[PMID: 38921358 PMCID: PMC11204877 DOI: 10.3390/jof10060371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 05/12/2024] [Accepted: 05/14/2024] [Indexed: 06/27/2024] Open
Abstract
Alpinia oxyphylla is a traditional Chinese medicinal plant with a medicinal history of more than 1700 years. Ring leaf blight (RLB) disease, caused by pestalotioid species, is an important disease of A. oxyphylla, seriously affecting the yield and quality of its fruits. The causal agent of RLB disease has not been systematically identified or characterized yet. In this study, thirty-six pestalotioid strains were isolated from the leaves and stems of A. oxyphylla that was collected from six cities of Hainan province, China. Based on the multi-locus phylogeny (ITS, tef-1α and tub2) and morphological characteristic analyses, seventeen species belonging to three genera (Neopestalotiopsis, Pestalotiopsis and Pseudopestalotiopsis) were identified, and six new species (N. baotingensis, N. oblatespora, N. olivaceous, N. oxyphylla, N. wuzhishanensis and N. yongxunensis) were described. Pathogenicity tests revealed that strains of Neopestalotiopsis species caused more severe ring leaf blight on A. oxyphylla than strains of Pestalotiopsis and Pseudopestalotiopsis under wounded inoculation conditions.

Heliyon 2024; 10:e25337. [PMID: 38356568 PMCID: PMC10865255 DOI: 10.1016/j.heliyon.2024.e25337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 01/24/2024] [Accepted: 01/24/2024] [Indexed: 02/16/2024] Open
Abstract
Background Paraquat (PQ) is a herbicide that is used globally in the agriculture sector to eradicate unwanted weeds, however it also induces significant damages in various organs of the body such as testes. Tectochrysin (TEC) is an important flavonoid that shows versatile therapeutic potentials. Currently, there is no established antidote to cure PQ-induced testicular toxicity. Objective The present study was conducted to evaluate the ameliorative effects of TEC against PQ prompted testicular damage. Methods Sprague-Dawley rats (n = 48) were used to conduct the trial. Rats were allocated in to 4 groups i.e., Control, PQ administrated group (5 mgkg-1), PQ + TEC co-administrated group (5 mgkg-1 + 2.5 mgkg-1) and TEC only administrated group (2.5 mgkg-1). The trial was conducted for 8 weeks. The activity of anti-oxidants and the levels of MDA and ROS were determined by spectrophotometric method. Steroidogenic enzymes as well as apoptotic markers expressions were evaluated by qRT-PCR. The level of hormones and inflammatory indices was quantified by enzyme-linked immunosorbent assay. Results PQ exposure markedly (P < 0.05) disturbed the biochemical, spermatogenic and histological profile in the rats. Nevertheless, TEC treatment considerably (P < 0.05) increased CAT, GPx GSR and SOD activity, besides decreasing MDA and ROS contents. TEC administration also increased sperm viability, count and motility. 17β-HSD, 3β-HSD, StAR and Bcl-2 expressions were also increased following TEC administration. The supplementation of TEC substantially (P < 0.05) decreased Bax, Caspase-3 expression and the levels of inflammatory markers i.e., interleukin-1β (IL-1β), interleukin-6 (IL-6), nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α) and cyclooxygenase-2 (COX-2) activity. Additionally, the levels of plasma testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were increased following TEC supplementation. Furthermore, TEC supplementation considerably decreased sperm structural abnormalities and histomorphological damages of the testes. The mitigative role of TEC might be due to its anti-inflammatory, anti-apoptotic, androgenic and anti-oxidant potentials. Conclusion Taken together, it is concluded that TEC can be used as a potential candidate to treat testicular toxicity.

Mol Nutr Food Res 2024; 68:e2300283. [PMID: 37888838 DOI: 10.1002/mnfr.202300283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 08/29/2023] [Indexed: 10/28/2023]
Abstract
SCOPE Propolis has been found to decrease glucose levels and increase insulin sensitivity in type 2 diabetes. However, the active ingredient responsible for these effects and its regulating mechanism are not fully understood. METHODS AND RESULTS To address this, molecular docking screening is used to screen the effective hypoglycemic ingredient in propolis and found that tectochrysin (TEC) has a high affinity to the insulin receptor (IR), highlighting its potential for glycemic control. In vivo tests show that TEC decreases glucose levels and enhances insulin sensitivity in db/db mice. By hyperinsulinemic euglycemic clamp test, this study further finds that TEC promotes glucose uptake in adipose tissue and skeletal muscle, as well as inhibits hepatic gluconeogenesis. Moreover, it finds that TEC promotes glucose uptake and adipocytes differentiation in 3T3-L1 cells like insulin, suggesting that TEC exerts an insulin mimetic effect. Mechanistically, pharmacology inhibition of IRβ abolishes the effects of TEC on glucose uptake and the phosphorylation of IR. The study further demonstrates that TEC binds to and activates IRβ by targeting its E1077 and M1079. CONCLUSION Therefore, this study sheds light on the mechanism underlying propolis' potential for ameliorating type 2 diabetes, offering a natural food-derived compound as a promising therapeutic option.

