The present study was aimed for the evaluation of analgesic, anti-diarrheal and anti-depressant activities of methanol crude extract of Bridelia verrucosa leaves in Swiss albino mice. The analgesic activity was assessed by formalin-induced paw licking method, where the crude extract of B. verrucosa (400 mg/kg, b.w.) exhibited 54.55% reduction of licking response in mice as compared to 69.09% reduction exhibited by standard acetylsalicylic acid. In the castor oil-induced diarrhea in mice, the plant extract at the dose of 400 mg/kg, b.w., demonstrated 57.67% reduction of diarrheal feces in mice. The antidepressant activity of the plant extract was evaluated through phenobarbitone-Na induced sleeping time test. The methanol extract of B. verrucosa and its different Kupchan fractions were also subjected to screenings for membrane stabilizing and cytotoxic activities using acetylsalicylic acid and vincristine sulphate as standard, respectively.

Albizia lebbeck (Linn.) Benth. is a deciduous tree which is planted as ornamental and avenue tree almost all over Bangladesh. Leaves of the plant are used in ethnomedicine for the treatment of convulsion and CNS related disorder. This study was aimed to evaluate the neuropharmacological effects of the methanol extract of A. lebbeck leaves in Swiss albino mice. The locomotor effect of crude methanol extract of the plant was investigated by open field and hole cross tests while the anxiolytic activity was determined using elevated plus-maze (EPM) and light/dark box (LDB) tests. Furthermore, the sedative activity of the plant extract was assessed by sodium thiopental-induced sleeping time test. The results demonstrated that the methanol extract significantly (p < 0.001) reduced locomotion of the animals in both hole cross and open field tests in dose-dependent manner at 200-400 mg/kg b.w. In both EPM and LDB tests, the plant extract produced significant anxiolytic effect (p < 0.05) at the doses of 100-400 mg/kg b.w. In addition, it showed significant (p < 0.001) dose-dependent decrease in the onset of sleep and an increase in duration of sleep in sodium thiopental-induced sleeping time test. Preliminary phytochemical analyses of the plant extract revealed the presence of alkaloid, flavonoid, glycoside, saponin, tannin and resin. In acute toxicity test, the leaf extract did not exhibit any adverse effect in mice during 7 days treatment. The results of the present studies suggest that the crude methanol extract of A. lebbeck leaves possesses significant CNS depressant, anxiolytic and sedative properties and rationalize the traditional uses of the plant.Bangladesh Pharmaceutical Journal 21(2): 80-86, 2018

Wrigthia arborea (Dennst.) Mabb., locally known as Shet-kurchi, is a small deciduous tree. These species are important in the traditional healthcare, especially in menstrual and renal complaints. The present study was designed to investigate the antidiarheal and antidiabetic activities of methanol extract of W. arborea. The methanol extract was studied for antidiarrhoeal properties using castor oil and magnesium sulphate induced diarrhoeal model in mice. At the doses of 100 and 200 mg/kg body weight, the extract reduced the frequency and severity of diarrhea in test animals throughout the study period. Antidiabetic effect was also evaluated in normal and alloxan induced diabetic rats. Considerable drop of elevated blood glucose level was observed in the normoglycemic and alloxan induced diabetic rats at a dose of 150 and 300 mg/kg b.w. when the extract was given intraperitoneally. Altogether, these results suggest that the methanol extract could be used for treating diarrhea and diabetes. This is the first report of antidiarheal and antidiabetic potential of W. arborea.

