Aschers flower modulates inflammation and amino acid metabolism by inhibiting NF-κB/MAPK/JAK-STAT/PI3K-Akt and AMPK pathways to alleviate benign prostatic hyperplasia in rats. JOURNAL OF ETHNOPHARMACOLOGY 2024:118970. [PMID: 39433163 DOI: 10.1016/j.jep.2024.118970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/17/2024] [Revised: 09/18/2024] [Accepted: 10/18/2024] [Indexed: 10/23/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Benign prostatic hyperplasia (BPH) is the most common urogenital disease in men with no definitive treatment. Inflammation, androgen imbalance, and oxidative stress play crucial roles in the pathogenesis of BPH. The flower of Hosta plantaginea (Lam.) Ascher is a pivotal medicinal plant in China, used to treat BPH. However, its effect and mechanism against BPH have not been clear. AIM OF THE STUDY Our aim was to decipher the pharmacodynamics and mechanisms of H. plantaginea flower against BPH. MATERIALS AND METHODS The extract yields and HPLC-based chemoprofile of ethanolic extract (HP) and total flavonoid (TF) of H. plantaginea flowers were used as reference standard to ensure their quality. The testosterone propionate-induced BPH rat model was used to assess the effects of HP and TF. Protein expression, metabolomics, and network pharmacology analyses were performed. RESULTS Twenty constituents were identified in both HP and TF, with four quantitatively analyzed using the HPLC method. HP and TF demonstrated significant therapeutic effects on BPH, including reduced prostate size and prostatic index, improved pathological injury of prostate, as well as increased levels of testosterone, superoxide dismutase, glutathione, and glutathione peroxidase, along with decreased levels of dihydrotestosterone, 5 alpha-reductase, epidermal growth factor, TNF-α, IL-1β, IL-6, and malondialdehyde. Western blotting assay indicated that HP and TF prominently inhibited the protein expression of phosphorylated p65, IκBα, JNK, p38, Erk1/2, JAK1, STAT3, PI3K, Akt, and AMPKα1 in a dose-dependent manner. Integrating metabolomics and network pharmacology analyses revealed that HP and TF observably regulated 30 differential metabolites and 11 hub genes across the aforementioned pathways, which are closely associated with amino acid metabolism. CONCLUSION The proposed comprehensive strategy of in vivo experiments, metabolomics, and network pharmacology studies has demonstrated that HP and TF could alleviate BPH injury in rats by suppressing inflammation, androgen imbalance, oxidative stress, and amino acid metabolism through the inhibition of NF-κB, MAPK, JAK-STAT, PI3K-Akt, and AMPK pathways, which provides novel insights into the potential of H. plantaginea flower as a treatment for BPH.

Abstract
This study identified a new species (Cercospora polygonatum) that causes gray leaf spot (GLS) disease in cultivated Polygonatum cyrtonema. This fungal species was isolated from the affected region of GLS on P. cyrtonema leaves. Pathogenicity bioassays were conducted based on Koch's postulates. Morphology was examined based on the features of conidiomata, conidiogenous loci, conidia/conidiophores, and conidiogenous cells. The rDNA internal transcribed spacer region, calmodulin, translation elongation factor 1-alpha, and histone genes were subjected to phylogenetic analysis using the MrBayes tool in Phylosuite. Bootstrap support analysis for phylogenetic placement confirmed the new species, which was significantly different from the closely related species C. senecionis-walkeri and C. zeae-maydis. The morphological characteristics also supported this finding, with the conidiogenous cells of C. polygonatum being considerably shorter than those of C. senecionis-walkeri or C. zeae-maydis. In addition, C. polygonatum was distinguished by its cultural characteristics. As this fungus was isolated from P. cyrtonema, it was named C. polygonatum F.Q. Yin, M. Liu & W.L. Ma, sp. nov. The type specimen (H8-2) was preserved at the China General Microbiological Culture Collection Center. This is the first report of GLS caused by C. polygonatum on P. cyrtonema leaves in China. The current study enriches the knowledge regarding Cercospora sp., contributes to the identification of a species causing GLS in P. cyrtonema, and provides useful information for the effective management of this disease.

