Table 2.

Comparison of different extraction methods (organic-solvent extraction (OSE), hot-water extraction (HWE), and microwave-assisted extraction (MAE)). The results are expressed as mean ± standard deviation (n = 3).

Extraction method TPC (mg GAE/g) DPPH (mg TE/g) CUPRAC (mg TE/g)
OSE 3.68 ± 0.55b* 4.16 ± 0.88c 8.04 ± 1.08c
HWT 11.29 ± 0.12a 8.87 ± 0.03a 19.51 ± 0.63a
MAE 11.23 ± 1.05a 7.19 ± 0.24b 15.43 ± 0.56b
