This research was intended to evaluate the antioxidant activities of extracts and fractions of kepel fruit pulp (KFP) based on radical scavenging capability towards 2,2′-azinobis(3-ethylbenzo thiazoline-6-sulphonic acid) diammonium salt (ABTS) and 2,2′-diphenildiphenyl-1-picrylhydrazil radical (DPPH). In this study, the radical scavenging activities were also correlated with total phenolics and flavonoid contents. Among the evaluated samples, the ethyl acetate fraction exhibited the highest antiradical antioxidant activity towards ABTS radical with IC<sub>50</sub> of 0.35 μg/ml, lower than that of vitamin C (as positive control). It also showed highest antiradical activity using DPPH based assay. Methanolic extract had total phenolic content of 58.28 ± 0.37% wt/wt gallic acid equivalent, higher than its fraction. Meanwhile the petroleum ether soluble fraction revealed flavonoid content (76.06 ± 11.9%) as rutin equivalent, among the extract and fractions evaluated. Based on coefficient (R2) values, phenolics and flavonoids contents contributed to 73.09% and 30.99%% towards antiradical scavenging activities, respectively.</p> <p>Dhaka Univ. J. Pharm.

This study was aimed to investigate the <em>in vitro </em>macrophage phagocytic activity of extracts and fractions of red dragon fruit peel (<em>Hylocereus polyrhizus</em>). The <em>in vitro </em>test was conducted based on the method of Leijh <em>et al. </em>The parameters of phagocytic activity were based on the macrophages capacity to phagocytose latex beads using the calculation of phagocytic capacity and phagocytic index. The test results indicated significant difference (p &lt; 0.05). The petroleum benzene extract showed higher phagocytic activity of macrophages than methanol extract of the fruit peel, sediment, and media control (-). The LSD test showed that macrophage phagocytic activity using fractions (500 and 100 μg/ml) was significantly different from macrophage phagocytic activity using fractions (20 μg/ml), sediment (500, 100 and 20 μg/ml), extracts (500, 100 and 20 μg/ml), and media control.</p> <p>Dhaka Univ.

Liquid chromatography was performed on HPLC system and 20μl of samples were injected into a C<sub>18</sub> column (150 x 4.6 mm i.d., 5μm particle size) and the eluents were monitored through a PDA detector at 239 nm. An isocratic method with a flow rate of 1 ml/min was used to elute the compounds with a mobile phase comprised of 70:30 v/v mixture of phosphate buffer (pH 6.8±0.2) and acetonitrile. The retention time of the compound was found to be 2.8 minutes. According to the ICH Q2(R1) guidelines, the method was validated by establishing several analytical parameters such as system suitability, specificity, linearity, accuracy, precision, limit of detection (LOD), limit of quantitation (LOQ), ruggedness and robustness to assay linagliptin. The method showed good linearity (R<sub>2</sub> = 0.9981) over the concentration ranges of 40 – 60 μg/ml with a recovery between 99.48% ± 0.38% RSD to 100.22% ± 0.011% RSD, whereas the LOD and LOQ values were 0.05 μg/ml and 0.15 μg/ml, respectively. The relative standard deviation (% RSD) for inter-day and intra-day precision was not more than 2.0%. Hence, the proposed method can be applied accurately for research and routine analysis of linagliptin in bulk as well as different pharmaceutical dosage forms.</p> <p>Dhaka Univ. J. Pharm.

A series of formulations were prepared where PEG 6000 with polymers named PVP K30, cross PVP, poloxamer 237, HPMC ASLF, pregelatinized starch, Na-CMC, Eudragit L100, and kollidon IR were used in different ratios. Among 41 formulations, solid dispersions of ibuprofen in PEG 6000 with each of PVP K30, poloxamer 237, and Na-CMC at ratio of 2:9:7 revealed improved solubility of 952.73 ± 1.31, 878.18 ± 0.97, and 1263.64 ± 1.58 μg/ml, respectively. The physicochemical properties of these preparations were ascertained by FTIR, SEM, DSC, and particle size analyses. FTIR spectrum showed absence of chemical interactions and physical compatibilities between ibuprofen and polymers were confirmed by DSC. Disappearance of individual surface properties in solid dispersions were revealed by SEM studies, which indicated the formation of effective preparations. On the other hand, particle size analysis showed reduction in particle size of ibuprofen from solid dispersions that demonstrated solubility enhancement of ibuprofen. The above studies suggested that solid dispersions of ibuprofen in PEG 6000 at ratios of 2:9:7 with each of PVP K30, poloxamer 237, and Na-CMC were found to be effective to improve aqueous solubility.</p> <p>Dhaka Univ.

However, studies of acute toxicity of <em>C. gigantea </em>root extract has not been performed.The purpose of this research was to know the safety level, the chemical constituents, and the acute toxicity of methanol extract of <em>C. gigantea </em>root bark given orally on <em>Rattus norvegicus </em>in rats. <em>C. gigantea </em>root bark was extracted by using methanol. The methanol extract was suspended in 1% sodium carboxymethyl cellulose (CMC) and administered orally by gavage (1250, 2500 and 5000 mg/kg) in separate groups. On the day of fifteen, all animals were anesthetized and some selected vital organs were excised, weighed and macroscopically examined. The liver was assessed histopathologically. There were no lethal effects, behavioral changes and no significant change in body and organ weights compared to control after the administration of the extracts. Thus, the value of LD<sub>50</sub> for oral administration of methanol extracts from root bark of <em>C. gigantea </em>was larger than 5000 mg/kg. Methanol extract of <em>C. gigantea </em>root bark must be considered safe enough as none of the rats were died along the study.

Antidiabetic activity was evaluated by oral glucose tolerance test where the crude extract of <em>S. suaveolens </em>(400 mg/kg b.w.) exhibited 56.10% reduction of blood glucose level as compared to 58.53% by standard glibenclamide (0.1 mg/kg b.w.). In the castor oil-induced diarrhea in mice, the plant extract, at the dose of 400 mg/kg b.w. demonstrated 42.11% reduction of diarrheal feces, while the standard loperamide revealed 57.89% reduction of diarrheal feces. The analgesic activity of <em>S. suaveolens </em>was assessed by both radiant heat tail-flick and acetic acid-induced writhing test. The methanolic extract and different Kupchan fractions of <em>S. suaveolens </em>were also subjected to screening for total phenolic content, DPPH free radical scavenging assay, membrane stabilizing, thrombolytic and antimicrobial activities. In the DPPH assay, the aqueous soluble fraction of methanolic extract revealed highest antioxidant properties with IC50 value of 18.99 μg/ml. The membrane stabilizing activity was assessed by hypotonic solution- and heat-induced methods and was compared with standard acetyl salicylic acid. In hypotonic solution-induced haemolysis, the hexane and carbon tetrachloride soluble fraction inhibited 54.42% and 52.67% haemolysis of RBCs, respectively. On the other hand, in heat-induced haemolysis, the chloroform soluble fraction inhibited the haemolysis of RBC by 57.10% as compared to 72.09% produced by acetyl salicylic acid. In antimicrobial assay by disc diffusion method, only the hexane and carbon tetrachloride soluble fractions demonstrated moderate antimicrobial activity (zone of inhibition = 7.0-15.0 mm) against the test organisms.</p> <p>Dhaka Univ.
