A new α-tetralone derivative designated (-)-regiolone has been isolated with juglone, betullic acid and sitosterol from the stem-bark of Juglans regia. (-)-Regiolone has been shown to be 4,8-dihydroxy-1-tetralone on the basis of its spectral data and chemical transformation to juglone.Its conformation has been deduced from the 1H NMR spectral data.The absolute stereochemistry of its only chiral centre has been shown to be S by the application of the dibenzoate chirality rule.
