  1. a Order of elution is given on apolar column (Rtx-1). The compounds with an asterisk (*) were only identified in the essential oils.
  2. b Retention indices of literature on the apolar column (lRIa) reported from [1218].
  3. c Retention indices on the apolar Rtx-1 column (RIa).
  4. d Retention indices on the polar Rtx-Wax column (RIp).
  5. e Percentages are given on the apolar column except for components with identical RIa (percentages are given on the polar column), tr = trace (< 0.05%). Sample locations: Bensekrane (A), Sid Abdeli (B), Terni (C) and Beni Snous (D).
  6. £ Compounds identified from commercial data libraries: National Institute of Standards and Technology, 1999 (12, 33, 39, 43, 44); and König WA, Hochmuth DH, Joulain D, 2001 (26, 34, 35, 36, 40, 41, 42, 46).
