C17H22O4 (290.1518012)


Tulipinolide belongs to germacranolides and derivatives class of compounds. Those are sesquiterpene lactones with a structure based on the germacranolide skeleton, characterized by a gamma lactone fused to a 1,7-dimethylcyclodec-1-ene moiety. Tulipinolide is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Tulipinolide can be found in sweet bay, which makes tulipinolide a potential biomarker for the consumption of this food product.

   

Hypochoeroside A

9-hydroxy-3,6,10-trimethyl-4-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-2H,3H,3aH,4H,5H,8H,9H,11aH-cyclodeca[b]furan-2-one

C21H32O9 (428.2046222)


Hypochoeroside a belongs to germacranolides and derivatives class of compounds. Those are sesquiterpene lactones with a structure based on the germacranolide skeleton, characterized by a gamma lactone fused to a 1,7-dimethylcyclodec-1-ene moiety. Hypochoeroside a is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Hypochoeroside a can be found in endive, which makes hypochoeroside a a potential biomarker for the consumption of this food product.
