Aim: This study was designed to investigate the phytochemical profile and the cytotoxic activities of the eco-friendly extracts of olive leaves from Chemlali cultivar. Materials and Methods: The Phenolic composition of olive leaves extracts, the antioxidant activity and the cytotoxic effects against MCF-7 and HepG2 cells were determined. Results: Olive leaves extracts showed relevant total polyphenols contents. Oleuropein was the major detected phenolic compound reaching a concentration of 16.9 mg/ml. The antioxidant potential of the studied extracts varied from 23.7 to 46.5mM Trolox equivalents as revealed by DPPH and ABTS assays. Cytotoxicity experiments showed similar trends for both HepG2 and MCF-7 cells with the infusion extract being the most active. Conclusion: This study denotes that olive leaves may have great potential as endless bioresource of valuable bioactive compounds which may have a wide application.

AbstractObjectivesIn this study, we aimed to detect the chemical compounds of Thymbra capitata ethanolic extract (TC-EtOH) as well as to evaluated its antimicrobial, antioxidant, cytotoxic activities, and in vivo wound healing effects.MethodsThe chemical composition of TC-EtOH was analyzed by Gas chromatography-mass spectrometry (GC-MS). Antioxidant and antimicrobial properties were determined with 2,2-diphenyl-1-picrylhydrazyl (DPPH), disc diffusion test and broth micro-dilution (minimal inhibitory concentration [MIC]) methods, respectively. Cytotoxic activity was tested on MG63 (human osteosarcoma) and MCF-7 (human breast carcinoma) cells by 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assay. Tumor necrosis factor alpha (TNF-α) protein levels were determined by ELISA.ResultsThe major components of TC-EtOH were tetratria contane (14.92%), camphor (12.50%), and terpineol (10.77%). TC-EtOH showed powerful antimicrobial activity in C. Tropicalis (0.03 mg/mL). The IC50 values of the TC-EtOH of the DPPH were determined 21.5 μg/mL. The IC50 values were calculated 37.28 and 44.40 μg/mL on the MG63 and MCF-7 cell lines, respectively. It was observed that the wounds treated with TC-EtOH showed a faster healing.ConclusionsAccording to results, T. capitata species are thought to be natural antioxidants and a novel pharmaceutical compound for the pharmaceutical industry.

Sage (Salvia officinalis) is the best-known species of the genus Salvia, due to its medicinal and flavouring properties. This research was conducted on samples of S. officinalis collected from Potoci (SOP) in the continental part of Montenegro and from Valdanos (SOV) and Lustica (SOL) in the country?s coastal region. Extracts prepared using 96% ethanol, 50% ethanol and hot distilled water were examined for phenolic composition, as well as for their antioxidant, enzyme-inhibiting and cytotoxic activities. The HPLC-DAD method was employed for quantitative-qualitative analysis of phenolic compounds in extracts, which confirmed the presence of rosmarinic and caffeic acids and luteolin-7-O-glucoside. Total phenolic and flavonoid contents, antioxidant activity, and inhibition of acetylcholinesterase and tyrosinase were measured spectrophotometrically. In the applied antioxidant tests (DPPH, FRAP and ?-carotene/linoleic acid tests) and tests of inhibition of the enzymes acetylcholinesterase and tyrosinase, the SOP extracts showed stronger antioxidant and enzyme-inhibiting activities compared to SOV and SOL, while the most efficient solvent was 50% ethanol. The highest cytotoxic activity in the MTT test was recorded for 96% ethanol extracts, especially in the case of the SOL sample, against the A375 cell line. All of the tested bioactivities were more strongly correlated with total phenolic content than with flavonoid content. Differences in the tested bioactivities of extracts obtained from plants collected at ecologically different localities and with different extraction solvents could be explained by variations in total phenolic and flavonoid contents.

