Five varieties of napiergrasses (Pennisetum purpureum) were fractionated botanically into leaf blade, leaf sheath, stem and head. Chemical composition of each of whole napiergrass and their botanical fractions were determined. Correlation, linear and multiple regressions between botanical fractions and nutritive value of varieties of napiergrass were also estimated. All botanical fractions diff...

This study was conducted in Alzzazah area which lies approximately 25 km East of El-Dmazein city, the capital of the Blue Nile State, Sudan. This study was carried out at the end of the autumn 2015. The aim of the study was to evaluate the impacts of continuous grazing on the rangeland of the study area. To determine this effect, two range sites were selected to represent the rangeland in the s...

The objectives of this research were to determine the variation of chemical composition across botanical fractions of cornstover, and to use Fourier Transform Near-infrared (FT-NIR) techniques to qualitatively classify separated cornstover fractions, and develop calibration model for the quantitative analysis of chemical compositions of cornstover. Large variations of biomass chemical compositi...

Seven Finnish honeys of different botanical origins were evaluated by 62 untrained panelists by using CATA method with 12 main attribute categories. Samples were also analyzed with SPMEGC-O by using 3 trained assessors and posterior intensity method to correlate sensory characteristics of honey with volatile compositions. Current presentation will cover the different chemometric techniques used...

The objective of this study was to evaluate total antioxidant capacity (TAC), total phenolic content (TPH), and the identification of anthocyanidin and polyphenolic compounds in 13 colored potatoes collected from the Andean region of Bolivia, and understand how the chemical composition correlated with the botanical classification and molecular characterization of genes, ans (anthocyanidin synth...

In the Molise region (Italy), some autochthonous populations are still bred and, between them, some wild horses named 'Pentro horses.' The breeding area is a natural pasture. It is 2200 ha extended including a broad plane surrounded by wooden hills. The aim of this research was to determine the nutritional characteristics of this area over a 2-year period to improve the management of the herd a...

Molecular systematic botany is expanding its role in forensic science. DNA based techniques have been used in criminal cases to place a suspect at the crime scene, as well as to identify strains of marijuana (1,2). These studies have used DNA obtained from individual plant specimens of a known species and have not had to overcome problems associated with DNA mixtures of unkown plant composition...

Volatile compounds in honey samples of different botanical origins were investigated. Solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC/MS) revealed a total of 86 compounds in the headspace of 4 types of honey – multifloral, heather, buckwheat and lime-honeydew. The chemical composition of the headspace was very diverse, owing to the presence of compounds from diff...
