Lysergic acid hydroxyethylamide , LSH for short , is an ergot alkaloid , the chemical structure of which is similar to that of LSD and especially that of lysergic acid ethylamide.

Occurrence and history

The D -lysergic acid derivative LSH occurs in various mushrooms and bindweed plants. It was first discovered in 1960 in the fungus Claviceps paspali . In 1963 it was found that this also occurs in well-known psychoactive bindweed plants (in the seeds, as well as partly in the plant itself).

According to Albert Hofmann, it is one of the main active ingredients in these psychoactive bindweed plants. It is synthesized by symbiotic fungi on the plants (with ergometrine as a precursor / intermediate stage). In aqueous and, above all, alkaline ambient conditions, it breaks down into ergine (LSA) and acetaldehyde , which is why, according to Hofmann, it is easily decomposed into LSA in the course of an extraction process, and which is probably one of the reasons why Hofmann did not originally discover it.

Fresh seeds of the bindweed (as well as partly the plant itself) have a large proportion of LSH, which breaks down into LSA over time until only LSA is present in older seeds. Some analysis methods (e.g. mass spectrometers ) also partially decompose it.

effect

There are no known attempts on humans. Tests on animals showed that LSH could have effects similar to LSD.