[PMID: 38740341 DOI: 10.1016/j.fitote.2024.106010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 04/23/2024] [Accepted: 05/11/2024] [Indexed: 05/16/2024]
Abstract
Flowers of Hosta plantaginea (H. plantaginea), a widely utilized medicinal herb in Mongolian medicine, holds a significant historical background in terms of its medicinal applications. This herb is renowned for its ability to clear heat and detoxify the body, alleviate cough, and provide relief to the throat. However, the active ingredients and the potential mechanism of action remain ambiguity. The objective of this study was to conduct a comprehensive analysis of the efficacy of H. plantaginea in treating pneumonia, identify its active ingredients and unveil the pharmacological mechanism in the treatment of pneumonia. In vivo experiments demonstrate the plant's anti-pneumonia properties, while mass spectrometry analysis identifies 62 chemicals, with 14 absorbed into the bloodstream. Network pharmacology and Venn analysis reveal 195 targets of 52 active ingredients, with 49 gene targets common to H. plantaginea and pneumonia. Protein-protein interaction (PPI) network construction and enrichment analysis highlight the key targets and pathways such as AKT, EGFR, IL-17. Western blotting confirms downregulation of these pathways, indicating the anti-inflammatory effects of H. plantaginea in treating acute lung injury. Our findings showed that the treatment of ALI with the H. plantaginea exerts its anti-inflammatory effects through multiple components, targets, and pathways. This study established a solid experimental foundation for investigating the various components, targets, and pathways involved in the treatment of pneumonia using H. plantaginea. It offers valuable insights from multiple perspectives and can serve as a reference for the clinical application of this plant in pneumonia treatment.

Abstract
BACKGROUND Hosta plantaginea (Lam.) Aschers flower is a famous Mongolian folk medicine in China and has a therapeutic effect on acute pharyngitis (AP). However, the effect and potential mechanism of H. plantaginea flower on AP have not been fully elucidated. AIM OF THE STUDY The present work aimed to evaluate the effects and mechanisms of the crude extract of H. plantaginea flowers (HP) and its four fractions of petroleum ether fraction (HPA), ethyl acetate fraction (HPB), n-butanol fraction (HPC), and water residue (HPD) against AP in rats. MATERIALS AND METHODS A 15% ammonia-induced AP rat model in rats was established. Therapeutic effects of HP and HPA∼D in model rats were evaluated based on body weight, histopathological analysis, and inflammatory parameters, including tumor necrosis factor α (TNF-α), prostaglandin E2 (PGE2), interleukin 1β (IL-1β), and IL-6. The protein expression of nuclear factor kappa-B p65 (NF-κB p65), inhibitor of NF-κB alpha (IκBα), c-Jun N-terminal kinases (JNK), mitogen-activated protein kinase (MAPK) p38, extracellular signal-regulated kinase (Erk), just another kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt) were detected by a Western blotting assay. RESULTS HP, HPB, and HPC treatments markedly alleviated AP in rats by increasing body weight and improving pathological damages in pharyngeal tissues. In addition, HP, HPB, and HPC treatments significantly inhibited inflammation, including decreasing the levels of TNF-α, PGE2, IL-1β, and IL-6, and suppressing phosphorylated protein expression of p65, IκBα, JNK, p38, Erk, JAK1, STAT3, PI3K, and Akt in pharyngeal tissues of rats. CONCLUSION Collectively, HP, HPB, and HPC can attenuate pharynx injury in rats by suppressing inflammation via inhibition of NF-κB, MAPKs, JAK-STAT, and PI3K-Akt pathways, which supports the traditional use of H. plantaginea flowers.