From the petrol extract of the aerial parts of Tribulus cistoides three steroid sapogenins and two N-acyltyramines were isolated, whereas the methanolic extract gave nine steroid saponins, among them the cardioactive cistocardin, saponin-3, saponin-4 and saponin-7. Furthermore, a furostanol diglycoside was isolated besides 5'-(hydroxysulphonyloxy) jasmonic acid, D-(+)-pinitol and sucrose. The structures were established by spectroscopic investigations of the isolated compounds and their hydrolysis products. 5'-(Hydroxysulphonyloxy) jasmonic acid has been prepared by partial synthesis.
