Abstract
Purpose Type 2 diabetes mellitus (T2DM) is associated with reduced insulin uptake and glucose metabolic capacity. Potentilla discolor Bunge (PDB) has been used to treat T2DM; however, the fundamental biological mechanisms remain unclear. This study aimed to understand the active ingredients, potential targets, and underlying mechanisms through which PDB treats T2DM. Methods Components and action targets were predicted using network pharmacology and molecular docking analyses. PDB extracts were prepared and validated through pharmacological intervention in a Cg>InRK1409A diabetes Drosophila model. Network pharmacology and molecular docking analyses were used to identify the key components and core targets of PDB in the treatment of T2DM, which were subsequently verified in animal experiments. Results Network pharmacology analysis revealed five effective compounds made up of 107 T2DM-related therapeutic targets and seven protein-protein interaction network core molecules. Molecular docking results showed that quercetin has a strong preference for interleukin-1 beta (IL1B), IL6, RAC-alpha serine/threonine-protein kinase 1 (AKT1), and cellular tumor antigen p53; kaempferol exhibited superior binding to tumor necrosis factor and AKT1; β-sitosterol demonstrated pronounced binding to Caspase-3 (CASP3). High-performance liquid chromatography data quantified quercetin, kaempferol, and β-sitosterol at proportions of 0.030%, 0.025%, and 0.076%, respectively. The animal experiments revealed that PDB had no effect on the development, viability, or fertility of Drosophila and it ameliorated glycolipid metabolism disorders in the diabetes Cg>InRK1409A fly. Furthermore, PDB improved the body size and weight of Drosophila, suggesting its potential to alleviate insulin resistance. Moreover, PDB improved Akt phosphorylation and suppressed CASP3 activity to improve insulin resistance in Drosophila with T2DM. Conclusion Our findings suggest that PDB ameliorates diabetes metabolism disorders in the fly model by enhancing Akt activity and suppressing CASP3 expression. This will facilitate the development of key drug targets and a potential therapeutic strategy for the clinical treatment of T2DM and related metabolic diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The polyherbal mixture made of Centaurium erythraea aerial parts and Cichorium intybus roots and Potentilla erecta rhizomes has been used for centuries to treat both the primary and secondary complications of diabetes. AIM OF THE STUDY As a continuation of our search for the most effective herbal mixture used as an ethnopharmacological remedy for diabetes, this study aimed to compare the in vitro biological activities of this polyherbal mixture and its individual ingredients, and, most importantly, to validate the ethnopharmacological value of the herbal mixture through evaluation of its phytochemical composition, its potential in vivo toxicity and its effect on diabetes complications. MATERIALS AND METHODS Phytochemical analysis was performed using HPLC-UV. Antioxidant activity was estimated via the DPPH test. Potential cytotoxicity/anticytotoxicity was assessed using an in vitro RBCs antihemolytic assay and an in vivo sub-chronic oral toxicity method. Antidiabetic activity was evaluated using an in vitro α-amylase inhibition assay and in vivo using a chemically induced diabetic rat model. RESULTS The HPLC-UV analysis revealed the presence of p-hydroxybenzoic acid, p-hydroxybenzoic acid derivative, catechin, five catechin derivatives, epicatechin, isoquercetin, hyperoside, rutin, four quercetin derivatives, caffeic acid, and four caffeic acid derivatives in the polyherbal mixture decoction. Treatment with the decoction has shown no toxic effects. The antioxidant and cytoprotective activities of the polyherbal mixture were higher than the reference's ones. Its antidiabetic activity was high in both in vitro and in vivo studies. Fourteen days of treatment with the decoction (15 g/kg) completely normalized blood glucose levels of diabetic animals, while treatments with insulin and glimepiride only slightly lowered glycemic values. In addition, lipid status of treated animals as well as levels of serum AST, ALT, ALP, creatinine, urea and MDA were completely normalized. In addition, the polyherbal mixture completely restored the histopathological changes of the liver, kidneys and all four Cornu ammonis regions of the hippocampus. CONCLUSIONS The polyherbal mixture was effective in the prevention of both primary and secondary diabetic complications such as hyperlipidemia, increased lipid peroxidation, non-alcoholic fatty liver disease, nephropathy and neurodegeneration.

Abstract
Potentilla kleiniana Wight et Arn(PK, 'Wu Pi Feng' in Chinese) was recorded as Miao ethnic medicine for treatment of fever, cough, ulcer, and erysipelas for thousands years. This study aimed to evaluate the antiviral activity of four PK extracts and seven compounds by using HIV-1 protease (HIV-1 PR). In addition, Ultra-High Performance Liquid Chromatography and High Resolution Mass Spectrometry (UPLC-HRMS) was employed to identify the bioactive components. The toxicity assessment of the extracts was done before antiviral screening using a highly specific human aspartyl protease, renin protease by fluorimetric method. As a result, seven compounds and four extracts of PK inhibited HIV-1 PR with IC50 range from 0.009 to 0.36 mg/mL, and did not appreciably inhibit the general human protease renin. This study first demonstrated that four PK extracts, ellagic acid and ursolic acid potent inhibit HIV-1 protease, could be used as an efficacious drug candidate to treat SARS-CoV-2 infection.