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hosta plantaginea (Lam.) Aschers flower is an important Mongolian medicine beneficial in the treatment of chronic prostatitis (CP) in the absence of scientific evidence. AIM OF THE STUDY The aim of this study was to reveal the therapeutical effects and potential mechanisms of H. plantaginea flowers extract (HP) and its different polarity fractions (HPA∼D) on autoimmune CP (ACP) model rats. MATERIALS AND METHODS Sprague-Dawley male rats were randomly assigned to 13 groups (n = 6/group). Except the sham group, all rats were injected with a mixture of prostate antigen and complete Freund's adjuvant on days 0, 7, and 21 to establish ACP model rats. Afterwards, ACP model rats were orally gavaged with HP or HPA∼D (1 and 4 g/kg of raw herbal material) or positive drug (Prostat, 200 mg/kg) daily from day 21 to day 50 for 30 days, while the sham and model groups were treated simultaneously with isopyknic of 0.3% sodium carboxymethyl cellulose. Histopathological analysis, biochemical parameters, and protein expression of prostate tissues were investigated. RESULTS In comparison with the model group, all fraction groups experienced improved CP effects, including restored body weight, reduced prostate gland edema and prostate index, decreased prostatic leukocytes, increased prostatic lecithin bodies, and alleviated histopathological damage to prostate tissue. Furthermore, all fraction groups markedly inhibited the phosphorylated protein of nuclear factor kappa-B p65 (NF-κB p65), NF-κB inhibitor alpha (IκBα), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinase (Erk), just another kinase 1 (JAK1), signal transducer and activator of transcription 3 (STAT3), phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt) than the model group. CONCLUSION All fractions of HP exerted significant anti-CP effects by inhibiting NF-κB, MAPKs, JAK-STAT and PI3K-Akt pathways in ACP model rats. These findings provide scientific evidence that H. plantaginea flowers can be used as a pivotal Mongolian medicine in clinical applications for the treatment of CP.

Abstract
Hosta plantaginea (Lam.) Aschers flower is traditionally used in China as an important herbal medicine for the treatment of inflammatory disease. The present study isolated one new compound, namely (3R)-dihydrobonducellin (1), and five known ones, p-hydroxycinnamic acid (2), paprazine (3), thymidine (4), bis(2-ethylhexyl) phthalate (5), and dibutyl phthalate (6) from H. plantaginea flowers. These structures were elucidated from spectroscopic data. Among them, compounds 1-4 remarkably suppressed nitric oxide (NO) production in lipopolysaccharide (LPS)-induced RAW 264.7 cells with half maximal inhibitory concentration (IC50) values of 19.88 ± 1.81, 39.80 ± 0.85, 19.03 ± 2.35, and 34.63 ± 2.38 μM, respectively. Furthermore, compounds 1 and 3 (20 μM) significantly decreased levels of tumor necrosis factor α (TNF-α), prostaglandin E2 (PGE2), interleukin 1β (IL-1β), and IL-6. Additionally, compounds 1 and 3 (20 μM) prominently reduced the phosphorylation protein level of nuclear factor kappa-B (NF-κB) p65. The present findings indicated that compounds 1 and 3 may be new candidates against inflammation via blocking the NF-κB signaling pathway.

