Acer saccharum Marshall

(E/Z)-erythro-Guaiacylglycerol β-coniferyl ether is a lignan compound found in Canadian maple syrup. (E/Z)-erythro-Guaiacylglycerol β-coniferyl ether exerts antioxidant acyivity and can scavenge DPPH radica. (E/Z)-erythro-Guaiacylglycerol β-coniferyl ether can be used for the research of inflammation.

Cleomiscosin D is a natural product. Cleomiscosin D can be isolated from the wood of Acer saccharum (Aceraceae). Cleomiscosin D exhibits significant SOD-like activity with an IC₅₀ of 21.2 μM.

Erythro-guaiacylglycerol-β-O-4'-dihydroconiferyl alcohol was identified as one of the phenolic compounds isolated from Canadian maple syrup (MS-BuOH). It exhibited antioxidant properties along with other phenolic compounds and coumarins isolated from the syrup. These compounds showed varying degrees of antioxidant activity, with phenolic derivatives and coumarins showing superior activity, more so than lignans and flavonoids. This study marks the first time that 16 of the 23 phenolic compounds, including Erythro-guaiacylglycerol-β-O-4'-dihydroconiferyl alcohol, have been identified in maple syrup.
