Abstract

The floristic region of Adjara represents “Hotpoint” of Caucasian which is distinguished with the uniqueness of its it relict Colchis flora.It represents one of the most powerful refuge in western Eurasia , which is not touched by the chilling because has the special geographical location. There are 176 endemic plants spread in southern Colchis, of which 45 ones can be used for some medical treatments. The bioecology and detailed phytochemical content of some medicinal plant populations have not been studied so far. The research objective is to study the phytochemical content of endemic species of Helleborus caucasicus and Helleborus abchasicus spread in southern Colchis. The research method for the phytochemical content included the separation analysis, which was performed by using UPLC-MS (Waters Acquity QDa detector). Three Steroidal glycosides were isolated from the MeOH extract of the plants of Helleborus caucasicus and Helleborus abchasicus: Hellebrigenin-D-glucose, 20 – Hydroxyecdysone and Hydroxyecdysone – 3 glucoside. Three Steroidal glycosides and Hydroxyecdysone -3 glucoside have been isolated from the MeOH extract of Helleborus caucasicus.

Highlights

  • The floristic region of South Kolkheti (Adjara) isthe part of the Caucasus Ecoregion, which is includedamong the 200 world-renowned ecoregions by the World Wildlife Fund (WWF)

  • It is the first time that we have studied the detailed phytochemical content of Helleborus caucasicus and Helleborus abchasicus rootstocks in southern Colchis

  • Vegetation of Helleborus caucasicus and Helleborus abchasicus begins at the end of November, blooming starts in December, fruiting is in progress in March-April

Summary

Introduction

The floristic region of South Kolkheti (Adjara) isthe part of the Caucasus Ecoregion, which is includedamong the 200 world-renowned ecoregions by the World Wildlife Fund (WWF) These ecoregions are characterized by plant diversity, high levels of endemism, taxonomic uniqueness and rarity of biomes globally [1]. Helleborus caucasicus and Helleborus abchasicus (Ranunculaceae) are evergreen, blooming in autumn-winter-spring seasons, rooted, herbaceous plants, growing on cliffs. Their vegetation begins at the end of November, blooming starts in December, fruiting is in progress in March-April. Colerborine P is used for circulatory disorders of quality II and III, most often in chronic heart failure.
