Perennial herb, 0.40-1m high, native to Europe, naturalized in North America; leaves pinnate; flowers white to pink.
„The main compound of both root oils is trans-epoxypseudoisoeugenyl tiglate, which is accompanied by several structurally related minor constituents, such as pseudoisoeugenyl tiglate and epoxypseudoisoeugenyl 2-methyl butyrate. Besides these characteristic phenylpropanoids, a number of sesqui- and tri-norsesquiterpenoids (C12-hydrocarbons) occur in appreciable amounts, whereas monoterpenoids could only be found in traces.“

„Leaf/root-differentiating callus cultures grew without growth regulators in a modified MS liquid medium. The capacity of callus to accumulate rare phenylpropanoids such as epoxypseudoisoeugenol tiglate (EPT), epoxy-anol tiglate (EAT) and anol tiglate (AT) was compared with that of seedlings and whole plants. Unorganized callus cultures failed to accumulate any phenylpropanoids, whereas the leaf/root-differentiating callus culture accumulated EPT. Leaves and roots contained 360 and 1000 µg EPT/g FW, respectively. The distribution of phenylpropanoids in different organs of the whole plant showed that EPT could be found in various organs (roots, leaves, fruits, stems, flowers, pedicels and ovaries) in amounts ranging from 0 (in fruits) to 10.7 mg/g FW (in roots). EAT and AT were present in fruits at concentrations of 7.0 and 5.3 mg/g FW, respectively. In seedlings, EPT occurred at concentrations of 0.4-0.7, 0.8-1.0 and 0.5-0.6 mg/g FW in roots, cotyledons and leaves, respectively.“
