Five new compounds, including four C(17) gamma-lactones, dihydroisoobtusilactone (1), dihydroobtusilactone (2), 3-epilitsenolide D(2) (3), and 3-epilitsenolide D(1) (4), and one furanone alseodafuranone (5), were isolated from the root and stem of Alseodaphne andersonii. Their structures were elucidated mainly by spectral analysis (NMR and MS) and partially by chemical correlation.
从毛叶琼楠的根和茎中分离出5个新化合物，包括4个C(17)γ-内酯，即二氢异钝叶内酯（1）、二氢钝叶内酯（2）、3-表刺桐烯醇内酯D(2)（3）和3-表刺桐烯醇内酯D(1)（4），以及1个呋喃酮类化合物毛叶呋喃酮（5）。它们的结构主要通过光谱分析（核磁共振和质谱）确定，部分通过化学关联确定。
