Try running a report. From the Report Center Create a new report. Select the report type 'Search Query Performance'. Make your criteria selection and create the report. In the report is a column called 'Search Query'. Caution: Google only shows you some of the search phrases that triggered your Ad and reports the rest as like '5 other unique queries'. Google also only reports the information where a user clicked on your ad. I think you may be also able to get some information using the webmaster tools that google provide. However I have yet to confirm this. Hope this helps.
