A new bisabolene derivative (1S∗, 2R∗, 4R∗, 7R∗, 1 0R∗)-1,7,10,11-tetrahydroxy-1,7,11-trimeth- yl-4,10(H)-2-O-cinnamoyl-bisabol-8(9)-ene (1), together with cinnamic acid (2), methyl cinnamate (3), sodium cinnamate (4) and methyl elaidate (5) have been isolated from the leaves and barks ofFissistigma petelotii. Sodium cinnamate (4) was isolated for the first time from the nature. The structures of these compounds were elucidated by analysis of their IR, MS, 1D and 2D NMR spectra.

Key words: Fissistigma petelotii, Bisabolene, Cinnamic Acid, Methyl Cinnamate, Sodium Cinnamate, Methyl Elaidate