Antidiarrheal activity of Bridelia ferruginea bark methanolic extract involves modulation ATPases in mice and inhibition of muscarinic acetylcholine receptor (M3) and prostaglandin E2 receptor 3 (EP 3) in silico. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2023; 20:757-771. [PMID: 34727589 DOI: 10.1515/jcim-2021-0240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Accepted: 10/21/2021] [Indexed: 11/15/2022]
Abstract
OBJECTIVES Diarrhea, an abnormal state in which the individual has about three or more daily bowel movements, is now considered one of the most challenging global public health problems. Using plant products, such as Bridelia ferruginea is an alternative treatment option. The objective of this study was to investigate the antidiarrheal activity of B. ferruginea bark methanolic extract (BfME) and the mechanisms involved. METHODS BfME antidiarrheal activity was evaluated in mice model of castor oil-induced diarrhea and enteropooling. To evaluate motility, gastrointestinal transit time was carried out using phenol red meal, while intestinal activities of selected ATPases were also evaluated. Furthermore, the active components in BfME were detected by GC-MS analysis, while molecular docking of the most abundant compounds with muscarinic acetylcholine receptor (M3) and prostaglandin E2 receptor 3 (EP3) were conducted. RESULTS BfME at 400 and 800 mg/kg showed antidiarrheal activity by delaying onset of diarrhea, reduced gastrointestinal transit and increased intestinal activities of Na+ K+-ATPase, Ca2+ Mg2+-ATPase and Mg2+-ATPase. Molecular docking revealed that γ-sitosterol, α-amyrin, and stigmasterol have outstanding binding affinity for M3 and EP3. CONCLUSIONS In view of these results, the observed antidiarrheal activity possibly occurs via the activation of ATPases activities and inhibition of M3 and EP3.

Abstract
Alpinia nelumboides Nob.Tanaka, T.T.K.Van & V.Hoang is the new Alpninia species discovered in Vietnam in 2023. Herein, we first hydrodistillated its pseudo-stems and rhizomes to obtain its essential oils, PS-EO and RH-EO. Their volatile compounds and total polyphenols were analysed by gas chromatography-mass spectrometry and the Folin-Ciocalteu method, respectively. Antioxidant activities were determined using four different approaches. The results showed that PS-EO and RH-EO contained 40 and 31 compounds, accounting for 99.78% and 99.45% of their compositions, respectively. The contents of polyphenols and monoterpenes in PS-EO were higher than in RH-EO. RH-EO displayed weaker scavenging activities (17.40-19.53%) than PS-EO (30.81-44.08%). PS-EO also showed higher ferric and cupric reducing powers, with EC50 values of 3.50-5.30 mg/mL smaller than RH-EO's EC50 values of 19.0-23.0 mg/mL. These results first revealed the phytochemical profile and antioxidant activities of EOs from A. nelumboides.

Abstract
Zingiber and Alpinia species (family: Zingiberaceae) are popularly used in food as spices and flavoring agents and in ethnomedicine to heal numerous diseases, including immune-related disorders. However, their ethnomedicinal uses have not been sufficiently supported by scientific investigations. Numerous studies on the modulating effects of plants and their bioactive compounds on the different steps of the immune system have been documented. This review aimed to highlight up-to-date research findings and critically analyze the modulatory effects and mechanisms of the extracts and secondary compounds of several Zingiber and Alpinia species, namely, Zingiber officinale Roscoe, Z. cassumunar Roxb., Z. zerumbet (L.) Roscoe ex Sm., Alpinia galanga Linn., A. conchigera Griff, A. katsumadai Hayata, A. oxyphylla Miq., A. officinarum Hance, A. zerumbet (Pers.) Burtt. et Smith, and A. purpurata (Viell.) K. Schum. on the immune system, particularly via the inflammation-related signaling pathways. The immunomodulating activities of the crude extracts of the plants have been reported, but the constituents contributing to the activities have mostly not been identified. Among the extracts, Z. officinale extracts were the most investigated for their in vitro, in vivo, and clinical effects on the immune system. Among the bioactive metabolites, 6-, 8-, and 10-gingerols, 6-shogaol, and zerumbone from Zingiber species and cardamomin, 1'-acetoxychavicol acetate, yakuchinone, rutin, 1,8-cineole, and lectin from Alpinia species have demonstrated strong immunomodulating effects. More experimental studies using cell and animal models of immune-related disorders are necessary to further understand the underlying mechanisms, together with elaborate preclinical pharmacokinetics, pharmacodynamics, bioavailability, and toxicity studies. Many of these extracts and secondary metabolites are potential candidates for clinical development in immunomodulating agents or functional foods to prevent and treat chronic inflammatory disorders.

