PHENYLPROPANOID ESTERS FROM LAMIUM-ALBUM FLOWERS

Two phenylpropanoid glycosides, a new one, lamalboside (2(R)-galactosy lacteoside) and the known acteoside, the flavonol p-coumaroylglucoside , tiliroside, 5-caffeoylquinic acid (chlorogenic acid), along with rut oside and quercetin and kaempferol 3-O-glucosides were isolated from t he flowers of Lamium album. Esters of glycosides were obtained as mixt ures of trans/cis isomers. The presence of flavonoid p-coumaroylglucos ides links Lamium to other members of the subfamily Lamioideae.
