Abstract

From Tarchonanthus camphoratus L., the authors isolated a new quaternary alkaloid tarchonanthine (I) and five flavones, viz. 5,​7,​4'-​trihydroxy-​6-​methoxyflavone (hispedulin)​, apegenin, 5,​3',​4'-​trihydroxy-​6,​7-​dimethoxyfavone, 5,​7,​3',​4'-​tetrahydroxy-​6-​methoxyflavone (nepetin)​, and luteolin.  The structure of these components was established through spectral studies.  All of the flavones were reported for the first time from the genus Tarchonanthus.
