ABSTRACT Different classes of known alkaloid compounds were identified for the first time in leaves and barks of Ficus benjamina L. from Moraceae family. The identification of 28 alkaloids in F. benjamina leaves and 14 alkaloids in its barks was identified using chromatographic analysis as Gas Chromatography associated to Mass Spectrometry (GC-MS). This characterization analysis allows to verifying the presence of different alkaloids type-classes in both leaves and barks, such as isoquinoline class, indole class and quinolizidine class. The quantification results are deduced by analysis with spectrophotometric assay, using a calibration curve of boldine as standard alkaloid that reveals the ...

ABSTRACT Synthetic insecticides are widely known to control insect pest, but due to high operational cost, environmental pollution, toxicity to humans, harmful effect on non-target organisms and the development of insect resistance to this products, have created the need for developing alternative such as those involving the use of botanical pesticides to control insect pest. Bioactive compounds d...