Abstract
Introduction Alpinia oxyphylla Miquel (A. oxyphylla), one of the "Four Famous South Medicines" in China, is an essential understory cash crop that is planted widely in the Hainan, Guangdong, Guangxi, and Fujian provinces. Particularly, A. oxyphylla from Hainan province is highly valued as the best national product for geo-herbalism and is an important indicator of traditional Chinese medicine efficacy. However, the molecular mechanism underlying the formation of its quality remains unspecified. Methods To this end, we employed a multi-omics approach to investigate the authentic quality formation of A. oxyphylla. Results In this study, we present a high-quality chromosome-level genome assembly of A. oxyphylla, with contig N50 of 76.96 Mb and a size of approximately 2.08Gb. A total of 38,178 genes were annotated, and the long terminal repeats were found to have a high frequency of 61.70%. Phylogenetic analysis demonstrated a recent whole-genome duplication event (WGD), which occurred before A. oxyphylla's divergence from W. villosa (~14 Mya) and is shared by other species from the Zingiberaceae family (Ks, ~0.3; 4DTv, ~0.125). Further, 17 regions from four provinces were comprehensively assessed for their metabolite content, and the quality of these four regions varied significantly. Finally, genomic, metabolic, and transcriptomic analyses undertaken on these regions revealed that the content of nootkatone in Hainan was significantly different from that in other provinces. Discussion Overall, our findings provide novel insights into germplasm conservation, geo-herbalism evaluation, and functional genomic research for the medicinal plant A. oxyphylla.

Abstract
Valencene and nootkatone, two sesquiterpenes, extracted from natural sources, have great market potential with diverse applications. This paper aims to comprehensively review the recent advances in valencene and nootkatone, including source, production, physicochemical and biological properties, safety and pharmacokinetics evaluation, potential uses, and their industrial applications as well as future research directions. Microbial biosynthesis offers a promising alternative approach for sustainable production of valencene and nootkatone. Both compounds exert various beneficial activities, including antimicrobial, insecticidal, antioxidant, anti-inflammatory, anticancer, cardioprotective, neuroprotective, hepatoprotective, and nephroprotective and other activities. However, most of the studies are performed in animals and in vitro, making it difficult to give a conclusive description about their health benefits and extend their application. Hence, more attention should be paid to in vivo and long-term clinical studies in the future. Moreover, valencene and nootkatone are considered safe for consumption and show great promise in the applications of food, cosmetic, pharmaceutical, chemical, and agricultural industries.

Abstract
Diarrhea is a prevalent gastrointestinal problem associated with fatal implications. It is a huge public health concern that requires better alternatives to current drugs. This study investigated the mechanisms involved in the antidiarrheal activity of Anacardium occidentale (Ao) stem bark extract, a plant commonly used in the management of diarrhea in Nigeria. Methanolic stem bark extract of the plant was partitioned into three fractions: hexane fraction, ethyl acetate fraction (AoEF) and methanol fraction. In vitro studies on the effect of these fractions on guinea pig ileum (GPI) strips, as well as the modulatory effect of AoEF on standard agonists- and antagonists-induced GPI contraction and relaxation, revealed AoEF as the most active fraction. In vivo studies to assess the effect of AoEF on the dopaminergic, muscarinic, and serotonergic pathways were carried out using gastric emptying (GE) and gastrointestinal transit (GT) as experimental end points. AoEF was subjected to GC-MS analysis, while the identified compounds were docked with the muscarinic acetylcholine receptor M3 (CHRM3) using AutodockVina. Results indicated that AoEF inhibited GE and GT via inhibition of CHRM3. In addition, GC-MS analysis revealed the presence of 24 compounds in AoEF, while docking indicated that octadecanoic acid 2-(2-hydroxylethoxy) ethyl ester exhibited the highest binding affinity to CHRM3. This study indicated that the antidiarrheal activity of Ao is through its antimotility effect via the inhibition of the muscarinic pathway. And since none of the identified compounds exhibited higher binding affinity to CHRM3 relative to loperamide, the antimotility activity of these phytoconstituents may be via synergism. Ethyl acetate fraction of Anacardium occidentale methanolic stem bark extract inhibited guinea pig ileal muscle motility. The ethyl acetate fraction inhibited gut motility via inhibition of muscarinic acetylcholinesterase receptor. GC-MS analysis identified 24 compounds in the fraction. Molecular docking revealed that the anti-motility activity of these compounds is possibly through synergism. Anacardium occidentale extracts modulate gut motility via inhibition of muscarinic acetylcholinesterase receptor.

