Phenylethanoids are a type of phenolic compounds characterized by a phenethyl alcohol structure. Tyrosol and hydroxytyrosol are examples of such compounds.
Glycosides
The red deadnettle (
Lamium purpureum) contains phenylethanoid glycosides named
lamiuside A,
lamiuside B,
lamiuside C,
lamiuside D and
lamiuside E.
The aerial parts of
Stachys officinalis contain phenylethanoid
, (
betonyoside A,
betonyoside B,
betonyoside C,
betonyoside D,
betonyoside E and
betonyoside F). Chemical investigation of
methanol extracts from
Pithecoctenium crucigerum (Bignoniaceae) showed the presence of five phenylethanoid glycosides (
verbascoside,
isoverbascoside,
forsythoside B,
jionoside D and leucosceptoside B), these all active against
DPPH.
Verbascoside and echinacoside are phenylethanoid and phenylpropanoid hybrids forming ester bonds with sugars.
