The amyrins are three closely related natural chemical compounds of the triterpene class. They are designated α-amyrin (ursane skeleton), β-amyrin (oleanane skeleton), and δ-amyrin. Each is a pentacyclic triterpenol with the chemical formula C30H50O. They are widely distributed in nature and have been isolated from a variety of plant sources such as epicuticular wax. In plant biosynthesis, α-amyrin is the precursor of ursolic acid and β-amyrin is the precursor of oleanolic acid. All three amyrins occur in the surface wax of tomato fruit. α-Amyrin is found in dandelion coffee.

Distigmine (as distigmine bromide) is a parasympathomimetic. Distigmine is similar to pyridostigmine and neostigmine but has a longer duration of action. It is available as tablets on prescription only. It is commonly used to treat various conditions, including myasthenia gravis and underactive bladder. Distigmine has a greater risk of causing cholinergic crisis because of accumulation of the drug being more likely than with neostigmine or pyridostigmine and so distigmine is rarely used as a treatment for myasthenia gravis, unlike pyridostigmine and neostigmine.

This 27-carbon biomarker is produced by diagenesis of cholesterol and is one of the most abundant biomarkers in the rock record. Presence of cholestane, its derivatives and related chemical compounds in environmental samples is commonly interpreted as an indicator of animal life and/or traces of O2, as animals are known for exclusively producing cholesterol, and thus has been used to draw evolutionary relationships between ancient organisms of unknown phylogenetic origin and modern metazoan taxa.
