PEMURNIAN CATECHIN DARI GAMBIR KOTO PANJANG, PESISIR SELATAN
N Ferdinal - Jurnal Riset Kimia, 2015 - scholar.archive.org
The research about catechin purification from gambier was purposed to find its solubility
properties in various solvent such as in cold water, hot water, hexane, ethyl acetate, and
methanol. By knowing its solubility properties, the easiest way to purify the catechin could be
gotten which is yielding about 7.33%. Further, the molecular structure has been gotten by
determining its melting point and using spectrophotometric measurements such as UV, IR,
1H NMR, 13C NMR. Based on those measurements, d-cathecin structure with a melting …
