Xerolekia speciosissima (L.) Anderb., a rare plant from the north of Italy, is a member of the Inuleae-Inulinae subtribe of the Asteraceae. Despite its close taxonomic relationship with many species possessing medicinal properties, the chemical composition of the plant has remained unknown until now. A hydroalcoholic extract from the aerial parts of X. speciosissima was analyzed by HPLC-DAD-MSn, revealing the presence of caffeic acid derivatives and flavonoids. In all, 19 compounds, including commonly found chlorogenic acids and less frequently occurring butyryl and methylbutyryl conjugates of dicaffeoylquinic and tricaffeoylhexaric acids, plus two flavonoids, were tentatively identified. Chromatographic separation of a hydroalcoholic extract from the capitula of the plant led to the isolation of (+)-dehydrodiconiferyl alcohol 4-O-β-glucopyranoside, quercimeritrin, astragalin, isoquercitrin, 6-hydroxykaempferol-7-O-β-glucoside, quercetagitrin, methyl caffeate, caffeic acid, protocatechuic acid, chlorogenic acid and 1,5-dicaffeoylquinic acid. Composition of a nonpolar extract from the aerial parts of the plant was analyzed by chromatographic methods supported with 1H-NMR spectroscopy. The analysis revealed the presence of loliolide, reynosin, samtamarine, 2,3-dihydroaromaticin, 2-deoxy-4-epi-pulchellin and thymol derivatives as terpenoid constituents of the plant. One of the latter compounds—7,10-diisobutyryloxy-8,9-epoxythymyl isobutyrate—at concentrations 0.5, 1.0 and 2.5 μM, significantly reduced IL-8, IL-1β and CCL2 excretion by LPS-stimulated human neutrophils.

Abstract Six hydroxycinnamic acids : caffeic acid, chlorogenic acid, 3,5-O-dicaffeoylquinic acid 2-O-caffeoyltartaric acid (caftaric acid) and 2,3-O-dicaffeoyltartaric acid (chicoric acid) have been isolated from Lapsana communis L. subsp. communis aerial parts. Among flavonoids, only isoquercitrin, luteolin and luteolin-7-O-β-glucuronide were identified. Except for chlorogenic acid, these com­ pounds represent the first report in Lapsana communis. Chicoric acid is the major phenylpropanoic constituent in this plant.

Carpesium divaricatum Sieb. & Zucc. has a long history of use as both a medicinal and a food plant. However, except for terpenoids, its chemical constituents have remained poorly investigated. The composition of hydroalcoholic extract from aerial parts of C. divaricatum was analyzed by HPLC-DAD-MSn, revealing the presence of numerous caffeic acid derivatives that were formerly unknown constituents of the plant. In all, 17 compounds, including commonly found chlorogenic acids and rarely occurring butyryl and methylbutyryl tricaffeoylhexaric acids, were tentatively identified. Fractionation of lipophilic extract from cultivated shoots led to the isolation of 12-oxo-phytodienoic acid (12-OPDA), which is a newly identified constituent of the plant. The compound, at concentrations of 0.5, 1.0, and 2.5 μM, significantly reduced IL-8, IL-1β, TNFα, and CCL2 excretion by lipopolysaccharide (LPS)-stimulated human neutrophils. Reactive oxygen species (ROS) production induced by f-MLP was also significantly diminished in the neutrophils pretreated by 12-OPDA. The newly identified constituents of the plant seem to be partly responsible for its pharmacological activity and elevate the value of C. divaricatum as a potential functional food.

Background: Stachys lavandulifolia Vahl is an herbaceous perennial plant which its flowering aerial parts are used traditionally as gastrotonic, spasmolytic, sedative and for the treatment of gastrointestinal disorders. In the present study the aerial parts of this medicinal plant was investigated for its flavonoid glycosides content. Methods: n-butanol fraction derived from hydroalcoholic extract of S. lavandulifolia was subjected to phytochemical analysis using chromatography on Sephadex LH-20 and RP-18 silica gel columns. The structures of isolated compounds were identified using 1H-NMR, 13C-NMR and UV spectral analysis. Results: Four flavone glycosides, chrysoeriol-7-O-β-D-glucopyranoside (1), apigenin-7-O-(6″-O-acetyl)-β-D-glucopyranoside (2), luteolin-7-O-β-D-glucopyranoside (3), apigenin-7-O-β-D-glucopyranoside (4), along with apigenin (5) and chlorogenic acid (6) were isolated from S. lavandulifolia aerial parts. Conclusion: Identification of these phenolic compounds with some known biological activities in S. lavandulifolia explains some medicinal properties reported for this species and make scientific rationale for its traditional uses.

