This study evaluated the in vitro radical scavenging activities of edible tree sprouts, particularly those of the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), hydroxyl radical, and singlet oxide radical, to assess their antioxidant activities. Additionally, stigmasterol (ST) and β-sitosterol (BS) were analyzed using HPLC/UV. The edible sprouts of Eleutherococcus senticosus (ESC) and Morus alba (MAB) exhibited the highest DPPH scavenging activity among other edible sprouts. A reverse-phase column was used in an isocratic elution system, after which UV detection was performed at 210 nm. ST and BS analyses indicated that ESC sprouts contained the highest amounts of ST (9.99 mg·g− 1 extract), whereas MAB sprouts contained the highest concentrations of BS (14.69 mg·g− 1 extract). In conclusion, the highest antioxidant activity was observed in the edible sprouts with the highest phytosterol content. Therefore, our findings provide a theoretical basis for the development of plant-based functional foods or supplements with antioxidant properties.

The phenolic compounds extracted from Aster scaber were examined for their biological activities owing to their potential use in health and beauty food products. The phenolic content in water and 60% ethanol extracts were 11.1±0.11 and 4.18±0.05 mg/g, respectively. The DPPH radical scavenging activities of the water and ethanol extracts were 87% and 91% at 50 μg phenolics/mL, respectively. At the same phenolics concentration, the respective extracts showed 84% and 95% for ABTS radical decolorization activities and 95% and 97% for TBARs. The antioxidant protection factors for the water and ethanol extracts at 200 μg phenolics/mL were 1.87 and 2.22 PF, respectively. Enzyme inhibitory activities of the water and ethanol extracts (50 μg phenolics/mL) were 50.8% and 69.4% on angiotensin converting enzyme, 91% and 80% on xanthine oxidase, and 24% and 89% on α-amylase, respectively. The tyrosinase inhibitory activities indicating skin-whitening were 47% and 25% for the water and ethanol extracts, respectively. Anti-wrinkle effect of the water extract was relatively higher than that of the ethanol extract. These results suggest that the water and ethanol extracts of Aster scaber can be used as an ingredient in health and beauty food products.
