“…The Verbascum L. (Scrophulariaceae) species are represented in the world with nearly 360 species [1]. In Turkey, the Verbascum genus consists of approximately 255 species, 200 of which are endemic (about 80% endemism rate) and it has 130 additional hybrid species [2].…”

The Verbascum genus includes many species used in folk medicine or the treatment of various diseases. In this study, the cytotoxic, antioxidant activity, and LC/MS-MS profiles of three Verbascum species, which are endemic in Eskişehir and its surroundings, were investigated. The cytotoxic effects of methanol extract of V.detersile, V. eskisehirensis, and V.gypsicola species on the cervical (HeLa) and ovarian cancer (SKOV-3) cells were investigated using a colorimetric assay. The results indicated that cytotoxic effect was not observed after treatment of SKOV-3 cells with Verbascum. On the other hand, the cytotoxic activity of V. detersile was found to be 0.1910 mg/dL and 1.057 mg/dL for HeLa cells after 24 or 48 hours incubation with V.detersile, respectively. The antioxidant activity was determined as 1,1-diphenyl-2-picrylhydrazyl (DPPH•) radical scavenging activity, trolox equivalent antioxidant capacity (TEAC assay), and also the total phenolic content of the samples was found. Total phenols were estimated as Gallic acid equivalents (GAE), expressed as mg Gallic acid/in 1g extract previously described by Singletton. LC/MS profiles separation and detection of phytochemicals of the extract were performed on a Shimadzu UPLC system consisting of a vacuum degasser, an autosampler (SIL20A Shimadzu Autosampler), a binary pump (LC20AD Shimadzu), an oven (CTO20A Shimadzu Column Oven) and DAD dedector (SPD M20A Shimadzu DAD Detector). In terms of antioxidant activity, V. gypsicola was found to have the least antioxidant activity among the three extracts, which is also correlated with the total amount of phenolic content in its content. In this way, it differs from other species. V. detersile exhibits a different chemical profile from the other two species with the iridoid catalpol derivatives it contains. Apigenin pentoside is the only flavonoid molecule detected in V. detersille.

“…It is represented by 257 species and 132 additional hybrids in Turkey, and has been divided into 13 artificial groups (Huber‐Morath 1978, Davis et al 1988).

Verbascum zerdust Fırat (Sect. Bothrosperma Murb.), is described as a new species from Bitlis province, Turkey. From a morphological point of view, the new species appears to be similar to Verbascum ponticum (Boiss.) Kuntze and Verbascum bornmuellerianum Hub.‐Mor., but it differs from both in several morphological features including plant height, indumentum, leaf and flower size, filament indumentum, seed and pollen morphology. A comprehensive description of the new species illustrated with detailed photographs, distribution map, habitat and ecology, vernacular name and IUCN conservation status is provided.
