Fund Project: The authors wish to thank Ms.Li Shen and Ms.Fengmei Zhou (School of Pharmacy,Yantai University) for UV,IR and NMR testing,and Prof.Shaoxiang Xiong (Institute of Chemistry,Chinese Academy of Sciences) for the measurement of EIMS and HREIMS.

Two new indole alkaloids, 4-oxo-4, 12-dihydroindolo[2, 3-a]quinolizine-3-carbaldehyde (1) and 1, 6, 7-trihydro-indolo-[2, 3-a]furan[3, 4-g]quinolizine-3, 4 (13H)-dione (2), were isolated from Nauclea officinalis. Their structures were determined on the basis of 1D and 2D NMR spectral data.
- Nauclea officinalis,
- Indole alkaloids,
- Indolo[2,3-a]quinolizine,
- Indolo[2,3-a]furan[3,4-g]quinolizine
