Abstract

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.
