从蜜柑草Phyllanthus matsumurae Hayata的干燥全草中共分得10个化合物。其中有4个黄酮、6个多酚类成分。作者报道4个黄酮化合物，经理化常数和光谱测定，分别鉴定为棚皮素-3-O-木精葡萄糖俄（Ⅰ），柳皮素-3-O-鼠李葡萄糖式（Ⅱ），槲皮素-3-O-葡萄糖甙（Ⅲ）和槲皮素（Ⅳ）。这些化合物均为首次从蜜柑草中分得。多酚类成分另报。

Four flavonoid compounds were isolated from Phyllanthus matsumurae. On the basis of physico-chemical properties and spectroscopic analysis，their structures were identified as quercetin-3-O-xyloglucoside(I)，quercetin-3-O-rhamnoglucoside(Ⅱ),quercetin-3-O-glucoside(Ⅲ)and quercetin(Ⅳ).All of them were isolated from this plant for the first time.
