Chemical constituents of the bark oils of Goniothalamus SPP / Wong Mui Hung
Chemical constituents of bark oils from Goniothalamus ridleyi, Goniothalamus uvarioides and Goniothalamus velutinus have been studied. The stem bark of G. uvarioides (1.50 %) composed of highest percentage of essential oil compared to the stem bark of G. ridleyi (0.7-0.8 %) and G. velutinus (0.19 %)...