Abstract
Stroke is the most common cause of death among neurological diseases. The protective effects of Potentilla reptans L. include antioxidative, anti-inflammatory, and antiapoptotic effects. In this study, the brain protection and beta-amyloid effects of P. reptans root extract were investigated in the rat brain ischemia/reperfusion (IR) model. Forty male Wistar rats were randomly divided into five groups (n = 8), including IR, sham, and three groups receiving P. reptans with concentrations of 0.025, 0.05, and 0.1 (g/kg/b.w.), which were injected daily for 7 days. For the IR model, the common carotid artery was occluded bilaterally for 8 min. All injections were intraperitoneal (IP). The shuttle box test was used to measure passive avoidance memory. Then the brain tissue was extracted for the histological examination of neuron counts and β-amyloid plaques using a morphometric technique, and finally, Statistical Package for the Social Sciences software was used for statistical analysis of the data. Pretreatment with P. reptans improved memory impairment. Also, by examining the tissues of the CA1, CA3, and dentate gyrus areas of the hippocampus, it was observed that the number of plaques in the groups receiving P. reptans extract was reduced compared to the IR group, especially at the concentration of 0.05 g/kg/b.w. Also, P. reptans improved the number of neurons at all concentrations, in which the concentration of 0.05 g/kg/b.w. showed more effective therapeutic results. Taken together, we found that P. reptans root extract has beneficial effects on memory impairment, neuronal loss, and β-amyloid accumulation.

Abstract
Air pollution causes various airway diseases. However, many commonly used treatments can have high risks of side effects or are costly. To examine the anti-inflammatory properties of Inula japonica Thunb. and Potentilla chinensis Ser., a mouse model was generated via inhalation of both particulate matter 10 and diesel particulate matter, and 30% ethanol extracts of either I. japonica (IJ) or P. chinensis (PC) and a mixture of both ethanol extracts (IP) were orally administered to BALB/c mice for 12 days. IJ, PC, and IP inhibited immune cell numbers and their regulation in both the bronchoalveolar lavage fluid (BALF) and lungs. These agents suppressed the levels of interleukin (IL)-1α, IL-17, tumor necrosis factor (TNF)-α, C-X-C motif chemokine ligand (CXCL)-1, and CXCL-2 in BALF, and also inhibited F4/80 and IL-1 receptor-associated kinase (IRAK)-1 in lungs. They reduced the gene expression of TNF-α, CXCL-1, inducible NOS, COX-2, Mucin 5AC, and transient receptor potential cation channel subfamily V member 1 in lungs. These extracts also reduced histopathological changes and inflammatory progression, manifested as decreased cell infiltration, collagen deposition, and respiratory epithelial cell thickness. I. japonica and P. chinensis show potential for development as pharmaceuticals that suppress inflammatory progression and alleviate airway inflammation diseases caused by air pollutants.

Abstract
BACKGROUND Glioblastoma multiforme (GBM) is the most aggressive brain tumor that is common among adults. This aggression is due to increased invasion, migration, proliferation, angiogenesis, and decreased apoptosis. Plant-based compounds have a high potential to be used as an anticancer agent due to their various mechanisms and less undesirable side effects. Potentilla fulgens is a medicinal plant, and methanolic root extract of P. fulgens (PRE) has anti-inflammatory and anticancer properties. OBJECTIVE In this study, we aimed to investigate antiproliferative effect of PRE on U118 and T98G glioblastoma cancer cells and to reveal which molecular signaling pathways regulate this mechanism of action. MATERIALS AND METHODS The effect of PRE on cell viability of GBM cells was investigated by MTT assay. Involvement of PRE with cell growth and survival signaling pathways, phosphatidylinositol 3-kinase (PI3K)/Akt/mTOR and c-Src/signal transducer and activator of transcription 3 (STAT3), was examined using Western Blot. RESULTS PRE reduced cell viability of GBM and human dermal fibroblast (HDF) cells in a dose-and time-independent manner. PI3K expression/phosphorylation level remained unchanged in both GBM and HDF cells after PRE treatment, but Akt/mTOR signaling pathway was downregulated in PRE-treated cells. PRE treatment did not affect c-Src expression/phosphorylation level in GBM cells; however, expression of c-Src was suppressed in HDF cells. Similar results were observed for STAT3 expression and phosphorylation status. CONCLUSION PRE has the ability to suppress cell viability in GBM cells, by targeting the Akt/mTOR signaling pathway.

Abstract
The use of face masks during the COVID-19 pandemic resulted in significant societal changes, particularly for individuals with sensitive skin. To address this issue, the researchers explored traditional medicine and identified Potentilla anserina extract as a potential solution due to its anti-inflammatory and moisturizing effects. This research investigated how this extract influences skin hydration, barrier function, and itching. The findings revealed that the extract had a hydrating effect by elevating Aquaporin-3 (AQP3) expression. Additionally, the study demonstrated that the extract improved skin barrier function, with Filaggrin (FLG) expression being approximately three times higher (p < 0.001) in the Potentilla-anserina-extract-treated group compared to the control group and the genes associated with itching being reduced. In this process, we researched and developed HPβCD (hydroxypropyl-β-cyclodextrin)-Liposome containing Potentilla anserina extract, gradually and sustainably releasing the active components of the Potentilla anserina extract. During four weeks of clinical trials involving individuals wearing masks for over 6 h a day, a moisturizer containing Potentilla anserina extract demonstrated a notable reduction in skin redness. Hemoglobin values (A.U.), which serve as indicators of skin redness, showed decreases of 5.06% and 6.74% in the test area inside the mask after 2 and 4 weeks, respectively, compared to the baseline measurements. Additionally, the moisturizer containing Potentilla anserina extract notably decreased Trans Epidermal Water Loss (TEWL), with reductions of 5.23% and 9.13% observed in the test area inside the mask after 2 and 4 weeks, respectively. The moisturizer, especially in the test area treated with the extract-containing moisturizer, significantly enhanced skin hydration compared to the control group. The Corneometer values (A.U) exhibited notable increases of 11.51% and 15.14% in the test area inside the mask after 2 and 4 weeks, respectively. These discoveries emphasize the potential of Potentilla anserina extract and its utility in tackling skin issues caused by mask wearing, including enhancing moisture, fortifying the skin's barrier, and alleviating itching. These results indicate that moisturizers incorporating specific ingredients provide greater benefits compared to conventional moisturizers.