Abstract
Kaempferol 3-O-(2G-glucosylrutinoside)-7-O-glucoside (KGG) has isolated from Hosta plantaginea flowers and possessed an inhibitory effect on cyclooxygenase 2 (COX-2), could be effective in inhibiting inflammation. However, the anti-inflammatory activity and mechanism of KGG remain unknown. In this study, for the first time, the anti-inflammatory effect of KGG and its potential molecular mechanisms were explored in cells. KGG had no cytotoxicity at concentrations of 1.25, 2.5, 5, 10, 20, and 40 μM by Cell Counting kit-8 assay in RAW 264.7 cells. Besides, KGG concentration-dependently (1.25, 2.5, and 5 μM) inhibited secretions of nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), and IL-6 in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Western blot showed that the phosphorylation of nuclear factor kappa-B (NF-κB) p65, inhibitor of NF-κB (IκB), p38 MAPK, c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinase (Erk), and protein kinase B (Akt), together with inducible nitric oxide synthase (iNOS) and COX-2 were significantly attenuated by KGG (1.25, 2.5, and 5 μM) in a concentration-dependent relationship. Meanwhile, KGG remarkably enhanced the protein expression of IκB. Taken together, KGG may be one of bioactive phytochemicals from H. plantaginea flowers, and be an anti-inflammatory agent via inhibiting NF-κB, mitogen-activated protein kinases (MAPKs), and Akt signaling pathways.

Abstract
The Hosta hybrid cultivar ‘So Sweet’, an important ornamental and widely used horticultural plant, is noted for its rich, fragrant white flowers. The main aroma components of Hosta flowers are terpenoids, mainly monoterpenes. Until now, the terpene synthases responsible for terpene production in Hosta were not described. In this study, two terpene synthase (TPS) genes (HsTPS1 and HsTPS2) were cloned and characterized to further study their function. Furthermore, the volatile terpenes of Hosta ’So Sweet’ in two flower development stages from two in vitro enzyme tests were analyzed by gas chromatography–mass spectrometry (GC–MS). We analyzed the expression levels of two genes at four different developmental stages using quantitative real-time PCR, while localization was analyzed using Nicotina benthamiana leaves. In vitro, the two proteins were identified to mainly produce linalool and nerol. In addition, the active products of the two recombinant proteins were (E,E)-farnesol and (E,E)-farnesal, respectively, using farnesyl pyrophosphate as a substrate. The high expression of HsTPS1 and HsTPS2 was correlated with the release of components of Hosta flowers. To our knowledge, this is the first time that the terpene synthase genes of Hosta species have been isolated and identified, providing an opportunity to study the terpene metabolic pathways in Hosta species.

Abstract
BACKGROUND The flower of Hosta plantaginea (Lam.) Aschers has traditionally been used in China as an important Mongolian medicine for the treatment of inflammatory diseases with limited scientific evidence. In previous studies, 16 flavonoids and 3 phenylethanoid glycosides (1-19) were isolated from the ethanolic extract of H. plantaginea flowers. Nevertheless, the anti-inflammatory effects of these constituents remain unclear. In the present study, the anti-inflammatory effects of these 19 constituents and their underlying mechanisms were assessed in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. METHODS The viability of RAW 264.7 macrophages was detected by Cell Counting Kit-8 (CCK-8) assay. Meanwhile, nitric oxide (NO) production was measured by Griess assay, while the secretion of tumor necrosis factor α (TNF-α), prostaglandin E2 (PGE2), interleukin 1β (IL-1β) and IL-6 in LPS-induced macrophages was determined by enzyme-linked immunosorbent assay (ELISA). Furthermore, the protein expression of nuclear factor kappa B (NF-κB) p65 and phosphorylated NF-κB p65 was evaluated by Western blot analysis. RESULTS All constituents effectively suppressed excessive NO production at a concentration of 40 μM with no toxicity to LPS-induced RAW 264.7 macrophages. Among them, five flavonoids (1, 4-6 and 15) and one phenylethanoid glycoside (17) remarkably prevented the overproduction of NO with median inhibitory concentration (IC50) values in the range of 12.20-19.91 μM. Moreover, compounds 1, 4-6, 15 and 17 potently inhibited the secretion of TNF-α, PGE2, IL-1β and IL-6, and had a prominent inhibitory effect on the down-regulation of the phosphorylated protein level of NF-κB p65. CONCLUSION Taken together, compounds 1, 4-6, 15 and 17 may be useful in managing inflammatory diseases by blocking the NF-κB signaling pathway and suppressing the overproduction of inflammatory mediators.