Xanthoangelol C

(4E)-6-{2,6-dihydroxy-3-[(2E)-3-(4-hydroxyphenyl)prop-2-enoyl]phenyl}-4-methylhex-4-enal

C22H22O5 (366.1467162)


Xanthoangelol c is a member of the class of compounds known as 3-prenylated chalcones. 3-prenylated chalcones are chalcones featuring a C5-isoprenoid unit at the 3-position. Thus, xanthoangelol c is considered to be a flavonoid lipid molecule. Xanthoangelol c is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Xanthoangelol c can be found in angelica, which makes xanthoangelol c a potential biomarker for the consumption of this food product.
