A new method is proposed to extract the axes of tubular vortices in complex fluid flows. Loci of sectional local minimum of the pressure associated with the advection acceleration are traced numerically. It is applied to a homoge-neous isotropic turbulence to demonstrate that swirling motions actually exist around these axes. The present method is shown to be superior to several typical ones commonly used in identifying tubular vortices
