The title furan-oditerpenoid, known as fibaruretin B (systematic name: 2β,3α-dihy-droxy-2,3,7,8α-tetra-hydro-penianthic acid lactone), C(20)H(24)O(7), 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 mol-ecules are linked into infinite chains along the c axis by O-H⋯O hydrogen bonds and weak C-H⋯O inter-actions.
标题呋喃-倍半萜类化合物，即黄藤素B（系统名称：2β,3α-二羟基-2,3,7,8α-四氢-翼萼木酸内酯），化学式为C(20)H(24)O(7)，是从黄藤的根中分离得到的。黄藤素B在2、3、4、4a、7、9、10a和10b位的绝对构型分别为S、R、S、R、S、S、S和S。在晶体结构中，分子通过O-H⋯O氢键和弱C-H⋯O相互作用沿c轴连接成无限链。
