Antileishmanial Activities of Carvacrol Nanoencapsulate in Biopolymeric Nanoparticles

Chemistry &Biodiversity, EarlyView.
The study obtained biopolymeric nanoparticles containing carvacrol (NPCar) and evaluated their anti‐leishmanial activity. NPCar obtained presented physicochemical characteristics due to its ideal nanometric size and zeta potential, and low polydispersity index.

Immobilised porphyrins in monoterpene photooxidations [PDF]

Journal of Catalysis, 2008
Porphyrins were covalently linked to modified Merrifield polymers by chlorosulphonation activation of the porphyrin nucleus. These supported porphyrins were used as photosensitizers to promote singlet oxygen oxidation of monoterpenes with an efficiency that depends on porphyrin structure and the spacer used to link it to the polymer structure.

Unveiling the Chemical Profile of Teucrium chamaedrys subsp. gracile (Batt.) Rech.F. dried Aerial Parts From Algeria

Chemistry &Biodiversity, EarlyView.
ABSTRACT In this paper, the first phytochemical analysis on Teucrium chamaedrys subsp. gracile was reported. The dried aerial parts collected in Algeria were studied, and the analysis was conducted using different techniques: gas chromatography/mass spectrometry (GC/MS) for the fatty acid content, headspace solid‐phase microextraction‐GC‐MS for the ...
