Ochnaceae Extract

Ochnaflavone is an inhibitor of IIA-type secretory phospholipase A2 (sPLA2-IIA) with an IC₅₀ of 3.45 µM. Ochnaflavone exhibits significant anti-inflammatory and liver-protective effects, capable of inhibiting the degradation of phosphatidylethanolamine (PE) and lipid peroxidation induced by carbon tetrachloride (CCl4) in rat liver, with an IC₅₀ of 7.16 µM for lipid peroxidation. Ochnaflavone can be used in research on liver damage and inflammatory diseases.

(-)-Epigallocatechin-4'-O-methylether ((-)-EGC-4'-O-ME) is an orally active natural phenolic catechin with antioxidant, free radical-scavenging and hepatoprotective activities. (-)-Epigallocatechin-4'-O-methylether interferes with radiation-induced free radical formation, scavenges DPPH free radicals, inhibits carbon tetrachloride-induced increases in serum GOT and GPT, suppresses carbon tetrachloride-induced TBA-RS formation, and counteracts carbon tetrachloride-induced hepatocyte toxicity. (-)-Epigallocatechin-4'-O-methylether binds specifically to human serum albumin. (-)-Epigallocatechin-4'-O-methylether can be used in studies related to liver injury.

Mbamiloside A (compound 4), an isoflavonoid derivative, is a nature product that could be isolated form the stem heartwood of Lophira alata.
