Abstract

|
|
The aim of this study was to investigate the potential of Chaenomeles sinensis as a content of protocatechuic acid and physiological activities. The analyzed the content of protocatechuic acid of Chaenomeles sinensis water extract (CSW) according to different extract temperature and time for extraction. It was analyzed as 0.14±0.00 mg/g in the extract at 100oC for 3 h. Protocatechuic acid content increased as extraction time and temperature increased. The activity of the CSW at 100oC for 3 h was measured. As a result of measuring DPPH, ABTS radical scavenging activity and SOD activity, antioxidant activity was found and a-glucosidase inhibition activities. Cell viability was shown for RAW 264.7 cells, and NO (nitric oxide) production was also inhibited. Finally, content of protocatechuic acid increased with increasing extraction time and extraction temperature, and exhibited antioxidant activity, inhibition of NO production, and anti-diabetic activity. It is believed that the Chaenomeles sinensis is likely to be developed as a functional material.
