| description | Natural product has been increasingly popular among the consumers, people starts to look for alternative
from these natural products than continuing using the synthetic products especially for medicinal or
domestic appliances. The objectives of this study were, first to determine the amount of extractives present
in the bark of R. apiculata and R. mucronata using methanol as the solvent, and second was to determine
the toxicity of the bark extracts against pathogenic microorganisms through series of bioassay tests at
different concentration. For the study on the antifungal properties, bioassay was performed on Fusarium
oxysporum and Aspergillus niger using agar dilution method while paper disc diffusion method was
performed on Candida albicans. The minimal inhibition concentration for the tested fungi was 1 % for agar
dilution method and for C. albicans, 0.01 % of the extracted crude. Screening on the antibacterial
properties of the methanol extract, paper disc diffusion method was used on E. coli and S. aureus at
different concentration. Among the two extracts, R. mucronata showed higher potential with antifungal and
antibacterial than compared with bark extract from R. apiculata however after performing a two way
ANOVA, it was revealed that there was no significant different on the antibacterial properties between the
two studied species. |
