This research was conducted to examine the usability of Cirsium setidens(CS), Aster glehni;(AG), Kalopanax pictus(KP), Anthriscus sylvestris(AS) as functional food in aspects of their functional components and nitrite scavenging ability. Analysis of proximate composition showed that CS contains more crude protein, crude lipid and crude fiber than the other samples. AG showed higher contents in phosphorus, and AS showed higher contents in magnesium, calcium, sodium, potassium, copper, and CS showed higher contents. Total phenol contents was highest in AS as 0.245% and lowest in CS as 0.194%. Regarding nitrite scavenging activity of aqueous fraction, AS appeared strongest as 64.93% at pH 1.2. Regarding nitrite scavenging activity of methanol extracts, KP was appeared strongest as 66.73% at pH 1.2.
