AI Article Synopsis
- Scientists looked at the flowers and seeds from a plant called Loureiro Merrill to see how good they are at fighting harmful stuff in the body, like free radicals and inflammation.
- They found that almost all parts of the plant, except for one type of extract, had strong abilities to act against these harmful substances.
- The flowers were especially good at reducing inflammation, and the study suggests that this plant could be useful for health purposes.
Article Abstract
This study explored, for the first time, the antioxidant (total antioxidant content, reducing power, ferric ion reducing antioxidant power, hydroxyl radical scavenging, ferrous ion-chelating assays), anti-tyrosinase, anti-inflammatory properties, and hepatoprotective effect in HepG2 cell lines of (Loureiro) Merrill flowers and seeds. All extracts except -hexane exhibited significant antioxidant activity, with high levels of tannin and proanthocyanidins. Luteolin (), 6-,-dimethylallylkaempferol7---d-glucopyranoside (), 6-,-dimethylallylquercetin7---d-glucopyranoside (), and 6-,-dimethylallyldihydrokaempferol 7---d-glucopyranoside () were isolated using semi-preparative HPLC. Compounds - demonstrated good anti-tyrosinase activity. The most active hepatoprotective extracts were found to be aqueous extracts. The flower extracts exhibited greater anti-inflammatory properties by the decrease of NO in RAW 264.7 cells and bovine serum albumin protein. Among them, the -hexane and EtOAc extracts from flowers displayed promising anti-inflammatory activity. This was predicted by analysis of -. In summary, appears to be a promising natural source for antioxidant, anti-tyrosinase, and anti-inflammatory applications.
