“…In addition to the three species mentioned above, the root of E. angustifolium and the herbs of E. parviflorum, E. plantagineum, and E. russicum have also been reportedly used in Turkish traditional medicine [27,28,[37][38][39]. For example, the aerial parts of E. plantagineum are locally known as 'Engerek ut', and its decoction is prepared as a tea with diaphoretic and diuretic effects [27] (Table 1).…”

“…Phenolic acids are also commonly distributed in Echium species. One of the best-characterised compounds isolated from the Echium genus is rosmarinic acid, which is found in several Echium species, such as E. amoenum, E. russicum, and E. vulgare [24,38,90,94]. Moreover, when extracted with hot water, E. amoenum petals were shown to have the highest content of rosmarinic acid within these species [52].…”

“…Moreover, when extracted with hot water, E. amoenum petals were shown to have the highest content of rosmarinic acid within these species [52]. Other phenolic acids have been well characterised in E. russicum, including salvianolic acid A, rabdosiin, lithospermic acid, and eritrichin (globoidnan A) [38]. All of these phenolic phytochemicals could explain the ethnomedicinal success of these species and represent a potential source of potent antioxidants, antivirals, anti-inflammatories, and potentially, antibacterial agents, which have limited published biologically related mechanistic data to date.…”

Antioxidant Properties and Reported Ethnomedicinal Use of the Genus Echium (Boraginaceae)

et al. 2020

View full text Add to dashboard Cite

The genus Echium L. from the Boraginaceae family consists of 67 recognised species. The genus is widely distributed in the Mediterranean, having been documented in the traditional medicine of the area since 300 B.C. Current pharmacological studies have validated early ethnomedicinal properties showing that Echium spp. possesses antioxidant, analgesic, anxiolytic, anti-inflammatory, antibacterial, and antiviral effects. Nevertheless, only limited papers report specifically on the phytochemistry of this genus. Furthermore, the potential of utilising extracts from Echium species as natural antioxidant preparations has been significantly neglected. For the first time, this review comprehensively describes and discusses the presence of recorded Echium species with ethnomedicinal uses, their antioxidative properties in vitro and in vivo when available, and major phytochemical components recognised as potent antioxidants, as well as the possibilities and opportunities for future research.

“…As other plants from Boraginaceae family, Russian bugloss contains valuable compounds which make it a natural source of antioxidants [ 11 ]. It contains a considerable amount of rosmarinic acid and shikonine—well-known compounds with medicinal properties [ 12 , 13 ]. The seeds with high content of omega-3 and omega-6 fatty acids make it a valuable plant for cultivation and production of useful fatty acids [ 14 ].…”

Pontechium maculatum, a species of ornamental, apicultural, health and medicinal value, is threatened in some Central European countries including Poland. Its propagation using seeds or in vitro techniques is needed for multiple applications including conservation. Generative propagation efficacy of P. maculatum plants representing different genetic resources (received from botanical gardens in Germany and in Poland) propagated from seeds or in tissue culture was assessed. Moreover, an efficient technique of propagation of P. maculatum using in vitro shoot culture from seedlings was elaborated for the first time. The highest propagation efficacy was noted for German plants of seed origin. The ability of seeds to germinate was similar for all plants; however, seeds were in a state of dormancy, which was broken by GA3. After two years of storage, the seeds still retained the ability to germinate though seeds from propagated in vitro plants germinated more poorly than those from seed-originated plants. The ploidy assessment showed that some in vitro-origin plants had altered DNA content. The results indicate that efficacy of generative propagation of P. maculatum is resource dependent. Furthermore, results suggest that cultivation in vitro influenced some generative features of examined species, which makes this way of P. maculatum propagation a valuable source of genetic variation and a potential breeding tool.
