摘　　要：本文报导了描爪草有效成份RT－A2的EI谱。RT－A2对肿瘤坏死因子（TNF）有较强的诱生作用。RT－A2的分子式被推断为n－C15H31COOH，并讨论了特征碎片离子可能裂解方式。In this paper EI mass spectrography of the active component RT-A2 of the RadixRanunculi ternali were reported. The RT-A, is the inducting agent on the production oftumor necrosis factor (TNF). The molecular formul is n-C15H31 COOH. The fragmentpathway of the characteristic fragment ions were disscused
