Abstract
Myrica gale L. (Myricaceae), a native plant from Canada used in traditional medicine, was extracted by hydrodistillation and the oil was collected after 30 and 60 min. The chemical composition of these two extracts was determined using GC-MS analysis. We identified 53 components and myrcene (23.18-12.14%), limonene (11.20-6.75%), alpha-phellandrene (9.90-6.49%) and beta-caryophyllene (9.31-10.97%) were the major components in the 30- and 60-min fractions, respectively, whereas higher caryophyllene oxide content was detected in the 60-min fraction (9.94%) than in the 30-min fraction (3.47%). The anticancer activities of these extracts were assessed against human lung carcinoma cell line A-549 and human colon adenocarcinoma cell line, DLD-1. The 60-min fraction showed higher anticancer activity against both tumor cell lines with an IC50 value of 88 +/- 1 microg/ml. The 30-min fraction had an IC50 value of 184 +/- 4 microg/ml for A-549 and 160 +/- 3 microg/ml for DLD-1. The higher cell growth inhibition induced by the 60-min fraction, as compared to the 30-min fraction, could be due to sesquiterpene enrichment.Entities:
