From 19 species of Galium, members of 6 European sections of the genus, 24 compounds were isolated, namely 16 iridoid glucosides, 2 secoiridoid glucosides and 6 triterpene saponins (the later found only in G. rivale (Sibth. & Sm. Griseb.) The iridoid content was analyzed by thin layer chromatography - densitometry. An effort was made to clarify int...

TheRorippa pyrenaica group is represented in the area of Balkan Peninsula byR. pyrenaica (diploid),R. lippizensis (diploid), andR. thracica (diploid and tetraploid). They differ morphologically from all other EuropeanRorippa species by their pitted reticulate seed surface.Rorippa pyrenaica is characterized by ovoid elipsoidal siliculae, up to three...

The coumarin and iridoid composition of Crucianella graeca, Cruciata glabra, Cruciata laevipes and Cruciata pedemontana has been studied. Daphnin and daphnetin glucoside dominated in C. glabra along with low concentrations of daphnetin, deacetylasperulosidic acid and scandoside. In C. laevipes and C. pedemontana were found the same coumarin glucosi...

The Balkan endemics G. mirum, Galium macedonicum, G. rhodopeum and G. aegeum, from the G. incurvum group, were screened for iridoid glucosides. Eleven known iridoid glucosides were isolated, identified and analysed for the first time in the investigated plants. The main components appeared to be asperuloside and/or the non-acetylated iridoid acids...

Iberis saxatilis subsp. saxatilis occurs in the Bulgarian fl ora in few localities in the eastern and southwestern mountainous parts of the country. A comparative embryological study of three populations with diff erent ploidy levels has been carried out. Th e mode of reproduction, peculiarities of male and female gametophytes, and embryo- and endo...

... Since F. meleagroides is an endangered species in a large part of its natural range, including eastern Europe [IVANOVA, 2015;KOROTCHENKO & ORLOV, 2009;PETROVA & VLADIMIROV, 2009], we expressed the view that urgent actions to protect its populations from Romania should be introduced [OPREA & al. 2015]. ...
... As the genus Achillea is a model for remarkable eco-geographical radiation spreading across southeastern Europe and southwestern Asia with extensions through Eurasia to North America, and demonstrated numerous cases of polyploidy (2x-4x-6x-8x), transition zones between species, hybridization and excessive polymorphism , more specimens (52) from different localities were chosen to determine the palynological features of these species (Ehrendorfer 1959; Vetter et al. 1996a Vetter et al. , 1996b Saukel et al. 2004; Guo, Ehrendorfer, and Samuel 2004; Guo et al. 2005; Ehrendorfer and Guo 2006; Sahin et al. 2006; Kıran et al. 2008, 2012). The examined species are the yellow and two to eight liguled members of the traditional section of Achillea: section Santolinoidea DC., which were incorporated into sect. ...
... We propose to consider the present zonal and extrazonal vegetation types of the above-mentioned locations as approximate analogues of the HTM vegetation of the middle and northern part of the Pannon region. For instance, Plovdiv falls into the northern edge of the distribution of oriental plantain (Platanus orientalis; Biserkov et al., 2015), and the species is not native further north presently. Nevertheless, this species could have occurred until the HTM period in the Pannon region and many other species (Celtis australis, Quercus pedunculiflora, etc.) also could have been present which are now found only south of the Carpathians. ...
... and Kit ex Willd., and A. pannonica Scheele. Data point to A. collina being the most largely distributed species in the country, and question the notion of the predominance of A. setaceae ( Saukel et al., 2003;Vitkova et al., 2005). Presently the increasing demand of yarrow drug is predominantly met by collecting wild-growing plants from their natural habitats. ...

(c) Achillea thracica is threatened in only two countries (Romania: Critically Endangered and Bulgaria: Vulnerable) but is endemic to these two countries and therefore at risk of global extinction.

... Phytochemical studies have shown that both Galium and Cruciata genera synthesize many different classes of specialized metabolites, such as iridoid glycosides, antraquinones, phenolics, flavonoids, and coumarins [8][9][10][11][12][13][14][15][16][17], possibly accounting for the biological properties highlighted for some of the species. They also produce terpenoids and aromatic essential oils [18][19][20][21]. ...

... Their structural determination was performed by 1D and 2D NMR spectroscopic techniques, mass spectrometry analyses, and comparison of these data with those reported in the literature. Isolated compounds included six iridoid glycosides identified as asperuloside (1) (Otsuka et al., 1991), geniposidic acid (2) , iridoid V1 (3) (Mitova et al., 1999), deacetylasperuloside (4) (Otsuka et al., 1991), monotropein (6) (Tzakou et al., 2007), and daphylloside (7) ; one non-glycoside iridoid macedonine (5) (Mitova et al., 1996); two p-coumaroyl iridoid derivatives, 10-O-p-coumaroyl-10-deacetyldaphylloside (8) (Ahn and Kim, 2012) and 10-O-p-coumaroyl-10deacetylasperuloside (9) (Bai and Hu, 2006); two phenolic acids characterized as p-hydroxyhydrocinnamic acid (10) and chlorogenic acid (11) (Owen et al., 2003); and two flavonoid glycosides rutin (12) and apigenin-7-O-glucoside (13) (Agrawal, 1989). Isolated iridoids, except 9 that was obtained in too small quantity, were subjected to CAM assay in order to evaluate their anti-angiogenic effects. ...
... The natural A. hippocastanum populations have been little studied and are considered endangered and in decline according to the IUCN Red List of Threatened Species (The International Union for Conservation of Nature) (Khela 2013). Other than the sites in Greece, A. hippocastanum can be found in Macedonia, Bulgaria (Petrova and Vladimirov 2009), and Albania (Peçi et al. 2012). The horse-chestnut populations in Bulgaria are small, and the area in which they occur is limited (Peev et al. 2011). ...
