A C-S-lyase preparation from ramson, ALLIUM URSINUM L., has been purified to apparent homogeneity. Separation techniques applied were hydrophobic interaction chromatography, anion exchange chromatography, and gel permeation chromatography. A 52-fold purification was obtained. The enzyme could be
From the chloroform extract of ALLIUM URSINUM L. (Liliaceae) bulbs, in addition to other sulfur-containing constituents ( E/Z)-4,5,9-trithiadeca-1,6,11-dien-9-oxide [= methylajoene) and ( E/Z)-4,5,9-trithiaocta-1,6-dien-9-oxide (= dimethylajoene) were isolated and identified by NMR and mass
