Abstract
Nyamplung (Calophyllum inophylllum) is one of the mangrove plants which containsfour classes of compounds, such as: triterpenoids, xanthones, flavonoids and coumarins. This study focused on the levels of flavonoid compounds and the effect of differences in amplitude on total flavonoid levels. Flavonoids were extracted using ethanol by UAE at various amplitudes of 20, 40 and 60. Identification phytochemicals was carried out by color reaction tests (shinoda, NaOH, and H2SO4 test) and TLC, while total flavonoid content was obtained by UV-Vis spectrophotometry with quercetin as standard. Data analysis will be carried out by using linear regression method. The color reaction test (shinoda, NaOH and H2SO4) showed positive results for the three types of extracts which were indicated by a change in color to red in the shinoda and H2SO4 test, yellow in the NaOH test. Rf in TLC test respectively: 0.804, 0.782, and 0.760 and the quercetin standard: 0.804,.The total flavonoid levels were obtained respectively: 1.166 mg QE/gram, 1.290 mg QE/gram, 1.590 mg QE/gram. These results show that the amplitude of 60% (which is the highest variation) also has the highest total flavonoid content. Key Words : Nyamplung, UAE, Total Flavonoid, Amplitudo Ekstraction
