We present the first results of searches for axions and axion-like-particles with the XENON100 experiment .
The axion-electron coupling constant , g _ { Ae } , has been probed by exploiting the axio-electric effect in liquid xenon .
A profile likelihood analysis of 224.6 live days \times 34 kg exposure has shown no evidence for a signal .
By rejecting g _ { Ae } larger than 7.7 \times 10 ^ { -12 } ( 90 % CL ) in the solar axion search , we set the best limit to date on this coupling .
In the frame of the DFSZ and KSVZ models , we exclude QCD axions heavier than 0.3 eV/c ^ { 2 } and 80 eV/c ^ { 2 } , respectively .
For axion-like-particles , under the assumption that they constitute the whole abundance of dark matter in our galaxy , we constrain g _ { Ae } to be lower than 1 \times 10 ^ { -12 } ( 90 % CL ) for masses between 5 and 10 keV/c ^ { 2 } .
