Two new hydrolyzable tannins, nobotanins J and K, were isolated by a combination of column chromatography and centrifugal partition chromatography from the leaf extract of Heterocentron roseum, and shown to have trimeric and tetrameric structures composed of combinations of the common monomeric units, casuarictin and pterocarinin C, on the basis of spectral and chemical evidence.

The structure of nobotanin B, a dimeric ellagitannin of Tibouchina semidecandra, has been revised to 9 on the basis of structural analysis of a partial hydrolysate.
