Using a modified method for alleviation of base line hump and short acquisition time, aluminum-27 nuclear magnetic resonance studies were carried out on the accumulated aluminum in intact plant tissue. Hydrangea sepals and leaves of 3 species of the family Theaceae gave aluminum signals at 10-20ppm. This implies that the forms of aluminum are hexacoordinated complexes. The spin lattice relaxation times were 0.4-1.0ms. The spectra showed that both hydrangea sepals and tea leaves contained more than two forms of aluminum.
