Paratrimerins G and H, two prenylated phenolic compounds from the stems of Paramignya trimera

摘要

From the stems of Paramignya trimera (Rutaceae), two new prenylated phenolic compounds, paratrimerins G (1) and H (2), together with 24 known compounds, as well as their alpha-glucosidase inhibitory activity was examined. Paratrimerins G (1) and H (2) showed moderate inhibitory effect, with the IC50 values of 89.2 and 58.8 mu M, respectively. The plausible biosynthetic pathways of two new compounds was proposed.
