Estimation Some of Metal Ions and Biological Constituents of Local Rheum Ribes (Rhubarb) of Kurdistan Region - IRAQ

Abstract

It is an attempt to determine the levels of (1) minerals by using ICP spectrophotometer; (2) the fatty acids, by using (HBLC) chromatography technique; (3) vitamin C by using Redox titration method. Levels were found to be as bellow:

1. Metal ions levels were found to be gradually decreased from monovalent to divalent ions, whereas the levels of biological constituents were varied and resulted in :

Ash(fibers) = % 6.702 , Water %86, Linolenic acid 39.08 µg/ml , ?- Linoleic acid 31.32 µg/ml,  Arachidic  acid  12.13 µg/ml, Erucic acid 4.1 µg/ml and Vitamin C 4.83 µg/ml.

2. As shown the levels of fatty acids were decreased with increasing unsaturated.

Keywords: metal ions, fatty acids, and ascorbic acid in Rheum Ribes (Rhubarb).
