A new globoscinic acid derivative, aspertubin A (1) along with four known compounds, were obtained from the co-culture of Aspergillus tubingensis S1120 with red ginseng. The chemical structures of compounds were characterized by using spectroscopic methods, the calculated and experimental electronic circular dichroism. Panaxytriol (2) from red ginseng, and asperic acid (4) showed significant antifeedant effect with the antifeedant rates of 75 % and 80 % at the concentrations of 50 μg/cm .

- Eight new compounds (1-8) were discovered from a fungus associated with an edible mushroom, using the OSMAC strategy, with Triharzianin A (1) being the first characterized compound featuring a C-prostaglandin skeleton.
- Through various methods, including Mosher's and ECD spectra analysis, the configurations of several compounds were determined, and most showed significant attraction to silkworms, with rates between 30-90%.
- Compound 7 exhibited anti-AChE activity and insecticidal potential, while compounds 2, 3, and 7-11 demonstrated antifungal properties against specific fungi, highlighting their potential for biological control in agriculture.
