چکیده
Due to the economic interests in vetiver, Chrysopogon zizanioides (L.) Roberty, molecular and chemical studies are essential to generate information for its sustainable exploitation. The aim of this study was to undertake a molecular and chemical characterization of vetiver accessions of the active germplasm bank of the Universidade Federal de Sergipe. The molecular characteristics of the accessions were studied using amplified fragment length polymorphism markers, with a total of 14 primer combinations that generated 442 loci, allowing us to observe that these accessions have similar genomes. The vetiver accessions were divided into three distinct groups, where accession UFS-VET005 was the most differentiated and accession UFS-VET004 had the lowest essential oil content (0.70%). The content of the chemical constituents of the essential oils was observed to vary, with a predominance of khusimol, which ranged from 18.97 to 25.02%. It was possible to divide the vetiver accessions into two groups based on chemical composition, and these groups do not correlate with the molecular grouping. Therefore, it is necessary to perform molecular and chemical analyses to characterize vetiver accessions.

Vetiver [Chrysopogon zizanioides (L.) Roberty syn. Vetiveria zizanioides (L.) Nash] commonly known as khas-khas, khas, khus-khus or khus grass belongs to the family Poaceae. The roots of this grass on steam distillation yield an essential oil mainly consisting of sesquiterpenes (3-4 %), sesquiterpenols (18-25 %) and sesquiterpenones (7-8 %). Among these, the major economically important active ...

Vetiver grass was harvested at 4, 6 and 8-week old re-growth. The chemical composition and quantitative analyses of anti-nutritional components were determined. The result showed that dry matter and fiber content increased with age while crude protein, mineral content and anti-nutritional components reduced with age. It was concluded that age of re-growth significantly affect the nutrient and a...

Vetiver grass was harvested at 4, 6 and 8-week regrowth and were ensiled with cassava peels at ratio 60:40 and 100% without cassava peels. The quality and chemical composition of the silages were assessed. The silages along with fresh unensiled re-growths of vetiver grass were fed to WAD goats in a cafeteria method to determine the coefficient of preference of the diets. Results showed that ens...
