Phytochemical Screening and Antibacterial Activity of Pistacia atlantica and Pinus canariensis Extracts

Abstract

The detection qualitative of Phytochemical compounds of extracts was carried out using color reagents, total content of phenols and flavonoids was specified using folin– ciocalteu and aluminium chloride method, respectively, and antioxidant activity was determined through its ability to free radicals scavenging using DPPH radical. The efficacy of the plant extracts against pathogenic bacteria was studied by agar well diffusion method with different concentrations, and microdilution method was used to measure minimum inhibitory concentration (MIC) of all plant extracts. The results showed presence of tannins, phenols, and flavonoids in all extracts of both plants, while saponins were found in aqueous extracts only, cardiac glycosides and coumarins were absent in all plant extracts. Ethanolic extract of Pistacia atlantica recorded the highest content of phenols and flavonoids as 263.76 ± 0.53 (mg GAE/g Dw) and 46.83 ± 0.55 (mg RE/g Dw), respectively. While aqueous extract of Pinus canariensis recorded the lowest content of of phenols and flavonoids 30.11 ± 0.37 (mg GAE/g Dw) and 5.43 ± 0.38 (mg RE/g Dw), respectively. Both plants have been shown to have good antioxidant activity, as ethanolic extract of P. atlantica recorded the best ability to free radicals scavenging 90.27% ±1.51, ethanolic extracts of both plants were the most effective in inhibiting bacteria especially at high concentrations (500 mg/mL); the inhibition zone diameter of P. atlantica extract was reached against Shigella boydii 33.56 mm, while aqueous extract of P. canariensis was the most effective against Pseudomonas aeruginosa; the inhibition zone diameter was 21 mm. MIC ranged between 5.468 and 43.75 mg/mL depending on plant extract and bacterial species. This confirms the importance of plant extracts as a natural source of antibacterial to confront problems of increasing bacterial resistance to antibiotics that threaten public health.
