were isolated from the roots of Verbascum lasianthum Boiss. ex Bentham. In addition, 2 phenylethanoid glycosides, verbascoside {=acteoside, [β-(3,4-dihydroxyphenyl)-ethyl]-(3′-O-α-L-rhamnopyranosyl)-(4′ O-caffeoyl)-β-D-glucopyranoside} (4) and poliumoside {= [β-(3,4-dihydroxyphenyl)-ethyl]-(3′,6′-O-αL-dirhamnopyranosyl)-(4′ -O-caffeoyl)-β-D-glucopyranoside} (5), were also isolated. The structur...

Studies were conducted on three herbaceous plant species growing in naturally high solar UV environments in the subalpine of Mauna Kea, Hawaii, USA, to determine if diurnal changes in epidermal UV transmittance (T(UV)) occur in these species, and to test whether manipulation of the solar radiation regime could alter these diurnal patterns. Additional field studies were conducted at Logan, Utah,...

New nothospecific names were created for six Verbascum hybrids which previously described by Murbeck without binomials: ?ipecensis (V. baldaccii ? V. phlomoides), ?krusevacense abietinum ?lundense herzogii leucophyllum), ?petrovicii heuffelii speciosum), ?soskae pulverulentum), ?soskicii longifolium var. pannosum nicolai).

The illustrated information on identification, distribution, specimens examined, habitat, conservation status, phenology, etymology, taxonomic notes.

Verbascum thapsus is naturally grown in the Himalayas and widely used herbal teas traditional medicine for its anticarcinogenic anti-inflammatory properties. The present study was designed to majority of leaf extracts from thapsus. All were analysed phytochemical properties, antioxidant capacity antimicrobial potential against both Gram-positive Gram-negative bacteria. Biochemical investigation...

The anti-inflammatory and antinociceptive properties of four major compounds from the flowers of Verbascum pterocalycinum var. mutense were investigated. Saponin glycosides called ilwensisaponin A and C and iridoid glycosides known as ajugol and picroside IV were isolated from the methanolic extract. A dose-related anti-inflammatory and antinociceptive response were obtained in this study at do...
