Abstract

The study was done to assess the cytogenetic effect of oregano by analyzing the effect, oregano extract (0. 25, 50, 75, 100%) on the salivary gland chromosomes of the 0,...,1 multiple- and single-pair parental I). melanogaster The oregano extract did not ha, a significant effect on the number of loose-pairs The number of inversions and were affected at the multiple-pairs parental The pattern for the inversion translocation means decreases at 25%. increases at 50% and lowers below control le\ 's and t00% extract concentration By assuming that the multiple-pairs parental approximates a natural population, it is inferred that oregano causes a decrease on inversion and nan location lends at 25,.. increase at 50% and decrease at 75 and 100%. oregano can then be said to be mutagenic at the 50% extract concentration This can be due to the action of a compound tit the extract Encouragement or discouragement of its use in medicine is not definite
