Abstract
A study on the volatile oils of oleogum resin of Ferula sinkiangensis and F. fukanensis by use of GC-MS (CI/EI) showed the presence of twenty-six polysulfanes (disulfanes,
trisulfanes, thio-disulfanes, and di-disulfanes). The main component was sec-butyl-cis-1-propenyl disulfane in F. sinkiangensis, and sec-butyl-trans-1-propenyl disulfane in F. fukanensis. As minor components, seven new polysulfanes were detected in the oils for the first
time.
