Mortality Effect

Background. Toxoplasmosis is a zoonosis disease that can cause a variety range of manifestations in human specially fetus duration and immunodeficiency conditions. Due to toxicity and side effects of current treatment, we evaluated in vivo and in vitro effects of ethyl acetate extract of Acorus calamus rhizomes (rootstocks) on Toxoplasma gondii. Methods. The plant, Acorus calamus, was collected from Sari, North of Iran in spring season. Ethyl acetate extract was provided from plant rhizomes using Soxhlet apparatus. The total phenolic and flavonoid contents of the extract were measured by the Folin–Ciocalteu method. The mortality effect of different concentrations (1-256 μg/ml) of the extract on Toxoplasma tachyzoites was assessed by flowcytometry and propidium iodide staining. For the therapeutic effect assessment, the tachyzoites were inoculated intraperitoneally to mice, and then these mice were orally and intraperitoneally administered different concentrations (32, 64, 128, and 256 mg/kg) of the extract. Also, an infected group received PBS including DMSO 1% as negative control, and an infected group administered sulfadiazine as positive control. For toxicity evaluation of this extract, a group only received dose 256 mg/kg. Results. The plant extract was rich of phenolic compounds ( 41.27 ± 0.21   mg / g ), whereas it contained fewer amounts of flavonoids ( 4.79 ± 0.01   mg / g ). Results of in vitro experiments showed that there is an inverse relationship between the concentrations and the mortality of the parasites ( I C 50 = 200.01 ± 7.74   μ g / ml ). The highest percentage (62%) of dead tachyzoites was seen at maximum concentration of the extract. A significant longevity (8.9 days) was belonged to mice orally administered extract dose (256 mg/kg/day).Conclusion. The ethyl acetate extract of A. calamus rhizomes had significant anti-Toxoplasma activities either in vitro or in vivo. It may be connected to high amount of phenolic compounds. We suggest that the effects of different fractions and the admin types of the extract will be evaluated on the parasite.

This study aims to evaluate the bioactive components, in vitro bioactivities, and in vivo hypoglycemic effect of P. frutescens leaf, which is a traditional medicine-food homology plant. P. frutescens methanol crude extract and its fractions (petroleum ether, chloroform, ethyl acetate, n-butanol fractions, and aqueous phase residue) were prepared by ultrasound-enzyme assisted extraction and liquid–liquid extraction. Among the samples, the ethyl acetate fraction possessed the high total phenolic (440.48 μg GAE/mg DE) and flavonoid content (455.22 μg RE/mg DE), the best antioxidant activity (the DPPH radical, ABTS radical, and superoxide anion scavenging activity, and ferric reducing antioxidant power were 1.71, 1.14, 2.40, 1.29, and 2.4 times higher than that of control Vc, respectively), the most powerful α-glucosidase inhibitory ability with the IC50 value of 190.03 μg/mL which was 2.2-folds higher than control acarbose, the strongest proliferative inhibitory ability against MCF-7 and HepG2 cell with the IC50 values of 37.92 and 13.43 μg/mL, which were considerable with control cisplatin, as well as certain inhibition abilities on acetylcholinesterase and tyrosinase. HPLC analysis showed that the luteolin, rosmarinic acid, rutin, and catechin were the dominant components of the ethyl acetate fraction. Animal experiments further demonstrated that the ethyl acetate fraction could significantly decrease the serum glucose level, food, and water intake of streptozotocin-induced diabetic SD rats, increase the body weight, modulate their serum levels of TC, TG, HDL-C, and LDL-C, improve the histopathology and glycogen accumulation in liver and intestinal tissue. Taken together, P. frutescens leaf exhibits excellent hypoglycemic activity in vitro and in vivo, and could be exploited as a source of natural antidiabetic agent.

