Evidence Progesterone for first time, researchers have produced evidence that, a Mammalian steroid hormone, found in plants (J. Nat. Prod., DOI: 10.1021/np9007415).

 
 
There are so many groups - groups have shown that the presence of progesterone in the plant compounds that can be made from its predecessor is found in plants such as Mexican yam. While looking for a cytotoxic entity on walnut tree leaves, Guido F. Pauli of the University of Illinois, Chicago, and colleagues isolate and report the quantity of progesterone hormone is based on a combination of mass spectrometry and nuclear magnetic resonance techniques. In other plants, the team has found a new sulfate compounds such as progesterone.
"It raises fundamental questions about the biosynthesis of steroid-Can all plants make progesterone?" Said Pauli. In mammals, progesterone has several roles, such as uterine lining to prepare for potential pregnancy, but the biochemical role of progesterone in plants is not clear, which guarantees further research, he said.
"Even though we may think we know where the plant contains progesterone, Pauli and colleagues have proved definitively this as a case," said Charles L. Cantrell, a research chemist at the U.S. Department of Agriculture.
"I consider this as a major contribution to our knowledge of the biosynthesis of plant secondary metabolites," said David S. Seigler, who studied the bioactivity of the plants that produce compounds to the University of Illinois, Urbana-Champaign.
