The title furanoditerpenoid, known as fibaruretin B (systematic name: 2 beta,3 alpha-dihydroxy-2,3,7,8 alpha-tetrahydropenianthic acid lactone), C20H24O7, was isolated from the roots of Arcangelisia flava. The absolute configurations at positions 2, 3, 4, 4a, 7, 9, 10a and 10b of fibaruretin B are S, R, S, R, S, S, S and S, respectively. In the crystal structure, the molecules are linked into infinite chains along the c axis by O-H center dot center dot center dot O hydrogen bonds and weak C-H center dot center dot center dot O interactions.