Biological assays that have been performed on different types of Brazilian propolis have shown that type 6 propolis (G6) has a strong antimicrobial activity and a low flavonoid content. This study aimed to evaluate the correlation between the phenolic composition and the biological activities displayed by propolis G6 from the state of Bahia and green propolis, also known as type 12 (G12). The values of the flavonoids and the total phenolics in propolis G6 were different than those in propolis G12. Although the G12 variety presented greater antioxidant activity, propolis G6 proved to have greater antimicrobial and cytotoxic activities. The results showed that the phenolic compounds may not be the only compounds responsible for the biological activity. More detailed studies of the chemical composition and an assessment of the biological activity are required to establish the quality of propolis.

Asclepias linaria Cav. (Apocynaceae) is a shrubby plant endemic of Mexico which has been used in traditional medicine. However, the bioactive potential of this plant remains unexplored. In this study, the phenolic composition, antioxidant, and cytotoxic activities of A. linaria leaves were determined. In order to estimate the phenolic composition of the leaves, the total phenolic, flavonoid, and condensed tannins contents were determined. Furthermore, the antioxidant activity was measured by the scavenging activity of the 2,2-diphenyl-1-picrylhydrazyl (DPPH•) and 2,2′-azino-bis[3-ethylbenzothiazoline-6-sulphonic acid] (ABTS•+) radicals and the total antioxidant capacity. The phenolic compounds identified in the A. linaria leaves by ultra-performance liquid chromatography coupled to mass spectrometry (UPLC-MS) include phenolic acids, such as p-coumaric and ferulic acid, as well as flavonoids, such as rutin and quercetin. The leaves’ extracts of A. linaria showed a high scavenging activity of DPPH• and ABTS•+ radicals (IC50 0.12 ± 0.001 and 0.51 ± 0.003 µg/mL, respectively), high total antioxidant capacity values (99.77 ± 4.32 mg of ascorbic acid equivalents/g of dry tissue), and had a cytotoxic effect against K562 and HL60 hematologic neoplasia cells lines, but no toxicity towards the normal mononuclear cell line was observed. These results highlight the potential of A. linaria and could be considered as a possible alternative source of anticancer compounds.

Ethanol extract and fractions obtained from leaves ofSolanum lycocarpumwere examined in order to determine their phenolic composition, antioxidant, antibacterial, anti-inflammatory, and cytotoxic potential. High performance liquid chromatography coupled with DAD analysis indicated that the flavonoids apigenin and kaempferol were the main phenolic compounds present in dichloromethane and ethyl acetate fractions, respectively. The antioxidant activity was significantly more pronounced for dichloromethane, ethyl acetate, and hydroethanol fractions than that of the commercial antioxidant 2,6-di-tert-butyl-4-methylphenol. The hexane and dichloromethane fractions were more active against the tested bacteria. The hydroethanol fraction exhibited significant anti-inflammatory activity at the dose of 75 and 150 mg/kg in the later phase of inflammation. However, the antiedematogenic effect of the higher dose of the ethyl acetate fraction (150 mg/kg) was more pronounced. The ethyl acetate fraction also presented a less cytotoxic effect than the ethanol extract and other fractions. These activities found inS. lycocarpumleaves can be attributed, at least in part, to the presence of phenolic constituents such as flavonoids. This work provided the knowledge of phenolic composition in the extract and fractions and the antioxidant, antibacterial, anti-inflammatory, and cytotoxic activities of leaves ofS. lycocarpum.

Stryphnodendron adstringens (Mart.) Coville, 1910 is a small tree, distributed widely throughout the Cerrado region of Brazil and named "barbatimão" by the Tupi-Guarani tribes, which presents astringent properties. Its ethnopharmacological uses comprise, among others, anti-inflammatory and wound healing action, and it is used in the treatment of diarrhea and gynecological problems. The phytotherapeutic use of 'barbatimão' is largely related to its tannin content, which is abundant in its bark. The main goal of the present study was to evaluate the cytotoxic, mutagenic, and genotoxic potential of the lyophilized solution of the stem bark of S. adstringens, using the Ames test, the SOS-Inductest and the SOS-Chromotest. S. adstringens presented cytotoxic activity in all tested systems, did not present mutagenic activity detectable by the Ames test and SOS-Chromotest, and showed some genotoxic effect on the SOS-Inductest. However, the metabolization of the extract by S9 fraction attenuated its genotoxic and cytotoxic activities.