Abstract
This study aimed to develop a rapid, sensitive, and specific LC-tandem mass spectrometry method for the determination of nootkatone in rat plasma. α-Cyperone was chosen as the internal standard (IS). The plasma was processed using a one-step acetonitrile protein precipitation method. Chromatographic separation of nootkatone was achieved on a Phenomenex Kinetex XB-C18 column (2.10 × 50 mm, 2.6 μm) at 35°C with a mobile phase consisting of acetonitrile and water under a gradient elution at a flow rate of 0.35 mL/min. An electrospray ionization source was applied and operated in positive ion and multiple reaction monitoring modes. Nootkatone and IS were quantified using the transitions of m/z 219.200 → 163.110 and m/z 219.200 → 111.000, respectively. The calibration curves were linear over the range of 10-2000 ng/mL (r = 0.9943). The lower limit of quantification was 10 ng/mL. The intra- and inter-day precision (relative standard deviation) ranged from 2.56% to 8.41%, with the accuracy values ranging from 98.9% to 99.17% for four different concentration levels. The matrix effect and extraction recovery were within acceptable limits. The validated method was successfully applied to the pharmacokinetic study of nootkatone in rats after oral and intravenous administration at three dosages. The main pharmacokinetic parameters were calculated, showing low bioavailability of nootkatone.

Abstract
BACKGROUND Alpinia oxyphylla Miq. is an important edible and medicinal herb, and its dried fruits are widely used in traditional herbal medicine. Flavonoids are one of the main chemical compounds in A. oxyphylla; however, the genetic and molecular mechanisms of flavonoid biosynthesis are not well understood. We performed transcriptome analysis in the fruit, root, and leaf tissues of A. oxyphylla to delineate tissue-specific gene expression and metabolic pathways in this medicinal plant. RESULTS In all, 8.85, 10.10, 8.68, 6.89, and 8.51 Gb clean data were obtained for early-, middle-, and late-stage fruits, leaves, and roots, respectively. Furthermore, 50,401 unigenes were grouped into functional categories based on four databases, namely Nr (47,745 unigenes), Uniprot (49,685 unigenes), KOG (20,153 unigenes), and KEGG (27,285 unigenes). A total of 3110 differentially expressed genes (DEGs) and five distinct clusters with similar expression patterns were obtained, in which 27 unigenes encoded 13 key enzymes associated with flavonoid biosynthesis. In particular, 9 DEGs were significantly up-regulated in fruits, whereas expression of 11 DEGs were highly up-regulated in roots, compared with those in leaves. CONCLUSION The DEGs and metabolic pathway related to flavonoids biosynthesis were identified in root, leaf, and different stages of fruits from A. oxyphylla. These results provide insights into the molecular mechanism of flavonoid biosynthesis in A. oxyphylla and application of genetically engineered varieties of A. oxyphylla.

Abstract
Aging is related to the lowered overall functioning and increased risk for various age-related diseases in humans. Tectochrysin is a flavonoid compound and rich in a traditional Chinese Medicine Alpinia oxyphylla Miq., which has antioxidant, anti-inflammatory, anti-cancer, anti-bacterial, anti-diarrhea, hepatoprotective, and neuro-protective effects. Therefore, we tested if tectochrysin had an effect on aging in Caenorhabditis elegans (C. elegans). Our results showed that tectochrysin could extend the lifespan of C. elegans by up to 21.0%, delay the age-related decline of body movement, improve high temperature-stress resistance and anti-infection capacity, and protected worms against Aβ1-42-induced toxicity. Tectochrysin could not extend the lifespan of the mutants from genes daf-2, daf-16, eat-2, aak-2, skn-1, and hsf-1. Tectochrysin could increase the expression of DAF-16 regulated genes. The extension of lifespan by tectochrysin requires FOXO/DAF-16 and HSF-1. Overall, our findings suggest that tectochrysin may have a potential effect on extending lifespan and age-related diseases.

