초록
This study evaluated the extraction yield, total phenolic and flavonoid contents, and antioxidant activity of ethanol and water extracts from the branches, bark, and fruits of Sorbus commixta. The fruits exhibited the highest extraction yield, while the bark contained elevated levels of phenolic and flavonoid. Water extraction significantly increased phenol content (1171.86 ± 25.11 mg GAE/g) compared to ethanol extraction (364.45 ± 7.85 mg GAE/g). Antioxidant assays (DPPH, superoxide, TEAC, FRAP, ORAC) demonstrated the superior antioxidant activity of bark extracts, particularly in water extracts (TEAC: 1469.96 ± 11.44 mM TE/g; FRAP: 1690.47 ± 30.59 mM FE/g; ORAC: 943.34 ± 28.53 mM TE/g). These results indicate that S. commixta bark is a potent source of natural antioxidants and a promising candidate for the development of health-functional foods, providing a foundation for further research.
