Three new phenolic compounds, 5‐ O‐ ( β ‐apiosyl‐(1 → 2)‐ O‐β ‐xylopyranosyl)gentisic acid ( 1 ), 1‐ O‐ ( β ‐apiosyl‐(1 → 6)‐ O‐β ‐glucopyranosyl)‐3‐ O ‐methylphloroglucinol ( 2 ), and 15‐ O ‐( α ‐rhamnopyranosyl)aloe‐emodin ( 3 ), together with the known compound aloe emodin ( 4 ), were isolated from the stems of Spatholobus suberectus. Their structures were characterized by chemical and spectroscopic methods. The absolute configurations of the sugar units were not determined.
