Morphological analysis of <i>Polemonium Coeruleum</i> L. herb using stereo- and luminescent microscopy

Abstract

Aim to establish the morphological features of the ground part of Polemonium coeruleum L. Material and methods. The material of the study was the samples of Greek-valerian polemonium grass (Polemonium coeruleum L.), cultivated and harvested in the Voronezh region, the city of Bobrov, during the flowering period in the second year of life in 2021. The State Pharmacopoeia XIV standard ed. OFS.1.5.3.0003.15 "Technique for microscopic and microchemical examination of medicinal plant materials and medicinal plant preparations" was used for macroscopic analysis. Results. When studying the Greek-valerian polemonium herb, its external features were described, which can be used for "Authenticity" section when developing regulatory documentation for this type of plant material. The difference in the pubescence of Greek-valerian polemonium leaves depending on their topography was established. The presence of simple multicellular trichomes on all parts of the plant, as well as glandular trichomes on some elements of the flower, was revealed. For the first time, the nature of the autoluminescence of tissues of the Greek-valerian polemonium grass was described.
