Two new peroxyterpenyl coumarins including peroxyschininallylol [7-(3'
,7'-dimethyl-6'-hydroper oxyocta-2',7'-dienyloxy)-8-methoxy coumarin]
and peroxyschinilenol [7-(3',7'-dimethyl-7'-hydroper oxyocta-2',7'-die
nyloxy-8-methoxy coumarin] were isolated from the chloroform-soluble p
art of the root bark of Zanthoxylum schinifolium. The structures of th
ese compounds were elucidated by spectral analyses.
