Chemical constituents of fruit peels of Fortunella japonica Swingle were investigated, and ten compounds were purified and isolated through various chromatographic procedures. Through NMR analysis, isolated compounds were identified as ${\alpha}$-tocopherol (1), lupenone (2), ${\beta}$-amyrin (3), ${\alpha}$-amyrin (4), ${\beta}$-sitosterol (5), ${\beta}$-sitosteryl 3-O-glucopyranoside (6), kaempferide 3-O-rhanmopyranoside (7), 3',5'-di-C-${\beta}$-glucopyranosylphloretin (8), acacetin 7-O-neohesperidoside (9), and acacetin 8-C-neohesperidoside (10). Compounds 1-7 were identified for the first time by our group from fruit peels of F. japonica.
