Crystals of the title compound, C(22)H(29)NO(5)·C(4)H(8)O(2), {[systematic name: (2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-butyl-tetra-hydro-6-methyl-2,5-methano-4,3,8a-[1]propan-yl[3]yl-idene-furo[3,2-f][1,4]oxazepin-7(5H)-yl-idene]-4-meth-oxy-3-methyl-furan-2(5H)-one ethyl acetate solvate} were isolated from the root extracts of Stemona aphylla (Stemonaceae). The structure closely resembles those of stemofoline derivatives which have previously been reported. Inter-molecular contacts are observed between some C-bonded H atoms and nearby O atoms, perhaps indicating weak inter-actions which could influence the packing of species within the unit cell.
标题化合物C(22)H(29)NO(5)·C(4)H(8)O(2) {[系统名称：(2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-丁基-四氢-6-甲基-2,5-亚甲基-4,3,8a-[1]丙烷亚基[3]亚基-呋喃并[3,2-f][1,4]恶唑并[7(5H)-亚基]-4-甲氧基-3-甲基-呋喃-2(5H)-酮]乙酸乙酯溶剂合物} 的晶体是从无叶百部（百部科）的根提取物中分离得到的。其结构与先前报道的百部碱衍生物的结构非常相似。在一些与碳相连的氢原子和附近的氧原子之间观察到分子间接触，这可能表明存在弱相互作用，这种相互作用可能会影响晶胞内物质的堆积。
