Johnst. (syn. &lt;em&gt;Rimelia austrocetrata&lt;/em&gt; Elix and J. Johnst.) which belongs to a large genus of lichenized fungi, &lt;em&gt;Parmotrema Massalongo&lt;/em&gt; under family Parmeliaceae was investigated for its chemical constituents. &lt;strong&gt;Methods:&lt;/strong&gt; The compounds were isolated by silica gel chromatography and their chemical structures were elucidated by NMR spectroscopy. Results: Chemical investigation of the dichloromethane extract of &lt;em&gt;Parmotrema austrocetratum&lt;/em&gt; Elix and J. Johnst. has led to the isolation of zeorin &lt;strong&gt;(1)&lt;/strong&gt; and atranorin &lt;strong&gt;(2).&lt;/strong&gt; &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;P. austrocetratum&lt;/em&gt; shares similar chemical characteristic with other Parmotrema species which afforded atranorin. This work highlights the first reported isolation of &lt;strong&gt;1&lt;/strong&gt; from &lt;em&gt;P. austrocetratum&lt;/em&gt; and the genus Parmotrema.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s27</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Consolacion Y.
