Amelioration by Idesia polycarpa Maxim. var. vestita Diels. of Oleic Acid‐Induced Nonalcoholic Fatty Liver in HepG2 Cells through Antioxidant and Modulation of Lipid Metabolism

Oxidative Medicine and Cellular Longevity, Volume 2020, Issue 1, 2020., 2020
Idesia polycarpa Maxim. var. vestita Diels (I. polycarpa) is well known as an edible oil plant which contains abundant linoleic acid and polyphenols. The objective of this study was to maximize the by‐product of defatted fruit of I. polycarpa. We found that the fraction D of ethyl acetate extract (EF‐D) contained more polyphenols, which contribute to ...
