| Abstrak Sri Devi. 2020. Analysis of Flavonoid levels in Pandan Wangi leaf extract (Pandanus amaryllifolius Roxb). Thesis, Chemistry education study Program. Department of Mathematics and Natural sciences, Faculty of teacher training and education, Tadulako University. Supervisor: Sitti Aminah Pandan Wangi (Pandanus amarylifolius Roxb.), is a species of pandanus that has fragrant leaves. Pandan wangi is one of the ingredients that can be utilized as a traditional medicine. The purpose of this research is to know the total levels of flavonoids contained in the Pandan Wangi leaf extract with the UV-Vis spectrophotometry method. Analysis of flavonoids levels the total extract of Pandan wangi leaves is determined based on the Absorbancy value measured at a wavelength of 432 nm using kuersetin comparator. The results show that the total flavonoids levels of the pandan wangi leaves is 268.958 mg/100g. Keywords: ethanol extract, pandan leaf, total flavonoid content, UV-Vis spectrophotometry. |
