This article presents the results of a gas chromatography-mass spectrometry (GC-MS) study of the chemical composition of Cupressus sempervirens L. (Mediterranean cypress) and Thuja occidentalis L. (northern white-cedar) essential oils, as well as their activity against four strains of pathogenic fungi infecting crops. Our observations revealed high concentrations of monoterpenes, sesquiterpenes, mono-teppernic and sesquitepernic alcohols, ethers and esters, and flavonoids in the essential oil samples of both plants. Notably, the growth of pathogens was significantly inhibited by α-pinene (44.73% for C. sempervirens and 27.74% for T. occidentalis ) and α-terpineol (4.04% and 5.14%, respectively) found at high levels. The selective effect exerted by all the compounds on the strains of the phytopathogenic fungi tested was established. C. sempervirens L. essential oil displayed the highest antifungal activity against fusarial wilt ( Fusarium graminearum FG-30) and snow mold ( Microdochium nivale ) pathogens.
本文采用气相色谱-质谱联用技术研究了地中海柏树(Cupressus sempervirens L.)和北方白柏树(Thuja occidentalis L.)精油的化学成分及其对4种作物病原菌的活性。我们的观察发现，两种植物的精油样品中都含有高浓度的单萜、倍半萜、单萜和倍半萜醇、醚和酯以及类黄酮。α-蒎烯和α-松油醇对病原菌的生长有显著抑制作用，α-蒎烯的抑制率分别为44.73%和27.74%，α-松油醇的抑制率分别为4.04%和5.14%。所有化合物对所测植物病原真菌菌株均有选择性作用。对枯萎病(Fusarium graminearum FG-30)和雪霉菌(Microdochium nivale)的抑菌活性最高。

Amyloid fibrils are ordered aggregates that from a wide variety of soluble proteins and peptides. Amyloid fibrils take part into more than 20 human diseases, including Alzheimer’s, Parkinson, Huntington and HIV infection. The association of certain proteins with the fibril structure formation characterizes the pathological manifestation of amyloid diseases. Clarification of the physicochemical parameters of the amyloid fibril formation is critical to our understanding and subsequent treatment of amyloid diseases. There are several comprehensive studies of self-assembly mechanisms of functional and pathogenic polypeptides. peptide
