Purine contents of soybean-derived foods and selected Japanese vegetables and mushrooms.

ABSTRACT

Purine contents of soybean-derived food and various other Japanese foods were quantitatively determined by high-performance liquid chromatography (HPLC). Purine contents were as follows soybean-derived foods, 21.9-172.5 mg/100 g or 100 mL; Japanese vegetables, 2.3-171.8 mg/100 g; Japanese mushrooms, 9.5-142.3 mg/100 g. Since purine levels in these foods did not exceed 200 mg/100 g, we recommend that eating of them should be adopted and good dietary habits followed.
