%X One new rare carbon-bridged citrinin dimer quinocitrindimer C (1) as a pair of epimers, two new polyketide penicilliodes D (3) and E (4) together with nine known citrinin derivatives, were isolated from the fermentation broth of starfish-derived symbiotic fungus Penicillium sp. GGF16-1-2. Their structures and configurations were elucidated by comprehensively spectroscopic data analysis and electronic circular dichroism calculations. Eleven citrinin derivatives were tested by Colletotrichum gloeosporioides, and compound 2 played a significant antifungal activity against Colletotrichum gloeosporioides with LC50 value of 0.27 μg/ml.
