Abstract

|
Growing barley leaves with 2050 cm length were analyzed for chemical constituents including moisture, crude fiber, protein, fat, ash, free sugars, free amino acids, chlorophylls, vitamin C and minerals. During the growth of barley leaves, moisture content decreased, while crude fiber gradually increased. Protein, fat and ash contents of barley leaves remained relatively unchanged. Chlorophyll content increased to a maximum value at the leaf length of 20 cm, and then declined. Minerals of barley leaves were abundant in the following order of K$gt;Ca$gt;P$gt;Na$gt;Mg. Vitamin C content, showing the similar trend to chlorophyll, was the highest at the leaf length of 20 cm. Major free sugars present in growing barley leaves were identified as glucose, fructose and sucrose. All the free sugars reached their maximum values at 20 cm and they were reduced thereafter. Total amount of free amino acids varied from 803 mg% at the Barley stage of l0 cm to 1038 mg% at the later stage of 50 cm. Changes in content for each amino acid were variable to some extent.