Abstract
Alpinia oxyphylla, a traditional herb, is widely used for its neuroprotective, antioxidant and memory-improving effects. However, the neuroprotective mechanisms of action of its active ingredients are unclear. In this study, we investigated the neuroprotective effects of various organic extracts of Alpinia oxyphylla on PC12 cells exposed to hydrogen peroxide-induced oxidative injury in vitro. Alpinia oxyphylla was extracted three times with 95% ethanol (representing extracts 1–3). The third 95% ethanol extract was dried and resuspended in water, and then extracted successively with petroleum ether, ethyl acetate and n-butanol (representing extracts 4–6). The cell counting kit-8 assay and microscopy were used to evaluate cell viability and observe the morphology of PC12 cells. The protective effect of the three ethanol extracts (at tested concentrations of 50, 100 and 200 µg/mL) against cytotoxicity to PC12 cells increased in a concentration-dependent manner. The ethyl acetate, petroleum ether and n-butanol extracts (each tested at 100, 150 and 200 μg/mL) had neuroprotective effects as well. The optimum effective concentration ranged from 50–200 μg/mL, and the protective effect of the ethyl acetate extract was comparatively robust. These results demonstrate that organic extracts of Alpinia oxyphylla protect PC12 cells against apoptosis induced by hydrogen peroxide. Our findings should help identify the bioactive neuroprotective components in Alpinia oxyphylla.

Abstract
Musca domestica larvae have been used clinically to cure children malnutritional stagnation and low molecular weight peptides (LMWP) of Musca domestica larvae showed more useful bioactivities. But there is no report on anti-diarrhea effects and identification of the LWMP. The purposes of this study were clarifying the anti-diarrhea effects by regulating intestinal microecology and identification of LMWP. In anti-diarrhea test, diarrhea mice were administered LMWP by oral gavage. Then rectal stool indicator bacteria were counted also the identification of rectal stool bacteria were determined by PCR-DGGE. In LMWP identification test, GFC and RP-HPLC were used to separate the peptide. Then the single polypeptide was tested by MALDI TOF and N-terminal sequence analysis. The results of anti-diarrhea showed that LMWP was effective in the inhibition diarrhea in mice. And microbial diversity indices showed that LMWP treatment group exhibited a higher number of bands. The identification test showed that LMWP had four main components (10-30KD, S1, S2, S3), and there were 5, 7 and 4 peaks in S1, S2 and S3, respectively. The the molecular weight of S2-5, S3-2 and S3-3 was 877.053D, 877.0631D and 1069.4391D, respectively. And S3-3 was determined as Chain A, Carboxypeptidase G2. So the hypothesis that intestinal microbiological regulation might be one of the potential anti-diarrhea mechanisms of Musca domestica larvae LMWP which had four main components and one of the single polypeptide was identified could be drawn.

Abstract
Background:
Alpiniae Oxyphyllae Fructus (Yizhi in Chinese) have been widely used as an
herbal medicine for the treatment of diuresis, enuresis and diarrhea in China. Many studies have deciphered
some potential underlying mechanisms for its anti-diarrheal effects. However, tissue distribution
of Yizhi constituents is warranted because pharmacological receptors are frequently located in tissues.
Moreover, it is also interesting to know about the potential correlation between behavior in drug distribution
and the observed pharmacological response. The aim of this study is to investigate tissue distribution
behaviors of Yizhi constituents after oral administration of Yizhi extract to rats, focusing on 10
active principles.
Methods:
Twenty four male Sprague Dawley rats were given orally the Yizhi extract and fourteen tissue
samples were collected after being killed by bleeding from the abdominal aorta under ether anesthesia
at different time-points. The resulting tissues were excised and homogenized. Based on our previous
reports, liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) was used to quantify
the target analytes, as well as phase II metabolites, in the various biosamples.
Results:
Almost all the targeted Yizhi active principles and some glucuronidated metabolites were
qualitatively measured in rat stomach, small intestine, large intestine, as well as liver. Nootkatone,
yakuchinone A and tectochrysin were observed in the rat brain. In other rat tissues, these analytes had
lower exposure or could not be detected. Consistently, quantitative analysis revealed that the Yizhi active
principles dominantly distributed into gastrointestinal tissues followed by liver, the overall exposure
levels ranking as follows: stomach > small intestine > large intestine > liver. Tissue concentrationtime
profiles of the test active principles in rat stomach, small intestine, and large intestine were bimodal
with two concentration peaks occurring at 0.5 and 4h after oral administration, respectively. The
exposure levels in rat kidney and bladder were quite low.
Conclusion:
The active principles of Yizhi were specially distributed into gastrointestinal tissues after
oral administration of its ethanol extract to rats. The tissue distribution behaviors partly supported its
anti-diarrheal effects from a pharmacokinetic opinion. This paper will be useful as the starting point for
studying the pharmacological activities of this traditional herb.

