Common Name5,6-dihydroxy-6-(2-hydroxy-3a,6,6,9b,11a-pentamethyl-10-oxo-7-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-1h,2h,3h,3bh,4h,7h,8h,9h,9ah,11h-cyclopenta[a]phenanthren-1-yl)-2-methylheptan-2-yl acetate
Description(3B,16a,20R)-25-Acetoxy-3,16,20,22-tetrahydroxy-5-cucurbiten-11-one 3-glucoside belongs to the class of organic compounds known as cucurbitacin glycosides. These are polycyclic compounds containing a carbohydrate derivative glycosidically linked to a curcubitane nucleus (3b,16a,20R)-25-Acetoxy-3,16,20,22-tetrahydroxy-5-cucurbiten-11-one 3-glucoside is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, (3b,16a,20R)-25-acetoxy-3,16,20,22-tetrahydroxy-5-cucurbiten-11-one 3-glucoside has been detected, but not quantified in, fruits. 5,6-dihydroxy-6-(2-hydroxy-3a,6,6,9b,11a-pentamethyl-10-oxo-7-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-1h,2h,3h,3bh,4h,7h,8h,9h,9ah,11h-cyclopenta[a]phenanthren-1-yl)-2-methylheptan-2-yl acetate is found in Cyclanthera pedata. This could make (3b,16a,20R)-25-acetoxy-3,16,20,22-tetrahydroxy-5-cucurbiten-11-one 3-glucoside a potential biomarker for the consumption of these foods.
