A systematic screening of 170 different West Bengal plants was carried out to find antifungal antibiotics, using Aspergillus niger and Trichophyton rubrum as test organisms. From them, four plant species, viz. Curcuma zedoaria, C. aromatica, C. amada, and a Brassica sp. have been found to contain active antibiotic principles with strong inhibitory effects against both test organisms. © 1972 The New York Botanical Garden.
