Abstract

Mangrove forests are commonly found in tropical and subtropical areas located on the border of land and sea. They act as physical barrier to lessen the effects of coastal disasters and rich with many plant species. Plant species that dominantly covers mangrove areas are important due to the presence of extractives. The objectives for this study were firstly to determine the amount of dichloromethane (DCM) and methanol (MeOH) crude extracts from R. apiculata and R. mucronata bark. Secondly, to assess antifungal properties of MeOH bark extracts. Thirdly, to identify the chemical constituents of DCM and MeOH bark extracts from R. apiculata and R. mucronata bark. Sequential solvent extraction by using DCM and MeOH were carried out. Gas chromatography-mass spectrometry techniques were used to identify and characterize the chemical constituents and compositions of DCM and MeOH crude extract from R. apiculata and R. mucronata bark. The antifungal activities were determined in methanol extracts using agar dilution method. The total DCM bark extract of R. apiculata and R. mucronata were 0.021% and 0.026%, respectively. Methanol crude extract from R. apiculata and R. mucronata were 7.83% and 5.65%, respectively. For DCM crude extract, urs-12-ene (35.81%) and olean12-ene (21.07%) were the major compounds detected. The major chemical constituents in MeOH crude extract from R. mucronata were 2- propenoic acid (31.23%), 1, 2-benzenedicarboxylic acid (22.37%) and mono (2- ethylhexyl) phthalate (13.11%). MeOH crude extract from R. apiculata and R. mucronata were toxic to Chaetomium globosum and Gloeophyllum trabeum.
