CHARACTERIZATION OF MORPHOLOGICAL AND BIOLOGICAL ACTIVITY OF EXTRACTS ANDROGRAPHIS PANICULATA

Abstract

Andrographis paniculata is one of many species of herbs in the family Acanthaceae that are commonly used in tropical countries. A. paniculata grows wild in South and Southeast Asian countries including India, Sri Lanka. For traditional Vietnamese medicine, the plant is used to treat diseases such as diarrhea, eczema, dysentery, chickenpox, fever, common cold, pneumonia. In this study, the anatomical structure of roots, stems, and leaves of the radial plant was described by the method of microscopy. The antibacterial activity of the plant extract solution was evaluated by measuring the diameter of the antibacterial ring. The chemical composition was determined by reactive colorimetric method. The results showed that the specimen was made and described the microscopic anatomical structure of the roots, stems and leaves of A. paniculata. The ethanol extract of the plant inhibited three strains of bacteria P. aeruginosa, E. coli and S. Aureus at the lowest concentration of 50 µg/mL. In the plant extract, there were components such as polyphenols, alkaloids, saponins and cumin.