Abstract
Here, we present a protocol for the complete stereoselective synthesis of a molecular 51 knot. Enantiopure chiral ligands serve as the starting point, while Zn(OTf)2 acts as the template, facilitating the quantitative formation of pentameric circular helicates with 100% d.e. A subsequent sequence of ring-closing metathesis and demetalation steps transforms the structure into a fully organic 51 knot. This protocol expands the scope of strategies employed for chiral knot preparation and paves the way for more complex molecular topologies. For complete details on the use and execution of this protocol, please refer to Zhang et al.1.

Abstract
Despite the common use of Potentilla L. species (Rosaceae) as herbal medicines, a number of species still remain unexplored. Thus, the present study is a continuation of a study evaluating the phytochemical and biological profiles of aqueous acetone extracts from selected Potentilla species. Altogether, 10 aqueous acetone extracts were obtained from the aerial parts of P. aurea (PAU7), P. erecta (PER7), P. hyparctica (PHY7), P. megalantha (PME7), P. nepalensis (PNE7), P. pensylvanica (PPE7), P. pulcherrima (PPU7), P. rigoi (PRI7), and P. thuringiaca (PTH7), leaves of P. fruticosa (PFR7), as well as from the underground parts of P. alba (PAL7r) and P. erecta (PER7r). The phytochemical evaluation consisted of selected colourimetric methods, including total phenolic (TPC), tannin (TTC), proanthocyanidin (TPrC), phenolic acid (TPAC), and flavonoid (TFC) contents, as well as determination of the qualitative secondary metabolite composition by the employment of LC-HRMS (liquid chromatography-high-resolution mass spectrometry) analysis. The biological assessment included an evaluation of the cytotoxicity and antiproliferative properties of the extracts against human colon epithelial cell line CCD841 CoN and human colon adenocarcinoma cell line LS180. The highest TPC, TTC, and TPAC were found in PER7r (326.28 and 269.79 mg gallic acid equivalents (GAE)/g extract and 263.54 mg caffeic acid equivalents (CAE)/g extract, respectively). The highest TPrC was found in PAL7r (72.63 mg catechin equivalents (CE)/g extract), and the highest TFC was found in PHY7 (113.29 mg rutin equivalents (RE)/g extract). The LC-HRMS analysis showed the presence of a total of 198 compounds, including agrimoniin, pedunculagin, astragalin, ellagic acid, and tiliroside. An examination of the anticancer properties revealed the highest decrease in colon cancer cell viability in response to PAL7r (IC50 = 82 µg/mL), while the strongest antiproliferative effect was observed in LS180 treated with PFR7 (IC50 = 50 µg/mL) and PAL7r (IC50 = 52 µg/mL). An LDH (lactate dehydrogenase) assay revealed that most of the extracts were not cytotoxic against colon epithelial cells. At the same time, the tested extracts for the whole range of concentrations damaged the membranes of colon cancer cells. The highest cytotoxicity was observed for PAL7r, which in concentrations from 25 to 250 µg/mL increased LDH levels by 145.7% and 479.0%, respectively. The previously and currently obtained results indicated that some aqueous acetone extracts from Potentilla species have anticancer potential and thus encourage further studies in order to develop a new efficient and safe therapeutic strategy for people who have been threatened by or suffered from colon cancer.

Abstract
Potentilla alba is a valuable medicinal plant that has been highly praised even before its first appearance in herbal books; however, it has now been forgotten in Western Europe. Currently, this species is used in Eastern Europe as a remedy to treat dysentery and various thyroid gland dysfunctions. The present review summarizes the advances in the phytochemical, pharmacological, and toxicological research related to this plant species. Clinical trials that have been conducted to date support its traditional use for treating thyroid disorders, although its exact mechanism of action, bioavailability, and pharmacokinetics data are missing.

Abstract
OBJECTIVE The goal of this paper is to investigate the use of Potentilla bifurca in the treatment of type 2 diabetes. MATERIALS AND METHODS We analyzed the improvement effect of 3T3-L1 adipocytes under insulin resistance (IR) with the compounds of Potentilla bifurca. RESULTS The Potentilla bifurca can significantly improve the glycolipid metabolism disorder in 3T3-L1 adipocytes (the effect of MC compounds is very significant). It can improve insulin resistance by enhancing the glucose uptake of 3T3-L1 adipocytes, decreasing IL-6 content, and regulating the content of p-Akt/Akt, IKKβ, and p-NF-κBp65/NF-κBp65 in the IRS/PI3K/Akt signaling pathway. CONCLUSIONS Studies have shown that Potentilla bifurca has the ability to regulate glucolipid metabolism and can be used in the treatment of type 2 diabetes.

Abstract
A series of natural deep eutectic solvents (NADESs) were prepared with choline chloride, betaine, and a variety of natural organic acids in order to find new environmentally-friendly green solvents to replace the traditional solvents. The NADESs were employed to extract flavonoids from Potentilla fruticosa L. (PFL) with the help of ultrasound. The eutectic solvent diluted with an appropriate amount of water improved the extraction ability of flavonoids due to the decrease of solution viscosity. The microstructure of the raw sample and the samples subjected to ultrasonic bath in different solutions were observed using scanning electron microscope (SEM) to determine the role of the NADESs in the extraction process. The DPPH method and glucose consumption method were used to study the antioxidant and hypoglycemic ability of flavonoid compounds in PFL. Single factor method and response surface methodology (RSM) were designed to analyze the effects of three extraction parameters, including solvent/solid ratio, ultrasonic power, and extraction time, on the extraction yield, antioxidant capacity, and hypoglycemic capacity, and the corresponding second-order polynomial prediction models were established. The optimal extraction conditions for the maximum extraction yield, antioxidant capacity, and hypoglycemic capacity were predicted by RSM, and the reliability of RSM simulation results was verified by a one-off experiment.

