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.

摘要

目的

天然植物产物被认为是治疗利什曼病的新型有效化合物的来源。在这项研究中,研究了北塞浦路斯生长的 (OD)、 (OM)、 (SF) 和 (LN) 植物的精油对 的活性。

方法

获得了 株(MHOM/TR/2012/CBCL-LT)。在 96 孔平底板中加入 100 μL 的 RPMI-1640,将 100 μg/mL 的精油加入每一行的第一孔,并进行连续 2 倍稀释。将 悬液吸入所有孔中,并孵育。使用血细胞计数器计数 悬液。

结果

OD 精油在最低抑制剂高度(MIC)=0.2 μg/mL 时有效杀死所有 原虫,在最低浓度时具有高活性。SF 和 LN 油的 MIC=1.56 μg/mL 和 LD=0.78 μg/mL。在最低浓度下,SF 被观察到破坏 原虫形态,而 LN 在浓度<0.2 μg/mL 时没有任何作用。OM 精油的 MIC=3.13 μg/mL 和 LD=1.56 μg/mL。

结论

所有测试的精油均抑制了 的 原虫。OD 精油表现出最高的抗利什曼活性。
