Infection is one of the health problems and a disease that mainly causes death. Malaria is a parasitic infection that is transmitted through the Anopheles sp. The female then causes infection and besides malaria, other contaminants that caused infection are bacteria such as Escherichia coli and Staphylococcus aureus. This study aims to determine the antioxidant, antimicrobial, and antiplasmodial activity of Sonchus arvensis L. ethyl acetate fractions. In vitro antiplasmodial activity was carried out by Rieckman methods against Plasmodium falciparum strain 3D7. In vitro antioxidant activity was conducted by Prieto method against (1,1-diphenyl-2-picrylhydrazyl (DPPH). Then antimicrobial activity was performed using well diffusion method against Escherichia coli and Staphylococcus aureus. Maceration of S. arvensis L. dried leaves used n-hexane and ethyl acetate successively. Then the ethyl acetate extract was fractionated by vacuum column chromatography, using n-hexane and ethyl acetate as mobile phases. There are five fraction groups based on thin-layer chromatography (TLC) analysis. The IC50 of antioxidant and antiplasmodial activity showed that fraction IV was the lowest value and categorized as active for antioxidant (IC50=22.56 μg/mL), for antiplasmodial (IC50=12.07 μg/mL). Fraction IV also had antimicrobial activity, with diameter of inhibition zone (DIZ) of 19.22 mm against Escherichia coli and 17.167 mm against Staphylococcus aureus.

Introduction: The amaryllidaceae family is characterized by presenting alkaloids with powerful pharmacological activities, including antiprotozoal activity. The aim of the present work was to determine the chemical composition and evaluate the in vitro antiplasmodial activity of the total alkaloids of the bulbs of two amaryllidaceae species from northern Per{\'u}. Methods: The total alkaloids were extracted from the bulbs using an acid-base extraction. The chemical composition of the total alkaloids was determined by GC-MS, using galantamine as a reference standard. It was investigated the in vitro antiplasmodial activity against Plasmodium falciparum FCR-3 strain (chloroquine-resistant). Results: 8 alkaloids were identified in the bulbs of Clinanthus incarnatus: lycorine, galanthamine, galanthine, vittatine/crinine, hippamine, 3-O-acetylpowelline, 11,12-dehydroanhydrolycorine, 1-O-acetyllycorine with values of 19.73; 14.99; 10.36; 10.22; 10.16; 10.14; 10.04; 9.85 μg GAL/100 mg of total alkaloid (TA) respectively and 6 alkaloids in the bulbs of Clinanthus ruber: lycorine, anhydrolycorine, 11,12-dehydroanhydrolycorine, 2,4-didehydro-2-dehydroxylycorine, 8-0-dimethylmaritidine, hippamine, with values of 70.2; 18; 4.15; 3.45; 6.8 and 0.1 μg GAL/100 mg TA respectively. The total alkaloids of the species of C. incarnatus and C. ruber at concentrations of 1.0; 2.5; 5.0; 10.0; 25.0 and 50.0 μg/ml presented inhibition percentages of 23.5 {\textpm} 0.46\% to 94 {\textpm} 0.56\% against P. falciparum with (p \<0.05). They also presented IC50 0.375 μg/ml (C. incarnatus) and IC50 0.241 μg / ml (C. ruber). Conclusion: The main component of total alkaloids of the bulbs of two species was lycorine, in adittion, these species showed in vitro antiplasmoidal activity against Plasmodium falciparum FCR-3 strain at the doses tested.

\α--Mangostin is a widely reported group of Xanthone compounds from the Clusiaceae family of 40 genera and over 1000 species spread across the tropics and subtropics area. The Objective for determine effect of \α-mangostin from Garcinia tetrandra Pierre stem bark against development stadium inhibition and globin accumulation of Plasmodium falciparum. Inhibition stadium development assay used based on the Rosenthal method. Plasmodium falciparum parasitic globin accumulation assay. Globin accumulation assay used the highest concentration of in vitro antimalarial test using SDS-PAGE with positive control E-64 and \α-mangostin were incubated together with the malaria parasite during 24 h. Result of Inhibition stadium development of Plasmodium falciparum against \α-mangostin show inhibition from development stadium of the malaria parasite Plasmodium falciparum, Electrophoresis show globin accumulation from electrophoresis followed by staining using Coomassie brilliant blue. \α-mangostin showed inhibition the growth of malaria parasite Plasmodium falciparum with dose 10 \μg/ml is expected to occur a large accumulation of globin, which can be viewed both morphologically and by the method of SDS-PAGE.