Abstract
ETHNOPHARMACOLOGICAL USAGES Fructus Alpiniae oxyphyllae (A. oxyphylla) is an important medicinal plant that is used not only as an edible fruit, but also as an important traditional medicine for benefiting cognitive performance and alleviating a wide spectrum of diseases. Such as; warming kidney, securing essence and arresting polyuria, as well as warming the spleen and stopping diarrhea and saliva. AIMS The purpose of this review is to provide updated, comprehensive and categorized information on the traditional uses, phytochemistry and pharmacological research of A. oxyphylla in order to explore their therapeutic potential and establish a solid foundation for directing future research. MATERIALS AND METHODS All the available information on A. oxyphylla was collected via electronic search (using Pubmed, SciFinder, Scirus, Google Scholar and Web of Science) and additionally a number of unpublished resources, (e.g. books, Ph.D. and M.Sc. dissertations, government reports). RESULTS Phytochemical research on A. oxyphylla has led to the isolation of components such as essential oils, terpenes, diarylheptanoids, flavones, nucleobases and nucleosides, steroids and others. Crude extracts, fractions and phytochemical constituents isolated from A. oxyphylla showed a wide spectrum of in vitro and in vivo pharmacological activities like neuroprotective, anti-diarrheal, anti-diuretic, anti-neoplastic, anti-oxidant, anti-inflammatory, anti-allergic, viscera protective and anti-diabetic activities. Neuroprotective, anti-cancer, anti-diarrheal and anti-diuretic effects are major areas of research conducted on A. oxyphylla. CONCLUSIONS Modern pharmacological studies have supported many traditional uses of A. oxyphylla, including nervous system, urinary system and gastrointestinal system disease. There was convincing evidence in experimental animal models in support of its neuroprotection, secure essence, reduce urination, and anti-carcinogenic effects. However, all the reported pharmacological activities were carried out at pre-clinical level and the authors urge further investigation in clinical trials about these therapeutic fields of A. oxyphylla.

Abstract
A simple and rapid ultra-performance liquid chromatography⁻tandem mass spectrometry (UPLC⁻MS/MS) coupled with a one-step liquid-liquid extraction method has been developed and validated for the simultaneous determination of two flavonoids (chrysin, tectochrysin) from Alpinia oxyphylla fruits extract in rat plasma. Plasma samples were extracted with diethyl ether and separated on an ACQUITY UPLC BEH C18 column (100 mm × 2.1 mm, 1.7 μm) using gradient elution consisting of 0.1% formic acid in water (A) and methanol (B). The multiple reaction monitoring (MRM) mode with electrospray ionization in the positive ion mode was used for detection. The linear range was 0.1 ng/mL to 50 ng/mL for chrysin and tectochrysin, respectively. The accuracy (relative error, RE%) ranged from -8.8% to 7.5% and the intra-day and inter-day precision were within 15% and had a mean extraction recovery rate of 80.3% to 86.7%. The validated method was applied to a comparative pharmacokinetic study after oral administration of Alpinia oxyphylla fruit ethanol extract between normal rats and dementia rats. The area under the curve (AUC) and peak plasma concentration (Cmax) of the two constituents were remarkably increased in dementia rats than in normal rats.

