Figure 1. The HPLC chromatogram of LSPC, MPPC, and CFPC at 280 nm.
Figure 2. The MS spectra of procyanidins in LS, MP, and CF.
Table 1. The procyanidin compounds in lotus seedpod, mangosteen pericarp and camellia flower identified by HPLC−QTOF-MS.[Citation26–Citation30]
Table 2. The antioxidant activities of LSPC, MPPC, and CFPC.
Figure 3. Effects of LSPC, MPPC, and CFPC at different concentrations on HUVECs. Control group meant cells without treatment of procyanidins, and the experimental groups were treated with LSPC, MPPC, and CFPC at 10, 50, 100, 200, 400, and 800 μg/mL, respectively. The values were expressed as means ± SD (n = 3). Different letters indicate significant difference by ANOVA, p < 0.05.
Figure 4. Effects of LSPC, MPPC, and CFPC on cell viability in H2O2 injured HUVECs. The results were expressed as percentage of control, and each value represents mean ± SD of three independent experiments. Control group meant cells without treatment of procyanidins. H2O2 group meant cells treated with 150 μM H2O2 for 8 h. The experimental groups were treated with 150 μM H2O2 + 10, 50, 100, 200 μg/mL LSPC, MPPC, and CFPC, respectively. Different letters (a, b, c) mean significantly different (p < 0.05) with each other.
