Consumption of wild edible greens (WEG) has risen in Korea recently, and processing of WEG at greenhouses is increasing. In this study, we investigated chamchwi (Aster scaber Thunb), a major WEG, to assess the effect of growth conditions on nutritional quality and blanching process. Field-grown chamchwi had 1.5-2-fold more total phenolic compounds and anti-oxidative capacity than the house-grown one. Among functional compounds, quercetin was significantly higher (about 5-fold) in the field samples (approximately $430{\mu}g/g$ fresh weight) than in the house samples. Soluble sugars in field-grown chamchwi were 2-fold higher than in the house samples. For both the samples, blanching process decreased chamchwi quality significantly, but the degree of loss for each component was different. Consequently, field-grown chamchwi exhibited superior nutritional quality than greenhouse-grown one, and blanching process resulted in a similar decrease of nutritional quality in both the samples.
