Description Not Available
The marine red alga Laurencia brandenii collected from the southwest coast
of India (Indian Ocean) was extracted and fractioned using column chromatography. The
individual fractions were evaluated in vitro via antimicrobial activity against six species
of Microbial Type Culture Collection and three species of clinical human pathogens,
antipest activity on Sitophilus oryzae, maggoticidal activity against 2nd instar larvae of
Sarcophaga sp. and termiticidal activity against Microtermes obesi. It was found that the
fraction eluted using petroleum ether:chloroform (6:4) exhibited broader biological activities.
The phyco-constituents of the active fraction were identified by gas chromatography-
-mass spectrometry (GC-MS) analysis. The GC-MS profile of the active fraction revealed
that the main constituent was octadecadienoic acid (49.75%) followed by n-hexadecanoic
acid (14.24%), which might have a functional role in the biological activities. The overall
activity profile envisages that these bioactive compounds from L. brandenii could be utilized
as a renewable natural resource for the development of novel environmental-compatible
formulations for the control of human pathogens, pests, termites and maggots.
