A new molecular study shows that a compound called perrotetinene in certain species of liverworts is actually a psychoactive cannabanoid.
From Science News:
A group of Japanese scientists in 1994 discovered perrotetinene in liverworts but the new study is the strongest evidence yet that the compound is a psychoactive cannabinoid.
Previously cannabis was the only plant known to produce such cannabinoids….
After mapping perrotetinene’s molecular structure the researchers created a synthetic version and tested it on mice.
The results suggested that perrotetinene may be slightly less psychoactive than THC – says study coauthor Jürg Gertsch – a biochemist at the University of Bern in Switzerland.
The liverwort compound may also have fewer negative side effects such as memory loss and loss of coordination – he says.
