The constituents of the oil were identified by using GC- MS and retention indices. The oils of <em>K. angustifolia </em>was found to be rich in sesquiterpenoids. The major constituents were camphor (21.1%), together with borneol, borneol formate, b- Maaliene, a-guaiene, caryophyllene oxide, vellerdiol and ledol. Essential oils of<em> K. rotunda</em> consisted of monoterpenoids (22.5%) and sesquiiterenoids (6.8%). However the major constituent was identified as an aromatic ester, benzyl benzoate (49.8%).<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/1347/ Kaempferia angustifolia Kaempferia rotunda essential oils Zingiberaceae
