Leucobryum glaucum (Leucobryaceae)'un Uçucu Yağının Kimyasal Bileşimi ve Antimikrobiyal Özellikleri

Bu çalışmada, Leucobryum glaucum (Hedw.) Angstr.'nin uçucu yağının detaylı çalışması gaz kromatografisi/ alev iyonlaştırma dedektörü (GC/FID) ve gaz kromatografisi/ kütle spektrometresi ile değerlendirildi hem de uçucu yağ ve çözücü ekstraktlarının (n-hekzan ve metanol) antimikrobiyal aktivitesi incelendi. Sonuçlara göre, thujopsadien (% 35.5) ve β-curcumen (% 25.4) başlıca bileşenler olmak üzere toplamda 47 bileşik belirlendi. Çalışmanın ikinci kısmında ise uçucu yağ ve çözücü ekstraktlarının antimiktobiyal aktivitesi 9 mikroorganizmaya karşı minimum-inhibisyon-konsantrasyonu (MİK) değerleri 61-4235 µg / mL aralığında test edildi.

Antimicrobial Properties and Chemical Composition of the Essential Oil of Leucobryum glaucum (Leucobryaceae)

In this study, a detailed study of the essential oil from Leucobryum glaucum (Hedw.) Angstr. was evaluated by gas chromatography/flame ionization detector (GC/FID) and gas chromatography/mass spectrometry (GC/MS) methods as well as screened for antibacterial activities of the essential oil and solvent extracts (n-hexane and methanol). According to the results, a total of 47 compounds were detected, among which thujopsadiene (35.5%) and β-curcumene (25.4%) were the main components. In the second part of this study, the essential oil and solvent extracts were tested for its antimicrobial activity against 9 microorganisms with minimal-inhibitory-concentration (MIC) values in the range 61-4235 µg / mL.
