Chemical compositions of the essential oils from Iranian populations of Rhabdosciadium aucheri Boiss. (Apiaceae).

Chemical compositions of the essential oils from Iranian populations of Rhabdosciadium aucheri Boiss. (Apiaceae). Nat Prod Res. 2021 Jan 13;:1-6 Authors: Kazemeini F, Asri Y, Mostafavi G, Kalvandi R, Mehregan I Abstract Rhabdosciadium aucheri has a limited distribution in west, center, and south of Iran. The aim of the present study was to assess essential oil content and variability in seven natural populations employing GC-FID and GC-MS analyses. Aerial parts of the specimens were collected at the full flowering stage. Overall, 27 chemical components were determined in the populations. The essential oil yields varied from 0.05% to 0.12%. The most abundant compounds were germacrene D (10.7-51.7%), β-sesquiphellandrene (0.8-54.6%), β-elemene (0.3-39.5%), juniper camphor (3.5-20.8%), limonene (0.4-19.6%) and α-pinene (0.4-4.5%) among the populations. Due to some variations observed in the essential oil components between populations, four different chemotypes were recognized including Chemotype I (germacrene D/β-sesquiphellandrene/juniper camphor), Chemotype II (β-elemene/germacrene D), Chemotype III (germacrene D/β-sesquiphellandrene) and Chemotype IV (β-elemene/germacrene D). The variations that occurred in chemical compositions among populations could be valuable in the pharmaceutical industries and conservation strategies.
