Lemongrass (Cymbopogon citratus) essential oil (EO) is a major source of bioactive compounds (BC) with anticancer activity such as ?-citral, limonene, geraniol, geranyl acetate, and ?-caryophyllene. Comparative studies about cytokinin effects on BC profiles in lemongrass are missing. Here, we evaluated four cytokinins (2iP, tZ, BAP, KIN) two different osmotic media, MS-N (3% sucrose, 3 g L?1 Ge...

One of the most effective micronutrients on the quantity and quality of medicinal herbs is zinc (Zn). The present study aimed to assess the impact of the foliar application of various Zn sources (0.2% w/v) including Zn chelated by amino acid (ZnAAC), Zn-sulfate and Zn-EDTA on qualitative and quantitative features of Lemon verbena (Lippia citriodora L.). In two harvests, the field experiment was...

The cascade catalysis of old yellow enzyme, alcohol dehydrogenase and glucose has become a promising approach for one pot, two-step reduction (E/Z)-citral to (S)-citronellol, serving as chiral with rose fragrance. During the multi-enzymatic catalysis, enzyme is responsible conjugated C=C introduction center, requiring high activity (S)-enantioselectiviy. Herein, improve from Providencia stuarti...

Citronellol is a kind of unsaturated alcohol with rose-like smell and its (S)-enantiomer serves as an important intermediate for organic synthesis (-)-cis-rose oxide. Chemical methods are commonly used the citronellol (S)-enantiomer, which suffers from severe reaction conditions poor selectivity. Here, first one-pot double reduction (E/Z)-citral to (S)-citronellol was achieved in multi-enzymati...

An improved method of sample preparation was used in a microplate assay to evaluate the bactericidal activity levels of 96 essential oils and 23 oil compounds against Campylobacter jejuni, Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica obtained from food and clinical sources. Bactericidal activity (BA50) was defined as the percentage of the sample in the assay mixture...