Abstract
Excessive lipid accumulation in white adipose tissue (WAT) is the major cause of obesity. Herein, we investigated the anti-obesity effect and molecular mechanism of a botanical mixture of 30% EtOH extract from the leaves of Inula japonica and Potentilla chinensis (EEIP) in 3T3-L1 preadipocytes and high-fat diet (HFD)-fed obese mice. In vitro, EEIP prevented lipid accumulation by downregulating the expression of lipogenesis-related transcription factors such as CCAAT/enhancer binding protein (C/EBP)α, peroxisome proliferator-activated receptor (PPAR)γ, and sterol regulatory element binding protein (SREBP)-1 via AMP-activated protein kinase (AMPK) activation and G0/G1 cell cycle arrest by regulating the Akt-mTOR pathways without inducing cytotoxicity. In vivo, EEIP significantly reduced body weight gain and body fat mass in the group administered concurrently with HFD (pre-) or administered during the maintenance of HFD (post-) including subcutaneous, gonadal, renal, and mesenteric fats, and improved blood lipid profiles and metabolic hormones. EEIP pre-administration also alleviated WAT hypertrophy and liver lipid accumulation by reducing C/EBPα, PPARγ, and SREBP-1 expression via AMPK activation. In the brown adipose tissue, EEIP pre-administration upregulated the expression of thermogenic factors. Furthermore, EEIP improved the HFD-induced altered gut microbiota in mice. Taken together, our data indicated that EEIP improves HFD-induced obesity through adipogenesis inhibition in the WAT and liver and is a promising dietary natural material for improving obesity.

Abstract
In this study, supercritical fluid extraction (SFE), ultrasonic-assisted extraction (UAE), and microwave-assisted extraction (MAE) were applied to explore the most suitable extraction method for fatty acids of Potentilla anseris L. from 12 different producing areas of the Qinghai-Tibetan Plateau. Meanwhile, the important experimental parameters that influence the extraction process were investigated and optimized via a Box-Behnken design (BBD) for response surface methodology (RSM). Under optimal extraction conditions, 16 fatty acids of Potentilla anserina L. were analyzed via high-performance liquid chromatography (HPLC) with fluorescence detection, using 2-(4-amino)-phenyl-1-hydrogen-phenanthrene [9,10-d] imidazole as the fluorescence reagent. The results showed that the amounts of total fatty acids in sample 6 by applying SFE, UAE, and MAE were, respectively, 16.58 ± 0.14 mg/g, 18.11 ± 0.13 mg/g, and 15.09 ± 0.11 mg/g. As an environmental protection technology, SFE removed higher amounts of fatty acids than did MAE, but lower amounts of fatty acids than did UAE. In addition, the contents of the 16 fatty acids of Potentilla anserina L. from the 12 different producing areas Qinghai-Tibetan Plateau were significantly different. The differences were closely related to local altitudes and to climatic factors that corresponded to different altitudes (e.g., annual mean temperature, annual mean precipitation, annual evaporation, annual sunshine duration, annual solar radiation.). The temperature indices, photosynthetic radiation, ultraviolet radiation, soil factors, and other factors were different due to the different altitudes in the growing areas of Potentilla anserina L., which resulted in different nutrient contents.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Potentilla erecta (L.) Raeusch is a medicinal plant of the Northern hemisphere belonging to the plant family of roses (Rosaceae). It has traditionally been used to treat inflammatory disorders of the skin and mucous membranes as well as chronic diarrhea. AIM OF THE STUDY In the present study we analyzed the anti-inflammatory and vasoconstrictive effect of a Potentilla erecta extract (PE) and questioned if PE is similar effective as mild corticosteroids. Then we analyzed if PE acts in the skin via a similar mode of action as corticosteroids. MATERIAL AND METHODS The anti-inflammatory effect of PE was analyzed in irradiated HaCaT keratinocytes by measuring the formation of IL-6 and PGE2. Additionally the effect of PE on TNF-α induced NF-κB activation was determined. As the anti-inflammatory effect of corticosteroids correlates with their vasoconstrictive properties we tested if PE displays also vasoconstriction. Therefore we performed an occlusive patch test and a collagen contraction assay. Furthermore the binding of PE to the glucocorticoid receptor was determined with stainings and reporter assays. The interaction of PE on the nitric oxide (NO) content was examined with radical scavenging and endothelial NO synthase (eNOS) reporter assays. RESULTS In irradiated or TNF-α stimulated HaCaT cells the formation of IL-6 and PGE2 or NF-κB activation was strongly reduced by PE. Furthermore PE showed a blanching effect comparable to hydrocortisone. However, in contrast to glucocorticoids, PE did not cause nuclear translocation of the glucocorticoid receptor in HaCaT cells. The blanching effect of PE was at least partly attributable to a scavenging effect of NO and inhibition of eNOS. CONCLUSIONS PE displays anti-inflammatory and vasoconstrictive effects and might therefore be beneficial for the topical treatment of inflammatory skin disorders.

