Abstract: There are 176 endemic plants spread in southern Colchis, of which 45 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 objectiveis to study the phytochemical content of endemic species of Helleborus caucasicus, Helleborus
abchasicus and Ficaria popovii spread in southern Colchis.
The research method for the phytochemical content included separation analysis, whichwas performed byusing UPLC-MS
(Waters Acquity QDa detector).
Three Steroidal glycosideswere isolated from the MeOH extract of the plants of Helleborus caucasicus and Helleborus
abchasicus: Hellebrigenin-D-glucose, 20 – Hydroxyecdysone and Hydroxyecdysone – 3 glucoside. Two saponins
(Hederagenin 3-O -α-L-arabino pyranoside, Hederagenin28-O-[α-L-rhamno-pyranosyl(1→4)-β-D-glucopyranosyl-(1→6)]βD-lucopyranoside) and four flavonoids (kaempferol 3-O-β-ᴅ- (6ʺ-α-ʟ-rhamnopyranosyl)-glucopyranoside (nicotiflorin),
apigenin 8-C-β-ᴅ-glucopyranoside (vitexin), luteolin 8-C-β-ᴅ-glucopyranoside (orientin), quercetin 3-O-rutinoside) were
isolated from the tubers and flowers of Ficaria Popovii.
Three Steroidal glycosides and Hydroxyecdysone -3 glucoside were isolated from the MeOH extract of Helleborus
caucasicus.In addition, two saponins and four flavonoids were isolated from the tubers and leaves of FicariaPopovii.

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 (IUCN. 2006).
Southern Kolkheti (Adjara), in the Caucasus ecoregion, is characterized by the special diversity and
originality of the flora, which is present due to the flora complexes rich in plant clusters and relict, and
endemic species formed in the third period(Manvelidze et al., 2010).
1837 species of plants are common in southern Colchis, including 176 endemic ones (Varshanidze et
al., 2018).Among the endemics, the following genera are distinguished by their decorative and
medicinal properties: Helleborus and Ficaria, bothspecies of genusflower in winter-early spring.

The genus Helleborus is represented by 2 species: Helleborus caucasicus and Helleborus abchasicus.
Furthermore,the genus Ficaria is represented by 1 species -Ficaria popovii.(Dmitrieva, 1990).
Helleborus caucasicusandHelleborus abchasicus(Ranunculaceae) are evergreen, blooming in autumnwinter-spring seasons, rooted, herbaceous plants, growing on cliffs. Their vegetation begins at the end
of November, blooming starts in December, and fruiting is in progress in March-April. Ficaria
popovii (Ranunculaceae) is endemic of the narrow-local ephemeroid nature of Adjara.Its vegetation
begins in November, blooms in January-February, fruiting is in progress in March-April, and dries in
early May.Among these species, Helleborus caucasicus and Helleborus Abchasicus are widely
distributed. Helleboruscaucasicus is an important source of chemical compounds with a great medical
potential for the treatment of some serious diseases such as cancer, ulcers, diabetes, as well as some
medical problems such as toothache, eczema, low immunity and arthritis. Ficaria popovii tubers and
leaf extracts are used as a diuretic, blood purifier and wound healer, as well as in salads made from
leaves that cleanse the blood of pathogenic microbes (Jakeli et al. 2018).
It is the first time that wehave studied the detailed phytochemical content of Ficaria popovii tubers
and leaves,and Helleborus caucasicus and Helleborus abchasicus rootstocks in southern Colchis.
Methods and materials
Plant material: the leaves, tubers and rhizomes of three species-Helleborus caucasicus H.
Abchasicus,Ficaria popoviithat were collected in Adjara(Tab. 1).

Ultra Performance Liquid Chromatography (UPLC)- Preparation of a sample for chromatographic
examination of saponins: Various parts of the plant Ficaria popovii were taken for analysis - Flower,
leaves and tubers, and the rhizomes and leaves of Helleborus caucasicus and Helleborus abchasicusas
well. Raw material of the sample was taken for analysis, Extraction of the crushed sample (2.5 g) was
performed with methanol (100% 50-50 ml) three times in an ultrasound bath.The next step intended to
filter the extracts by using a vacuum pump.We concentrated methanolic extracts at a temperature of
4000C under vacuum conditions until there was an aqueous residue.(In the case of concentrated leaf
extract, the sample was further treated with chloroform to remove chlorophyll green pigments).In
order to elute and concentrate saponins, we divided the concentrated water fraction by C18.In the
initial stage, the sorbent was conditioned, in particular, the sorbent was activatedwith methanol and
balancedby using water.In the first stage after sampling, we removed unwanted components with
water.In the final stage, the research components wereeluted with methanol (100%).The resulting
eluent waslater concentrated to a dry mass.For chromatographic analysis, dry mass extraction was
performed by using the mobile phase (acetonitrile: a mixture of methanol).The sample for
chromatography was filtered into a 0.45 μm filter.
The flavonoids were tentatively identified according to their retention time (Rt), the wavelength of
maximum absorbance (λmax), pseudomolecular ion ([M−H]-) and compounds mass database
METLIN (https://metlin.scripps.edu).
Concentration of analytical samples:Ficaria popovii - flower - g/200 μl (2.5 g/500 μl), leaves - g/25 μl
(20 g/500 μl) and tubers - g/50 μl (10 g/500 μl).Helleborus caucasicus rhizomes - g/80 μl (15 g / 1200
μl) and leaves - g/4 ml (15 g/60 ml). and Helleborus abchasicus rootstock - g/200 μl (10 g/2000 μl)
and leaves - g/4 ml (10 g/40 ml).
Results and discussion
The detected flavonoids of Ficaria popovii are presented in Table 2. Four flavonoids were found, the
UPLC - flavonoids profile of the ethanolic extract of the sample Tuber (The substance 1, 2, 3 and 4)
and flower (The substance 1 and 2) of Ficaria popovii). Flavonoids Composition of Ficaria popovii

Ecdysterone and Furostan, and 4 in tubers - Ecdysterone, Bufadienolide, Furostan and HellebrigeninD-glucose. Based on the obtained results, it can be concluded that the steroid composition of leaves
and tubers of Helleborus caucasicus and Helleborus abchasicus is similar.
Conclusion
Vegetation of Helleborus caucasicus and Helleborus abchasicus begins at the end of November,
blooming starts In December, and fruiting is in progress in March-April. Ficaria popovii
(Ranunculaceae) blooms in January-February, fruiting is in progress in March-April, and dries in early
May.
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. Two saponins (Hederagenin 3-O -α-L-arabino pyranoside,
Hederagenin28-O-[α-L-rhamno-pyranosyl(1→4)-β-D-glucopyranosyl-(1→6)]β-D-lucopyranoside)
and four flavonoids (kaempferol 3-O-β-ᴅ- (6ʺ-α-ʟ-rhamnopyranosyl)-glucopyranoside (nicotiflorin),
apigenin 8-C-β-ᴅ-glucopyranoside (vitexin), luteolin 8-C-β-ᴅ-glucopyranoside (orientin), quercetin 3O-rutinoside) have been isolated from the tubers and flowers of Ficaria Popovii.
On the basis of the conducted analysis,it is possible to make a conclusion that 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
glucosides. While, two saponins and four flavonoids were isolated from the tubers and flowers of
Ficaria Popovii.
Steroidal glycosides, saponinsand flavonoids, that contribute to the biological activity of the plants,
were identified in the leaves and tubers of Ficaria Popovii, Helleborus caucasicus and Helleborus
abchasicus.
