title: [Studies on the chemical constituents of Desmodium styracifolium (Osbeck) Merr].
abstract: 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.
