Abstract
INTRODUCTION Arenaria kansuensis Maxim. (AKM) is one of the most valued medicinal and edible herbs widely used in Qinghai-Tibet Plateau and there is also a large number of AKM bioactive constituents for health benefits of human beings. However, few works have referred to phytochemical content, fingerprint analysis and quality control of AKM. Therefore, the establishment of validated analytical methods is urgently needed for fingerprint comparison and quantitative analysis of AKM multicomponent. OBJECTIVES To determine quantitatively and compare the phytochemical constituents of AKM located at different areas. METHODOLOGY The chemical constituents in AKM samples were separated, identified, and quantified by high-performance liquid chromatography (HPLC) with a diode array detector. The discrimination and separation models for the chemical constituents were developed by chemometric analysis. RESULTS The flavones and β-carboline alkaloids were rich in AKM herbs, and the overall pattern of phytochemical profiles was the same, while the significant differences were detected in the total flavonoids, total β-carboline alkaloids and individual contents, especially the predominant compounds such as tricin and arenarine B. This demonstrated that ecogeographical origin gave an important impact on phytochemical compositions which could be considered as reliable parameters for classifying the AKM resources. Moreover, the contents of AKM constituents were higher in July and/or August than other months of the year, and there were no significant differences in the main phytochemical contents between cultivated and wild AKM herbs. CONCLUSION This study could provide credible data and method for geographical origin trace, comprehensive evaluation and further utilization of AKM resources.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The plant Arenaria kansuensis is used in traditional medicine to treat lung inflammation for a long time. However, the anti-pulmonary fibrosis effect and its corresponding bioactive constituents of this plant have not been studied extensively. AIM OF THE STUDY The purpose of this study was to investigate the anti-pulmonary fibrosis effect and its corresponding bioactive constituents of A. kansuensis and its possible mechanism. MATERIALS AND METHODS In vivo experiment, the anti-pulmonary fibrosis effects of the fraction (Part1) enriched from ethyl acetate extracts of the whole plant A. kansuensis were evaluated through bleomycin (BLM)-induced pulmonary fibrosis mice (five groups, n = 10) daily at doses of 50, 100 and 150 mg/kg for 15 days. In vitro experiment, the anti-inflammation and reversed epithelial-mesenchymal transition (EMT) effect of 12 β-carboline alkaloids isolated from Part1 were evaluated through lipopolysaccharide (LPS)-induced RAW264.7 inflammatory cell model and TGF-β1 induced A549 cell model. RESULTS In this study, a fraction named Part1 extracted from Arenaria kansuensis presented strong anti-pulmonary fibrosis effect at the dose of 150 mg/kg. Vivo experiments showed that the survival rate and body weight of mice significantly increased after Part1 treatment. Part1 could significantly inhibit the initial of inflammation, deposition of collagen and expression of TGF-β1 and α-SMA, moreover, the expression of E-cadherin was significantly elevated after administration of Part1. All the cure effects of Part1 were in dose dependent manner. A total of 12 β-carboline alkaloids were identified in Part1 and they all showed suppressive effect on inflammatory cytokines including MCP-1, TNF-α, IL-6 and IL-1β through inhibition of NF-kb/p65 phosphorylation, and that epithelial-mesenchymal transition (EMT) process was reversed by different compounds in different levels. The expression of indicators of EMT including α-SMA, vimentin and E-cadherin was significantly improved after given different β-carboline alkaloids. CONCLUSIONS This study showed that antifibrogenic effect of β-carboline alkaloids was due to inhibiting the initial of inflammation through NF-kb/p65 pathway and reversing the process of EMT.

Abstract
Flavonol compounds of three Mediterranean plants from the Algerian Atlas used traditionally in Arab folk medicine, Arenaria serpyllifolia, Rhamnus alaternus and Thapsia garganica, were found to inhibit the enzymatic activities of both rat intestine and purified porcine liver carboxylesterase in a concentration-dependent manner. Results indicate that the flavonol compounds from the aerial part of these plants lead to the inactivation of the CE pI = 5.1 with Ki of micromolar range. These results encourage us to perform further biological investigation.
