The use of cyanidin (3, 3 1 4 1 5, 7 – pentahydroxyflavylium chloride) extracted from a tropical plant Hibiscus sabradiffa L. as a chelating reagent for simultaneous spectrophotometric determinations of ions of Pb, Hg, Cd, As and Ni in mixed aqueous solution is reported. The purified extract of the dried calyces of the Roselle plant was characterized and the results compared with literature val...

This paper focuses on hybrid and twisted Indian mallow/roselle cellulosic fiber yarn mat reinforced polyester composites effects of their wood sawdust filler. The composite materials were fabricated usingcompression moldingtechnique. There four different combinations samples used, while the hybrids six. An evaluation mechanical properties for single double layer cases was done with without fill...

There is currently an increased consumption of vegetables within the local urban community. However, contamination of these vegetables with heavy metals poses a potential health hazard. Consequently, the potential contamination problem due to the effect of levels of some heavy metals (Fe, Mg, Zn, Mn, Cu and Cr) in soils and vegetables irrigated with drainage urban grey waste water were investig...

Fruit bars are prepared by combining different ingredients which wholesome and nutrient rich. The current study was designed to develop roselle–fig (different proportions) fruit further investigate their physicochemical characteristics antioxidant potential. Moreover, the were scrutinized for microbial sensory assess appropriateness of during storage (up 90 days). It observed that there gradual...

In Thailand, the roselle seeds have a few utilizations other than for planting propagation. Consequently, this study aimed to evaluate nutritional and mineral profile of in Northeast region Thailand. The obtained results proved that were found be good source carbohydrates (41.48 ± 0.31 %), protein (30.40 0.09 fat (19.70 0.04 %). Additionally, indicated rich fiber (40.61 0.26 %) had high energy ...