Abstract
OBJECTIVE To establish an UHPLC method for simultaneous determination of six flavonoid components of three closelyrelated plants Agrimonia pilosa,Potentilla chinensis and Potentilla discolor including rutin,hyperoside,cynaroside,quercetin,apigenin and kaempferol. Meanwhile three fresh and dry plants were evaluated to compare the contents of six flavonoid components. METHODS The samples were pretreated with ultrasonic extraction with 70% ethanol for 0. 5 h. The analysis was performed on an Acquity HSS T3( 100 mm × 3. 0 mm,1. 8 μm) column with the mobile phase consisting of acetonitrile and 0. 3% glacial acetic acid aqueous at a flow rate of0. 4 m L / min. The detection wavelength was 360 nm,and the column temperature was 35 ℃. RESULTS The contents of rutin and hyperoside were high generally,but the content of kaempferol was extremely low in three closely-related plants. The content of apigenin was0. 028 mg / g in Potentilla chinensis,but not detected in Agrimonia pilosa and Potentilla discolor. The content of cymaroside in Agrimonia pilosa was significantly higher than that in Potentilla chinensis and Potentilla discolor. The fresh plants of Potentilla chinensis and Potentilla discolor contained more flavonoids than oven drying plants. CONCLUSION The similar trend of content change from fresh to dry plant has showed a chemotaxonomic relationship of Potentilla chinensis and Potentilla discolor. The established determination method is simple,rapid and efficient,and is applicable for analysis of the contents of flavonoids in three closely-related plants,which provides the scientific basis for rationalization of using these drugs in clinic.

Abstract
UNLABELLED Context The root of Potentilla anserina L. (Rosaceae) is an herbal medicine that has been used as an antitussive and expectorant drug for thousands of years in Chinese folk medicine. OBJECTIVE This study estimated the antitussive and expectorant effects of P. anserina extract to validate its traditional use. Materials and methods The antitussive and expectorant activities of the ethanol extract, aqueous extract, and polysaccharides from P. anserina were evaluated using classical animal models. Results The results showed that in three antitussive tests, the aqueous extract and polysaccharides at high and low doses significantly inhibited the frequency of cough induced by ammonia and sulfur dioxide in mice and by citric acid in guinea pigs, and increased the latent period of cough in guinea pigs. Similarly, the aqueous extract and polysaccharides also showed significant expectorant activity compared with the control in phenol red secretion experiments. Polysaccharides at dose of 600 mg/kg enhanced tracheal phenol red output by 121.1%, the ammonium chloride (positive control) at dose of 1000 mg/kg by 117.4%. However, the ethanol extract at a high dose (600 mg/kg) has antitussive activity only in the sulfur dioxide induced coughing test. Moreover, the polysaccharides at the same dose showed better bioactivity than the aqueous extract in all tests. Discussion and conclusion The results of the present study provide evidence that P. anserina can be used as an antitussive and expectorant herbal medicine and that polysaccharides may be the main active ingredients of P. anserina responsible for its bioactivities.

Abstract
Grazing is one of the main artificial driving forces for the degradation succession process of alpine meadow. In order to quantitatively study the temperature sensitivity of alpine meadow ecosystem respiration in different degradation stages, we conducted the research in Haibei Alpine Meadow Ecosystem Research Station, CAS from July 2003 to July 2004. The static chamber-chromatography methodology was used to observe the seasonal changes of alpine scrub ecosystem respiration flux during different degradation stages. The results showed that: (1) The seasonal changes of ecosystem respiration flux in different degradation stages of alpine shrub presented a unimodal curve. The maximum appeared in August and the minimum appeared during the period from October to next April. The degradation succession process significantly decreased the ecosystem respiratory CO2 release rate. The respiratory rate ranges of alpine Potentilla fruticosa scrub (GG), Kobresia capillifolia meadow (GC) and bare land (GL) were 34.21-1 168.23, 2.30-1 112.38 and 20.40-509.72 mg (m2 x h)(-1), respectively. The average respiration rate of GG was 1.29 and 2.56 times of that of GC and GL, respectively; (2) Temperature was the main factor that affected the ecosystem respiration rate, and contributed 25% - 79% of the variation of the ecosystem respiration. The degradation succession process significantly changed the correlation between ecosystem respiration rate and temperature. The correlation (R2) between ecosystem respiration rate and each temperature indicator (T(s), T(d) and T(a)) was reduced by 47.23%, 46.95% and 55.28%, respectively when the ground vegetation disappeared and the scrub was degraded into secondary bare land; (3) The difference of Q10 between warm and cool seasons was significant (P < 0.05), and the value of cold season was larger than that of warm season. Degradation succession process apparently changed the temperature sensitivity of ecosystem respiration. The Q10 values of GG, GC and GL were 2.38, 2.91 and 1.62, respectively. Q10 of GC was increased by 22.26% and that of GL was decreased by 31.93% compared with that of GG.

