STUDY ON EXTRACTION OF FLAVONOIDS FROM FRUIT OF ROSA DAVURICA P ALL BY DIFFERENT METHODS AND ITS ANTIOXIDANT ACTIVITY
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Taking the extraction yield of total flavonoids from fruit of Rosa davurica Pall. (FRDP) as index, the optimum extraction technology and in vitro antioxidant properties of flavonoid obtained from various modern extraction techniques were explored. The scavenging ability for DPPH· and ABTS+· of FRDP extracts were investigated. The extraction rate of flavonoids using microwave synergistic enzyme method was relatively higher than that of other extraction technique. The scavenging ability for DPPH· and ABTS were employed to evaluate the antioxidant activity of flavonoids, rutin and Vc. Results showed flavonoids had a strong scavenging ability for DPPH· and ABTS+·, and its scavenging activity gradually increased with the increasing mass concentration of flavonoids from FRDP
