A new alkaloid, named desmodimine, C12H15NO4, gum, and a new natural product, named desmodilactone, C8H13NO3, mp 84-85 degrees C have been isolated from the aerial parts of Desmodium styracifolium (Osbeck) Merr. belonging Leguminosae. On the basis of spectral analysis their structures were deduced as formula I and II. In addition, lupenone (III), lupeol (IV), tritriacontane (V), stearic acid (VI), eicosanoic acid eicosyl ester (VIII) and beta-sitosterol (VII) were isolated for the first time from this plant.
从豆科植物广金钱草（Desmodium styracifolium (Osbeck) Merr.）的地上部分分离出一种新生物碱，命名为金钱草碱（desmodimine），化学式为C12H15NO4，呈胶状，以及一种新天然产物，命名为金钱草内酯（desmodilactone），化学式为C8H13NO3，熔点84 - 85摄氏度。基于光谱分析，推断它们的结构分别为式I和式II。此外，首次从该植物中分离出羽扇豆酮（lupenone，III）、羽扇豆醇（lupeol，IV）、三十三烷（tritriacontane，V）、硬脂酸（stearic acid，VI）、二十烷酸二十烷基酯（eicosanoic acid eicosyl ester，VIII）和β-谷甾醇（beta-sitosterol，VII）。