Abstract
Superoxide dismutase (SOD) catalyzes the dismutation of superoxide radicals (O₂( ·-)) to molecular oxygen (O₂) and hydrogen peroxide (H₂O₂). Previously, we have identified and characterized a thermo-tolerant copper-zinc superoxide dismutase from Potentilla atrosanguinea (PaSOD), which retains its activity in the presence of NaCl. In the present study, we show that cotyledonary explants of PaSOD overexpressing transgenic Arabidopsis thaliana exhibit early callus induction and high shoot regenerative capacity than wild-type (WT) explants. Growth kinetic studies showed that transgenic lines have 2.6-3.3-folds higher growth rate of calli compared to WT. Regeneration frequency of calli developed from transgenic cotyledons was found to be 1.5-2.5-folds higher than that of WT explants on Murashige and Skoog medium supplemented with different concentrations of naphthalene acetic acid (NAA) and 6-benzylaminopurine (BAP) within 2 weeks. A positive regulatory effect of PaSOD and H₂O₂ was observed on different stages of callusing and regeneration. However, this effect was more pronounced at the early stages of the regeneration processes in transgenic lines as compared to WT. These results clearly indicate that plant regeneration is regulated by endogenous H₂O₂ and by factors, which enhance its accumulation. Transgenics also exhibited salt stress tolerance with higher SOD activity, chlorophyll content, total soluble sugars, and proline content, while lower ion leakage and less reduction in relative water content, as compared to WT. Thus, it appears that the activation of PaSOD at regeneration stage accompanied by increased H₂O₂ production can be one of the mechanisms controlling in vitro morphogenesis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Potentilla fulgens (Wall.) ex Hook. (Rosaceae) is a potent medicinal plant of the Western Himalayas, known under the name "Himalayan Cinquefoil or Bajradanti", and has been used traditionally to treat ailments including peptic ulcers, mouth ulcers, diarrhea, diabetes and cancer. OBJECTIVE The aim of the present study was to scientifically evaluate the gastric-ulcer protective effect of P. fulgens ethanolic root extract (EPF) on experimental rats. MATERIAL AND METHODS The gastroprotective activity of EPF was evaluated on four gastric-ulcer models such as pyloric ligation (PL), ethanol (EtOH), cold restrain stress (CRS) and aspirin (ASP)-induced gastric ulcers. The gastric acid obtained from 4h PL-induced gastric ulcer rats was determined for total volume content, pH and total acid-pepsin output. Total carbohydrates and protein ratio, expressed as index of mucin activity, and DNA content were estimated in the gastric juice and gastric mucosal tissue. The microvascular permeability, H(+)K(+)-ATPase activity, gastric mucus and histamine content were also determined. The levels of antioxidant enzymes (superoxide dismutase, catalase, and glutathione) and malondialdehyde in the stomach tissue (mucosal scrapings) were quantified. A histopathological study of the stomach was evaluated using eosin-haematoxylin stain. RESULTS EPF (200-400mg/kg, p.o.) showed significant protection against acute gastric-ulcer induced by EtOH, PL and CRS (400mg/kg, p.o.), but was found to be ineffective against ASP-induced ulcerogens. The effect of EPF on gastric juice studies in 4h PL rats significantly produced an increased level in gastric pH, whereas the effect on gastric volume and acid-pepsin output was observed to decrease significantly. However, EPF was found to have no significant effect on the defensive factors, thus revealing its antisecretory property by inhibiting the aggressive factors. EPF, significantly decreased the histamine level, inhibited the H(+)K(+)-ATPase activity and prevented the microvascular injury caused by ethanol in the rat stomach. Moreover, it was also observed to have antioxidant effects by producing a significant increase in the levels of SOD, CAT, and GSH and decreased the LPO activity. Histopathological studies showed that EPF significantly prevented gastric lesions caused by ethanol. CONCLUSIONS The present study showed that EPF has potent gastroprotective and antisecretory effects, thus justifying the traditional usage of this herb to treat gastric ulcers.

Abstract
This study examined the effect of Asiatic acid from Potentilla chinensis (AAPC) on chronic ethanol-induced hepatic injury. Rats underwent intragastric administration of ethanol (5.0–9.0 g/kg) once a day for 12 weeks. A subset of rats were also intragastrically treated with AAPC (2, 4 or 8 mg/kg) once a day. In the end, AAPC treatment significantly protected against ethanol-induced liver injury, as evidenced by the decrease in serum alanine and aspartate aminotransferases levels and the attenuation of histopathological changes in rats. Additionally, AAPC significantly decreased blood alcohol and acetaldehyde concentrations by enhancing alcohol dehydrogenase and aldehyde dehydrogenase activities. Mechanistically, studies showed that AAPC remarkably alleviated the formations of malondialdehyde and myeloperoxidase, restored impaired antioxidants, including superoxide dismutase, glutathione peroxidase, glutathione reductase and catalase, and inhibited cytochrome P450 (CYP)2E1 activity. Moreover, the over-expression of cytokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), the elevated plasma endotoxin level and the up-regulated Toll-like receptor 4 (TLR4), CD14 and myeloid differentiation factor 88 (MyD88) as well as nuclear factor-κB were also suppressed by AAPC in ethanol-intoxicated rats. In conclusion, the protective effect of AAPC on ethanol-induced hepatotoxicity was mainly due to its ability to attenuate oxidative stress and inhibit Kupffer cell activation by decreasing the level of plasma endotoxin and the expression of TLR4, CD14 and MyD88.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Three important Anglo-Saxon medical texts from the 10th century contain herbal formulations for over 250 plant species, many of which have yet to be evaluated for their phytochemical and/or pharmacological properties. In this study, three native British plants were selected to determine antimicrobial activity relevant to treating bacterial infections and wounds. MATERIALS AND METHODS Several preparations of Agrimonia eupatoria L., Arctium minus (Hill) Bernh. and Potentilla reptans L. were screened for antimicrobial activity against selected Gram-positive and Gram-negative bacteria of relevance in wounds using a 96 well plate microdilution method (200, 40 and 8μg/mL). Minimum inhibitory concentration (MIC) values were determined for the most potent extracts from 2 to 0.004mg/mL and HPLC chromatograms examined by multivariate analysis. Principle components analysis (PCA) was used to identify chemical differences between antimicrobial activity of the crude extracts. RESULTS The HPLC-PCA score plots attributed HPLC peaks to the antimicrobial activity with all three plants inhibiting growth of Gram-positive Staphylococcus aureus by >50% in four or more extracts. The first two principal components (PC) represented 87% of the dataset variance. The P. reptans 75% ethanol root extract exhibited the greatest range of activity with MIC(50) at 31.25μg/mL to a total MIC that was also the minimum bactericidal concentration (MBC) at 1mg/mL. Additionally, the root of P. reptans, inhibited growth of Gram-negative bacteria with the 75% ethanol extract having a MIC(50) at 1mg/mL against Pseudomonas aeruginosa and the decoction a MIC(50) at 3.9μg/mL against Escherichia coli. CONCLUSIONS The results indicate a moderate antimicrobial activity against common wound pathogens for P. reptans suggesting it may well have been effective for treating wound and bacterial infections. Anglo-Saxon literary heritage may provide a credible basis for researching new antimicrobial formulations. Our approach encompassing advanced analytical technologies and chemometric models paves the way for systematic investigation of Anglo-Saxon medical literature for further therapeutic indications to uncover knowledge of native British plants, some of which are currently lost to modern Western herbal medicine.

