IN THE TITLE COMPOUND [SYSTEMATIC NAME: 7,8-dimeth-oxy-11-methyl-17,19-dioxa-11-aza-tetra-cyclo-[12.7.0.0(4,9).0(16,20)]henicosa-1(21),4,6,8,14,16 (20)-hexaen-2-ol], C(21)H(25)NO(5), the benzene rings are inclined at a dihedral angle of 23.16 (5)°. One of the meth-oxy C atoms is close to coplanar with its attached ring [deviation = 0.129 (3) Å], whereas the other is orientated away from the ring [deviation = -1.124 (2) Å]. The 10-membered ring is highly puckered, and the OH and CH(3) substituents project to the same side of the ring. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into [010] chains and C-H⋯O and C-H⋯π inter-actions consolidate the packing.
在标题化合物[系统名称：7,8-二甲氧基-11-甲基-17,19-二氧杂-11-氮杂四环-[12.7.0.0(4,9).0(16,20)]二十一碳-1(21),4,6,8,14,16(20)-六烯-2-醇]，C(21)H(25)NO(5)中，苯环间的二面角为23.16(5)°。其中一个甲氧基碳原子与其相连的环接近共平面[偏差 = 0.129(3) Å]，而另一个则远离该环[偏差 = -1.124(2) Å]。十元环高度扭曲，OH和CH(3)取代基伸向环的同一侧。在晶体中，O—H⋯O氢键将分子连接成[010]链，C—H⋯O和C—H⋯π相互作用巩固了堆积。
