To study the chemical constituents of Phyllanthus emblica.
The chemical constituents were isolated and purified by silica gel, polyamide and Sephadex LH-20 chromatography. Their structures were elucidated by physicochemical proper- ties and spectral analysis.
13 compounds were isolated and identified as Triacontanol (1), Triacontanoic acid (2), β-Amyrin ke- tone (3), Betulonic acid (4), Daucosterol (5), Lupeol acetate (6), β-Amyrin-3-palmitate (7), Gallic acid (8), Betulinic acid (9), Ursolic acid (10), Oleanolic acid (11), Quercetin (12) and Rutin (13).
Compounds 1,2,4,6,7,9,10 and 11 are obtained from Phyllanthus emblica for the first time.
研究余甘子的化学成分。
采用硅胶、聚酰胺和葡聚糖凝胶LH - 20柱色谱法对化学成分进行分离纯化，并通过理化性质和光谱分析对其结构进行鉴定。
分离鉴定出13个化合物，分别为三十烷醇（1）、三十烷酸（2）、β-香树脂酮（3）、桦木酮酸（4）、胡萝卜苷（5）、乙酸羽扇豆酯（6）、β-香树脂醇-3-棕榈酸酯（7）、没食子酸（8）、桦木酸（9）、熊果酸（10）、齐墩果酸（11）、槲皮素（12）和芦丁（13）。
化合物1、2、4、6、7、9、10和11首次从余甘子中获得。
