Prior efforts to incorporate bark or bark extracts into composites have met with only limited success because of poor performance relative to existing products and/or economic barriers stemming from high levels of processing. We are currently investigating applications for southern yellow pine (SYP) bark that require intermediate levels of processing, one being the use of carefully ground and c...

Citrus flavonoid concentration in different tissues of citrus from different species around the world were compared together with citrus related traditional Chinese Medicine (TCM) ingredients. The citrus species with high flavonoid content like Citrus aurantium and the flavonoid-enriched tissues such as peel and young fruit are frequently utilized in TCM recipes for their gastric protective, an...

Aim: We determined the chemical composition and larvicidal activity of essential oil distilled from Citrus sinensis (L.) Osbeck husks pattern major constituent. Materials methods: For this, we distill by hydrodistillation, identify components gas chromatography coupled with mass spectrometry (GC-MS), test against Aedes aegypti calculate lethal concentration at 50% (LC50) Reed-Muench method conf...

Citrus Huanglongbing (HLB) is the most devastating disease of citrus. HLB has spread to most of the citrus growing areas in the world and causes significantly decline in both citrus production and citrus industry economic output. HLB is caused by three species of fastidious, phloem-resided alpha proteo bacteria: ‘Candidatus Liberibacter asiaticus’ (Las), ‘Candidatus Liberibacter americanus’(Lam...

Export of Citrus spp. fruits may require risk mitigation measures if grown in areas with established tephritid fruit fly (Diptera: Tephritidae) populations capable of infesting the fruits. The host status of Citrus spp. fruits is unclear for two tephritid fruit fly species whose geographic ranges have expanded in recent years: melon fly, Bactrocera cucurbitae (Cocquillett), and Bactrocera latif...

Comprehensive two-dimensional liquid chromatography (LC×LC) using the Agilent 1290 Infi nity 2D-LC Solution with DAD and MS detection is applied for the analysis of citrus oils. The developed method uses normal phase liquid chromatography in the fi rst dimension and reversed-phase liquid chromatography in the second dimension. This combination provides good orthogonality and is valuable for pro...

The bark of black spruce was thermo-mechanically refined and used to manufacture binderless bark-based fiberboard with various pressing temperatures, times, and panel structures in order to utilize an abundant bark resource for a better value-added application. The test results indicated that it is technically feasible to manufacture binderless fiberboard with refined black spruce bark through ...
