mg/ml concentrations

Plant extracts are an important alternative to antibiotics, which are ever more restricted because of their developing microbial resistance and some adverse effects that have been observed following frequent application. The aim of the present study was to determine the antifungal and antioxidant activity of the methanolic extracts of Acorus calamus, Chlorella vulgaris, Lemna minuta and Scenedesmus dimorphus. The antifungal activity of the extracts against strains of Aspergillus flavus, Aspergillus parasiticus, Aspergillus ochraceus, Aspergillus niger, Aspergillus carbonarius, Fusarium graminearum, Fusarium oxysporum, Penicillium chrysogenum and Alternaria alternata was evaluated via the agar well diffusion method. The antioxidant activity of the extracts was measured through the determination of three parameters—total phenolic content, total flavonoid content and radical scavenging potential (determined through UV/Vis analysis). A. calamus extracts had the highest antimicrobial activity against eight fungal strains, followed by the C. vulgaris, L. minuta and S. dimorphus extracts, which were inhibitory against two to three strains. Among the extracts from the species studied, the extract from S. dimorphus showed the highest antioxidant potential, as determined via the DPPH (1,1’-diphenyl-2-picrylhydrazil-radical) method. This correlated to its high total phenolic and flavonoid content. From A. calamus and L. minuta, methanolic extracts were obtained that exhibited similar values of the aforementioned parameters, followed by C. vulgaris extracts, which showed the lowest antioxidant activity. Based on the Pearson correlation coefficients, the impacts of the total phenolic content and the total flavonoid content on radical scavenging capacity are similar, and flavonoids were a significant part of the total phenolic compounds extracted from the plant materials studied.
