Terpene lactones are prenol lipids containing a lactone ring. Fukinanolide is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Fukinanolide can be found in burdock and giant butterbur, which makes fukinanolide a potential biomarker for the consumption of these food products.
