@article{._T S_Jennie_Apriyantono_Yasni_2010, title={Spectroscopic Characteristics of Antibacterial Component of Atung (Parinarium glaberrimum Hassk) Seeds}, volume={15}, url={https://journal.ipb.ac.id/index.php/jtip/article/view/521}, abstractNote={<div>Relative purity assay on antibacterial components (isolates) of “atung” seeds using HPLC system (linier gradient of water-methanol, detection on UV at 280/254 nm) showed that the isolate-9 had the highest purity (94%), followed by isolate-6 (69%), isolate-7 (66%), and isolate-12 (66%) respectively; while the other isolates only had 50% of purity. The UV-Visible spectrophotometer analysis on the isolate-9, showed that the λ<sub>max</sub> (in methanol) were at 213 and 269 nm. From IR spectrum of the isolate, no more information can be obtained except the presence of C-H stretching. Furthermore, the MS spectrum showed that the fragment ion series of 44 (100%), 57, 69, 83, 97, 115, maybe predicted as aliphatic amine compounds.<br /> <em><strong>Key word</strong> : Relative purity, methanol, C-H Stretching, fragment ion series, aliphatic amine compounds.</em></div&gt;}, number={1}, journal={Jurnal Teknologi dan Industri Pangan}, author={.Murhadi and T SSoewarno and JennieBetty S.L and Apriyantono, Anton and Yasni, Sedarnawati}, year={2010}, month={May}, pages={1} }
