Characterisation of allelochemical compounds in Rhizophora apiculata and Acrostichum aureum of mangrove forest species

Rhizophora apiculata and Acrostichum aureum are a common mangrove species in Malaysia. Allelochemical interaction of the mangrove species was speculated to play an important role in the dominance in a harsh environment. This study assessed the quantitative and qualitative determination for total phe...

Two types of maceration extraction; water extraction and sequential alkaline extract were used for allelochemical screening analysis.
