Abstract

Several native Indonesia plants have been used to prepare traditional medicine since long time ago. One of common diseases in tropical country is diarrhea, it caused by the infection of enteropathogenic bacteria such as Enteropathogenic Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Shigella sp. Belilik (Brucea javanica (L.) Merr) and Benta (Wikstroemia androsaemofolia Decne) are herbals that utilized as medicine for diarrhea in Bangka Belitung, Indonesia. Parts of these plants are mostly can be utilized as medicine, such as leaf, root, and fruit. The aims of this study were to investigate the antibacterial activity of ethanol crude extract of B. javanica (root and fruit) and W. androsaemofolia (leaf and fruit) against enteropathogenic bacteria (EPEC, P. aeruginoa, S. aureus, Shigella sp.). Meth od that used was papper disc diffusion. The results showed that at concentration 10 mg/mL, 20 mg/mL, and 30 mg/mL of B. javanica ethanol extract of both root and fruit could not inhibit the enteropathogenic bacteria, while the ethanol extract of leaf and fruit of W. androsaemofolia were shown inhibition activity on the growth of enteropathogenic bacte ria. W. androsaemofolia leaf extract performed the best inhibition activity to the growth of EPEC (20.55±1.5mm) and S. aureus (22.14±4.5mm), it was better than kanamycin performance at the same concentration (30 mg/mL). In addition, ethanol extract of W. androsaemofolia fruit showed the best inhibition activity against Shigella sp. (19.64±1.8mm).

Abstract

Screening of anti-malaria compound from nature is one of important thing to cure malaria disease especially in Bangka Belitung province. One of plant that as used as traditional medicine to cure malaria is Belilik (Brucea javanica (L.)Merr. The aim of this study was to investigate the present of some kind of biochemical compound, and to evaluate in vitro anti-malaria activity of ethanol extracts of Bruce javanica fruits and roots against Plasmodium falciparum. A visual method was allowed to evaluate the in vitro anti-malaria activity of the extracts against P. falciparum. The number of parasites per 5,000 erythrocytes on thin Giemsa stained smears was calculated microscopically. IC50 values were determined by probit analysis of SPSS 13 program. The result showed, that the ethanol extract of Belilik contained some biochemical compound such as alkaloid, flavonoid and phenol in fruits and alkaloid, phenol and saponin in roots. The anti-malaria activity of ethanol extracts of Brucea javanica fruits and roots on P. falciparum were very effective as IC50<0,01 μg/mL. The highest inhibition of 100 μg/mL of Brucea javanica fruits and roots were 5.95% and 16.99% respectively. Brucea javanica could inhibit Plasmodium falciparum in vitro with very small dosage of extract and very potential to develop as malaria medicine.