Abstract
OBJECTIVE To observe the protective effect of alcohol extract of Potentilla anserina against myocardial apoptosis induced by acute myocardial ischemia/reperfusion by arteria coronaria ligation and the effect on the expressions of Caspase-3 and Caspase-9 in myocardial apoptosis signal pathway. METHOD Male SD rats were randomly divided into the sham-operated group, the model group, the diltiazem group (30 mg x kg(-1)) and P. anserine alcohol extract intervention groups (0.9, 1.8, 3.6 g x kg(-1)). Rat acute myocardial ischemia/reperfusion model was established by ligating left anterior descending. Apoptosis of myocardial cells were detected by TUNEL (Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay). The expressions of Caspase-3 and Caspase-9 mRNA were assayed by reverse transcription-polymerase chain reaction (RT-PCR). Semi-quantitative analysis was made for the expressions of Caspase-3 and Caspase-9 by immunohistochemistry. RESULT According to TUNEL results, after I/R injury-induced myocardial apoptosis, the apoptotic index (AI) of model group was (31.5 +/- 3.6)%. All P. anserine alcohol extract intervention groups showed obvious inhibition of ischemia/reperfusion-induced myocardial apoptosis. In the model group, myocardial apoptosis caused increased expression of Caspase-3, Caspase-9 mRNA and proteins. After the administration of P. anserine alcohol extract, 1.8, 3.6 g x kg(-1) dose groups showed notable decrease in Caspase-9 mRNA (P < 0.05), while the 0.9 g x kg(-1) dose group showed no significant difference with the model group. Alcohol extract of P. anserina in all dosages showed inhibitory effect on the expression of Caspase-3 mRNA in myocardial cells compared with model group (P < 0.05). Immunohistochemistry showed that administration of all dosages of alcohol extract of P. anserina could significantly reduce Caspase-3 and Caspase-9 protein expressions after I/R injury (P < 0.05). CONCLUSION The administration with alcohol extract of P. anserina can protect the myocardial tissue from apoptosis after acute myocardial ischemia and reperfusion injury in rats and inhibit the expressions of Caspase-9 and Caspase-3 mRNA and proteins.

Abstract
CONTEXT Potentilla alba L. (Rosaceae) rhizomes have anti-inflammatory, antioxidant, and adaptogenic effects and are used for the treatment of diarrhea and intestinal colic. However, the data concerning the adaptogenic and central nervous system activities of P. alba are fragmentary. OBJECTIVES To determine the effect of oral administration of dried P. alba extract on the swimming endurance, light/dark exploration, and open-field tests for mice. MATERIALS AND METHODS The mice were orally administered Rhodiola rosea extract (RR group); dry extract of P. alba at doses of 12, 36, or 72 mg/kg (groups: PA12, PA36, and PA72); or distilled water (control group) for 7 consecutive days. RESULTS The swimming times of the RR, PA36, and PA72 groups were significantly longer than those of the control group. The administration of P. alba significantly increased the light time, latency time, and the number of rearings in a dose-dependent manner. In the open-field test, the P. alba extract at a dose of 12 mg/kg produced a significant increase in the frequency of head dipping and the number of squares crossed and a significant decrease in grooming compared with the control treatment. CONCLUSION The current findings demonstrate that P. alba extracts significantly increased swimming endurance time and have anxiolytic-like action with a predominant locomotor component.

Abstract
AIM OF THE STUDY Potentilla discolor Bunge, commonly found at the north temperate and boreal zone, has been used for diabetes in China for a long time. Flavonoids and triterpenoids are two major types of compounds in P. discolor. This study was designed primarily to investigate the effects of total flavonoids extract (TFE) and total triterpenoids extract (TTE) of P. discolor Bunge on blood glucose, lipid profiles and antioxidant parameters on diabetic rats induced by high fat diet and streptozotocin. MATERIALS AND METHODS High fat diet-fed and streptozotocin-induced diabetic rats were treated with the TFE and TTE for 15 days, respectively. A range of parameters were tested including fasting blood glucose (FBG), serum insulin (SI), blood lipid profile, malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH), glycosylated serum protein (GSP), and nitric oxide (NO). RESULTS Diabetic rats treated with TFE or TTE had decreased concentration of FBG and GSP compared with the control group. Meanwhile, the levels of serum total cholesterol (TC), triglycerides (TG) and low-density lipoprotein cholesterol (LDL-c) in the TFE or TTE treated diabetic rats were lower, and the high-density lipoprotein cholesterol (HDL-c) level was higher than in the control diabetic rats. Furthermore, the extracts treatment decreased the MDA and NO level, while increased SOD and GSH levels in diabetic rats. Histopathologic examination also showed that the extracts have protective effects on β-cells in diabetic rats which are supported by the increase of SI. CONCLUSIONS All these experimental results highlighted the hypoglycemic and hypolipidemic properties of the two extracts from Potentilla discolor Bunge on diabetes and its complications, possibly through a strong antioxidant activity and a protective action on β-cells.

