The purpose of this study was to evaluate antioxidant and cancer cell growth inhibition activity by extract nature‐friendly compost, organically and conventionally cultivated lettuce. We determined the anthocyanin, phenol and flavonoid contents and examined antioxidant assay, such as DPPH, ABTS and reducing power. Also, we performed HepG2 cancer cell growth inhibition assay of lettuce extract. The lettuces of nature‐friendly compost and organic exhibited the highest values of antioxidant activity, total polyphenol and flavonoid contents were the highest in nature‐friendly compost lettuce and organic lettuce. In cancer cell growth inhibition activity in a dose‐dependent manner, nature‐friendly compost lettuce extract had growth inhibition activities greater than 90% on HepG2 cell. The results of this study suggest that the antioxidant and anticancer activities in lettuce cultivars grown under nature‐friendly compost and organic conditions are a promising source of functional food ingredients.
