A comparative study to determine the impact of gas flaring (GF) on some phytoconstituents of five commonly used green leafy vegetables was done. Two locations in south-east states in Nigeria, Ibeno in Akwa Ibom State, a gas flaring (GF) community and Nsukka in Enugu State, a non-gas flaring (NGF) community, were used. Five fresh green leafy vegetable samples were used for this study (Amaranthus hybridus, Gnetum africanum, Talinum triangulare, Telfairia occidentalis, and Vernonia amygdalina) and were obtained from community farmlands during the rainy season between August and November, 2016. After collecting and identifying the green leafy vegetables from five different farmlands in GF and NGF areas and at a distance of about 2km radius from the flare site in GF communities, detailed laboratory analysis was done for alkaloids, flavonoids, saponins and tannins. For A. hybridus, the flavonoid and tannin contents in NGF community were significantly (p
