Abstract |
The first investigation of Phyllanthus mirabilis Müll.Arg. led to the isolation of six undescribed compounds
including two tyramine derivatives: phyllatyramines A and B; three butenolide analogues, phyllantenolide,
phyllantenocoside-O-gallate and epi-phyllantenocoside-O-gallate; and a flavanonol gallate, (− )-taxifolin-3-Ogallate; as well as two first isolated natural products, phyllatyramine C and phyllantenocoside; together with
twenty-three known compounds. Their structures were elucidated by spectroscopic means. ECD spectra of all
isolated butenolides were compared and assigned the configurations. Phyllatyramine A displayed weak cytotoxicity against the KB cell line, while phyllatyramines B and C showed weak cytotoxicity against KB and HeLa
cell lines. In addition, phyllatyramine B and (− )-taxifolin-3-O-gallate showed more potent α-glucosidase inhibitory activity than the standard acarbose 3.4 and 5.8 fold, respectively. |
