Sharmila Nicollet dropped two late bogeys on 16th and 18th holes to finish with a third round card of three-over 76 and slip to tied 38th at the Turkish Airlines Ladies Open.
Nicollet is now six-over 225 at the par-73 National Golf Club. She had two birdies, both on par-5s against five bogeys.
English rookie Charley Hull and Carlota Ciganda of Spain shared the lead heading into the final round.
Hull, 17, fired a four-under-par 69 for a three-round total of four-under, while Ciganda moved back into top position with a one-under 72.
Hull posted five birdies at holes one, five, 10, 13 and 14, before dropping one shot at the 18th. She has had a sensational start to her professional career this year, with ties for second in both the Lalla Meryem Cup in Morocco and South African Women's Open.
She played in the last group with the eventual winner Ariya Jutanugarn in Morocco.
Meanwhile, a bogey-free round of six under 67 put the defending champion Christel Boeljon right back in the mix as she finished just a stroke behind the leaders on three-under-par.
England's Trish Johnson held a share of the lead for much of the day but bogeyed the 14th and 18th slipping back into a share of fourth place with South African Lee-Anne Pace and Florentyna Parker of England on two-under-par.
Overnight leader Laura Davies recorded a five-over 78 and dropped back into a share of 10th.
