Abstract:Introduction: A mosquito-borne disease infected by Plasmodium is named as Malaria. Some drugs subjected to be active againts protozoans has developed resistance. It is very urgent to find alternative sources of new antimalarial agent. The main aim of this research was to study the activity of methanolic extracts of the leaf from mangrove plants on Plasmodium berghei by using ex vivo model. Method: Screening of antiplasmodial activity from methanolic leaf extracts of Sonneratia alba, Acanthus ilicifolius and So… Show more

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'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, 1 H-NMR, 13 C-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 IC 50 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 IC 50 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 IC 50 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: Cassia fistula L. has been traditionally used to cure skin diseases. That disease can be caused by various bacteria, such as Propionibacterium acnes and Pseudomonas aerugniosa. Objective: the objective of this research was to formulate cream containing active fraction of Cassia fistula bark and to study the antibacterial activity as well as physical stability of the active substance after formulation. Material and Methods: The cream base were oilin-water (O/W) and water in oil (W/O) type. Antibacterial activity test had been performed by using agar diffusion method. Determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were conducted by microdilution method. The active fraction was formulated into creams with concentration of 4-6x MIC. Physical evaluation of creams including organoleptic, pH, viscosity, TLC (Thin Layer Chromatography) profiling and antibacterial activity against both tested bacteria were evaluated during 28 days of storage. Results: The results showed that ethyl acetate fraction was the most active, having MIC and MBC values of 175 and 350 ppm respectively against P. acnes, while those against P. aeruginosa were 400 and 800 ppm. Optimation on creams using different type of cream bases showed that either O/W or W/O creams remained stable during 28 days of storage in terms of organoleptic and pH. The viscosity increased in O/W and decreased in W/O type. Qualitative analysis by TLC profiling showed that the ethyl acetate fraction of Cassia fistula as chemical compounds in creams was relatively stable as the profile remained the same after 28th day of storage. Result of antibacterial activity test on cream with O/W base was unchange after 28 day, while that with W/O revealed no activity which may due to poor diffusion within the cream base as media. Conclusion: active fraction of Cassia fistula can be formulated into cream with O/W cream base system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
