Arthropod pests are among the biggest problems faced in tomato production worldwide. To overcome losses caused by these pests, one of most sustainable and economical strategies is use resistance introgressed from wild species. We aimed to develop BC3F2 genotypes with high levels zingiberene (ZGB) whitefly (Bemisia tabaci biotype B), South American pinworm (Tuta absoluta), two-spotted spider mit...

Background: Propionibacterium acnes is a commensal bacteria that play role in developing acne vulgaris on the skin. Antibacterial activity assay last decades have shown resistant to several antibiotics. Potential zingiber genera such as Z. officinale, montanum, and zerumbet potential antibacterial. Objective: This study aims compare antibacterial of montanum against acnes, active fraction, comp...

The present study aimed to examine the chemical composition and biological activity of essential oils extracted from Euphorbia macrorrhiza collected from Northwest China. The major constituents of the essential oils of aerial parts and roots of E. macrorrhiza are acorenone B (16.72% and 25.80%), (+)-cycloisosativene (14.94% and 12.40%), 3a-hydroxy-5b-androstane (10.62% and 5.52%), copaene (7.37...

Plants of the genus Zingiber (Family Zingiberaceae) are widely used throughout the world as food and medicinal plants. They represent very popular herbal remedies in various traditional healing systems; in particular, rhizome of Zingiber spp. plants has a long history of ethnobotanical uses because of a plethora of curative properties. Antimicrobial activity of rhizome essential oil has been ex...

They represent very popular herbal remedies in various traditional 52 healing systems; in particular, rhizome of Zingiber spp. plants has a long history of ethnobotanical 53 uses because of a plethora of curative properties. Antimicrobial activity of rhizome essential oil ha...

The essential oils are extracted from plant compounds and can present activities antimicrobial and antioxidant properties. The goals of the present study were: (a) to determine the chemical composition of the essential oil of Guarea kunthiana A. Juss using the method of gas chromatography coupled to mass spectrometry (GC-MS); (b) to evaluate the antimicrobial potential of this oil using the bro...

OBJECTIVE The purpose of this study was to assay the antifungal activity of selected essential oils obtained from plants against both fluconazole (FLU)-resistant and FLU-susceptible C. albicans strains isolated from HIV positive patients with oropharyngeal candidiasis (OPC). MATERIALS AND METHODS The essential oils were obtained by hydrodistillation method from Myrtus communis (My. communis),...

The sampling techniques headspace solid-phase microextraction (HS-SPME), petrol ether extraction (PEE) and steam distillation extraction (SDE) were compared for the GC-MS of volatile constituents present in ginger (Zingiber officinale). The effects of different parameters, such as extraction fibers, extraction time, extraction temperature and particle size ranges, on the HSSPME of rhizome of gi...

Ginger (Zingiber officinale Roscoe) rhizomes are mostly used as spice and medicine due to their high aroma intensity medicinal bioactive compounds. However, the volatile compounds of ginger, partly responsible for its properties, can be affected by pretreatment, drying method, extraction processes employed. The objective this study was assess effects pretreatment on yellow ginger variety at nin...

Zingiber officinale Roscoe is an herbal plant native to Asia that can be found in all tropical countries. It used folk medicine, food, and cosmetics. A chemical characterization some agronomic experiments have been carried out on Z. essential oil, showing promising findings for the biological control of fungal pathogens belonging genus Fusarium. The aim this review collect update literature cov...
