The Effect of Different Plant Parts and Solvent Extraction on Chemical Content and Quercetin Levels of Ketapang (Terminalia cattapa L.)

Ketapang has flavonoid content that is quercetin. The appropriate solvent can attract the active compound of quercetin on ketapang. The selection of solvents adjusts different levels of polarity with the aim of obtaining the best solvent. Differences in plant parts can also affect the amount of quercetin levels. This study aims to determine the difference between plant parts and extraction solvents to the quercetin levels of ketapang plants. Simplisia fruit and leaves ketapang made by winding. Maceration is carried out on each fruit and leaves of ketapang using 3 different solvents namely n-hexane, ethyl acetate, and ethanol 90%. The viscous extract obtained was analyzed for yield value and the phytochemical screening test was do qualitatively. Quercetin level measured by UV-Vis Spectrophotometry at a maximum wavelength of 375.6 nm. The absorbance value obtained is entered into the standard quercetin curve equation with the equation y=0.0885x+0.0037. The results of the yield value of ketapang leaf and fruit extracts with each different type of solvent resulted in different yield values, as well as the results of phytochemical screening and percent quercetin levels obtained. Analysis of the results concluded that differences in solvents and plant parts affected the yield value, chemical content and percent content of quercetin in ketapang plants.
