WebPenicillium digitatum has been cultured on citrus fruits and yeast extract sucrose agar media (YES). Cultivation of fungal cultures on solid medium allowed the isolation of two novel tryptoquivaline-like metabolites, tryptoquialanine A (1) and tryptoquialanine B (2), also biosynthesized on citrus fruits. Web64 It was demonstrated that tryptoquialanine A (TA), purified from P. digitatum extracts, was 65 phytotoxic, showing herbicidal activity against Citrus sinensis seeds in a germination assay (Costa et 66 al. 2024).
