Abstract
A comparative chemical analysis of Agastache mexicana subsp.
mexicana and A. mexicana subsp. xolocotziana reveals that
their methanol extracts constituents were very similar, with acacetin and
(2-acetyl)-7-O-glucosyl acacetin being the most abundant compounds obtained.
These results are consistent with the information reported for other species of
Agastache. However, GS-MS analyses showed that methyl chavicol, limonene
and linalool were the main constituents of the essential oils of A.
mexicana subsp. mexicana, while pulegone, menthone and isopulegone
were the major constituents found in A. mexicana subsp.
xolocotziana. Furthermore, a different composition was found in their
respective hexane extracts. These chemical composition dissimilarities between
the two taxa support their recognition as distinct subspecies.
