13-hydroxy-1,6,6,11,15-pentamethyl-14-(2,5,6-trihydroxy-6-methyl-3-oxoheptan-2-yl)tetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-7-ene-4,5,17-trione; 4,13-dihydroxy-1,6,6,11,15-pentamethyl-14-(2,5,6-trihydroxy-6-methyl-3-oxoheptan-2-yl)tetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadeca-3,7-diene-5,17-dione
Cucurbitacin k is a member of the class of compounds known as cucurbitacins. Cucurbitacins are polycyclic compounds containing the tetracyclic cucurbitane nucleus skeleton, 19-(10->9b)-abeo-10alanost-5-ene (also known as 9b-methyl-19-nor lanosta-5-ene), with a variety of oxygenation functionalities at different positions. Cucurbitacin k can be found in bitter gourd, which makes cucurbitacin k a potential biomarker for the consumption of this food product.
