The results of a biomechanical study of the generic relationships of Astragalus and Oxytropis are presented.

Dried plant materials was hydrolyzed in 2 N hydrocholoric acid, the hydrolysates were extracted with n-amyl alchol, and chromatographed in two dimenstions using thin layer chromatography (TLC). The patterns and the RF values of the "spots" separated were recorded and analysed.

The flavonoid patterns for all the plant organs studied were similar and no definite relationships between the flavonoid patterns and morphological characters could be ascertained. The flavonoid patterns exhibited by the members of both taxa indicate that the present means of morphological separation of this plant complex into two genera may not be valid.
