The Gamma-ray instruments on-board INTEGRAL offer an unique opportunity to perform time resolved analysis on GRBs .
The imager IBIS allows accurate positioning of GRBs and broad band spectral analysis , while SPI provides high resolution spectroscopy .
GRB 030501 was discovered by the INTEGRAL Burst Alert System in the ISGRI field of view .
Although the burst was fairly weak ( fluence F _ { 20 - 200 { keV } } \simeq 3.5 \times 10 ^ { -6 } erg cm ^ { -2 } ) it was possible to perform time resolved spectroscopy with a resolution of a few seconds .
The GRB shows a spectrum in the 20 - 400 keV range which is consistent with a spectral index \Gamma = -1.7 .
No emission line or spectral break was detectable in the spectrum .
Although the flux seems to be correlated with the hardness of the GRB spectrum , there is no clear soft to hard evolution seen over the duration of the burst .
The INTEGRAL data have been compared with results from the Ulysses and RHESSI experiments .
