Contents of nutritional components and mineral elements in tender stem and leaf ( edible part) of Cryptotaenia japonica Hassk., C. japonica var. atropurpurea Makino and C. canadensis ( Linn.) DC. of Cryptotaenia DC. in Apiaceae were analyzed, and their nutritive value was evaluated. The results show that water content in tender stem and leaf of them is 79. 75% -81. 09% , there is no significant difference; their contents of total sugar, crude fiber, crude protein, crude fat and V C are 1. 44% -2. 02% , 21-25 g· kg^-1 , 38. 4-49. 2 g· kg^-1 , 4. 7-6. 1 g· kg^-1 and 0. 434 6-0. 577 9 mg· g^-1 , respectively , and contents of K , Ca , Mg , Fe , Zn and P are 3. 503 3-5. 914 1, 1. 518 8-2. 307 0, 0. 052 7-0. 087 0, 0. 117 0-0. 371 1, 0. 007 5-0. 010 0 and 0. 004 3-0. 011 3 mg· g^-1 , respectively, there are significant differences in all items. Average nutritive value of tender stem and leaf of three plants is 12. 19-25. 17, which is obviously higher than that of the common vegetables, meaning that Cryptotaenia plants can be developed and utilized as a kind of the new health vegetables.
