Abstract

Phytochemicals are naturally formed in plant of corn. Many kinds of flavonoids are the most important plant pigment. Purple corn is extracted with polar and nonpolar solvent and analyzed for flavonoids and antioxidants. The extract residue of purple corn is compared on extraction with various solvent groups. In the designed experiments, conditions of extraction depend on solvent, solvent ratio and evaporation temperature. The residue quantity of purple corn is respectively from extraction with three kinds of solvent such as acetone, chloroform: methanol (3:1) and pentane: hexane (1:1). All residue extract are eluted and with mobile phase and analyzed with diode array detector by HPLC. Anthocyanin, ?-carotene and total tannin of purple corn were taken analysis an average (mean ± SD) in 100 g sample and shown as 198.42 ± 0.33 mg, 175.82 ± 0.17 mg and 273.75 ± 0.33 mg respectively. The efficiency of solvent extraction depends on the polarity of the substances. The extract by acetone can take the highest residue and mixture solvent take a high residue. The different polarities of solvent can make the difference of residue product in the extraction. Improving and development on the changes are useful for the best of raw material and products.

Highlights

A classification is provided the groups in order to understand the general standard of purple corn. 2.1.1 Preparation of Purple Corn Powder and Drying Fresh purple corn is sliced in size [1,2] mm and crushed to a fine shred
The samples are pulverized to a fine powder and stored in seal container for further analysis and the other process. 2.1.2 Determination of Moisture Content Fresh purple corn is sliced in size [1,2] mm and dry with the vacuum oven
2.2.5 Determination of Amylose Content in Purple Corn The samples are dissolved with urea and dimethylsulfoxide (UDMSO) in a water bath at high temperature until changed in gel formulation

Summary

Introduction

Purple pigments of purple corn have the properties of free radicals and reduce symptoms of cancer tumor types. They enhance the strengthen of body, increase an immunity antibodies and the red blood cells. The phytonutrients are natural compounds or substances found in certain plants which is believed to be beneficial to human health and help prevent various diseases. This class of phytonutrients includes pigments such as carotenoids (beta-carotene, lutein), flavonoids or phenolics, alkaloids, nitrogen-containing compounds and organosulfur compounds (indoles, glucosinolates). The type of polarity, dipole moment, and hydrogen bonding of solvent is able to specify the dissolve
