摘要：

Objective: To study the chemical constituents and antitumor activities of H-NMR, 13C-NMR and EI-MS. The trypan blue experiments -hydroxy-30-norlupan-20-one (5), (2, 3)-3, 5, 7, 4′-tetrahydroxy flavanone (6), kaempferol (7), 5, 7, 4′-trihydroxy flavanone (8), quercetin (9) and daucosterol (10). Conclusion: Compounds 1, 2, 5 and 8 were isolated from this genus for the first time. The trypan blue experiments in vitro showed that compounds 1, 4 and 5 had growth inhibitory effects on HL-60 cells.
