The present paper describes the antifungal activity of some plant extracts on the development of Fusarium oxysporum f.sp. lycopersici. The best extracts were selected to be tested as a phytofungicide to control crop diseases, with the ultimate goal of developing a green alternative to synthetic fungicides. Using the conidia germination assay, of the 24 plant extracts tested, 15 reduced conidia germination and 6 completely inhibited germination. Extracts of Rivina humulis, Brassica carinata, Brunfelsia calyicina, Salvia guaranitica and Punica granatum showed good antifungal activity. The relationship between total phenolic content (TPC) in each plant extract tested and the percentage of mycelial growth inhibition showed a significant correlation (R2 = 0.69), while no correlation was found between total flavonoid content (TFC) and percentage mycelial growth inhibition. Among all extracts tested, Punica granatum and Salvia guaranitica showed the best inhibitory effect against Fusarium oxysporum f.sp. lycopersici . Our results indicate that plant extracts with a good antifungal activity generally had a high level of total polyphenolic content and titratable acidity, and low values of pH.

“…There are a positive correlation between total phenolic and flavonoid contents and the antioxidant and antimicrobial activities. The positive correlation between total phenolic and flavonoid contents and the antioxidant effects were observed for Azilia eryngioides ethanol extract (13), while this correlation was reverse for Sambucus nigra extracts (14). Therefore, the direct correlation between total phenolic content of extract and its antioxidant activity is not an absolute relation.…”

“…showed more sensitivity to P. spinosa extracts, especially to its ethanol extract. A higher total phenolic content and consequently, a higher antimicrobial activity against fungi was detected for A. eryngioides (13), while P. spinosa ethanol extract showed less activity against Gram-negative bacteria and fungi. Therefore, different phenolic compounds target different functions of microbial cells.…”

Background: Pycnocycla spinosa (P. spinosa) a member of the Umbelliferae family is traditionally used for treatment of different ailments. Objectives: This study aimed to evaluate the total phenolic and flavonoid content of P. spinosa extracts (methanol, ethanol and aqueous) and their antioxidant and antimicrobial effects. Materials and Methods:The antimicrobial activity of different extracts of P. spinosa was evaluated using micro broth dilution. Total phenolic and flavonoid contents were measured. Their antioxidant effect was evaluated using DPPH assay and β-carotene linoleic acid test. Results: P. spinosa ethanol extract with higher-level phenolic and flavonoid contents showed the highest antioxidant and antimicrobial effects, in comparison with the other extracts. Bacillus sp. and Streptococcus sp. showed higher sensitivity to P. spinosa ethanol extract. Conclusions: P. spinosa ethanol extract can be used as a mouthwash for treatment of the oral infections. More clinical and toxicological studies are required for providing its efficacy.

Varthemia persica DC (Asteraceae) is an aromatic plant that grows wild in central parts of Iran. The aim of this study was to evaluate the antioxidant and antimicrobial activity of V. persica extracts in vitro, also, the relation between the total phenolic (TPC) and flavonoid contents (TFC) of each extract and its antimicrobial and antioxidant activities. The amount of TPC and TFC was higher in V. persica ethanol extract, followed by methanol and aqueous extracts, respectively. The lower IC 50 was for V. persica ethanol extract (82 μg/ml), followed by methanol extract (145 μg/ml) and aqueous extract (550 μg/ml) and these amounts were higher than BHT (Butylated hydroxytoluene) (20 μg/ml). The result of antimicrobial screening exhibited that the antimicrobial activity of V. persica ethanol extract was higher than that of methanol extract followed by its aqueous extract. Therefore, there is a positive relation between TPC and TFC of V. persica extracts and their antioxidant and antimicrobial activities. Other studies are required for its application in different industries especially as antioxidant agent.
