In pursuit of effective, safe and affordable antileishmanial drugs, the current study was designed to explore Corchorus capsularis L. leaf extract (CCEx) as an effective leishmanicidal substitute against Leishmania donovani. The leaf extract displays potent antileishmanial activity against L. donovani promastigotes with an IC value of 79.00 ± 0.3 μg/ml. CCEx also significantly induces intracellular reactive oxygen species (ROS) with a concomitant decrease in the level of non-protein thiols in virulent parasites. Additionally, CCEx treatment induces substantial morphological alterations in parasites. Moreover, reagent-based phytochemical analysis of the extract revealed the presence of various phytochemical constituents. Further study is underway to identify the bioactive component(s) or fraction(s) of CCEx through bioassay-guided fractionation.

An unconventional separation method of α-Terpineol from its isomer 1,8-Cineole via in situ-association formation of deep eutectic solvent and machine learning.

α-Terpineol and 1,8-cineole are two important compounds in essential oils. This study developed an efficient method to recover α-terpineol from model oil (MO) based on association extraction by in situ formations of deep eutectic solvent (DES) between α-terpineol and some quaternary ammonium salts (QASs) by hydrogen-bond (HB) interaction. Such interaction could be broken almost completely by the introduction of water, due to the stronger HB interaction between water and QASs, which could release α-terpineol by liquid-liquid separation and save the organic solvents consumption.
