AI Article Synopsis

  • The study investigates the anti-leishmanial properties of essential oils obtained from four different plants in Northern Cyprus, focusing on their effectiveness against a specific strain of leishmania.
  • Various concentrations of the essential oils were tested for their ability to kill promastigotes, with OD oil showing the highest effectiveness at a minimum inhibitory concentration (MIC) of 0.2 μg/mL.
  • The results indicate that all tested essential oils have some inhibitory effects on the promastigotes, but OD essential oil was particularly notable for its potent anti-leishmanial activity compared to the others.

Article Abstract

Objective: Natural plant products are considered as a source of novel and effective compounds for the treatment of leishmaniasis. In this study, the activities of essential oils obtained from (OD), (OM), (SF) and (LN) plants in Northern Cyprus were investigated against .

Methods: strain (MHOM/TR/2012/CBCL-LT) was obtained. RPMI-1640 was added to 96-well plates in 100 μL aliquots, 100 μg/mL essential oil was added to the first well of each row and serial 2-fold dilutions were performed. A promastigote suspension was pipetted into all wells, and the plates were incubated. The promastigotes were enumerated using a haemocytometer.

Results: OD essential oil was effective at killing all promastigotes at a minimum inhibitor height (MIC)=0.2 μg/mL and had high activity at the lowest concentrations. Both SF and LN oils had MIC=1.56 μg/mL and LD=0.78 μg/mL. SF was observed to impair promastigote morphology at the lowest concentrations, while LN did not exert any effect at concentrations <0.2 μg/mL. OM essential oil was found to have a MIC=3.13 μg/mL and a LD=1.56 μg/mL.

Conclusion: All tested essential oils inhibited promastigotes of . OD essential oil demonstrated the highest anti-leishmanial activity.

AmaÇ: Bitkilerden elde edilen doğal ürünlerin leishmaniasis tedavisi için yeni ve etkili bileşiklerin üretilmesine öncülük edeceği düşünülmektedir. Çalışmamızda, Kuzey Kıbrıs’ta yetişen (OD), (OM), (SF) ve (LN) bitkilerinden elde edilen uçucu yağların ’ya karşı etkinlikleri araştırılmıştır.

YÖntemler: Çalışmamızda, suşu (MHOM/TR/2012/CBCL-LT) kullanıldı. Düz tabanlı 96’lık plaklarda, tüm kuyucuklara 100 μL RPMI-1640 ve ilk kuyucuklara 100 μg/mL uçucu yağlar eklenerek, seri dilüsyonları yapıldı. Ardından tüm kuyucuklara promastigot süspansiyonundan pipetlendi ve inkübe edildi. Hemositometre yöntemiyle promastigotların sayısı incelendi.

Bulgular: OD yağının minimum inhibitör konsantrasyonu (MİK)=0,2 μg/mL’de tüm promastigotları öldürürken, en düşük konsantrasyonlarda bile etkili olduğu görülmüştür. SF ve LN uçucu yağlarının ikisinde de MİK=1,56 μg/mL, LD=0,78 μg/mL olarak saptanmıştır. SF’nin en düşük konsantrasyonlarının bile promastigot morfolojisini bozduğu görülürken, ’in ise 0,2 μg/mL’den sonraki konsantrasyonlarda etkisini kaybettiği belirlenmiştir. OM uçucu yağının MİK=3,13 μg/mL, LD=1,56 μg/mL olduğu görülmüştür.

SonuÇ: Kullanılan tüm uçucu yağların promastigotlarını inhibe ettiği görülürken, en yüksek anti-leishmanial etkinlik uçucu yağında bulunmuştur.
