<p>In&nbsp;this&nbsp;study,&nbsp;the&nbsp;essential&nbsp;oil&nbsp;of&nbsp;Psephellus&nbsp;pyrrhoblepharus&nbsp;(Boiss.)&nbsp;Wagenitz&nbsp;was&nbsp;obtained&nbsp;by&nbsp;hydrodistillation&nbsp;using&nbsp;a&nbsp;Clevenger-type&nbsp;apparatus.&nbsp;The&nbsp;oil&nbsp;was&nbsp;analysed&nbsp;by&nbsp;GC&nbsp;and&nbsp;GC/MS&nbsp;system.&nbsp;The&nbsp;components&nbsp;were&nbsp;separated&nbsp;as&nbsp;for&nbsp;adherence&nbsp;to&nbsp;the&nbsp;column&nbsp;and&nbsp;evaluated&nbsp;as&nbsp;for&nbsp;relative&nbsp;rate.&nbsp;Mass&nbsp;spectra&nbsp;of&nbsp;each&nbsp;component&nbsp;were&nbsp;taken.&nbsp;GC&nbsp;and&nbsp;GC/MS&nbsp;analyses&nbsp;of&nbsp;the&nbsp;essential&nbsp;oil&nbsp;from&nbsp;P.&nbsp;pyrrhoblepharus&nbsp;determined&nbsp;the&nbsp;identification&nbsp;of&nbsp;59&nbsp;components&nbsp;representing&nbsp;84%&nbsp;of&nbsp;the&nbsp;oil.&nbsp;With&nbsp;this&nbsp;analysis,&nbsp;the&nbsp;major&nbsp;component&nbsp;was&nbsp;found&nbsp;as&nbsp;hexadecanoic&nbsp;acid&nbsp;(17.1%).&nbsp;Subsequent&nbsp;to&nbsp;this&nbsp;component,&nbsp;other&nbsp;major&nbsp;components&nbsp;were&nbsp;spatulenol&nbsp;(10.3%),&nbsp;caryophyllene&nbsp;oxide&nbsp;(9.6%)&nbsp;and&nbsp;heptacosane&nbsp;(5.2%).&nbsp;In&nbsp;addition&nbsp;to&nbsp;this,&nbsp;fatty&nbsp;acid&nbsp;methyl&nbsp;esters&nbsp;(FAMEs)&nbsp;from&nbsp;P.&nbsp;pyhhoblepharus&nbsp;were&nbsp;prepared&nbsp;for&nbsp;analysis&nbsp;of&nbsp;fatty&nbsp;acids.&nbsp;By&nbsp;this&nbsp;test&nbsp;the&nbsp;amount&nbsp;of&nbsp;saturated&nbsp;fatty&nbsp;acids&nbsp;(SFA)&nbsp;were&nbsp;31.37%&nbsp;with&nbsp;major&nbsp;fatty&nbsp;acid&nbsp;palmitic&nbsp;acid&nbsp;(12.86%).&nbsp;Also,&nbsp;the&nbsp;antioxidant&nbsp;assays&nbsp;DPPH,&nbsp;ABTS,&nbsp;ORAC,&nbsp;CUPRAC&nbsp;and&nbsp;reducing&nbsp;power&nbsp;assay&nbsp;were&nbsp;carried&nbsp;on&nbsp;methanol:water,&nbsp;n-hexane,&nbsp;chloroform&nbsp;and&nbsp;ethyl&nbsp;acetate&nbsp;extracts&nbsp;of&nbsp;P.&nbsp;pyrrhoblepharus.&nbsp;With&nbsp;the&nbsp;assays,&nbsp;ethyl&nbsp;acetate&nbsp;extract&nbsp;of&nbsp;P.&nbsp;pyrrhoblepharus&nbsp;was&nbsp;found&nbsp;as&nbsp;the&nbsp;most&nbsp;antioxidant&nbsp;extract.&nbsp;These&nbsp;data&nbsp;show&nbsp;that&nbsp;the&nbsp;plant&nbsp;is&nbsp;valuable&nbsp;for&nbsp;further&nbsp;studies.</p>
