[Chemical constituents of Scolopendra negrocapitis]

The chemical constituent of Scolopendra negrocapitis Zhang et Wang were systematically analyzed and compared with S. subspinipes mutilans L. Koch. The results showed the lipid content was 18.7%, protein was 63.4% and total amino acid was 11.9%; S. negrocapitis contained the same twelve fat acids (the content of unsaturated fat acid was nearly 64% in its fat acids), twenty one amino acids and twelve trace elements as S. subspinipes mutilans had. The protein of S. negrocapitis showed forteen bands as determined by polyacrylamide gel electrophoresis. S. negrocapitis and S. subspinipes mutilans have the same main chemical composition. The contents of compositions are different. S. negrocapitis is worth as the nature resources of medicinal centepede.
