Some specific
features of the biochemical composition of the raw material mint (Mentha
spicata var. crispa L.)
Abstract
Abstract. The object of the study was
spearmint – a polymorphic species, which is characterized by strong variability
of both morphological characteristics and biochemical composition. As a result of studies on the form of M. spicata L. and M. spicata L. cv. Moroccan, it
was found that the raw material of this species is characterized by a high
content of phenolic compounds (7.94–9.14%), including flavonoids (2.15–4.35%).
The content of essential oil reached a maximum in the flowering and was 1.54%
in the raw material of the M. spicata L. and 1.48% in the raw material
of the M. spicata L. variety Moroccan. The main components of the
essential oil were carvone and dihydrocarvone, the total content of which in
the essential oil during the flowering phase reached 73.51% or more. The
content of carvone was, depending on the phase of development, increased by the
time of flowering from 57.69 to 60.79% in M. spicata L., cv. Moroccan
and from 65.32 to 79.8% in the sample of M. spicata L., which is comparable to
the content of carvone in caraway seeds. Thus, the raw material M. spicata
L. can be considered as a source of carvone on a par with caraway seeds.
Thus, the studied spearmint samples can be attributed to the carvone chemotype,
and the raw material M. spicata L. can be considered as a source of
carvone on a par with caraway seeds.
