Asymmetric unit of (a) solvent-free 20-hydroxyecdysone, (2), (b) 20-hydroxyecdysone methanol solvate hydrate, (2)·MeOH·H2O, (c) 20-hydroxyecdysone trihydrate, (2)·3H2O and (d) polypodine B hydrate, (3)·H2O. H(—C) atoms are omitted for clarity. Solvent H-atom positions on (2)·3H2O were calculated to reflect probable hydrogen-bonding directions. Only main disorder components are shown.
