The present study was undertaken to determine the potential anti-secretory and spasmolytic mechanism ofCrinum jaguswater/ethanol extract (25, 50 and 100 mg/kg, po). Anti-secretory activities were evaluated using castor oil and PGE2-induced enteropooling models in rats. Spasmolytic activities were conducted on small intestinal transit, on carbachol, 5-HT-induced intestine motility as well as on naloxone-pretreated intestine transit.C.jagusextract 25, 50 and 100 mg/kg bw has significantly (p<0.01) reduced in dose-dependent manner the castor oil-induced intestine secretion with inhibition rate of-59.7, -78.7 and-78.2% respectively.C jagus25, 50 and 100 mg/kg bw water/ethanol extract induced significant (p< 0.01) dose-dependent reduction of PGE2-induced fluid accumulation, with inhibition rate of-16.9, -57.7 and-66.2% respectively. On intestine transit, as on carbachol and on serotonin-induced intestine motility, the extract significantly (P< 0.01) reduced the distance covered by the charcoal. The spasmolytic effect ofC jagusextract was inhibited by the naloxone. These findings show thatC jagusmay reduce intestine secretion by the blockage of prostaglandins receptors. The spasmolytic effect could result from the blockage of muscarinic and/or serotonergic receptors, and by involving opiate receptors. These results support the traditional use ofC jagusin gastrointestinal disorders treatment.

Steamed roots of Rehmannia glutinosa (R. glutinosa) have been traditionally used in Oriental medicine for the treatment of auditory diseases such as tinnitus and hearing loss. To investigate whether the ethanol extract of steamed roots of R. glutinosa (SRG) increases activity of antioxidant enzymes and the level of glutathione (GSH), we measured activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), and glutathione reductase (GR) and GSH level in HEI-OC1 cells after treatment with 5–50 μg/ml of SRG. The SOD and CAT activities were significantly increased in the presence of SRG compared to the control group. Maximal activities of SOD and CAT were observed in these cells exposed to 10 μg/ml of SRG. The GPX activity also increased dramatically in response to the treatment with SRG in a dose-dependent manner. The GR activity was only increased in the presence of 50 μg/ml of SRG compared to the control group. The level of GSH gradually increased in the presence of 5–50 μg/ml of SRG. In the cytotoxicity test, 5–50 μg/ml of SRG did not show any significant cytotoxicity. These results suggest that the traditional use of R. glutinosa for the treatment of auditory diseases may be explained, in part, by activation of intracellular antioxidant enzyme systems. Further studies are necessary to clarify the active constituents of SRG responsible for such biomolecular activities.

