The FTSEurofirst 300 was down 0.1 per cent at 910.90 points at 10:24 BST, with declines among energy firms contributing to the slide.
Shares in oil giant BP dipped by 1.4 per cent after the company revealed that the weakening cost of the commodity has resulted in a fall in second-quarter profits.
Climbs among pharmaceutical companies helped to limit the slide on the benchmark index, with GlaxoSmithKline, Roche and Sanofi-Aventis rising by up to 2.3 per cent.
Market strategist Joshua Raymond explained that there were "mixed reactions" on the stock market following the release of the BP figures.
News that costs had been reduced initially sent its share price higher, however headlines focusing on profits being halved prompted many investors to sell off their shares.
"Volumes are a little lighter than usual and the investors that have been long for the last few weeks have started to close up positions," Mr Raymond added.