Objective: The study evaluated the hypolipidemic and anti-inflammatory potential of the hydroalcoholic extract of P. Aculeata (HEPa/EtOAC) in Wistar rats fed with Westernized diet. Methods: The experiment was approved by the Ethics Committee (Federal University of Pernambuco-23076.027165 / 2010-21). The hydroalcoholic extract (HEPa/EtOAc) was obtained from the aerial parts of P. Aculeata and portioned by acetate/ethanol in different concentrations. 36 male Wistar rats were initially divided into two groups: Control (C, n = 6), fed a commercial diet (26g / 100g of protein; 63g / 100g of carbohydrates; 11g / 100g of lipids) and Westernized (W; n = 30) – fed an experimental diet (15g / 100g of protein; 51g / 100g of carbohydrates; 34 g/100g of lipids) receving water ad libitum. After 4 months of diet, W group was arbitrarily redistributed into six subgroups according to water supplementation, or different extracts concentrations: (n = 6 animals/group): W- distilled water (1mL/kg; po); WG – genfibrozil (140 mg/kg; p.o.); W35- 35 mg/kg; W70 – 70 mg /kg; p.o. and W140- 140 mg/kg; p.o for 30 days. The lipid profile and pro-inflammatory cytokines were analyzed. Results: The westernized diet caused dyslipidemia and the treatment with HEPa-EtOAc (140mg / kg), promoted a significant reduction in the concentration of pro-inflammatory cytokines, in total cholesterol, in the LDLc and serum triglycerides. Conclusion: The reduction of dyslipidemia and pro-inflammatory cytokines from the of P. Aculeata extract corroborate the ethnopharmacological potential of the plant, already used by the population for hypoglycemic purposes.

Two new eremophilenolides, 6β8β10β-trihydroxyeremophil-7(11)-en-12,8-olide (1) and 3βacetoxy-8α-hydroxy-6β-methoxyeremophila-7(11),9-dien-12,8-olide (2) along with twenty-nine other compounds were obtained from the methanolic extracts of the aerial parts and rhizomes of Farfugium japonicum (L.) Kitam. v ar. formosanum (Hayata) Kitam. (Compositae = Asteraceae). The structures of the isolated compounds were characterized and identified by spectral techniques. Compounds 5, 6, 10, 12-24, 29, and 30, were reported for the first time from this genus. Cytotoxicity and anti-inflammatory activity of the isolated compounds were evaluated. Compounds 3 and 16 possessed moderate cytotoxicity against human breast cancer cell line (MCF 7). Compounds 3, 16, 25 and 26 exhibited moderate cytotoxicity against hepatoma cells (Hep G2 and Hep 3B). With respect to the anti-inflammatory activity, compounds 15 and 16 (each 10 μg/mL) inhibited superoxide anion generation by human neutrophils in response to fMLP/CB by 92.0% and 87.3%, respectively.

Objective: The aim of this study was to evaluate anti-inflammatory activity and cytotoxicity in vitro of hydroalcoholic extract of Bidens andicola.Methods: B. andicola hydroalcoholic extract was obtained from aerial parts of B. andicola, following a standardized methodology. Briefly, aerial parts of B. andicola were extracted with ethanol 70% v/v and defatted with n-hexane, hydroalcoholic fraction was concentrated under controlled conditions in a rotary evaporator, and finally the residue was freeze-drying to obtain the hydroalcoholic extract of B. andicola. Anti-inflammatory activity and cytotoxicity assays were carried out using in vitro isolated neutrophils model using stable water-soluble tetrazolium salts.Results and Conclusions: The in vitro anti-inflammatory assay on isolated neutrophils demonstrated that the hydroalcoholic extract showed antiinflammatoryactivity compared to aspirin, with inflammatory inhibition percent values of 80.138±0.729 to hydroalcoholic extract of B. andicola and 82.117±0.762 to aspirin, each tested in five replicates at the concentration of 200 ppm of hydroalcoholic extract or reference.
