Compounds &lt;strong&gt;2-3b&lt;/strong&gt; were reported to exhibit antibacterial activity and may be partly responsible for the reported antimicrobial activity of the &lt;em&gt;C. rotundata&lt;/em&gt; extract.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">620</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Judy D.V.
