Figures & data
Table 1. 1H and 13C NMR data of compounds 1–4 isolated from A. melegueta (more details in the supplementary data file).
Figure 2. α-Amylase (A) and α-glucosidase (B) inhibitions (%) of compounds isolated from A. melegueta fruit. Data are presented as mean ± SD of triplicate determinations. a–e Values with different letters presented for a given concentration for each extract are significantly different from each other.
