目的：分离鉴定乌藤中化学成分。方法：采用各种色谱法进行分离，运用多种波谱方法鉴定化合物结构。结果：分离并鉴定了7个化合物，分别是乌藤素 C(1)，β senepoxide(2)，2,4 二羰基六氢 1,3 二氮杂卓(3)，山柰酚 3,7 O α L 二鼠李糖苷(4)，安诺洛宾(anolobine，5)，(-) lyoniresinol(6)和schizandriside(7)。结论：化合物1是新化合物，化合物2～7为首次从该植物中分离得到。
Objective: To isolate and identify chemical constituents of Uvaria tonkinensis var. subglabra. Method: The column chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis including 1D and 2D NMR, IR and MS techniques. Result: Seven compounds were isolated and identified as subglain C (1), β senepoxide (2), 2, 4 dioxohexahydro 1, 3 diazepin (3), kaempferol 3, 7 di O α L rhamnoside (4), anolobine (5), (-) lyoniresinol (6) and schizandriside (7). Conclusion: Compound 1 was the new natural product; compounds 2 7 were isolated for the first time from U. tonkinensis var. subglabra.
