Ulster had to settle for third place at the senior inter-provincial tournament which concluded in Dublin yesterday.
Ulster's 1-1 draw with Leinster in their final game wasn't enough after Munster had beaten Connacht earlier in the day.
Stephen Watt's side needed to beat the hosts by three clear goals to force a penalty shoot-out play-off with Munster.
But it seldom looked likely and Ulster's fine record in the competition in recent years was ended.
Ulster Elks' Rachel King grabbed the goal in yesterday's game.
Ultimately an unexpected 5-0 defeat by Munster on Friday night proved to be Ulster's undoing.
Going into the opening game Ulster hadn't lost an inter-pro for six years but a nightmare first half left them with a mountain to climb although they did well in beating Connacht 6-0 on Saturday.
Coach Watt was left to rue the earlier result.
"It was a better performance against Connacht but it's just unfortunate that a very poor opening 25 minutes of the tournament cost us," he commented.
Ulster responded in style against the western province as first half goals from Stephanie Quinn, Jessica Lynch and Jayne Clarke put them 3-0 up at the break. Further goals from Quinn, Scarlett Holdsworth and Hannah McMillan wrapped up victory.
There was double disappointment for Ulster as they failed to lift the junior inter-provincial crown yesterday in Dublin. Ulster beat Munster 2-1 on Saturday and drew 0-0 with Connacht yesterday before a 1-1 draw with Leinster which secured the trophy for the hosts.
