استخلاص زيت بذور ثمار العرديب وتحديد خواصه الفيزيائية والكيميائية

Abstract

The aim of this research was the determination the chemical and physical properties of the seed oil of aradib (Tamarindusindica) using (GC/MS) .The oil was extracted using soxhlet device with normal hexane as solvent . The properties of seeds and the extracted oil were determined.thefinal results of the seed components were as follows : oil content 2.17% moisture 8.26% ash 3.25% protein 24.76% fiber 19.14% and carbohydrates 42.42% . For the physiochemical properties of the oil were as follows : refractive index 1.46 density 0.91(g/ml) acid value 2.063 )Mg KOH/g oil(peroxide value 0.3 )Mg KOH/g oil(non saponification value 3.5 )Mg KOH/g oil(and the saponification value 224.44)Mg KOH/g oil.(And for the results of the oil analysis using the (GC/MS) device it showed the presence of saturated fatty acids 40.81% and un saturated 59.19% . The study concluded that the seed oil of aradib fruits cannot be used edible oil but it can be used in medical therapeutic, cosmetics and industries due to its acid content (linolenic acid 32.54% oleic 23.12%) at high rates .
