Chalcones from Methanol Extract of Humulus Lupulus
Extracts of Humulus Lupulus yielded two known compounds, isoxanthohumol and xanthohumol, and two new chalcone derivatives, 3'-(isoprenyl)- 2',4 - dihydroxy - 4',6'- dimethoxychalcone and 2',6'-dimethoxy-4,4'-dihydroxychalcone. Their structures were established by spectral methods.
