This study aimed to provide scientific evidence for predicting quality markers(Q-markers) of Elephantopus scaber by establishing UPLC fingerprint of E. scaber from different geographical origins and determining the content of 13 major components, as well as conducting in vitro anti-cancer activity investigation of the main components. The chromatographic column used was Waters CORTECS UPLC C_(18)(2.1 mm×150 mm, 1.6 μm), and the mobile phase consisted of acetonitrile and 0.1% formic acid solution(gradient elution). The column temperature was set at 30 ℃, and the flow rate was 0.2 mL·min~(-1). The injection volume was 1 μL, and the detection wavelength was 240 nm. The UPLC fingerprint of E. scaber was fitted using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine(2012 edition) to determine common peaks, evaluate similarity, identify and determine the content of major components. The CCK-8 assay was used to explore the inhibitory effect of the main components on the proliferation of lung cancer cells. The results showed that in the established UPLC fingerprint of E. scaber, 35 common peaks were identified. Thirteen major components, including neochlorogenic acid(peak 1), chlorogenic acid(peak 2), cryptochlorogenic acid(peak 3), caffeic acid(peak 4), schaftoside(peak 6), galuteolin(peak 9), isochlorogenic acid B(peak 10), isochlorogenic acid A(peak 12), isochlorogenic acid C(peak 18), deoxyelephantopin(peak 28), isodeoxyelephantopin(peak 29), isoscabertopin(peak 31), and scabertopin(peak 32) were identified and quantified, and a quantitative analysis method was established. The results of the in vitro anti-cancer activity study showed that deoxyelephantopin, isodeoxyelephantopin, isoscabertopin, and scabertopin in E. scaber exhibited inhibition rates of lung cancer cell proliferation exceeding 80% at a concentration of 10 μmol·L~(-1), higher than the positive drug paclitaxel. These results indicate that the fingerprint of E. scaber is highly characteristic, and the quantitative analysis method is accurate and stable, providing references for the research on quality standards of E. scaber. Four sesquiterpene lactones in E. scaber show significant anti-cancer activity and can serve as Q-markers for E. scaber.

Guaiane-type sesquiterpenoids are a class of terpenoids with [5,7] ring-fused system as the basic skeletal structure composed of three isoprene units, which are substituted by 4,10-dimethyl-7-isopropyl. According to the difference in functional groups and degree of polymerization, they can be divided into simple guaiane-type sesquiterpenoids, sesquiterpene lactones, sesquiterpene dimers, and sesquiterpene trimers. Natural guaiane-type sesquiterpenoids are widely distributed in plants, fungi, and marine organisms, especially in families such as Compositae, Zingiberaceae, Thymelaeaceae, Lamiaceae, and Alismataceae. Guaiane-type sesquiterpenoids have good antibacterial, anti-inflammatory, anticancer, and neuroprotective effects. In this paper, the novel guaiane-type sesquiterpenoids isolated and identified in recent 10 years(2013-2022) and their biological activities were reviewed in order to provide refe-rences for the research and development of guaiane-type sesquiterpenoids.

Xixiancao( Siegesbeckiae Herba) has the effect of treating ischemic stroke( IS),however,the mechanism has not been fully elucidated. In this study,combined with Lipinski's five principles and Veber oral bioavailability rules,68 chemical components of Xixiancao were obtained by database and literature search. Based on the reverse targeting,248 potential targets were obtained and mapped it to the ischemic stroke target set,47 potential targets for the treatment of ischemic stroke were obtained. Molecular docking technique was used to verify that the Xixiancao component has good binding activity to potential targets. GO enrichment analysis and pathway analysis were performed on potential targets using Clue GO. GO enrichment analysis showed that Xixiancao was mainly involved in life processes such as neuronal apoptosis,cholesterol storage and blood pressure regulation. Pathway analysis showed that Xixiancao may promote vascular repairing and regeneration by regulating the expression of ADAMTS1,FLT1 and KDR in VEGFA-VEGFR2 signaling pathway,activate cell survival signals and inhibit neuronal apoptosis by regulating the expression of CAMK2 AA,MDM2,MAPK1,MAPK3,CDK5 and MAPK10 in brain-derived neurotrophic factor signaling pathway and PI3 K-Akt signaling pathway. Lipid homeostasis and inflammation may also be regulated by Xixiancao through regulating the expression of ESR1,NR1 H3,PPARA,PPARG in the nuclear receptor signaling pathway. In addition,Xixiancao could also prevent platelet aggregation by regulating the expression of ITGA2 B,F2,F10,and ALB,and play an antithrombotic role. The results of this study indicate that Xixiancao plays an important role in the treatment of ischemic stroke mainly through anti-thrombosis,promoting angiogenesis,protecting neurons,anti-inflammatory and regulating blood pressure and lipids.

