a Order of elution is given on apolar column (Rtx-1). Numbers correspond to those in table 1. The compounds that the number is followed by a letter were only identified in HS-fractions.

b Retention indices of literature on the apolar column (lRIa) reported from [12-18].

c Retention indices on the apolar Rtx-1 column (RIa).

d Percentages (means of three analyses) obtained by GC-FID (on RTX-1: apolar column) with peak-area normalization under optimized HS-SPME parameters: temperature: 70°C; equilibrium time: 60 min; extraction time: 30 min. Sample locations: Bensekrane (A), Sid Abdeli (B), Terni (C) and Beni Snous (D).

e Total area is expressed in arbitrary units.

£ The volatile components identified exclusively from the HS-fractions were affected by a letter. Compounds identified from commercial data libraries: National Institute of Standards and Technology, 1999 (1b, 12, 15c, 17a, 19d, 20b); and literature data: König WA, Hochmuth DH, Joulain D, 2001 (3a, 13a, 19b, 19c, 24a, 32b, 35, 36, 36a, 38a, 41, 42).