The article deals with the history of the study and the current state of research of physiological and biochemical properties of the plant genus Sedum that are useful for human and has been used in folk medicine for many years. It was noticed that antioxidant properties of extracts from plants S. sarmentosum, S. sempervivoides, S. takesimense were caused by the presence of phenolic compounds. Methanol extract of plants S. takesimense exhibited strong scavenging activities against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals as well as significant inhibitory effects on lipid peroxidation and low density lipoprotein (LDL) oxidation induced by a metal ion Cu2+. Various immunomodulatory activities of various fractions of plants extracts (S. dendroideum, S. kamtschaticum, S. sarmentosum, S. telephium) are observed. It was shown that the ethanol extract of S. sarmentosum and it’s fractions suppressed specific antibody and cellular responses to ovalbumin in mice. The methanol extract of plants S. sarmentosum reduced the levels of anti-inflammatory markers, such as volume of exudates, number of polymorphonuclear leukocytes, suppressed nitric oxide synthesis in activated macrophages via suppressed induction of inducible nitric oxide synthase (iNOS). Polysaccharides fractions from plants S. telephium inducing productions of tumor necrosis factor alpha (TNF-α), increasing the intensity of phagocytosis in vitro and in vivo. Methanol extract from the whole part of S. kamtschaticum strongly inhibit PGE2 production from lipopolysaccharide-induced RAW 264.7 cells, a mouse macrophage cell line via modulating activity in gene expression of the enzyme cyclooxygenase-2 (COX-2). The methanol extract of plants S. sarmentosum and the major kaempferol glycosides from S. dendroideum have antinociceptive activity. It was noticed that anti-adipogenic activity of extracts from plants S. kamtschaticum were caused by inhibition of peroxisome-proliferator-activated receptor γ (PPARγ) expression and it’s dependent target genes, such as genes encoding adipocyte protein 2 (аР2), lipoprotein lipase (LPL), adiponectin and CD36. Polysaccharides fractions from S. telephium cause inhibition of cell adhesion of human fibroblast (MRC5) to laminin and fibronectin via interfere with integrin-mediated cell behaviour and they contributed to the role of polysaccharides in cell-matrix interaction. The methanol extract of plants S. sarmentosum exhibited a significant inhibitory activity in the chick embryo chorioallantoic membrane angiogenesis in a dose-dependent manner. The crude alkaloid fraction of S. sarmentosum caused a dose-dependent inhibition of cell proliferation on murine hepatoma cell line BNL CL.2 and human hepatoma cell line HepG2 without necrosis or apoptosis. Alkaloids from plants S. sarmentosum may improve survival of hepatoma patients via the inhibition of excessive growth of tumor cells. Plant’s juices have antiviral activity (S. sarmentosum, S. spurium, S. stahlii). Crude ethanol extract S. praealtum have spermicidal activity of the in mice and a relevant inhibitory effect of aqueous extract on human spermatozoa motility as well as an anti-fertilizing activity in rats. Hepatoprotective triterpenes, e.g., δ-amyrone, 3-epi-δ-amyrin, δ-amyrin and sarmentolin were isolated from S. sarmentosum. 2- and 2,6-substituted piperidine alkaloids (e.g., norsedamine, allosedridine, sedamine, allosedamine) are observed in plants S. acre, which in the presence of data on the use of pyridine and piperidine derivatives for treating neurodegenerative diseases (e.g., Alzheimer's disease), points on the promising research in this area. Taking into account that biologically active compounds are accumulated in the aboveground vegetative organs of plants of Sedum, the prospects of further study of the use of Sedum for the purposes of biotechnology and in the pharmaceutical industry becomes apparent. This work extends the existing views regarding the use of plants Sedum.

Aims. To observe the effects of Guizhi Fuling Capsule (GZFLC) drug serum on uterine leiomyoma cells and explore its mechanism. Main Methods. Sixty Sprague Dawley rats were randomly divided into two groups (normal saline lavage group and GZFLC lavage group), then, respectively, blank serum and GZFLC drug serum were collected, and finally human uterine leiomyoma cells were treated. Human leiomyoma tissues were collected from 20 patients who underwent uterine leiomyomas operations, and leiomyoma cells were primary cultured. The leiomyoma cells were treated by GZFLC drug serum in different concentrations (10%, 20%, and 30%) and variable treatment time (12 h, 24 h, 36 h, 48 h, and 72 h). Cell proliferation was observed using CCK8 assay. Flow cytometry and Annexin V/PI were used to assay the effects of GZFLC drug serum on cell apoptosis. Western blot analysis was used to assay the effects of GZFLC drug serum on TSC2, FOXO, and 14-3-3γ expression in uterine leiomyoma cells. Key Findings. In the concentrations of 10%~30%, GZFLC drug serum could inhibit proliferation of leiomyoma cells in dose-dependent manner; at the time of 36 h, cell inhibition rate was at the peak; GZFLC drug serum could induce apoptosis of leiomyoma also in a dose-dependent manner, and apoptosis rate quickly achieved maximum at 12 h time points, and then second apoptosis peak appeared at 36 h. Compared to nontreatment group, TSC2, FOXO, and 14-3-3γ expressions in drug serum group were significantly changed after 12 h treatment. Significance. GZFLC drug serum can efficiently inhibit the proliferation and induce apoptosis of leiomyoma cells, which is related to the 14-3-3γ pathway.