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hostaflavone A (HA) is a new flavonoid component isolated from the flower of Hosta plantaginea (Lam.) Asch., which is commonly used as a folk herbal to treat inflammatory diseases in China. Nevertheless, the anti-inflammatory effect of HA remains unknown. AIM OF THE STUDY This work aimed to evaluate the HA with anti-inflammatory activity and mechanism in RAW 264.7 macrophages activated by lipopolysaccharide (LPS). MATERIALS AND METHODS Anti-inflammatory effect of HA was evaluated by measuring of cell viability, nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and IL-6 levels in RAW 264.7 cells. In parallel, the HA action mechanism of nuclear factor kappa B (NF-κB) p65, inhibitor of NF-κB (IκB), inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinase (Erk), p38, and protein kinase B (Akt) were detected by Western blot analysis. RESULTS HA has no cytotoxicity at concentrations as high as 40 μM. Besides, HA concentration-dependently clearly suppressed the overproduction of NO, PGE2, TNF-α, IL-1β and IL-6 in RAW 264.7 cells induced by LPS. In addition, HA remarkably reduced the upregulation of phosphorylated NF-κB p65, phosphorylated IκB, phosphorylated JNK, phosphorylated Erk and phosphorylated p38, together with iNOS and COX-2 protein expressions in a concentration-dependent manner. CONCLUSION HA blocked the LPS activated inflammation via suppressing NF-κB, iNOS, COX-2, mitogen-activated protein kinases (MAPKs) and Akt pathways in RAW 264.7 cells, and might be a new anti-inflammatory agent.

Abstract
The flowers of Hosta plantaginea (Lam.) Aschers are commonly used for the treatment of inflammatory diseases in traditional Chinese medicine with limited scientific evidence. Plantanone C (PC) is a new phytochemical isolated from H. plantaginea flowers; nevertheless, the anti-inflammatory effect remains unknown. Herein, we aimed to study the anti-inflammatory effects of PC and its underlying molecular mechanisms in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages. The cell viability of PC-treated RAW 264.7 macrophage was measured by the Cell Counting kit-8 (CCK-8) assay. The anti-inflammatory effect of PC was investigated by measuring the levels of inflammatory mediators and pro-inflammatory cytokines using the Griess reaction and enzyme-linked immunosorbent assay (ELISA). Furthermore, the mechanism of action of PC was evaluated by Western blot analysis. The results showed that PC was not cytotoxic at concentrations as high as 40 μM. Furthermore, PC potently suppressed LPS-stimulated overproduction of nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and IL-6 in RAW 264.7 macrophages. Western blot demonstrated that PC remarkably suppressed the phosphorylation of nuclear factor kappa-B (NF-κB) p65, inhibitor of NF-κB (IκB), c-Jun N-terminal kinases (JNK), extracellular signal-regulated kinase (Erk), p38, and protein kinase B (Akt), as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2) in a concentration-dependent manner. Taken together, these findings suggest that PC exhibits anti-inflammatory effects by inhibiting NF-κB, iNOS, COX-2, mitogen-activated protein kinases (MAPKs), and Akt signaling pathways in RAW 264.7 macrophages.