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.

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,...
