Abstract
Two hydrolysable tannins, nobotanin O and nobotanin P, were isolated from t he leaf extract of Tibouchina multiflora (Melastomataceae) and their dimeri c and tetrameric structures elucidated on the basis of spectral data and ch emical correlations with nobotanin B and K, respectively. Thirteen known hy drolysable tannins including nobotanins A, B, C and J, which are oligomers characteristic of the Melastomataceae, were also isolated. (C)1999 Elsevier Science Ltd.
