Abstract
Pistacia atlantica Desf. (Atlas Pistachio) is an Anacardiaceae tree traditionally used in Tunisia for the treatment of ophthalmic, stomatitis, and digestive tract diseases. In the present study, the Pistacia atlantica Desf. roots extract (PR) was phytochemically analyzed, for the first time, by LC-ESI-MS for phenolic and flavonoid contents, in vitro tested for its potential antioxidant activity based on the 2.2-diphenyl-1-picrylhydrazyl (DPPH) and the reduced power essays (FRAP), and in vivo tested for its ability to shield against ethanol-induced gastric ulcer in mice. The LC-ESI-MS analysis proved the identification of 12 compounds, including Quinic, Gallic, and Protocatechuic, as major phenolic acids and high levels of flavonoids, such as Catechin, Epicatechin, and Cirsiliol. PR also exhibited a mild in vitro antioxidant activity when compared with ascorbic acid. In vivo pretreatment of ethanol-ulcerated mice with PR doses 50 mg/kg and 100 mg/kg body weight (b.w) significantly reduced (P< .05) gastric lesions at a rate of 20.10% and a rate of 40.90%, respectively, when compared with 60.70% rate of sucralfate (50 mg/kg b.w) evidenced by a dose-dependent manner increase in the gastric mucosa enzymatic (SOD, CAT, GPx) antioxidant levels, the decline of the lipid peroxidation, and the preservation of normal gastric superficial epithelium. The underlying mechanism of PR antiulcerogenic activity could be due to a synergistic effect of phenolic acids and flavonoid contents which enhances the gastric antioxidant defense system.Abbreviations: BHT: butylated hydroxytoluene, b.w: body weight, CAT: catalase, DPPH:1-Diphenyl-2-picrylhydrazyl, DW: dry weight, EtOH: ethanol, FRAP: Ferric reducing antioxidant power, GAE: gallic acid equivalents, GPx: Glutathione peroxidase, QE: quercetin equivalents, LC-ESI-MS: Liquid chromatography-Electrospray Ionization-Tandem Mass Spectrometry, MDA: malondialdehyde, PR: Pistacia root, TBA: thiobarbituric acid reagent, TBARS: thiobarbituric acid reactive substances, TCA: trichloroacetic acid, SOD: Superoxide dismutase.

Abstract
This work focused on characterizing hydrophilic fractions of Clematis flammula (CFl). The data here clearly demonstrated that hydrolate fractions act as a free radical scavengers and inhibited proliferation of different cell lines in a time- and concentration-dependent manner, transwell, and with a significant cytotoxic effect. Treating cells with CFl had the effect of suppressing cell growth attenuated by ROS generation in colonic carcinoma. Moreover, CFl in HCT116 cells suppressed survival, proliferation, invasion, angiogenesis and metastasis in vitro by inhibiting gene expression. Following CFl treatment, caspases and PARP cleavage were detected. The up- and down-regulated genes obtained from the WBA of the effect of CFl showed that several biological processes were associated with apoptosis and induction of G1 cell cycle arrest. CFl synergizes the effect of TRAIL by down-regulating the expression of cell survival proteins involved in apoptosis compared to cells treated with CFl or TRAIL alone. Our findings showed that CFl sensitizes apoptosis in TRAIL-resistant cells by activating MAPKs, SP1, and CHOP, that induced DR5 expression. Overall, our data showed that CFl is a promising antitumor agent through kinases and transcription factor induction, both of which are required to activate TRAIL receptors. Colon inflammation induced by LPS was inhibited by CFl hydrolate.
