Chemical investigation of ceylonese plants. Part III. Extractives of the fruits of Argyreia populifolia choisy (convolvulaceae)
Abstract
From the light petroleum extractives of the fruits of Argyreia populifolia Choisy, friedelin, friedelan-3β-ol, octacosan-1-ol, β-sitosterol, a new ester [stearyl 4-hydroxycinnamate (I)], and an unidentified ester have been isolated. Stearyl 4-methoxycinnamate (II) has been synthesised and shown to be identical with the methyl ether of the natural ester (I).
