“…The main peak in the chromatogram (peak 18) was identified as agrimoniin, consistent with earlier findings (29,30). The fragmentation also matches sanguiin H-6, which has similar subunit composition and molecular weight ( Figure 2) (31), but the compound was identified as agrimoniin according to the previous identification, which was based on coelution with an authentic standard (29,30). Peaks 9 and 19 gave a similar doubly charged molecular ion at m/z 934 and fragment ions as agrimoniin, and therefore one of these two compounds may be akin to sanguiin H-6 or another tetrameric ET.…”

“…2C). They showed an [MÀH] À ion at m/z 1869, an MS 2 ion at m/z 935 (loss of HHDP) and MS 3 ions at m/z 433 and 301, data which is in concordance with HPLC-MS data reports (Aaby et al, 2007;Okuda et al, 1992) and the MS data of a major compound detected in red strawberry leaves (Hukkanen et al, 2007;Oertel et al, 2001). Peak 29 detected in leaves was tentatively identified as sanguiin H-6 ( which is consistent with previously published data for a compound detected in red strawberry (Seeram et al, 2006) and blackberry species (Mertz et al, 2007).…”

“…A grande diversidade de estruturas dos compostos tânicos que são encontradas em plantas com reconhecidas atividades terapêu-ticas, associada a sua capacidade de complexação com diferentes compostos, torna o trabalho de elucidação estrutural difícil 54 . Apesar de várias pesquisas realizadas sob diferentes abordagens com teores de taninos, a associação dessas informações com o aproveitamento de plantas medicinais é escassa.…”
