[Fungal activity of various alkaloids isolated from Catharanthus roseus G. Don].
Evaluation is made of the fungal activity of ajmalicine, aparacine, catarantine, reserpine, tetrahydroalstonine, vincubine, vindoline and vindolinina--alkaloids isolated from C. roseus growing in Cuba--on new fungi strains and yeasts which include some of human clinical interest. The method employed was the diffusion in an agar mean with sections or cylinders containing solutions of the alkaloids at 2% and 3% concentrations. The best results are obtained with an aparicine base, while tetrahydroalstonine, vincubine and vindolinine solutions did not inhibit the growth in any of the germs tested.
