Abstract

This final project research is about the use of plants that have potential as herbal medicines with the aim of identifying secondary metabolites in the plant Qust^ Al-Hindi (Saussurea Lappa) by carrying out phytochemical tests including flavonoids, alkaloids, steroids or terpenoids, tannins, and saponins. In addition, it is also expected to be able to determine the levels of flavonoids by UV-Vis characterization and confirm the presence of the same functional group between compounds that are typical of secondary metabolites and compounds contained in these plants using FTIR ATR. The results of this study indicate that the plant contains secondary metabolites in the form of flavonoid compounds, alkaloids, terpenoids, and tannins. The flavonoid content obtained was 223.33 \pm 66.5 mgQE/g, while the results of the FTIR ATR test showed that the extract contained the same functional groups as flavonoids, alkaloids, terpenoids and tannins, namely the O-H, C-H, C=C functional groups. C=O, and C-O contained in the flavonoid structure, alkaloid compounds are known to have a distinctive functional group, namely N-H, for terpenoids to have a distinctive functional group, namely C-H which is CH2 and CH3, there is also CH and there is a C-O group which is a functional group typical of tannin compounds.
