In this research work, the Dalbergia Lanceolaria L., Myanmar name Thit pagan was selected to qualify and quantify the flavonoids present in it. The stem bark of Thit pagan was collected from Minbu Township, Magway Region, Myanmar. Firstly, the preliminary phytochemical test of this selected plant was carried out which gave positive for glycoside, flavonoid, polyphenol phenolic, sugar, saponin, tannin, terpene, alkaloid, and lipophenol test. Furthermore, the mineral contents of selected sample were measured by EDXRF method. Moreover, the total flavonoids of selected sample were extracted with 95% EtOH. This extract was checked for qualitative test of flavonoids. It responds positive for Ferric Chloride test, Shinoda’s test and Lead Acetate test respectively. In addition, total flavonoid content of Dalbergia Lanceolaria L. was evaluated by the aluminum chloride (AlCl3) method using UV/Visible spectrophotometer (UV-1800, SHIMADZU, UV spectrophotometer) at 510 nm. The total flavonoid content of this selected sample was determined as 41.17 ? 0.11 mg quercetin equivalent (QE) per gram dry weight.
