ISOLASI DAN IDENTIFIKASI SENYAWA FLAVONOID DARI DAUN TUMBUHAN KEREHAU (Callicarpa longifolia Lam.)
Abstrak: The flavonoid had
been isolated from ethyl acetate extract of Kerehau leaf (Callicarpa longifolia
Lam.). Extraction was done by maceration and fraction method. Isolation of pure
compound was done by chromatographic flash coloumn. The resulted of isolated
flavonoid was yellow greeness powder and 174-178°C melting point. Based on data
IR can be conclude that isolated compound is flavonol group. Effect of toxicity
from isolate identified with presentage of prawn larva (BSLT method) and
counted by probit analysis (LC 50 ). The results of this test showed that the
the isolate was very toxic with LC 50 value of 26,8824 ppm.