Abstract
A water-soluble polysaccharide fraction from root of Potentilla anserine was obtained. Gas chromatogram, FT-IR, physical and chemical characteristics of the Potentilla anserine polysaccharide fraction (PAPF) were analyzed. The protective effects of PAPF against the H2O2 induced process of apoptosis of murine splenic lymphocytes were investigated in vitro. Morphological assessment of apoptosis was performed with light microscope and laser scanning confocal microscope. DNA fragmentation was visualized by agarose gel electrophoresis. The amount of apoptotic cells was measured by flow cytometry. The results showed that PAPF is composed of rhamnose, arabinose glucose and galactose. H2O2 (200 micromol x L(-1)) induced apoptosis of murine splenic lymphocytes with the cell volume reduced, cytoplasm and nuclear shrunk and DNA stained non-uniformly. Condensed chromatin and formation of apoptotic body were observed in the apoptotic cells. Apoptotic bodies in the cells treated with PAPF and H2O2 were less than those in H2O2 treatment alone. DNA fragmentation assay showed that PAPF (50, 100, 200, and 400 microg x mL(-1)) obviously reduced H2O2-induced ladder bands. Flow cytometry analysis showed that H2O2 increased the populations of apoptotic sub-G1 cells from 5.60% (control) to 45.40%, and PAPF decreased H2O2-induced apoptosis to 37.80%, 22.70%, 17.70%, and 8.50%, respectively. In conclusion, PAPF reduced H2O2-induced oxidative damage in a dose dependent manner.

Abstract
Ethanolic and aqueous extracts from five plant species used in Turkish traditional medicine were evaluated for in vivo hypercholesterolaemic and antioxidant activities: Agrostemma githago L., Potentilla reptans L., Thymbra spicata var. spicata L., Urtica dioica L. and Viscum album var. album L. We assayed the effects of the administration of plant extracts on serum total cholesterol, triglyceride, HDL-C, LDL-C, glucose, AST and ALT concentrations in mice fed with cholesterol-rich diet. In addition, plasma TAA, MDA and NO(x) levels in the same animals were assayed. All the aqueous plant extracts did not affect the serum cholesterol concentration. However, the ethanolic extracts of Agrostemma githago, Thymbra spicata and Viscum album decreased the serum cholesterol concentration in the mice fed with high-cholesterol diet without inducing any gastric damage. The ethanolic extracts of Thymbra spicata, Viscum album, Potentilla reptans and Urtica dioica and the aqueous extract of Agrostemma githago increased the serum HDL concentration, whereas the ethanolic extracts of Agrostemma githago, Thymbra spicata, Viscum album and Urtica dioica decreased the serum LDL-C concentration. Thymbra spicata and Viscum album were observed to decrease the serum triglyceride concentration. Among the plant extracts studied, the ethanolic extracts of Thymbra spicata significantly decreased the MDA level in mice. The ethanolic extract of Potentilla reptans increased in NO(x). None of these plants showed statistically prominent activity on plasma TAA. Results of the present study indicated that the ethanolic extracts of Agrostemma githago, Thymbra spicata and Viscum album showed potent hypocholesterolaemic activity in the mice fed with a diet containing high-cholesterol.

Abstract
The antioxidant activities of five medicinal plants (Ampelopsis sinica, Ampelopsis humiliforlia var. heterophylla, Potentilla freyniana, Selaginella labordei and Chrysanthemum multiflorum), used in the Hubei province of China, have been investigated using both enzymatic and non-enzymatic in vitro antioxidant assays. Extracts from all five of the plants inhibited xanthine oxidase and lipoxygenase activities, and were scavengers of the ABTS*+ radical cation using the Trolox equivalent antioxidant capacity assay (TEAC). Extracts from Potentilla freyniana and Selaginella labordei down-regulated cyclooxygenase-2 gene expression, measured by real-time RT-PCR, in human colon adenocarcinoma CaCo-2 cells.

Abstract
Total five plants, three from Mizoram (Dillenia pentagyna, Ageratum conyzoides, Blumea lanceolaria) and two from Meghalaya (Potentilla fulgens, Taxus baccata) were studied for their antitumour activity against murine ascites Dalton's lymphoma (DL) in vivo. Only three plants showed the different magnitude of antitumour activity. Out of these three plants, the antitumour activity was maximally observed with the methanol extract of the stem bark of D. pentagyna as compared to the aqueous extract of the roots of A. conyzoides and aqueous extract of the root of P. fulgens. An increase in glutathione levels in Dalton's lymphoma cells was observed during tumour growth. Changes in glutathione and protein levels were also investigated in the liver and Dalton's lymphoma cells of tumour-bearing mice following the treatment with the extract of D. pentagyna which showed the highest antitumour activity as compared to the other two plant extracts. Glutathione in the liver and DL cells of treated tumour-bearing mice was found to be decreased. The protein concentration in liver and DL cells decreased mainly at 96 hr of treatment. It may be concluded that the natural product of D. pentagyna promises to be more active against Dalton's lymphoma than others and the decrease in glutathione level may be one of the important steps in resulting this antitumour effect.

Abstract
Tap roots of Potentilla fulgens L. traditionally chewed along with betel nut (Areca catechu) and betel leaves (Piper betel), are commonly used by local practitioners for various types of ailments. The crude methanolic extract of the roots was tested for its effects in normoglycemic and alloxan-induced diabetic mice. Hypoglycemic activity was observed to be dose- and time- dependent. The extracts reduced blood glucose level 2 h following administration in both normal and alloxan-induced diabetic mice. In alloxan-induced diabetic mice blood glucose was markedly reduced by 63%, while in normal mice a 31% reduction was observed 24 h after the effective dose of extract was administered. Further, in the diabetic mice a prolonged anti-hyperglycemic action was observed where glucose levels was, found to be significantly low (79%) when compared with control even on the third day. Glucose tolerance was also improved in both normal and diabetic mice. The results were compared against those of insulin, glibenclamide, metformin, and the probable mechanism of action is discussed.