Inflammatory Effect

In this study, we aimed at evaluating in vitro and in vivo anti-inflammatory activity of various extracts of the rhizomes of Globba pendula Roxb. Three extracts ( n-hexane, ethyl acetate, and water) were screened for their inhibitory effect on NO production by lipopolysaccharide-stimulated RAW 264.7 macrophages. The ethyl acetate extract of G. pendula rhizomes (EGP) showed a potential effect with an IC50 value of 32.45 µg/mL. For in vivo study, the ethyl acetate extract was further investigated for its anti-inflammatory effect using collagen antibody-induced arthritic mice (CAIA). The level of arthritis in experimental mice significantly reduced ( P < .05) after treatment with EGP at a dose of 500 mg/kg body weight (b.w.). This study also revealed that EGP is orally non-toxic. Ethyl p-methoxy cinamate was identified as the main constituent of EGP, which may result in its anti-inflammatory effect.

Background. Malaria is one of the most critical diseases causing about 219 million cases worldwide in developing countries. The spread and development of resistance against chemical antimalarial drugs is one of the major problems associated with malaria control. The present study was to investigate the antimalarial efficacy of ethyl acetate extract and one fraction of Bidens pilosa in vivo in order to support the usage of this plant by traditional healers to treat malaria. Methods. The extracts were prepared by maceration of B. pilosa leaf powder in ethyl acetate. The liquid filtrate of the extract and the best in vitro antiplasmodial fraction using HPLC were concentrated and evaporated using a rotavapor under vacuum to dryness. The antimalarial activity of B. pilosa plant products were evaluated in vivo against Plasmodium berghei infected mice according to the Peter and Rane test. The antimalarial efficacy of the a selected crude extract (ethyl acetate extract) was evaluated at 125, 250, and 500 mg/kg, while a selected fraction from ethyl acetate extract (fraction 12) was evaluated at 62.5 and 125 mg/kg. Blood from experimental animals was collected to assess hematological parameters. Results. The crude extract of ethyl acetate and fraction 12 demonstrated 100% in vivo parasite suppressive activity at doses of 500 mg/kg and 125 mg/kg, respectively, for the crude extract and fraction 12. The mice treated with 250 and 500 mg/kg had their parasitemia (intraerythrocytic phase of P. Berghei) drop considerably, disappearing by the 8th day in mice receiving 500 mg/kg. The ethyl acetate extract of B. pilosa, fraction 12 showed an even higher antiplasmodial activity. By the 5th day of the experiment, the treatment led to a modification of hematological parameters in mice. The chloroquine (5 mg/kg), fraction 12 (125 mg/kg), and the crude extract (500 mg/kg) groups all survived the 30 days of the experiment, while the negative control group registered 100% of the deaths. Conclusion. This study scientifically supports the use of Bidens pilosa leaves in the traditional treatment of malaria. However, the mode of action and in vivo toxicity of the plant still need to be assessed.

Various solvent extracts of Phymatopteris hastata, a traditional Chinese medicinal material, were screened for their antioxidant activities. Four systems of in vitro testing were employed to investigate the antiradical and antioxidant effect, i.e., the 2,2-diphenyl-1-picryhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) systems, the hydroxyl radical scavenging assay and the reducing power. In addition, butylated hydroxytoluene (BHT), a widely used synthetic antioxidant, was also studied for comparison. The results revealed that the ethyl acetate extract exhibited outstanding antioxidant activities, which was close or even superior to BHT. Furthermore, the total phenolic (TP) and total flavonoid (TF) contents of different extracts were measured, expressed as gallic acid and rutin equivalent, respectively. The antioxidant activities and the TP/TF content of different extracts followed the same order: ethyl acetate extract > butyl alcohol extract > petroleum ether extract, showing a good correlation between the antioxidant activities and the TP/TF content. The results showed that these extracts, especially the ethyl acetate extract, were rich in phenolics and flavonoids and could be considered as natural antioxidants.

