Aroma is considered a fundamental component of fruit flavor. Variations in the composition and content volatile organic compounds (VOCs) contribute to noticeable differences aromas. Litchi delicious tropical subtropical fruit, large number germplasm resources with unique aromas have emerged during past 2000 years cultivation. In this review, our aim collect, compare, integrate, summarize availa...

Geranyl diphosphate (GPP), the precursor of most monoterpenes, is synthesized in plastids from dimethylallyl diphosphate and isopentenyl diphosphate by GPP synthases (GPPSs). In heterodimeric GPPSs, a non-catalytic small subunit (GPPS-SSU) interacts with a catalytic large subunit, such as geranylgeranyl diphosphate synthase, and determines its product specificity. Here, snapdragon (Antirrhinum ...

Essential oil of Cymbopogon citratus collected from Brazil and Cuba was tested to a chemical characterization and then was tested on the post-embryonic development of Musca domestica. The chemical composition analysis by GCMS of the oils from Brazil/Cuba allowed the identification of 13 and 12 major constituents respectively; nine of them common to both. In the both oils, the main components we...

Many Gram-negative pathogens have the ability to produce N-acylhomoserine lactones (AHLs) as signal molecules for quorum sensing (QS). This cell-cell communication system allows them to coordinate gene expression and regulate virulence. Strategies to inhibit QS are promising for the control of infectious diseases or antibiotic resistant bacterial pathogens. The aim of the present study was to e...

This study aims to evaluate the benefits of some herbs such as antioxidant, antibacterial, and anti-cancer activities Lemongrass (Cymbopogon citratus), peppermint (Mentha longifolia), wormwood (Artemisia absinthium) essential oils (EOs). The chemical composition was identified using GC-MS technique. total phenolic content antioxidant were monitored by radical scavenging assay (DPPH). Furthermor...

Oils extracted from Cymbopogon citratus, Lantana camara, Artemisia camphorata, and Imperata cylindrica plants were used as potential insecticides against the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae). The phytochemical composition of isolated oils was identified by gas chromatograph-mass spectrometry (GC-MS). Oil contact toxicities evaluated adults S. oryzae. activities ac...
