This study aimed to compare the physicochemical properties of tea leaves, green tea and soil from the wild forests in the Juam and Namwon areas. The moisture and crude protein contents of the green tea in the Namwon area were higher than those of the tea from theJuam area (p < 0.05). A total 4 free sugars and 7 organic acids were found in the tea leaves and green teas. The fructose levels of tea leaves and green tea in the Juam area were higher than those of the leaves and tea in the Namwon area, but the glucose level in the green tea from the Namwon area was higher than that in the tea from Juam (p < 0.05). The oxalic acid, malonic acid, acetic acid and citric acid contents of the tea leaves and green tea from Namwon were higher than that in the leaves and tea from the Juam area (p < 0.05). In all of the samples analyzed, epigallocatechin gallate (EGCG), gallic acid, and epigallocatechin (ECG) were found to be the major catechins in the tea leaves, while EGCG, ECG, and epicatechin (EC) were found to be the major catechins in the green tea. The caffeine levels of the tea leaves and green tea from the Namwon area were higher than those of the leaves and tea from the Juam area. Amongst the free amino acids analyzed, threonine+theanine, alanine, tyrosine, serine, and arginine were found to be the major free amino acids in the tea leaves, while threonine+theanine, glutamic acid, serine, and arginine were found to be the major ones in the green tea. The total amino acid content of the tea leaves and green tea from Namwon were higher than those of the leaves and tea from the Juam area. In the properties of the soil analyzed, the moisture content and Hunter’s color value were higher in the Namwon area, but the crude ash content was higher in the Juam area. The pH, E.C, O.M, Av.P2O5, K, Ca, Mg, Na and T-N values of soils in the Juam area were higher than those of the soils in the Namwon area.
