김경진 ․ 장재원 ‧ 이인순 ‧ 박흠대 대구대학교 산업기술연구소 2018 産業技術硏究 Vol.29 No.2
We experimented to investigate the anti-aging effect on the extracts of Asparagus officinalis L. (asparaguse), Eleutherine Americana Merr. (shallot) and Brassica oleracea var. gemmifera (Brussels sprouts). It was respectively extracted for 7 days at 4 ℃ with 70% EtOH and water as solvent and those extracts were determined the concentration of total polyphenolic compound, flavonoid, free radical scavenging as DPPH and catalase activity. In a result, the water and 70% EtOH extract of asparagus were showed over 50% activity of DPPH radical scavenging. The extracts of shallot were had high concentration of polyphenol and flavonoid than the extracts of other sample, but DPPH radical scavenging was found more low activity than the other sample. The extracts of Brussels sprouts were showed lowest concentration of polyphenol and flavonoid among samples, but DPPH radical scavenging was measured highest activity over 60%. And the extract of asparagus and Brussels sprouts were reversely increased the activity of DPPH radical scavenging in a case of the treatment of low concentration. Catalase was confirmed high activity the extract of asparagus tissue and the extract of Brussels sprouts tissue in order. Therefore, Asparagus officinalis L. and Brassica oleracea var. gemmifera have the effect of anti-aging and it is good garnish vegetable eating with meat.
