In the course of our screening search for pollen growth regulators among fungal metabolites, using bioassay method with tea pollen grains, suitable for developing new herbicides and tools to analyze plant reproductive functions, we found the presence of pollen growth inhibitors in cultures of two fungi, Fusarium sp. and Aureobasidium sp.. Bioassay-guided fractionation led to isolation of the new active compounds and succeeded in the structure determination of fusanolide A and hydroxysulochrin. These compounds inhibited the growth of tea pollen tube at the concentration of 100 mg/l.
