Penetapan Kadar Tanin Total Ekstrak Buah Nangka Muda (Artocarpus heterophyllus Lamk.) Secara Spektrofotometri Uv-Vis
Empirically, young jackfruit (Artocarpus heterophyllus Lamk.) Can treat diarrhea. Tannins are very complex organic substances and consist of phenolic compounds which are found in many kinds of plants. The purpose of this study was to determine the secondary metabolites found in the ethanol extract of young jackfruit (Artocarpus heterophyllus Lamk). To determine the total tannin content of young jackfruit fruit extract (Artocarpus heterophyllus Lamk). This research was carried out by making the ethanol extract of young jackfruit (Artocapus heterophyllus Lamk.) By maceration method using 96% ethanol solvent. The total tannin content determination test was carried out by the UV-vis spectroscopy method with the concept of the complex reaction of the ciocalteu acid-folin tannin complex read at a wavelength of 745 nm. Determination of total tannin content using tannic acid as the standard standard solution found in young jackfruit (Artocapus heterophyllus Lamk). The results of phytochemical screening of young jackfruit (Artocapus heterophyllus Lamk) have alkaloids, tannins, saponins, flavonoids. The spectroscopy method in testing total tannin levels can be done because it has a good linear regression coefficient value of 0.9981. Results: The tannin content in the ethanol extract sample of young jackfruit fruit was 35.6 ppm.
