Three Tetracyclic Triterpenoic Acids from Dysoxylum densiflorum and Their Antibacterial Activities
Abstract:
This paper reports the chemical isolation and antibacterial properties of terpenoid components of Dysoxylum densiflorum. Three new tetracyclic triterpenoic acids, densiflorinic acids A-C (1-3), were isolated from the acetone extract of the plant's leaves. The structures of the three compounds were determined mainly by extensive analysis of 1-D and 2-D NMR spectroscopic data. On antibacterial evaluation, the highest activity was shown by compound 1 against Bacillus subtilis with an IC50 of 26.5 μM.

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
