C37H43N3O12 (721.2847)


Trihydroxyferuloyl spermidine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Trihydroxyferuloyl spermidine can be found in a number of food items such as small-leaf linden, rye, swamp cabbage, and rape, which makes trihydroxyferuloyl spermidine a potential biomarker for the consumption of these food products.
