Other claims from this paper (8)
- Mechanism The higher cytotoxicity of fresh-leaf extracts was attributed, as likely, to higher cyanogenic glycoside content.
- Observation Extracts of the India and Paraguay Moringa ecotypes were characterised by high levels of quercetin derivatives and caffeic acids.
- Intervention effect Extracts from the India and Paraguay ecotypes (and the Just Moringa powder) significantly inhibited LPS-induced nitric oxide production in macrophages (p < 0.05).
- Intervention effect Just Moringa and Paraguay extracts reduced iNOS gene expression (p < 0.05 and p < 0.01, respectively).
- Intervention effect Only the Paraguay extract decreased iNOS protein levels (p < 0.05).
- Intervention effect Quercetin-3-O-glucoside and rutin showed significant effects only at concentrations approximately 100-fold higher than those present in the extracts.
- Association The authors conclude that ecotypic variation strongly affects the polyphenolic composition and anti-inflammatory properties of MO leaves.
- Recommendation The authors recommend reporting both the origin and the phytochemical composition in MO-based products.
