Sultan Qaboos University
In 2006, researchers of Oman's Sultan Qaboos University published their findings from a chemical investigation into the leaves in which they found it contained semiglabrin, semigalbrinol, and a new flavanone named apollineanin. One 2014 study revealed that pseudosemiglabrin extracted from the aerial parts of "Tephrosia apollinea" had an antiproliferative effect on cancer cell lines.
