This study evaluated the volatile components of Cannabis sativa L. essential oils (CSEOs) and their pharmacological potential in vitro, in animal, and in silico. The anti-oxidant capacities of volatile compounds were tested using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), total anti-oxidant capacity (TAC), and gas chromatography-mass spectrometry (GC-MS). Anti-microbial activity against bacterial and fungal strains was assessed using disk diffusion and micro-dilution, and acute toxicity was examined on mice using OECD 423 criteria. The results indicate that the main components were β-caryophyllene (31.54%), α-humulene (12.62%), β-myrcene (4.83%), and α-pinene (4.69%). The essential oil showed high anti-oxidant ability (IC50 = 0.981 ± 0.059 mg/ml for DPPH, EC50 = 1.74 ± 0.05 for FRAP), and TAC of 0.101 ± 0.001 mg AAE/g. Additionally, it showed significant antibacterial action against Gram-negative organisms, such as Escherichia coli (11.33 ± 0.00 mm), Klebsiella pneumonia (9 ± 0.00 mm), and Pseudomonas aeruginosa (9.34 ± 0.00), with MICs ranging from 0.0052 to 0.0208 mg/CSEO demonstrated antifungal activity against Candida albicans and Fusarium proliferatum, with activity levels of 18.66 ± 0.88 mm, 41.89 ± 3.60%, and MICs of 0.39 and 0.013 mg/ml, respectively. In toxicological studies, CSEO proved to be safe for animals. Docking identified bioactive components and explored anti-oxidant and antibacterial properties. Docking proved that bulnesol and champacol caused indicated actions.

Cytisus villosus Pourr. (C. villosus) is a medicinal plant belonging to the Fabaceae family, which grows in the Mediterranean area. It is used in traditional medicine against diseases related to inflammation. The objective of the present study was to identify the mineral and polyphenolic composition as well as to evaluate some biological properties including antioxidant, anti-inflammatory, and analgesic activities of C. villosus leaf aqueous extract. The chemical constituents were identified and quantified using ultra performance liquid chromatography-electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) methods. The antioxidant properties of C. villosus leaves were tested using reducing power (RP), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and 2,2′-diphenyl-1-picrylhydrazyl (DPPH) assays. The anti-inflammatory potency was evaluated in vitro and in vivo using the albumin denaturation test and the carrageenan test, respectively. Furthermore, the analgesic effect was performed in vivo using tail flick, acetic acid-induced contortion, and plantar tests. Mineralogical analysis revealed that potassium and calcium were the most abundant minerals. The analysis and quantification of the phytochemical composition using UPLC-ESI-MS/MS showed that quinic acid (57.478 ± 1.72 mg/kg) was the major compound of the aqueous extract, followed by salicylic acid (17.38 ± 0.2 mg/kg), isoquercetin (16.895 ± 1.01 mg/kg), and gallic acid (15.914 ± 1.51 mg/kg). The extracts showed potent antioxidant activity for all tests used. The highest antioxidant activity was recorded for the DPPH, ABTS and RP methods, with an IC50 of 3.94 ± 0.09, 2.88 ± 0.07, and 1.94 ± 0.10 μg/mL, respectively. Additionally, using the most frequent analgesic assays, the aqueous extract at a dose of 500 mg/kg exhibited a potent analgesic activity. Notably, an interesting inhibition of albumin denaturation was recorded with an IC50 of 383.94 μg/mL, corroborating the in vivo test. Overall, the results presented here may represent a scientific basis for the traditional use of C. villosus in the treatment of inflammation-related diseases.
