Study on Chemical Constituents of the Leaves of Canarium album (Lour.) Raeusch

Chemical constituents of the leaves of Canarium album (Lour.) Raeusch were studied.Eight compounds were isolated from ethylacetate extract of the leaf, and their structures were elucidated by various spectroscopic methods. They were identified as ethyl gallate(Ⅰ), scopoletin (Ⅱ), gallic acid (Ⅲ), amentoflavone (Ⅳ), myo-inositol (Ⅴ), quercetin (Ⅵ), β-sitosterol (Ⅶ) and 4,5-didehydro-chebulic acid triethyl ester(Ⅷ). Compound Ⅷ is a novel compound and compounds Ⅴ and Ⅵ were obtained from this genus of plant for the first time. Compounds Ⅳ and Ⅶ were isolated from this plant for the first time.
