Abstract

Fourteen volatile components including eight allypyrocatechol analgos were isolated and identified from the essential oil and ether soluble fraction of PhilippinePiper betle leaves (Piperaceae). The major constituents of PhilippinePiper betle oil were chavibetol and chavibetol acetate. Capillary GC analysis of the oil showed chavibetol (53.1%), chavibetol acetate (15.5%), caryophyllene (3.79%), allypyroacatechol diacetate (0.71%), campene (0.48%), chavibetol methyl ether (=methyl eugenol, 0.48%), eugenol (0.32%), α-pinene (0.21%), β-pinene (0.21%), α-limonene (0,14%), safrole (0.11%), 1,8-cineol (0.04%), and allylpyrocatechol monoacetate. The major component of the ether soluble fraction was allylpyrocatechol (2.38% of the leaves).
