[Chemical Constituents from Macaranga denticulata Root].

OBJECTIVE: To study the chemical constituents from Macaranga denticulata Root. METHODS: The chemical constituents were isolated and purified by silica-gel column chromatography and recrystallization, and their structures were identified by physicochemical properties and spectral data. RESULTS: Nine compounds were isolated and identified as: gheddic acid (1), aleuritolic acid-3-acetate (2), β-sitosterol (3), stigmast-4-en-6β-ol-3 -one (4), 2α-hydroxyaleuritolic acid 3-p-hydroxybenzoate (5), scopoletin (6), daucosterol (7), 2, 6-dimethoxy-1,4-benzoquinone (8) and maslinic acid(9). CONCLUSION: Compounds 1-9 are obtained from this plant for the first time.
