摘要
Sardinian wild Euphorbia pithyusa, E. semiperfoliata, E. dendroides and E. characias seed oils were analyzed for their fatty acids, unsaponifiable and tocopherol content. Total tocopherol content showed a wide variability, ranging from 939 mg/kg in E. semiperfoliata seeds to its absence in E. characias. The results on tocopherol content were statistically correlated with both 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging test and the P-carotene bleaching antioxidant test. All seeds were rich in linolenic acid, while no uncommon fatty acids were detected. (C) 2003 Elsevier B.V. All rights reserved.
