An electroless plating method was applied to deposit Au onto the walls of pores of polycarbonate membranes. The diameter of the Au-nanotubule is about 10 nm. The characteristics of rutin transportation through the nanotubule membranes were investigated. The complex formed by rutin and Al^3＋ was transported effectively through the gold nanotubule membrane modified with p-aminothiophenol under the existence of an electric field. The method was verified by separation and determination of rutin from the rutin tablets successfully with a recovery of 96.3%～99.3%.

Key words: gold nanotubules, rutin, separation, detection
