Abstract: Eleven compounds were isolated from the twigs and leaves of Rourea microphylla (Hook. et Arn) Planch. They were identified as quercetin-3-O-α-L-rhamnopyranoside (Ⅰ), hyperin (Ⅱ), quercetin (Ⅲ), astilbin (Ⅳ), β-sitosterol (Ⅴ), β-sitosteryl-β-D-glucopyranoside (Ⅵ), physcion (Ⅶ), erythroglaucin (Ⅷ), stearic acid (Ⅸ), palmitic acid (Ⅹ) and n-nonacosanane (Ⅺ) respectively, by means of UV, IR, NMR, MS spectra analyses and through chemical methods. The compounds Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅵ, Ⅶ, Ⅷ, Ⅸ, Ⅹ and Ⅺ were first reportedin the Rourea genus.

Key words: Rourea microphylla (Hook. et Arn) Planch, Hyperin, Erythroglaucin.
