AB  - Sweet potato leaves are consumed globally for their nutritional and functional properties, with their taste characteristics significantly influencing their market value and consumer acceptance. However, the metabolic factors determining the taste of sweet potato leaves remain unclear. This study evaluated the taste and metabolic profile of sweet potato leaves cultivated in soil and hydroponic systems, revealing that hydroponic culture improved the taste of the leafy sweet potatoes. Using gas chromatography system (GC)-ToF-MS, 200 metabolites were identified, encompassing most plant metabolic pathways. A comparison of good-tasting <i>vs.</i> poor-tasting sweet potato leaves identified 71 metabolites associated with taste quality formation. Poor-tasting leaves exhibited lower levels of amino acid metabolites and higher levels of carbohydrate and secondary metabolites. This research provides novel insights into enhancing the taste of leafy sweet potatoes.
