Abstract
The essential oils of Ridolfia segetum (L.) Moris and Oenanthe crocata L. (Apiaceae), collected in Sardinia (Italy), have been assayed for two enzyme-associated activities of the HIV-1 reverse transcriptase (RT): RNA-dependent DNA polymerase (RDDP) activity and ribonuclease H (RNase H) activity. In biochemical assays, the essential oils inhibited HIV-1 RT RDDP activity in a dose-dependent manner, while they were inactive towards RNase H activity. Furthermore, the oils were cytotoxic towards K (562) cell replication. GC-MS analysis of the essential oils obtained by steam distillation of the aerial parts showed that the main components of R. segetum were alpha-phellandrene, alpha-terpinolene, beta-phellandrene, and dillapiol and those of O. crocata were sabinene, TRANS-beta-ocimene, CIS-beta-ocimene, and beta-pinene.
