“…Veronica L. (Plantaginaceae) is a genus of about 450 species ( Albach and Meudt, 2010 ) occurring over most of the Northern Hemisphere and in many parts of the Southern Hemisphere ( Mabberley, 2008 ). Modern systematic studies of the genus have focused on molecular phylogenies of several nuclear and plastid markers: the nuclear ribosomal internal transcribed spacer, nrITS ( Wagstaff and Garnock-Jones, 1998 ; Albach and Chase, 2001 ; Albach et al, 2004 ; Buhk et al, 2015 ), the plastid regions trn L-F ( Albach et al, 2004 , 2006 ; Buhk et al, 2015 ), ndh F- rpl 32 ( Sonibare et al, 2014 ; Albach and Al-Gharaibeh, 2015 ; Buhk et al, 2015 ), trn H- psb A ( Sonibare et al, 2014 ; Albach and Al-Gharaibeh, 2015 ), rps 16 intron ( Albach and Chase, 2004 ), rps 16– trn K ( Sonibare et al, 2014 ; Albach and Al-Gharaibeh, 2015 ).…”

Veronica officinalis Product Authentication Using DNA Metabarcoding and HPLC-MS Reveals Widespread Adulteration with Veronica chamaedrys

Studying herbal products derived from local and traditional knowledge and their value chains is one of the main challenges in ethnopharmacology. The majority of these products have a long history of use, but non-harmonized trade and differences in regulatory policies between countries impact their value chains and lead to concerns over product efficacy, safety and quality. Veronica officinalis L. (common speedwell), a member of Plantaginaceae family, has a long history of use in European traditional medicine, mainly in central eastern Europe and the Balkans. However, no specified control tests are available either to establish the quality of derived herbal products or for the discrimination of its most common substitute, V. chamaedrys L. (germander speedwell). In this study, we use DNA metabarcoding and high performance liquid chromatography coupled with mass spectrometry (HPLC-MS) to authenticate sixteen V. officinalis herbal products and compare the potential of the two approaches to detect substitution, adulteration and the use of unreported constituents. HPLC-MS showed high resolution in detecting phytochemical target compounds, but did not enable detection of specific plant species in the products. DNA metabarcoding detected V. officinalis in only 15% of the products, whereas it detected V. chamaedrys in 62% of the products. The results confirm that DNA metabarcoding can be used to test for the presence of Veronica species, and detect substitution and/or admixture of other Veronica species, as well as simultaneously detect all other species present. Our results confirm that none of the herbal products contained exactly the species listed on the label, and all included substitutes, contaminants or fillers. This study highlights the need for authentication of raw herbals along the value chain of these products. An integrative methodology can assess both the quality of herbal products in terms of target compound concentrations and species composition, as well as admixture and substitution with other chemical compounds and plants.

“…Many temperate plants that are now widely distributed across the Northern Hemisphere have been hypothesized to have originated in the Qinghai-Tibet Plateau (QTP) and adjacent regions and then migrated to other regions of the Northern Hemisphere [84][85][86][87][88]. Likewise, the tribe Veroniceae with nine genera and about 500 species has most likely originated in the QTP, with four of its genera restricted to this region [42,88,89]. West of the QTP, mountains of the Irano-Turanian region have been shown to act as a secondary center of speciation and diversification [90], so that numerous species groups, particularly xerophytes, originated and started their radiations there [3,[7][8][9][10][12][13][14][15][16][17]19,20,91].…”

Veronica subgenus Pentasepalae is the largest subgenus of Veronica in the Northern Hemisphere with approximately 80 species mainly from Southwest Asia. In order to reconstruct the phylogenetic relationships among the members of V. subgenus Pentasepalae and to test the “out of the Iranian plateau” hypothesis, we applied thorough taxonomic sampling, employing nuclear DNA (ITS) sequence data complimented with morphological studies and chromosome number counts. Several high or moderately supported clades are reconstructed, but the backbone of the phylogenetic tree is generally unresolved, and many Southwest Asian species are scattered along a large polytomy. It is proposed that rapid diversification of the Irano-Turanian species in allopatric glacial refugia and a relatively high rate of extinction during interglacial periods resulted in such phylogenetic topology. The highly variable Asian V. orientalis–V. multifida complex formed a highly polyphyletic assemblage, emphasizing the idea of cryptic speciation within this group. The phylogenetic results allow the re-assignment of two species into this subgenus. In addition, V. bombycina subsp. bolkardaghensis, V. macrostachya subsp. schizostegia and V. fuhsii var. linearis are raised to species rank and the new name V. parsana is proposed for the latter. Molecular dating and ancestral area reconstructions indicate a divergence age of about 9 million years ago and a place of origin on the Iranian Plateau. Migration to the Western Mediterranean region has likely taken place through a North African route during early quaternary glacial times. This study supports the assumption of the Irano-Turanian region as a source of taxa for neighboring regions, particularly in the alpine flora.
