A New Alkenylmethylresorcinol from the Fruits of Ardisia kivuensis.
2016
The phytochemical study of the MeOH extract from the fruits of Ardisia kivuensis was carried out using repeated silica gel column chromatography followed by Sephadex LH-20 to afford a new alkenylmethylresorcinol, ardisinol III (1) along with three known compounds, oleanolic acid, β-sitosterol and pentacosanoic acid. The structure of 1 was elucidated using spectroscopic analysis (NMR and MS), and comparison with published data. Compound 1 had weak antioxidant activity (IC50 109.8 μg/mL) while other compounds were not active as compared to L-ascorbic acid (IC50 3.9 μg/mL).
