TWO FURTHER BIS-INDOLE ALKALOIDS FROM TABERNAEMONTANA BOVINA

The new bis-indole alkaloids tabernaemontabovine (1) and tabernaemontavine (2) have been isolated from aerial parts ofTabernaemontana bovina. Their structures have been assigned on the basis of APT, 1H-1H DQF COSY, gradient-selected HSQC and gradient-selected HMBC-spectra.
