Definition:A tetracyclic triterpenoid that is lanost-8-ene substituted by hydroxy groups at positions 3 and 25, a methylidene group at position 24 and an oxo group at position 7. Isolated from the whole plant of Silybum marianum, it exhibits inhibitory activity against chymotrypsin.
Synonyms:exact_synonym: (3beta)-3,25-dihydroxy-24-methylidenelanost-8-en-7-one
