N2 - Osajin [systematic name: 5-hydroxy-3-(3-hydroxyphenyl)-8,8-dimethyl-6-(3-methylbut-2-enyl)-4H,8H-pyrano[2,3-h]chromen-4-one, C25H24O5, crystallizes with two independent molecules in the asymmetric unit. The benzopyranone ring system is nearly planar in both molecules and they differ significantly only in the orientation of the benzene rings, which are rotated by 56.27 (7) and 44.16 (7)deg. with respect to the benzopyranone systems. In the crystal structure, intermolecular O-H...O hydrogen bonds link the molecules into dimers.
