This disease affects about one billion people worldwide and is responsible for more than 70% of cardiovascular related deaths. Recently, the World Health Organization reported that of the hypertensive cases detected in Congo, only 7% were controlled. Today, there is no lifetime treatment and existing drugs are less accessible by the African population. To treat the disease, the Congolese population uses more the medicinal plants. However, the majority of compounds responsible for the biological activity of these plants are not known. In order to bring out Congolese plants with antihypertensive properties, we focus our interest on <em>Trema orientalis</em> Blume (Canabaceae).</p> <p>An ethanolic extract of the leaves of <em>Trema orientalis</em> was prepared after successive depletion of the organic solvents. Thereafter, a bio-guided fractionation on silica gel of the ethanol extract was carried out. Fractionation monitoring was done by TLC and the results of vasodilating activity measured. The fractions exhibiting the best biological activity allowed a second fractionation process to obtain five fractions which are characteristic of polyphenols, in particular flavonoids, and which exhibited good vasodilating activity on the isolated aorta of rats. Our future work will focus on the identification of these biologically active compounds.</p> Bonazaba Milandou Longin Justin Clair, Nkounkou Loumpangou Célestine, Carreyre Hélène, Bescond Jocelyn, Vandebrouck Clarisse, Etou Ossibi Arnaud Wilfrid, Moutsambote Jean-Marie, Ouamba Jean-Maurille, Thibaudeau Sébastien, Abena Ange Antoine ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30181 Mon, 30 Dec 2019 00:00:00 +0000 Synthesis and Characterization of Indium Tin Oxide with Neem Extract for Antioxidant Applications http://journalejmp.com/index.php/EJMP/article/view/30182 <p>Indium tin oxide was prepared by using simple co precipitation method with Neem extract as reducing agent and it was characterized by using X-ray diffractometer, with the applications of antioxidant effect, the prepared sample was directly calcined at 400ºC and then characterized.

The medicinal plants of <em>Curculigo</em><em>orchioides </em>Gaertn., and <em>Oleo diox Roxb</em><em>.</em>&nbsp; collected from Western Ghat region of Kodagu, Karnataka, India have many medicinal values such as antioxidant, anti-cancer, anti-diabetic,&nbsp; neuroprotective activity and anti-inflammatory property. Aim of the study was to check whether <em>C. </em><em>orchioides </em>Gaertn. and <em>Oleo diox Roxb</em>. fractions significantly inhibit acetylcholinesterase in different concentration-dependent manner(1-3 mg/mL).</p> <p><strong>Results: </strong>Plant fraction concentrations resulted in &gt;60%AChE inhibition as compared with the standard Galantamine. The IC<sub>50</sub> value was 0.15 mg/mL which was calculated from the equation of the percentage inhibition curve for the test or plant fraction. The Lineweaver-Burk plot indicated that the fraction followed competitive and non-competitive inhibition kinetics. Finally, we conclude that the type of plot exhibited by the <em>C. </em><em>orchioides </em>Gaertn. and <em>Oleo dioxRoxb. fractions </em>has a possible therapeutic application for improving memory and other cognitive functions.The medicinal plant-based drugs are known to have limitations due to their fewer side effects and problems associated with bioavailability, which necessitates the interest in finding better AChE inhibitors from plant sources.</p> G.

However, during cultivation, harvesting, transportation, handling fruits get contaminated with pathogenic microorganisms which leads to severe problems to community. Owning to this point, in current research, bacteriological analysis was performed on Sofeda, Pineapple, Grape, Banana, Apple, Orange, Guava, papaya, Jujube and Starfruit. Total 50 samples were randomly collected from market and street vendors of Dhaka city. Higher numbers of rotten fruits were present in wholesale markets. 35 strains were isolated which included <em>Salmonella</em> spp., <em>Acinetobacter</em> spp., <em>Klebsiella</em> spp., <em>Vibrio cholerae</em>, <em>Vibrio parahaemolyticus</em>, <em>Staphylocoous aureus </em>and <em>E. coli.</em> They were identified using biochemical test and antibiogram for selective isolates. In case of drug resistance of isolates, majority exhibited resistance against Erythromycin, Vancomycin and Amoxycillin and showing sensitivity against Ciprofloxacin and Ceftriaxone. It was observed in the current study that 100% isolates were resistant against Erythromycin, followed by Amoxycillin 90.63% and vancomycin 86.25%, where only 35.27% isolates were resistant against Ciprofloxacin. In case of sensitivity 64.73% isolates were sensitive against Ciprofloxacin followed by Ceftriaxone 66.25%.&nbsp;</p> Mahmuda Akhter Akhi, Avijit Banik, Oshin Ghurnee, Nantu Chandra Das, Showmitro Nondi, Maruf Abony ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30190 Thu, 16 Jan 2020 00:00:00 +0000 Genome Status of Lippia alba Polyploid Complex Long-term in vitro Cultivated http://journalejmp.com/index.php/EJMP/article/view/30191 <p>This study is the first report of a genetic stability analysis of a polyploid complex maintained <em>in vitro</em> for a long-time. Twenty-two accessions of <em>Lippia alba</em>, a medicinal species of economic importance, had been maintained under <em>in vitro</em> culture conditions for 7 years through sprouting of axillary buds. Four clones of each accession were analyzed, being three plants from <em>in vitro</em> bank and one cultivated in the field. We investigated the genetic stability of diploid, aneuploid, triploid, tetraploid, and hexaploid accessions. The investigation was carried out using flow cytometry, inter simple sequence repeat (ISSR) and simple sequence repeat (SSR) markers. No significant variation in nuclear DNA content was observed between the <em>in vitro</em> conserved plants and their respective field plant. Out of 23 ISSR primers screened, 8 primers were found to produce clear reproducible bands resulting in a total of 5456 bands. 86.36% of the analyzed plantlets (19 accessions) showed at least one polymorphic band. The polymorphic rate ranged from 1.61 to 33.87%. The SSR markers were used to confirm the absence or low occurrence of variation in accessions that showed no polymorphism or polymorphism for only one ISSR primer. The genetic instability detected in our study at the molecular level may be attributed to the natural instability of <em>L. alba</em> genome combined with the long-time <em>in vitro</em> maintenance.</p> Sirlei A.

In this investigation, we synthesize AgNPs using the aqueous solution of the leaf extract of 4 indigenous plant samples such as –<em>Abroma augusta</em>, <em>Barringtonia acutangula</em>, <em>Dillenia indica </em>&amp;<em> Eupatorium odoratum</em> in room temperature (35±2°C). After that, formation of AgNPs were confirmed by UV-VIS spectrum, the answered (435, 445, 430 &amp; 440 nm), respectively. The average size of the AgNPs also confirmed by Particle size analyser (PAS), the <em>B. acutangular</em> species showed the best quality of silver nanoparticles among the other plant extracts. FTIR analysis showed that five biomolecule groups like phenols, aromatic, alkyne, alkane and alkene were found in among these plant samples. Our findings suggest that the seed germination percentage, relative seed germination rate, relative shoot &amp; root growth and germination index of the tested plant depends upon concentration gradient of synthesize AgNPs. At 0.6 mg/ml concentration, the tested plant samples give the best favorable growth condition.</p> Sk Md Abu Imam Saadi, Amal Kumar Mondal ##submission.copyrightStatement## http://journalejmp.com/index.php/EJMP/article/view/30192 Sat, 18 Jan 2020 00:00:00 +0000
