(−)-ericanone or (−)-α-ericadione. From the spectroscopic data, the new structures were elucidated as (−)-(3S,7S)-ericanone 3-O-β-d-xylopyranoside, (−)-(3S,7S)-3″-hydroxyericanone 3-O-β-d-glucopyranoside, and (−)-(3S)-3″-hydroxy-α-ericadione 3-O-β-d-glucopyranoside respectively. In the 1H and 13C NMR spectra run in CD3OD, the latter metabolite was as (−)-α-ericadione 3-O-β-d-glucopyranoside, also found as a
