Medicinal plants contain bioactive compounds that have the potentials to cure many human ailments without unnecessary side effects like most of the chemotherapeutic drugs used today. Therefore, the need for phytochemicals in medicinal plants for potentials application in the treatments of these human ailments as alternatives. Drug resistance parasite has rendered most of the drugs used in treating many human diseases ineffective. There is an urgent need and continuous search for new drugs from natural sources because most of the drugs used are either derived from plant or end-product of the natural source. Antibacterial and antiplasmodial activities of Boswellia dalzielii stem bark chloroform extract against some pathogens and P. bergei was investigated using the serial dilution method. Phytochemical studies (GC-MS RT profiling) revealed the presence of some secondary metabolites. The extract was tested against thirteen bacterial strains (Styphylococcus epidermidis, Mycobacterium smegmatis, Enterococcus faecalis, Styplococcus aureus, Bacillus subtilis) and Gram-negative strains Klebsiella aerugninosa, Proteus vulgaris, K. pneumonia, Klebsiella oxytoca,Entrobacter cloacae, Peptostreptococcus asaccharolyticus, Escherichia coli, Proteus mirabilis). Minimum Inhibitory Concentration (MIC) and the Minimum Bactericidal Concentration (MBC) of the extract showed activities against Mycobacterium smegmatis,Escherichia coli, Klebsiella oxytoca, Klebsiella aerugninosa and Proteus vulgaris. The extract demonstrated high safety with LD50 value greater than 5000 mg/kg body weight. The extract shows a high potent of antiplasmodial activities with P. bargie inhibition of 66.95\%. The results demonstrated that Boswelliadalzielii stem bark extract can be used as a source of cheaper, less toxic novel antibiotic and antimalarial substances for drug development.

Introduction: This research main goal is to study the antiplasmodial activity of Macaranga gigantea leaf ethanolic extract and its major components on malaria parasites using ex vivo model. Methods: This study was conducted by extraction of M. gigantea leaves using ethanol and isolation of its major constituent. The extract and isolate were tested ex vivo on Balb-C mice{\textquoteright}s blood after i.p. administration of Plasmodium berghei strain ANKA. Antiplasmodial activity was observed from mice blood treated by various concentration of either extract or isolate and the parasitaemia percentage were determined by calculating infected blood cell after 24 h of the treatment. It is expressed as decreased of parasitaemia levels and percent of inhibition. Qualitative analysis of active fraction were tested by HPLC method. Chemical structure of isolate were characterized by using UV, IR, 1H-NMR, 13C-NMR and MS spectrophotometry. Results: Ex vivo antiplasmodial study gave the percent inhibition as much as 92.1; 85.7; 64.1; 41.5 and 21.7\% at extract concentrations of 300, 100, 30, 10 and 3 μg/ mL respectively. The IC50 values of the extract was 27.1 μg/ml. With respect to the percent of inhibition, at the same concentration, the isolate showed activity as much as 70.2; 62.5; 39.1; 21.7 and 10.8\%. The IC50 value of the isolate was 60.2 μg/ml. At the same concentration with extract and Isolate, Pyrimethamine as positive control gave percent inhibition of 94; 87.5; 44.8; 15.; and 12\%, with IC50 of 31.4 μg/ml. The results showed that major constituent of M. gigantea leaves is flavonoid. HPLC analysis using a photo diode-array detector showed that the active fraction have same retention time with that of apigenin as standard. Based on instrumental analysis data and compared with literature, a flavonoid derivate known as apigenin can be said has been isolated. Conclusion: It can be concluded that either M. gigantea leaves extract or isolated active constituent known as apigenin have potent antiplasmodial property.

Background: Malaria is infectious vector born disease affecting 212 million people belonging to 97 countries globally in the year 2016. Although this number has reduced progressively from last one decade but recent failure of currently available antimalarial drug therapy has accentuated the urgent need to explore different novel approaches in Anti-plasmodial drug discovery. Objective: The aim of the present study was to evaluate the Anti-plasmodial activity of traditional medicinal plants Ficus deltoidea and Ficus benjamina. Materials and Methods: Crude petroleum ether and hydro alcoholic extract of both the plant species were evaluated for Anti-plasmodial activity by schizont maturation inhibition assay using 3D7 plasmodium strains. Results: It was observed that petroleum ether extract of F. benjamina leaves showed most promising inhibitory effect on the growth of schizonts with IC50 14.5 \μg/ml. Bio-assay guided fractionation of petroleum ether extract of F. benjamina led to the hexane and chloroform fraction with high Anti-plasmodial activity (IC50 4.0 \μg/ml and IC50 7.8 \μg/ml respectively). Further, phytochemical investigation of F. benjamina indicated the presence of various valuable phytochemicals belonging to class of steroids, terpenoids and phytosterols. Conclusion: This study has revealed the Anti-plasmodial activity of F. deltoidea and F. benjamina for the first time. Significant Anti-plasmodial activity and preliminary phytochemical studies of F. benjamina indicates its rich chemical diversity which make this plant a good candidate for isolating new molecule that could serve as new lead in Anti-plasmodial drug discovery.\