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lagopsis supina (Steph.) Ik. -Gal. ex Knorr. has been widely used as a remedy treatment for diuresis and edema in China over 2500 years. Our previous results showed that the aqueous soluble fraction from L. supina (LSB) possessed acute diuretic effect. AIM OF THE STUDY The aim of this study was to appraise the acute (6 h) and prolonged (7 d) diuretic effects, underlying mechanisms, and chemical profiling of LSB. MATERIALS AND METHODS The chemical profiling of LSB was performed by ultra-high-performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry (UHPLC-qTOF-MS/MS). Then, oral administration of LSB (40, 80, 160 and 320 mg/kg) and furosemide (10 mg/kg) once daily for 7 consecutive days to evaluate the diuretic effects in saline-loaded rats. The body weight, food consumption, and water intake were recorded once daily. The urinary volume, pH and electrolyte concentrations (Na+, K+, Cl-, and Ca2+) were measured after administration drugs for acute and prolonged diuretic effects. In addition, the serum levels of Na+-K+-ATPase, angiotensin II (Ang II), anti-diuretic hormone (ADH), aldosterone (ALD), atriopeptin (ANP), aquaporins (AQPs)-1, 2 and 3 were determined by ELISA kits. The mRNA expressions and protein levels of AQPs-1, 2 and 3 were analyzed by real-time quantitative PCR and Western blot assays, respectively. RESULTS 30 compounds were identified in LSB based on accurate mass and MS/MS fragmentation compared to literature, among which phenylpropanoids and flavonoids could be partly responsible for the major diuretic effect. Daily administration of LSB (160 or 320 mg/kg) prominently increased urinary excretion volume after the 2 h at the first day of treatment, remaining until the 7th day. LSB did not cause Na+ and K+ electrolyte abnormalities, and has minor effect on Cl- and Ca2+ concentrations at 320 mg/kg. Furthermore, LSB observably suppressed renin-angiotensin-aldosterone system (RAAS) activation, including decreased serum levels of Ang II, ADH, and ALD, and prominently increased serum level of ANP in rats. LSB treatment significantly down-regulated the serum levels, mRNA expressions and protein levels of AQP1, AQP2, and AQP3. CONCLUSION LSB has a prominent acute and prolonged diuretic effects via suppression of AQP and RAAS pathways in saline-loaded rats, and support the traditional folk use of this plant. Taken together, LSB might be a potential diuretic agent.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Hosta (Liliaceae family) represents an interesting source of natural bio-constituents, and the 50 species of this genus are widespread in the world. Five species have been used as traditional East Asian medicines for treating inflammation and pain-related diseases. However, the available data for this genus have not been comprehensively reviewed regarding their extracts and secondary metabolites. AIM OF THE STUDY The present review aims to provide a deeper insight, better awareness and detailed knowledge of traditional uses, phytochemistry, pharmacology along with toxicological aspects of the genus Hosta in the past decades (February 1964 to August 2020). In addition, the relevance among traditional uses, pharmacology and phytochemistry in folk medicines were extensively discussed. MATERIALS AND METHODS The relevant information of Hosta species was obtained from several databases. Moreover, the medical books, PhD and MSc dissertations in Chinese were also used to perform this work. RESULTS Comprehensive analysis of the afore-mentioned databases, medical books and dissertations confirmed that ethnomedical uses of Hosta genus plants had been recorded in China, Japan, Korea and other countries. To date, only eight species have been studied for chemical constituents, and a total of 200 secondary metabolites (not include essential oil constituents), including steroids, flavonoids, alkaloids, furan derivatives, phenylpropanoids, phenethyl derivatives, terpenoids, aliphatics, and others. The crude extracts and isolated chemical constituents exhibited anti-inflammatory and analgesic, antioxidant, anti-tumor, anti-viral, acetylcholinesterase inhibitory, antimicrobial, anti-chronic prostatitis, and other effects. Moreover, only the n-butanol fraction of H. ventricosa (Salisb.) Stearn roots showed moderate acute toxicity in mice. In addition, the relevance among traditional uses, pharmacology and phytochemistry in folk medicines were extensively discussed. CONCLUSIONS Hosta spp. are plants rich in steroids and flavonoids with valuable medicinal properties; though, there are several gaps in understanding the traditional uses in the current available data. More high scientific quality preclinical studies with new methodology are necessary to assess the safety, efficacy and mechanism of these plants.

