Phytochemical researches and antimicrobial activity of Clinopodium nubigenum Kunth (Kuntze) raw extracts

The essential oil of the species Clinopodium nubigenum Kunth (Kuntze) was analyzed. Among the 70 compounds identified, the majority are oxygenated monoterpenoids. The essential oil resulted effective in vitro against Candida albicans. From the aqueous MeOH extract of the aerial parts of the plant two nonvolatile compounds, named schizonepetoside A and schizonepedoside C, have been isolated. They are rare glycosyl terpenoids, which were previously isolated from only one plant, but never found before in the genus Clinopodiu
