Chemical profile, antioxidant and antimicrobial activity of Christ. Distributed in Bulgaria.

Christ. (Bosnian pine), a Tertiary relict and Balkan sub-endemic, has not been comprehensively studied for its essential oil (EO) profile and bioactivity of its different plant parts. This study aimed to determine the EO yield, composition and antimicrobial activity from different parts of at three different populations (mountains) in Bulgaria.

Introduction: Centranthus kellereri is a Bulgarian endemic plant species, found only in two locations in the world: The Balkans Mountains (Stara Planina), above the town of Vratsa, and The Pirin Mountains, above the town of Bansko, Bulgaria. Being endemic and endangered species precluded any significant research on it. The hypothesis of this study was that the populations of C.

Phytochemical Investigation and Reproductive Capacity of the Bulgarian Endemic Plant Species Boiss. (Lamiaceae).

Boiss (Lamiaceae) is a Bulgarian endemic species. Overall, the essential oil (EO) composition of was different from that of the other species reported in the literature. The main EO constituents of were ()-caryophyllene, germacrene D, and caryophyllene oxide.