Plants are the priceless sources of bioactive natural compounds. Medicinal plants have been used since time immemorial in both developing and developed countries. Flemingia macrophylla (Willd.) is widely used as a hereditary medicines. The current study was designed to observe the analgesic, antidiarrheal and CNS depressant activities of methanol extract of the leaves of F. macrophylla (MEFM) and its petroleum ether (PEFM), dichloromethane (DFM), chloroform (CFM) and aqueous (AFM) fractions. The analgesic activities was assessed by acetic acid induced writhing method at doses 200- and 400- mg/kg body weight. The CNS-depressant effect was assayed by phenobarbitone sodium-induced sleeping time test. The anti-diarrheal activity of the extract was evaluated using castor oil-induced diarrhea in mice. The crude extract displayed significant peripheral analgesic activity at both test doses with 56.72- to 59.70-% inhibition of writhing responses, respectively. In CNS-depressant test, the extract revealed its activity in a dose dependent manner. In screening for antidiarrheal activity, the extract exhibited 20.83 and 41.67 % inhibition of defecation at 200- and 400-mg/kg bw, respectively whereas the standard loperamide (50 mg/kg bw) displayed 70.83 % inhibition of defecation.

In this present study, the leaf extracts of Parmentiera cereifera were subjected to a comparative evaluation of the antioxidant capacities, phenol and polyphenols content, membrane stabilization, thrombolytic, antimicrobial activities and cytotoxicity to brine shrimps (Artemia salina). When the DPPH (1,1- Diphenyl-2-picryl hydrazyl) radical scavenging effect was determined spectrophotometrically significant radical scavenging property was observed in crude methanol extract (ME) with IC50 of 21.95 ?g/ml. Here, butylated hydroxytoluene (BHT) and ascorbic acid (ASA) were used as standard antioxidants. The phenol and polyphenol content of the extractives varied between 56.84 to 89.58 mg of GAE/gm of dried extract. The thrombolytic and membrane stabilizing activities were assessed by using human erythrocyte and the results were compared with standard streptokinase (SK) and standard anti-inflammatory drug, acetyl salicylic acid (ASA), respectively. The extracts demonstrated significant toxicity to A. salina with LC50 values ranging from 6.07 to 7.83 ?g/ml as compared to standard Vincristine sulphate (VS, LC50 value 0.45 ?g/ml). On the other hand, the chloroform soluble fraction (CSF) of methanol extract revealed moderate antibacterial activity against some microorganisms used in the screening. Preliminary phytochemical investigation suggested the presence of flavonoids, saponins, tannins, triterpenoids and steroids.

The paper details a biological investigation on chukrasia tabularis and aglaia roxburghiana, species of meliaceae. The methanol crude extract of chukrasia tabularis and aglaia roxburghiana have been screened for antitumor potentials using brine shrimp lethality bioassay with ten different concentrations. An established cytotoxic agent vincristine sulphate has been used to compare the results. From the graphs the concentration of methanolic crude extract yields the value of LC50 (50% mortality) as 1.58mg/ml and 2.21mg/ml for chukrasia tabularis and aglaia roxburghiana, respectively. In the same way the concentration at which 90% mortality (LC90) occurs for the methanol extract are obtained from the graphs and the values have been found to be 141.41mg/ml and 70.70mg/ml for chukrasia tabularis and aglaia roxburghiana, respectively.

The present study was aimed to isolate and investigate actinomycetes having antimicrobial and cytotoxic activities from soil samples of Mirzapur, Rajshahi, Bangladesh. Total 27 bacteria were isolated and initial screening found that Streptomyces species have low to moderate antagonistic property against various pathogenic bacteria and among them EFAI-1was quite interesting. The antimicrobial activity of crude ethyl acetate extract obtained from EFAI-1was determined using broth-dilution method against Bacillus cereus, Listeria monocytogenes, Staphylococcus aureus, Escherichia coli, Shigella sonnei and Salmonella typhi. The crude extract was almost equally active against both Gram-positive and Gramnegative bacteria. The highest zone of inhibition was found 21 mm at a concentration of 100 μg/disc against Salmonella typhi. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of the crude extract against the test bacteria were in the range of 15.6-125 μg/ml and 62.5-250μg/ml, respectively. We found that the LC50 value of the crude extract was only 0.13 μg/ml against brine-shrimp nauplii indicating its potent cytotoxic nature. Our results indicate that this bacterium would be an excellent source of potent antibiotic and anticancer drugs.Bangladesh Pharmaceutical Journal 20(2): 188-193, 2017
