HS-SPME/GC-GC/MS ANALYSIS OF VOLATILE CONSTITUENTS OF LEONURUS L.

Öz

Objective: The Leonurus genus is one of the 50 essential herbs used in Chinese medicine. This study investigated the volatile components of four Leonurus species collected from different regions of Türkiye and compared their compositions. Material and Method: Four species of the genus Leonurus were collected from different localities. The essential oils were obtained from aerial parts using microdistillation and analyzed by GC-GC/MS. HS-SPME was also applied for volatile profiling. Result and Discussion: The results demonstrated species-specific differences in chemical composition. However, significant amounts of α-pinene were detected in the essential oils of samples from four species. The findings provide the first contribution to the volatile constituents of Leonurus species from Türkiye.

LEONURUS L.’NİN UÇUCU BİLEŞENLERİNİN HS-SPME/GC-GC/MS ANALİZİ

Öz

Amaç: Leonurus cinsi, Çin tıbbında kullanılan 50 temel bitkiden biridir. Bu çalışmada, Türkiye'nin farklı bölgelerinden toplanan dört Leonurus türünün uçucu bileşenleri incelenmiş ve bileşimleri karşılaştırılmıştır. Gereç ve Yöntem: Leonurus cinsine ait dört tür farklı bölgelerden toplanmıştır. Uçucu yağlar, mikrodistilasyon yöntemiyle toprak üstü kısımlarından elde edilmiş ve GC-GC/MS ile analiz edilmiştir. Uçucu profillemesi için HS-SPME de uygulanmıştır. Sonuç ve Tartışma: Sonuçlar, türlere özgü kimyasal bileşim farklılıkları olduğunu göstermiştir. Bununla birlikte, dört türe ait örneklerin uçucu yağlarında önemli miktarda α-pinen tespit edilmiştir. Bulgular, Türkiye'deki Leonurus türlerinin uçucu bileşenlerine dair ilk katkıyı sağlamaktadır.
