Lactones ofFerula gigantea

The following substances have been isolated from an acetone extract ofFerula gigantea B. Fedtsch.: a coumarin — umbelliferone, C₉H₆O₂, mp 230–233°C; and sesquiterpene lactones — talassin A, C₂₅H₃₀O₇, mp 188–191°C; malaphyllinin, C₂₄H₂₄O₇, mp 231–235°C; malaphyll, C₂₉H₃₂O₉, mp 212–213°C; and malaphyllin, C₂₆H₂₈O₉, mp 216–218°C. Structures have been proposed for three new sesquiterpene lactones on the basis of an analysis of their spectral characteristics.     

Lipids ofFerula seeds

A study has been made of the surface lipids and essential oil of the seeds of three species ofFerula: F. lapidosa, F. ceratophylla, andF. tschimganica. It has been shown that the surface lipids are characterized by a high content of saturated hydrocarbons, and a lipid extract of the seeds contained 50% of triacylglycerols.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR, Tashkent.

Terpenoids ofFerula lapidosa

The chemical compositions of the roots ofFerula lapidosa Korov from two growth sites have been studied, and an analysis of literature information has shown a dependence of the chemical composition of the plant on the growth site. A biogenetic interrelationship between germacrane, humulane, and carotane sesquiterpenoids is proposed.     

Esters ofFerula rubroarenose

Summary Three new esters, in addition to six known esters, have been isolated from the roots ofFerula rubroarenosa Eug. Kor. On the basis of chemical and spectral characteristics rubaferin, rubaferinin, and rubaferidin have been assigned the structures of isovanilloylborneol, and 8-vanilloyl- and 8-p-hydroxybenzoylugamdiol, respectively.Translated from Khimiya Prirodnykh Soedinenii, No. 6, pp. 712–715, November–December, 1978.