Abstract
INTRODUCTION Er Shen Wan (ESW), a traditional Chinese medicinal formula comprised of Psoraleae Fructus (Babchi seeds, from Psoralea corylifolia Linn.) and Myristicae Semen (Nutmeg, from Myristica fragrans Houtt.), is widely used to treat spleen-kidney Yang deficiency (SKYD)-induced diarrhea. Previous studies have demonstrated preliminarily that the petroleum ether extract of ESW (ESWP) exhibits significant anti-diarrheal activity. The present study aimed to evaluate the anti-diarrhea activity of ESWP and to explore the underlying mechanisms with respect to fluid metabolism in a rat model of SKYD-induced diarrhea. MATERIALS AND METHODS A high-performance liquid chromatography-diode array detector (HPLC-DAD) approach was developed and validated for qualitative and quantitative analyses of the main constituents of ESWP. SKYD model rats were established and treated with an effective dose (3.5?g/kg) of the extract for two weeks. Anti-diarrheal activity and stool properties were observed. After the experiment, the appearance and histology of the intestines were evaluated. Serum levels of neuropeptide Y (NPY) and vasoactive intestinal peptide (VIP) were also determined. Furthermore, to characterize the regulation of aquaporin-4 (AQP 4) and Na+/H+ exchanger isoform 3 (NHE 3) in the colon, quantitative real-time RT-PCR (qRT-PCR), immunohistochemistry (IHC) and Western blotting (WB) were employed to detect mRNA and protein expression levels. RESULTS In the rat models, oral ESWP administration significantly reduced the diarrhea score and the number and weight of wet stools. Jejunal and ileac histological damage was impeded, and the histology score decreased. Serum VIP levels were significantly decreased, in contrast to NPY levels. In addition, AQP 4 and NHE 3 expression levels increased significantly. CONCLUSIONS These results showed that ESWP's anti-diarrheal effect might at least partially involve the regulation of hormones intimately involved in maintaining fluid and electrolyte levels, as well as by increasing AQP 4 and NHE 3 expression levels and enhancing the absorption of Na+ and water.

Abstract
Background In Shaanxi province, China, the aqueous extract of Rubia cordifolia’s aerial part (AERCAP) is traditionally used to manage diarrhea. However, there is no scientific evidence to verify the safety and efficacy of its use. The aim of this study was to investigate the anti-diarrheal and anti-inflammatory effects of AERCAP by using a rodent model. Methods The anti-diarrheal effects were studied by senna leaf-induced diarrheal and intestinal transit experiments in mice. The anti-inflammatory activity was investigated by trinitrobenzenesulfonic acid (TNBS)-induced colonic inflammation in rats. Results The results indicated that AERCAP delayed the onset of semi-solid feces, reduced the evacuation index (EI) in senna leaf-induced diarrheal in mice, and inhibited the propulsive movement in castor oil-induced intestinal transit but not in the normal intestinal transit test. The results were compared with the standard anti-diarrheal drug loperamide. Additionally, oral treatment with AERCAP significantly decreased the macroscopic damage area, improved the microscopic structure, and reduced the malondialdehyde (MDA) content, IL-1β and TNF-α levels in colonic tissue compared with the TNBS control group in rats. Conclusions AERCAP exhibited anti-diarrheal and anti-inflammatory activities in a rodent model. The study validated the traditional use of the plant in Chinese herbal medicine as a valuable natural remedy for the treatment of diarrhea.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The fructus Alpinia oxyphylla Miq. (AOM) has been used for treating diarrhea with spleen deficiency and gastralgia for thousands of years. A number of traditional Chinese medicine formulae provide AOM as an alternative herbal treatment for diarrhea, but the scientific basis for this usage has not been well defined. AIM OF THE STUDY In this study, we tried to investigate the antidiarrheal activity and possible mechanisms of Fructus AOM, aiming to enrich our understanding to the scientific meanings and theoretical significance of Fructus AOM in clinical practice. MATERIALS AND METHODS The fructus of AOM collected from Hainan province in China were macerated in the 95% ethanol to obtain the crude 95% ethanol extract, followed by subjected to chromatographic separation over a Diaion HP20 column to obtain 90% and 50% ethanol eluted fractions. The activities of the crude extract and fractions on castor oil induced acute diarrhea, rhubarb induced chronic diarrhea, gastrointestinal transit (GIT) in mice, and contractions of isolated guinea-pig ileum were evaluated. Additionally, nitric oxide (NO), gastrointestinal peptides gastrin (GAS), motilin (MTL) and somatostatin (SS) levels that related to gastrointestinal motilities were detected to demonstrate the potential mechanisms. Ultimately, LC-MS/MS method was utilized to ensure the chemical consistency. RESULTS The 95% ethanol extract and 90% ethanol eluted fraction significantly delayed the onset time and decreased the wet faeces proportion compared with control group in the castor oil induced acute diarrhea mice. In terms of further evaluation of antidiarrheal activity, the 95% ethanol extract and 90% ethanol elution displayed significant inhibition of the intestinal propulsion at the two highest oral doses of 20 g crude drug/kg and 1g/kg. Moreover the 95% ethanol extract (10 and 20 g crude drug/kg) and 90% ethanol elution (0.5 and 1g/kg) could significantly inhibit the GIT, which was partially attributed to the increase in NO and SS levels, and the decreased MTL. In vitro spontaneous contractions of the isolated guinea pig ileum induced by carbachol, neostigmine and histamine were attenuated by both the extract and elution. Phytochemical analysis of 95% ethanol extract and its fractions identified the presence of diphenylheptanes, sesquiterpenes, and flavones as the major components. CONCLUSIONS Our in vivo and in vitro data could partly support and justify the traditional usage of Fructus AOM on the treatment of diarrhea in traditional medicine.

