Isolation and characterization of leaf volatiles in Anemopsis californica (Nutt.) Hook. and Arn. (A.californica) was performed using steam distillation, solid-phase microextraction, and supercritical fluidextraction. Thirty-eight compounds were detected and identified by gas chromatography; elemicinwas the major component of the leaf volatiles. While the composition of the leaf volatiles varied withmethod of extraction, 
fchars/alpha.gif" BORDER=0>-pinene, sabinene, fchars/beta2.gif" BORDER=0 ALIGN="middle">-phellandrene, 1,8-cineole, piperitone, methyl eugenol,(E)-caryophyllene, and elemicin were usually present in readily detectable amounts. Greenhouse-reared clones of a wild population of A. californica had an identical leaf volatile composition with theparent plants. Steam-distilled oil had antimicrobial properties against 3 (Staphylococcus aureus,Streptococcus pneumoniae, and Geotrichim candidum) of 11 microbial species tested. Some of thisbioactivity could be accounted for by the fchars/alpha.gif" BORDER=0>-pinene in the oil.Keywords: Anemopsis californica, Yerba mansa, steam distillation, SPME, SFE, antimicrobial, elemicin,methyl eugenol
