protodioscin
Sign in to saveProtodioscin is a steroidal saponin compound found in a number of plant species, most notably in the Tribulus, Trigonella Dioscorea and Trillium families. It is best known as the putative active component of the herbal aphrodisiac plant Tribulus terrestris.

Protodioscin is a steroidal saponin compound found in a number of plant species, most notably in the Tribulus, Trigonella Dioscorea and Trillium families. It is best known as the putative active component of the herbal aphrodisiac plant Tribulus terrestris.
Extracts of T. terrestris standardized for protodioscin content have been shown to produce proerectile effects in isolated tissues and aphrodisiac activity in several animal models. Protodioscin is thought to contribute to increased androgen receptor immunoreactivity in some tissues, likely as a secondary effect of elevated levels of endogenous androgens such as testosterone and dihydrotestosterone (DHT). This increase in androgen receptor immunoreactivity has been observed after administration of Tribulus terrestris extracts, but current evidence does not support the view that protodioscin acts primarily or directly by raising the density of androgen receptors; instead, it may enhance androgen receptor expression indirectly through its influence on androgen levels.
