    ISOLASI SENYAWA METABOLIT SEKUNDER DAN UJI TOKSISITAS EKSTRAK ETIL ASETAT DARI DAUN Rhizophora mucronata
    (2021-01) Mizanty, Denissabianda; Yuharmen, Yuharmen
    Rhizophora mucronata is a type of mangrove that has diverse secondary metabolites. The purpose of this study was to isolate secondary metabolites and to determine toxicity test by BSLT method. Ethyl acetate extract produces a pure substance in the form of white crystals with the melting point of 218-220 oC. The isolated compound was coded as RmEF1. UV spectrum of RmEF1 indicated absorption at λmax 311 nm. The FT-IR absorption spectrum showed absorption peaks at 1037 (C-O), 1384 (C-H) methyl,1472 (C-H) methylen, 1606 (C=C), 1707 (C=O), and 2934 (C-H aliphatic). The result of toxicity test by BSLT (Brine Shrimps Lethality Test) method on that crude extract was non-toxic.
