The title compound, C(22)H(32)O(7), a natural ent-kaurane diterpenoid also referred to as Maoyecrystal F, was obtained from the medicinal plant Isodon nervosa. There are four rings with the expected cis and trans junctions. Cyclohexane ring A adopts a chair conformation, rings B and C adopt boat conformations, while the five-membered ring has an envelope conformation. The mol-ecules stack along the a axis in the crystal and are linked together by inter-molecular O-H⋯O hydrogen bonds.
标题化合物C(22)H(32)O(7)，一种天然的对映-贝壳杉烷二萜类化合物，也被称为毛叶结晶F，是从药用植物显脉香茶菜中获得的。它有四个具有预期顺式和反式连接的环。环己烷环A呈椅式构象，环B和环C呈船式构象，而五元环呈信封式构象。分子在晶体中沿a轴堆积，并通过分子间O-H⋯O氢键连接在一起。
