Abstract: Two new compounds orizalanasterolide A and B identified as lanast-1,11, 22-trien-3β, 9α-diol-18-al-21(24)-olido-3β-D-glucopyranoside 1, lanast-1, 11, 22-trien-3β, 9α-diol-18-al-21(24)-olido-3β-D-glucopyranosyl-(1'-4')-β-D-glucopyranoside 2, have been isolated from the rice hulls of Oryza sativa. Their structures have been elucidated with the help of 500/125 MHz NMR using 1D and 2D spectral methods viz: ¹H and ¹³C NMR, ¹H-¹H COSY,¹H-¹³C HETCOR and DEPT aided by EIMS, FABMS and IR spectroscopy.