This study aims to investigate the PPARγ agonists isolated from the aqueous extract of Siegesbeckia pubescens( SPA) and their anti-inflammatory activities in vitro. The 293 T cells transfected transiently with PPARγ recombinant plasmid were used as a screening model to guide the isolation of PPARγ activitating components,and then PPARγ activities were measured by double luciferase reporter gene assay. The chemical structures were identified by chromatography or spectroscopic techniques. Furthermore,a UC inflammatory model in vitro was established on HT-29 cells by stimulating with TNF-α. The mRNA levels and secretion of proinflammatory cytokines on HT-29 cells,such as IL-1β,TNF-α,IL-8,were detected by RT-PCR and ELISA. The results showed that five diterpenoids were obtained from the fraction D_(50) with the strongest PPARγ activity among others in SPA,and determined as kirenol( 1),darutigenol( 2),enantiomeric-2-ketone-15,16,19-three hydroxypinomane-8( 14)-ene-19-O-β-D-glucoside( 3),darutoside( 4),enantiomeric-2-β,15,16,19-four hydroxypinomane-8( 14)-ene-19-O-β-D-glucoside( 5),respectively. All the compounds exhibited active effects on PPARγ in a concentration-dependent manner( P<0. 01). In addition,compound 1 significantly inhibited the expression of IL-1β mRNA and secretion of IL-8 on HT-29 cells inflammation model( P<0. 001); both compounds 2 and 3 effectively inhibited the expression of IL-1β,TNF-α,IL-8 mRNA and secretion of IL-8( P<0. 01 or P<0. 001),although at different extent; compound 4 significantly inhibited the expression of IL-1β and TNF-α mRNA( P<0. 01 or P<0. 001),while compound 5 inhibited the expression of IL-1β mRNA obviously( P<0. 001). In conclusion,the diterpenoids 1-5 isolated from S. pubescens have the PPARγ activation activities and potential effects of anti-UC in vitro.

Kudiezi injection has been used extensively in the treatment of cerebrovascular and cardiovascular diseases. However, its therapeutic effects and underlying mechanism of action are not fully understood. The aim of the present study was to clarify the protective mechanisms of Kudiezi injection on cerebral ischemic injury, using metabolomics methods. Middle cerebral artery occlusion (MCAO) was introduced in rats to build the cerebral ischemic damage. UHPLC-LTQ-Orbitrap-based analytical method was established for analysis of the metabolites. The raw mass data of all samples were normalized with Sieve 2.2 software and then introduced to orthogonal partial least squares discriminant analysis (OPLS-DA) model. Finally, 23 metabolites in plasma (15 were tentatively identified) were chosen as potential biomarkers, according to accurate mass measurements (< 5 ppm), MS/MS fragmentation patterns, and diagnostic product ions. Furthermore, on the basis of metabolic pathway analysis via metabolomics pathway analysis (MetPA), we first discovered that the protection mechanism in anti-ischemic cerebral reperfusion damage of Kudiezi injection was possibly related to the biosynthesis of phenylalanine, tyrosine, and tryptophan. The present study provided a useful approach for exploring the mechanism of ischemic stroke and evaluating the efficacy of Kudiezi injection or other traditional medicines.

Tripolinolate A (TLA) is recently identified as a new compound from a halophyte plant Tripolium vulgare and has been shown to have significant in vitro activity against the proliferation of colorectal cancer and glioma cells. This study was designed to further investigate the effects of TLA on the proliferation of human normal cells, and the apoptosis and cell cycle in colorectal cancer cells, and the growth of tumors in the colorectal cancer-bearing animals. The data obtained from this study demonstrated that: 1) TLA had much less cytotoxicity in the human normal cells than the colorectal cancer cells; 2) TLA remarkably induced apoptosis in the human colorectal cancer cells and blocked cell cycle at G/M phase, and 3) TLA had significant anti-colorectal cancer activity in the tumor-bearing animals.
