Popis: | The chemical composition of the leaf oils of five Malaysian Piper species (P. aduncum L., P. lanatum Roxb., P. pedicellosum Wall., P. penangense C. DC. and P. betle L.) was determined by co-chromatography with authentic samples on two columns of different polarity, GC-MS and Kovats retention indices. Dillapiole at 64.5% was the most abundant component in the oil of P. aduncum. Chavibetol constituted 69.0% and 42.7% of the oils of P. betle and P. lanatum, respectively. The major components of the oil of P. pedicellosum were β-phellandrene (21.9%) and eugenol (17.2%). (E)-Nerolidol (17.5%) and cedrol (14.8%) were found to be the major constituents of P. penangense |
