In this study, we evaluated and compared the chemical composition, the antioxidant, anti-inflammatory, and anti-proliferative effects of four methanol extracts (R1–R4), of Salvia rosmarinus Spenn. in two different sites of Southern Italy obtained by maceration or ultrasound-assisted extraction. Extracts of S. rosmarinus collected on the Ionian coast are indicated with the abbreviations R1 (maceration) and R2 (ultrasound-assisted extraction). Extracts of S. rosmarinus collected on the Tyrrhenian coast are indicated with the abbreviations R3 (maceration) and R4 (ultrasound-assisted extraction). The chemical composition was analyzed using High Pressure liquid chromatography–Diod-Array detection–Electrospray ionization–Quadrupole–Mass Spectroscopy (HPLC-DAD-ESI-Q-MS). The antioxidant activity was analyzed by 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) 2,2-diphenyl-1-picrylhydrazyl (DPPH), β-carotene bleaching, and Ferric Reducing Antioxidant Power (FRAP) assays. Antioxidant features were also assessed in lipopolysaccharide (LPS)-stimulated RAW-264.7 murine macrophages, evaluating Reactive Oxygen Species (ROS) production; in the same experimental model, the anti-inflammatory activity of the extracts was investigated. Interestingly, all extracts displayed antioxidant and anti-inflammatory properties. They exhibited significative nitrite production inhibitory activity, whith IC50 values ranging from 3.46 to 5.53 µg/mL, without impairing cell viability. The anti-inflammatory activity was also investigated by Western Blotting and immunofluorescence assay, highlighting the R3 and R4 extracts ability to reduce NF-κB translocation, as well as to disrupt the MAPKs signaling pathway. Extracts exhibited both potential anti-proliferative activity on breast cancer cells, inducing apoptosis, without affecting non-tumorigenic cells, and the ability to inhibit MDA-MB-231 cells’ motility. Finally, the rosemary extracts treatment significantly reduced the power of conditioned media, from MCF-7 or MDA-MB-231 cells to induce nitrite production on RAW 264.7 cells, confirming their promising anti-inflammatory activity.

The present study is the first investigation of the chemical composition, antioxidant, antimicrobial and anti-inflammatory activities of the stem and leaf essential oils from Piper flaviflorum C.DC (SEOP and LEOP), a plant that has been consumed as a wild vegetable, and used as medicine, and spice by the ethnic groups in Xishuangbanna, SW China. Analyzed by GC-MS, 42 and 30 components were identified representing 90.1% and 95.3% of the SEOP and LEOP, with (E)-nerolidol (16.7% and 40.5%), β-caryophyllene (26.6% and 14.6%) and elixene (5.3% and 12.3%) as their main constituents, respectively. Our results indicate that SEOP and LEOP have good anti-inflammatory activity by significantly inhibiting NO production induced by LPS in RAW 264.7 cells at 0.04± without effect on cell viability, and negligible antioxidant activity in both ABTS and FRAP assays. Moreover, the LEOP showed comparable activity with the positive control (tigecycline) against Aspergillus fumigatus, with MIC and MBC values ranging from 256 to 1024 μg/mL. The anti-inflammatory activity in LPS-induced RAW 264.7 cells is worthy of further investigation to discover the possible mechanisms of the NO production inhibition effect of these essential oils.

Angiopteris helferiana C.Presl is a gigantic fleshy-type fern, belonging to Marattiaceae family. In previous study, we reported the potent anti-adipogenic and anti-inflammatory activities of ethylacetate (EtOAc) and n-butanol (BuOH) fractions of methanol extract of rhizomes of A. helferiana. In continuation, in this study, we report the isolation, characterization, and bioactivity analysis of principle bioactive compounds in these fractions. (−)-epi-Osmundalactone (1) and angiopteroside (2) were isolated from EtOAc and BuOH fractions, respectively. The structures of these compounds were established on the basis of NMR spectroscopic data. The quantification study using UPLC revealed the contents of compounds 1 and 2 in the dried rhizome to be 1.54% and 3.2%, respectively. These compounds were evaluated for their anti-adipogenic and anti-inflammatory activities using 3T3-L1 and RAW 264.7 cells, respectively. Compound 1 (2.5 µg/mL) and 2 (20 µg/mL) inhibited the lipid production by 35% and 25%, respectively. Regarding the anti-inflammatory activity, compound 1 (5 µg/mL) inhibited the nitrite production by nearly 82%. In conclusion, the presence of potent anti-adipogenic and anti-inflammatory compounds in A. helferiana indicate its potential role in the use of herb-based treatment for obesity and other related diseases.

Object. Ultrasound-assisted extraction of total flavonoids from corn silk and their antioxidant activities were studied.Methods. Response surface methodology was adopted to optimize the extraction conditions and antioxidant activities of the extracted total flavonoids were detected through ferric reducing antioxidant power (FRAP) assay.Results. Through a three-level, three-variable Box-Behnken design of response surface methodology (RSM) adopting yield as response, the optimal conditions were determined as follows: ultrasonic power 500 W, extraction time 20 min, material solvent ratio 1 : 20, and ethanol concentration 30%. Under the optimum conditions, the extraction yield of total flavonoids was 1.13%. FRAP value of total flavonoids extracted from corn silk was 467.59 μmol/L.Conclusion. The total flavonoids of corn silk could be developed as food natural antioxidant reagents.
