RESUMO
Constituents of essential oils of sea fennel (Crithmum maritimum L.) collected in different localities of Turkey in 1997 and 1998 have been identified by GC/MS. The effects of collection time and locality on the oil content and composition have been studied. The samples were classified into groups according to the main components: sabinene, gamma-terpiene, methyl thymol and terpinen-4-ol; gamma-terpinene, dill apiol and sabinene; gamma-terpiene, methyl thymol and limonene; p-cymene, methyl thymol and gamma-terpinen. (Z)-beta-ocimene and spathulenol were found with high percentage values in some samples. cis-p-Menth-4-en-1,2-diol was identified in only one oil. Early collected plants yielded oil rich in p-cymene. Effect of freezing plant did not have any important effect in oil composition.
