Two varieties of Mentha, viz. Krasnodarskaya-2 and a Vietnamese variety HB-74, were examined for abscisic acid (ABK) and phenol compounds (chlorogenic, caffeic, cinnamomic, ferulic and salicylic acid) accumulation in the leaves of the 3rd, 7th and 12th layers in the course of plant ontogeny. Krasnodarskaya-2 was found to maintain the higher leaf ABK level during the whole period of vegetation. No specific trends concerning the identified phenol compounds accumulation dynamics were traced. The chlorogenic acid was detected in the leaves beginning only with the 7th layer, the leaf salicylic level revealed a tendency to considerably increase beginning with the 12th layer, it also showed a clear correlation with the essential oil output during the whole period of the leaf development