Water lily (Nymphaeaceae antares) contains a vast array of phenolic compounds with important natural antioxidative properties that could inhibit the adverse effects of the reactive oxygen species produced in living things. These substances are complex in composition which requires a suitable extraction medium to exploit the phenolic compounds. This study was designed to determine the antioxidative properties in petal and stamen of water lily extracted using different extraction solvents namely ethyl acetate and 60% methanol. Antioxidant properties of the samples were determined using 2,2-diphenyl -1-picrylhydrazyl (DPPH) radical scavenging activity, ferric thiocyanate (FTC) method, thiobarbituric acid (TBA) test, total phenolic content (TPC), total flavonoid content (TFC) and total tannin content (TTC) along with individual flavonoids content using High Performance Liquid Chromatography (HPLC). The yield of extract was found to be the highest in petals extracted with 60% methanol (44.55±1.63%) while stamen extracted with ethyl acetate yielded the lowest (24.50±1.09%). In the DPPH inhibition method, petal extracted with ethyl acetate obtained the highest scavenging activity (89.15±3.62%). FTC analysis revealed that ethyl acetate extract of petal experienced the highest percentage inhibition (76.70±6.48%) while in TBA analysis ethyl acetate extract of stamen exhibited the highest percentage inhibition (70.78±1.39%). Flavonoids such as quercetin, kaempferol, rutin, gallic acid, catechin, epigallocatechin, p-coumaric acid and myricetin were found to be present in ethyl acetate and 60% methanol extracts of water lilies stamen and petal. The information from this study indicates that water lily petals and stamens may be integrated as a good source of nutrients in the food industry, the pharmaceutical industry. If the advantages of water lily are not used and integrated into everyday life for health benefits, it will be a massive waste of natural resources.

Polyphenols from berries have proved healthy effects after“in vitro”and“in vivo”studies, such as preventing tumor growing and neurodegenerative and cardiovascular diseases. We compared four different kinds of berries—strawberry, raspberry, blackberry, and blueberry—with the aim to distinguish their phenolic composition, concerning their antioxidant capacity along with their“in vitro”availability. Folin-Ciocalteu method was used for the determination of phenolic compounds, and the antioxidant capacity was measured by ORAC method. Moreover, the determination of anthocyanins was accomplished with an HPLC-DAD. Finally, we carried out an“in vitro”digestion to simulate the gastrointestinal digestion. All berries showed good antioxidant capacity with significant differences, besides high total phenolic compounds. Content of anthocyanins measured by HPLC-DAD varied between the different berries, namely, blackberries and strawberries which showed higher anthocyanin concentration. After“in vitro”digestion, berries showed poor bioavailability of the analysis of anthocyanins (9.9%–31.7%). Availability of total phenolic compounds was higher than anthocyanins (33%–73%). Moreover, strawberries and blackberries presented the less availability grade. Decrease in antioxidant activity measured by ORAC method was about 90% in all berries studied. Therefore, bioavailability of phenolic compounds remains unclear and more correlation between“in vitro”and“in vivo”studies seems to be necessary.

Abstract Background Begonia barbata Wall is an important medicinal plant in Bangladesh used to treat several human diseases. The intention of the existing work was to determine in vitro and in vivo pharmacological properties of petroleum-ether, dichloromethane, and ethyl acetate soluble fractions of methanol extract of B. barbata whole plant (MEBB). The total phenolic content (TPC) was determined by Folin-Ciocalteu test while antioxidant activity assay was performed by DPPH radical quenching process. Tail immersion and acetic acid-induced writhing methods were utilized to evaluate analgesic effect in albino mice. To evaluate the hypoglycemic potential, glucose tolerance test is used. Castor oil-induced diarrhea method is utilized to figure out the anti-diarrheal action in mice. Thiopental-sodium-induced sleeping time test was exploited for the appraisal of CNS antidepressant action. Results Antioxidant activities of the test materials followed the order: dichloromethane fraction (DCMF) > ethyl acetate fraction (EAF) > petroleum-ether fraction (PEF). The EAF yielded maximum amount of phenolic compounds (12.47 mg of GAE/g of sample). The DMF was most effective in terms of thrombolytic activity while the EAF protected the membrane integrity of erythrocyte by 63.47% inhibition of hemolysis induced by heat. Among all fractions, the PEF (400 mg/kg body weight) demonstrated highest analgesic activity in both tail immersion test (maximum elongations as 262.053%) and acetic acid-induced writhing method (66.02% writhing inhibition). During anti-diarrheal test, the plant samples significantly diminished the frequency of diarrheal episodes in mice. Similarly, the plant samples decreased the sleeping duration induced by thiopental sodium. Conclusion The above outcome exposed that B. barbata possesses significant pharmacological potential, which validates its use in Bangladesh folk medicinal practices.
