Five diarylheptanoids including two new compounds were isolated from the rhizomes of Curcuma xanthorrhiza (Zingiberaceae).The structures of the new compounds were determined to be octahydrocurcumin ((3S, 5S)-1,7-bis(4-hydroxy-3-methoxyphenyl)-heptane-3,5-diol) (Ia) and (1ξ)-1-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)-6-heptene-3,5-dione (II) on the basis of spectral and chemical evidence.The absolute configurations of Ia and a new similar diarylheptanoid, (3R, 5R)-1-(4-hydroxyphenyl)-7-phenylheptane-3,5-diol (VIa), isolated from the rhizomes of Alpinia officinarum (Zingiberaceae), were established by application of the exciton chirality rule.Keywords--diarylheptanoid; Curcuma xanthorrhiza; Alpinia officinarum; Zingiberaceae; (3S, 5S)-1,7-bis(4-hydroxy-3-methoxyphenyl)-heptane-3,5-diol; (1ξ)-1-hydroxy-1,7-bis(4-hydroxy-3-methoxyphenyl)-6-heptene-3,5-dione; (3R, 5R)-1-(4-hydroxyphenyl)-7-phenylheptane-3,5-diol; exciton chirality rule; CD
