Moreover, this is the first study on EO composition of endemicM. rotundifoliumBoiss. and chemical variabilities of the EOs of otherMarrubiumtaxa collected from Turkey.en10.1080/10412905.2020.1804001info:eu-repo/semantics/closedAccessGC-MSlamiaceaegermacrene Dbeta-CaryophyllenebicyclogermacreneMarrubium rotundifoliumArticle326485493WOS:0005666709000012-s2.0-85090226882Q2Q3
