Constituents of Aerial Parts from Erechtites hieraceiolia

A new oxygenated monoterpene (4) was isolated from the methanol extract of the aerial part of Erechtites hieraceiolia together with six known components, a dimethylheptane (1), three ionone derivatives (2,3 and 7) and two phenylpropanoids (5 and 6). Their structures were identified by means of physico-chemical and spectral data to be (2E, 5E)-6-hydroxy-2,6-dimethylhepta-2,4-dienal (1), 3(R)- hydroxy-5,6- epoxy-β-ionone (2), 3(R)-hydroxy-5,6-epoxy-β-ionol (3), (3E, 6E)-3,7- dimethylocta-3,5-dien-1,2,7-trios (4), 2-hydroxy4- (2-propenyl)phenyl- β-D -glucopvanoside (5), 2-methoxy-7(2-pnpenyl)phenyl -β-D -glucopyra- noside (6) and (6R,9R)-3-oxo-β-ionol-α-D -glucopyranoside (7).
