“…Gentianae radix is made up of desiccated rhizomes and roots of Gentiana lutea L. (Family: Gentianaceae), which appear as sole or branched sub cylindrical sections of various lengths and thicknesses, often 10-40 mm. The gastro-protective activity of Gentian root methanolic extract was investigated, and the results revealed that the healing effect of Gentian roots on gastric wound were linked to increased mucosal protective features via the prostaglandin pathway, with secoiridoid glycosides being accountable for this action 71,72 .…”

Peptic ulcer is a disorder that commonly has an effect on the digestive system. It is a chronic illness which has impact on approximately, 10% of the mankind. The majority of current therapy regimens are based on western medicine. Proton pump inhibitors (PPIs) and histamine-2 (H2) receptor antagonists, which are commonly used to treat peptic ulcers, have been linked to side effects, relapses, and drug interactions. However, several investigations have shown that herbal medications can efficiently heal stomach ulcers in humans and animals using different processes. As a result, this review will focus on common plants with medicinal value which can be utilized to cure or prevent peptic ulcers.

“…Volis & Blecher (2010) запропонували нову стратегію реінтродукції, під назвою «квазі in situ», яка передбачає п'ять важливих етапів від первинного аналізу розподілу рідкісних видів у природі, відбору їх матеріалу, розмноження рослин в умовах, які максимально відповідають їх екологічним потребам, дослідження життєвого циклу видів та визначення комплексу абіотичних та біотичних факторів, що впливають на їх популяційну структуру, до за-ключного етапу моніторингу успішності реінтродукції цих так-сонів у природні умови. При цьому поряд із традиційними мето-дами розмноження та отримання посадкового матеріалу все час-тіше пропонується використовувати біотехнологічні (Sarasan et al, 2006;Bisht et al, 2017;Keziah & Devi, 2017), зокрема, метод мікроклонального розмноження іn vitro, який дозволяє швидко отримати рослинний матеріал, необхідний для відтворення та повернення у природу представників багатьох видів рослин (Kiran et al, 2014), у тому числі видів роду Gentiana L. (Drobyk et al, 2015), зокрема, його рідкісного високогірного таксона -Gentiana lutea L. (Drobyk et al, 2015;Hrytsak et al, 2017).…”

New technologies of reintroduction of plant species presuppose implementing both traditional and biotechnological methods for obtaining certain planting materials. However, plants cultivated in vitro exist in specific conditions that lead to changes in their structural and functional state. This explains why it is hard for them to adapt to ex vitro and in situ conditions. Therefore, there is a need for the development of a multistage method of cultivating in vitro plants that would make the influence on their adaptive mechanism in ex vitro and in situ conditions possible. One of its stages is the optimization of the light regime of cultivation which can both initiate the change of the state of the photosynthetic apparatus of plants and increase their bioproductivity stimulating the work of their protective system. This work studies changes in the morphogenesis, growth data and pigment composition of the rare species of Gentiana lutea L. of three populations in the Ukrainian Carpathian (mountains Pozhyzhevska and Sheshul-Pavlyk, plateau Lemska) in vitro focusing particularly on the cultivation light regime. The research has proved the inefficiency of using fluorescent lamps of daylight lamps (LD) type as source of illumination because the low intensity of luminous flux in the area of photosynthetically active radiation (PAR), as well as high proportion of wavelength of blue (400–500 nm) and green (500–600 nm) range in the spectrum cause specific reactions of photomorphogenesis, which, despite the high content of pigments in plastids, lead to poor development of root systems, stretching the stems, formation of small leaves with thin leaflet plate, generally low productivity and low adaptive potential of G. lutea plants to ex vitro and in situ conditions. Complement of cold white light lamps to the fluorescent lamps LD type in the ratio of 1 : 1 enables one to increase the intensity of illumination in the field of PAR and raise the fraction of wavelength of red range (600–700 nm). Such light conditions both improve the bio-productivity of G. lutea plants of all three populations cultured in vitro in comparison to the LD type regimen, reducing the content of chlorophyll b and carotenoids in light-harvesting complexes of photosystems and facilitate an increase in the microclonal multiplication factor without using higher concentrations of exogenous growth regulators,which significantly reduces the cost of the process of obtaining planting materials. It was proved that a combination of LD type lamps, cold white light lamps and phytolamps in the ratio 1 : 1 : 0.6 should be used on the final stages of preparation of the planting material of G. lutea before transferring it to ex vitro and in situ conditions. This relates to the fact that the increase of the wavelength of the red range results in the widening of the active surface of the leaves, rise in the content of photosynthetic pigments, and the noticeable growth of the aboveground and underground parts of the plants. The article assumes that the use of such illumination mode will ensure a faster transition of cultured in vitro G. lutea plants from heterotrophic to autotrophic nutrition, improving their adaptive potential and enabling easier adaptation to non-sterile ex vitro and in situ conditions.

The increasing availability of plastid genomes represents a new opportunity to explore molecular evolution in plants (Tonti-Filippini et al., 2017;Twyford & Ness, 2017). For example, plastid phylogenomics has resolved some persistent taxonomic uncertainties in challenging plant groups (e.g., in Rosaceae; Zhang et al., 2017), and more generally led to a better understanding of major events in plant
