Essential oil profile and biological activities of piper species
Essential oil profiling had been done by using GC-FID. The essential oil has been extracted using hydro distillation methods and their chemical compositions were analysed are Piper I01lgamentum, Piper umbel/atum, Piper aduncum, Piper caninum and Piper arborescen. The important compounds in Piper lon...