Aim: This study was designed to assess the antibiofilm activity of quercetin on characterized S. aureus isolates. Methodology: This study evaluated 36 S. aureus isolates, each of which was identified using Gram staining, culture, biochemical, and PCR assays. Isolates were cultured and their biofilm production was evaluated using Congo red agar (CRA) plates, microtiter plate tests and PCR, and the effects of quercetin were examined. Results: The CRA results revealed that eight (22.3%) S. aureus isolates were strongly positive for biofilm production and an additional 18 isolates (50%) showed moderate biofilm capacity. The remaining 10 isolates were negative (27.7%) for biofilm production. S. aureus isolates were divided into strong positive, intermediate, and negative groups, 27.8%, 44.5%, and 27.7%, respectively. Scanning electron microscopy showed that the biofilm-producing isolates appeared as aggregates of cells within a heavy matrix. In addition, PCR assay identified IcaA and IcaD (66.6% for both) biofilm production genes in most isolates and IcaC (61.1%), IcaB, FnbB (33.3% for both), and Fib (22.2%) in several other strains. Quercetin significantly inhibited biofilm activity in biofilm producing S. aureus isolates in a dose-dependent manner, with an inhibition rate of 29.6-87.7%. Interpretation: Biofilm production is dependent on Ica gene phenotype and strains with an IcaABCD or IcaABD phenotype produce more biofilm than strains with IcaAD phenotype. Quercetin significantly inhibited S. aureus biofilm production, irrespective of Ica phenotype.

Abstract Present study is involved in identification of biophenolic and flavonoids from the aqueous-ethanol extract of Cyperus iria and appraisal of inflammatory and stress markers involved in endocrine dysfunction based upon its folktale use. Significantly higher quantities of phenolic (82.79 ± 0.003 mg/g GAE) and flavonoid (13.61 ± 0.002 mg/g QE) contents were present. Inhibitory concentration (IC50) exhibited an excellent potential for both antioxidant (IC50 = 3.22 µg/mL) and alpha amylase (IC50 = 36.29 µg/mL) inhibitory assays. High performance liquid chromatography (HPLC), confirmed the existence of myercetin, quercetin, kaempferol and ferullic acid. Cyperus iria aqueous-ethanol extract exhibits good tolerance against glucose. Streptozotocin induced hyperglycemia declined along with improvement in inflammatory (TNF-α = 15.6 ± 0.2 g/l, COX-2 = 357 ± 0.396 U/l, IL-6 = 572 ± 0.99 pg/l) and oxidative stress markers (SOD = 163 ± 0.616 and GSH-ST = 95.8 ± 0.44 U/mL) along with biochemical parameters in a dose-dependent manner. Present study suggests that Cyperus iria aqueous-ethanol extract possess hypoglycemic potential which might be attributed to the presence of phenolics and flavonoids.

Senegalia rugata (Lam.) Britton & Rose, Synonym: Acacia concinna (Wild.) DC., Family: Fabaceae is one of the ayurvedic medicinal plant and commonly known as shikakai. The pods of S. rugata are normally used for cleansing of hair naturally due to the presence of higher content of saponins. In this study, we have isolated six compounds consisting of epigallocatechin (monomeric proanthocyanidin) from ethanol extract of S. rugata and a mixture of methyl esters of five polyunsaturated fatty acids (PUFA): methyl oleate, glyceryl trilinoleate, methyl linoleate methyl eicosenoate and methyl vernolate from petroleum ether extract of S rugata. The structures of the six compounds were elucidated using 1HNMR, 13CNMR and IR spectral studies. Epigallocatechin has shown significant in vitro anti-inflammatory property in a dose-dependent manner using the HRBC membrane stabilization method.

Glinus oppositifoliusis a small herb, widely used in the traditional medicine of Bangladesh in treatment of a variety of diseases and disorders such as insomnia, pain, inflammation, jaundice, and fever. The present study evaluated the sedative and anxiolytic potentials of the ethanol extract of leaves ofG. oppositifolius(EEGO) in different behavioral models in mice. The sedative activity of EEGO was investigated using hole cross, open field, rotarod, and thiopental sodium- (TS-) induced sleeping time determination tests, where the elevated plus maze (EPM) and light-dark box (LDB) exploration tests were employed to justify the anxiolytic potentials in mice at the doses of 50, 100, and 200 mg/kg. The results demonstrated that EEGO significantly inhibited the exploratory behavior of the animals both in hole cross and in open field tests in a dose-dependent manner. It also decreased motor coordination and modified TS-mediated hypnosis in mice. In addition, EEGO showed anxiolytic potential by increasing the number and time of entries in the open arm of EPM, which is further strengthened by increase in total time spent in the light part of LDB. Therefore, this study suggests the sedative and anxiolytic properties of the leaves ofG. oppositifoliusand supports the traditional use of this plant in treatment of different psychiatric disorders including insomnia.