Abstract
The total phenolic and flavonoid contents (TPC and TFC) from the genus Hosta with antioxidant and α-glucosidase inhibitory activities were reported for the first time. Sixteen extracts from the aboveground and underground parts of the four Hosta species, including H. plantaginea, H. ventricosa, H. ensata, and H. albofarinosa, using reflux extraction (RE) and ultrasound-assisted extraction (UAE) techniques have high TPC and TFC with good antioxidant and α-glucosidase inhibitory activities. Furthermore, no significant differences on extraction yields, TPC, and TFC were found between RE and UAE techniques. Additionally, extracts from the aboveground parts of the four Hosta species had higher TPC, TFC, antioxidant, and α-glucosidase inhibitory activities compared to the underground parts by means of RE or UAE techniques. Lastly, the extracts of H. albo-marginata displayed a very remarkable α-glucosidase inhibitory activity compared to the positive control acarbose. The relationships of sixteen extracts of the four Hosta species were analyzed by RE and UAE techniques between extraction yields, TPC, TFC, antioxidant activity, and α-glucosidase inhibitory activity. The present study demonstrated that H. plantaginea, H. ventricosa, H. ensata, and H. albofarinosa could be new sources of natural antioxidants and antidiabetes for pharmaceutical and industrial purposes.

Abstract
Dendropanax dentiger root is a traditional medicinal plant in China and used to treat inflammatory diseases for centuries, but its phytochemical profiling and biological functions are still unknown. Thus, a rapid, efficient, and precise method based on ultra high-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF-MS/MS) was applied to rapidly analyse the phytochemical profiling of D. dentiger with anti-inflammatory and antioxidant activities in vitro. As a result, a total of 78 chemical compositions, including 15 phenylpropanoids, 15 alkaloids, 14 flavonoids, 14 fatty acids, 7 phenols, 4 steroids, 4 cyclic peptides, 3 terpenoids, and 2 others, were identified or tentatively characterized in the roots of D. dentiger. Moreover, alkaloid and cyclic peptide were reported from D. dentiger for the first time. In addition, the ethanol crude extract of D. dentiger roots exhibited remarkable anti-inflammatory activity against cyclooxygenase- (COX-) 2 inhibitory and antioxidant activities in vitro. This study is the first to explore the phytochemical analysis and COX-2 inhibitory activity of D. dentiger. This study can provide important phytochemical profiles and biological functions for the application of D. dentiger roots as a new source of natural COX-2 inhibitors and antioxidants in pharmaceutical industry.

Abstract
Lagopsis supina is a well-known traditional Chinese medicine and used as an agent for diuresis in China for centuries. This is the first time to evaluate the diuretic activity of the ethanol extract of L. supina (LS) and its four fractions (LSA, LSB, LSC, and LSD) in normal rats. After the administration of LS-H, LS-M, LSB-H, and LSC-L, the urine output of the rats was significantly increased, while the urine excretion was significantly reduced after treatment with LSB-L. The urine Na+ excretion was remarkably increased with LS-H, LS-M, LSA-H, LSA-L, LSB-H, LSC-L, and LSD-L, and the urine K+ excretion was significantly increased after administration of LS-H and LSB-H. Moreover, the urine Na+ and K+ excretion was significantly reduced after treatment with LSC-H and LSD-H. However, the urine pH values and urine and serum Na+-K+-ATPase levels did not show remarkable change after administration of LS or its four fractions in comparison with the control group. On the contrary, LS and its four fractions can suppress the renin-angiotensin-aldosterone system (RAAS), including ADH arrest by LSB-H, LSB-L, LSC-L, LSD-L, and LSD-H and ALD arrest by LSD-L, as well as promote ANP release by LS-M, LSB-H, LSC-H, and LSD-H, while furosemide can suppress only arrest of ADH within 24 h compared with the control group. In addition, LS and its four fractions did not change the urine and serum TNF-α and IL-6 levels in normal rats within 24 h. This study will provide a quantitative basis for explaining the natural medicinal use of LS as a diuretic agent for edema and promoting the diuretic process.
