title: 6α-Hy-droxy-5,6-dihydro-salviasperanol.
abstract: In the title compound, C(20)H(28)O(4), a diterpenoid isolated from the roots of Premna obtusifolia (Verbenaceae), the five-membered ring is in a half-chair conformation. One six-membered ring exists in a twisted-boat conformation while the other is in half-boat conformation. The crystal packing is stabilized by inter-molecular O-H⋯O and weak C-H⋯O inter-actions, generating (001) sheets.
