lysergic

1. (not comparable, organic chemistry) Used in the designation of lysergic acid and lysergic acid diethylamide: produced by hydrolysis from ergot.Examples: "Much more soluble in water than ergotoxine, ergotamine, sensibamine or ergoclavine, and is thought to be the hydroxyisopropylamide of lysergic acid."; "In a series of papers during the past few years Jacobs and [Lyman C.] Craig have shown that the ergot alkaloids are derivatives of a unique acid base, lysergic acid, in which the latter or an isomer is conjugated with certain amino acids or substances which can be derived from them, such as 2-aminopropanol-1, pyruvic acid, and isobutyrylformic acid. Since lysergic acid is thus the common characteristic constituent of these alkaloids, the determination of its structure became at once a major issue in the ergot alkaloid problem."; "In 1938, while experimenting with derivatives of ergot, a Swiss chemist named Hoffman^([sic – meaning [Albert] Hofmann]) first produced the drug, Lysergic Acid Diethylamide, by adding a diethylamide group onto lysergic acid."not-comparableusually

2. (comparable) Psychedelic, trippy.Examples: "The Doves' mantras of desolation are even trippier than the first couple Cranes records (though maybe not as lysergic as prime Swans or Ravens), […]"; "As mentioned earlier, my first impression of the sleeve art was that it bore marked similarity to a poetry collection – nothing very lysergic about that."; "On the evidence of this lysergic dish – blobs and pools of strident oddness, especially the mozzarella-topped gelée that tastes like the stuff left at the bottom of olive tins topped with organic foaming facewash – [David] Shrigley's better off sticking to the art."comparablenot-comparableusually
