Abstract
Validation and quantitative analysis of cadmium, chromium, copper, nickel, and lead in snake fruit by Inductively Coupled Plasma-Atomic Emission Spectroscopy
Highlights
Fruits are parts of human diet sources
The fruit may be contaminated with heavy toxic metals such as cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and lead (Pb)
The results showed that inductively coupled plasma-atomic emission spectroscopy (ICP-AES) was linear over the concentration ranges of 0.025–1.0 μg/mL for Cd, Cr, and Ni and 0.050–1.0 μg/mL for Cu and Pb, respectively
Summary
Fruits are parts of human diet sources. Snake fruit (Salacca zalacca), locally in Indonesia known as “salak”, is one of the favourite fruits for Indonesian people. “Pondoh” cultivar which originally grown in Yogyakarta province is the most popular snake fruit cultivar due to its high aroma intensity and sweetness (Supriyadi et al, 2002). Snake fruit contains various nutritional compounds such as fibers, proteins, fats, and carbohydrates and possesses high level of antioxidant (Goristein et al, 2009). Snake fruit positively affected plasma lipid levels in cholesterol fed. Tan et al / Journal of Applied Pharmaceutical Science 8 (02); 2018: 044-048 diarrhoea (Agarwal et al, 1993). Ni may cause gastrointestinal and cardiovascular disorder, liver damage, and carcinogenic effect (ATSDR, 2005). Pb nephrotoxicity is characterized by proximal tubular nephropathy, glomerular sclerosis and interstitial fibrosis (Goyer, 1989; Loghman-Adham, 1997)