Abstract
Background Excessive bone resorption by osteoclasts causes pathological bone destruction, seen in various bone diseases. There is accumulating evidence that certain herbal extracts have beneficial effects on bone metabolism. The fruits of Alpinia oxyphylla has been traditionally used for the treatment of diarrhea and enuresis. In this study, we investigated the effects of water extract of the fruits of Alpinia oxyphylla (WEAO) on osteoclast differentiation and osteoclast-mediated bone destruction. Methods For osteoclast differentiation assay, mouse bone marrow-derived macrophages (BMMs) were cultured in the presence of RANKL and M-CSF. RANKL signaling pathways and gene expression of transcription factors regulating osteoclast differentiation were investigated by real-time PCR and Western blotting. A constitutively active form of NFATc1 was retrovirally transduced into BMMs. Bone resorbing activity of mature osteoclast was examined on a plate coated with an inorganic crystalline calcium phosphate. The in vivo effect against bone destruction was assessed in a murine model of RANKL-induced osteoporosis by micro-computed tomography and bone metabolism marker analyses. Results WEAO dose-dependently inhibited RANKL-induced osteoclast differentiation from BMMs by targeting the early stages of osteoclast differentiation. WEAO inhibited RANKL-induced expression of NFATc1, the master regulator of osteoclast differentiation. Overexpression of a constitutively active form of NFATc1 blunted the inhibitory effect of WEAO on osteoclast differentiation, suggesting that NFATc1 is a critical target of the inhibitory action of WEAO. WEAO inhibited RANKL-induced expression of c-Fos, an upstream activator of NFATc1, by suppressing the classical NF-κB signaling pathway. WEAO also inhibited RANKL-induced down-regulation of Id2 and MafB, negative regulators of NFATc1. WEAO does not directly affect bone resorbing activity of mature osteoclasts. In accordance with the in vitro results, WEAO attenuated RANKL-induced bone destruction in mice by inhibiting osteoclast differentiation. Conclusions This study demonstrates that WEAO exhibits a protective effect against bone loss by inhibiting RANKL-induced osteoclast differentiation. These findings suggest that WEAO might be useful for the prevention and treatment of bone diseases associated with excessive bone resorption.

Abstract
Plant secondary metabolites are known to not only play a key role in the adaptation of plants to their environment, but also represent an important source of active pharmaceuticals. Alpinia oxyphylla capsular fruits, made up of seeds and pericarps, are commonly used in traditional East Asian medicines. In clinical utilization of these capsular fruits, inconsistent processing approaches (i.e., hulling pericarps or not) are employed, with the potential of leading to differential pharmacological effects. Therefore, an important question arises whether the content levels of pharmacologically active chemicals between the seeds and pericarps of A. oxyphylla are comparable. Nine secondary metabolites present in A. oxyphylla capsular fruits, including flavonoids (e.g., tectochrysin, izalpinin, chrysin, apigenin-4',7-dimethylether and kaempferide), diarylheptanoids (e.g., yakuchinone A and B and oxyphyllacinol) and sesquiterpenes (e.g., nootkatone), were regarded as representative constituents with putative pharmacological activities. This work aimed to investigate the abundance of the nine constituents in the seeds and pericarps of A. oxyphylla. Thirteen batches of A. oxyphylla capsular fruits were gathered from different production regions. Accordingly, an ultra-fast high performance liquid chromatography/quadrupole tandem mass spectrometry (UFLC-MS/MS) method was developed and validated. We found that: (1) the nine secondary metabolites were differentially concentrated in seeds and fruit capsules; (2) nootkatone is predominantly distributed in the seeds; in contrast, the flavonoids and diarylheptanoids are mainly deposited in the capsules; and (3) the content levels of the nine secondary metabolites occurring in the capsules varied greatly among different production regions, although the nootkatone levels in the seeds were comparable among production regions. These results are helpful to evaluating and elucidating pharmacological activities of A. oxyphylla capsular fruits. Additionally, it may be of interest to elucidate the mechanisms involved in the distinct accumulation profiles of these secondary metabolites between seeds and pericarps.
