青橄榄叶的化学成分研究

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

摘要: 对橄榄科橄榄属青橄榄树叶子的化学成分进行了研究.从乙酸乙酯萃取部位分得8个化合物,经理化及光谱方法鉴定分别为:没食子酸乙酯(Ⅰ)、东莨菪素(Ⅱ)、没食子酸(Ⅲ)、穗花杉双黄酮(Ⅳ)、肌醇(Ⅴ)、槲皮素(Ⅵ)、β-谷甾醇(Ⅶ)、,5-去氢诃子裂酸三乙酯(Ⅷ).其中化合物Ⅷ为新化合物,化合物Ⅴ、Ⅵ为首次从该属植物中得到,化合物Ⅳ、Ⅶ为首次从该植物中得到.

Abstract: 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.
