INFLUENCE OF REGION FOR SOME CHEMICAL COMPOSITION OF THE LOTUS LEAF

Abstract

Lotus leaves contain a number of chemical components that have good effects on human health, however their content varies in different regions. This article presents the results of a study to determine content some chemical components of lotus leaves in three provinces are Phu Tho (PT), Hung Yen (HY) and Dong Thap (DT). Specifically, the highest total polyphenol content of DT reached 10.05 g/100g; PT reached 6.16 g/100g and HY reached 5.75 g/100g. The corresponding flavonoid content are 7.43 g/100g; 4.01 g/100g and 3.95 g/100g. The corresponding total alkaloid content are 0.26 g/100g; 0.23 g/100g and 0.17 g/100g. The highest total mineral content of PT reaches 9.60 g/100g; HY reaches 7.00 g/100g and DT reaches 6.00 g/100g. The corresponding total organic acid content are 1.23g/100g; 1.22 g/100g and 1.13 g/100g
