TL;DR

The key result is that several identified compounds, such as naringin and quercetin, showed strong predicted binding affinities to bacterial, fungal, and antioxidant protein targets.

Full summary

544 CHARS

Extracts from Pistacia lentiscus leaves were prepared using solvents like ethanol and hexane. Chemical composition was analyzed via GC/MS, with linoleic acid identified as a primary compound. The extracts were tested in vitro against bacterial and fungal strains using the agar-diffusion method. Docking results indicated that compounds such as naringin, quercetin, luteolin, and catechin exhibited strong binding affinities (lower docking scores) to several targets, including DNA gyrase and enoyl-ACP reductase, compared to reference ligands.

ABSTRACT

Abstract The mastic tree, scientifically known as Pistacia lentiscus , which belongs to the Anacardiaceae family, was used in this study. The aim of this research was to analyze the chemical composition of this plant and assess its antioxidant and antibacterial properties using both laboratory experiments and computer simulations through molecular docking, a method that predicts the binding strength of a small molecule to a protein. The soxhlet method (SE) was employed to extract substances from the leaves of P. lentiscus found in the eastern region of Morocco. Hexane and methanol were the solvents used for the extraction process. The n-hexane extract was subjected to gas chromatography-mass spectrometry (GC/MS) to identify its fatty acid content. The methanolic extract underwent high-performance liquid chromatography with a diode-array detector (HPLC-DAD) to determine the presence of phenolic compounds. Antioxidant activity was assessed using the DPPH spectrophotometric test. The findings revealed that the main components in the n-hexane extract were linoleic acid (40.97 ± 0.33%), oleic acid (23.69 ± 0.12%), and palmitic acid (22.83 ± 0.10%). Catechin (37.05 ± 0.15%) was identified as the predominant compound in the methanolic extract through HPLC analysis. The methanolic extract exhibited significant DPPH radical scavenging, with an IC50 value of 0.26 ± 0.14 mg/mL. The antibacterial activity was tested against Staphylococcus aureus , Listeria innocua , and Escherichia coli , while the antifungal activity was evaluated against Geotrichum candidum and Rhodotorula glutinis . The P. lentiscus extract demonstrated notable antimicrobial effects. Additionally, apart from molecular docking, other important factors, such as drug similarity, drug metabolism and distribution within the body, potential adverse effects, and impact on bodily systems, were considered for the substances derived from P. lentiscus . Scientific algorithms, such as Prediction of Activity Spectra for Substances (PASS), Absorption, Distribution, Metabolism, Excretion (ADME), and Pro-Tox II, were utilized for this assessment. The results obtained from this research support the traditional medicinal usage of P. lentiscus and suggest its potential for drug development.
