The chloroform extract of Erigeron linifolius afforded two novel acety
lated pinene glucosides. Their structures were elucidated by 1D and 2D
NMR and FT-IR spectroscopy and mass spectrometry. The relative stereo
chemistry of the glucosides was established by a combination of coupli
ng constant analyses and NOESY. The glucosides showed high antimutagen
ic and low antimicrobial activities. (C) 1997 Elsevier Science Ltd. Al
