Contents of nutritional components and mineral elements in tender stem and leaf (edible part) of Cryptotaeniajaponica 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 VC 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.
