Table 1.

Relative abundances (%) of compounds present in the essential oil (EO), petroleum ether extract (PEE), and dichloromethane extract (DCME) of P. uviferum heartwood. RT indicates retention time (min), RI_C indicates the calculated retention index, and RI_L indicates retention index from literature [26], MS indicates the mass spectrometry, and * indicates the relative abundances of the EO compounds (extracted from [18]).
