Polyphenolic constituents of three species of Melastomataceous plants have been investigated, and six novel hydrolysable tannin oligomers were isolated. (1) Two new trimeric ellagitannins, nobotanin C (4) and E (5) have been isolated from the leaf extract of Tibouchina semidecandra, and 5 was isolated also from Heterocentron roseum. Upon partial hydrolysis with hot water, nobotanin C gave six hydrolysates, five of which, 6-10, were identified with those obtained by similar treatment of nobotanin A (1) and B (3). This evidence, coupled with the spectral analysis of another hydrolysate (11), indicates structure (4) for nobotanin C. Degalloylation of nobotanin E into nobotanin C with tannase led to the structure (5) of nobotanin E. (2) Three novel dimeric ellagitannins, nobotanin G (15), H (16), I (17), and a trimer, nobotanin J (19) were isolated from the leaf extract of H. roseum. Nobotanin G was also isolated from Schizocentron elegans, together with nobotanin B. Based on the spectral analysis and chemical correlation, these four oligomers were formulated as 15, 16, 17 and 19, respectively. Nobotanin I (17) is the first example of a macrocyclic dimer possessing a depside linkage. (3) Oligomeric hydrolysable tannins isolated in this study have unique structures in which a galloyl part and biphenyl part of valoneoyl group are linked to 0-4 of a glucose core and 0-2〜0-3 or 0-4〜0-6 of the other glucose core(s), respectively. The HPLC analysis of the extracts of the other species, Medinilla magnifica, Melastoma candidum, Miconia magnifica and Dissotis erecta etc. indicates that oligomeric hydrolysable tannins of this class will be widely distributed in Melastomataceous plants.
