SINTESIS NATRIUM PENTAGAMAVUNONAT DAN UJI STABILITASNYA MENGGUNAKAN SPEKTROFOTOMETER UV-Visible
ABSTRACT: A research
on the synthesis
of sodium pentagamavunonat (Na-PGV-0)
and its stability test
using UV-Visible spectrophotometer were
carried out. The
synthesis of Na-PGV-0
carried out by
reacting PGV-0 in
tetrahydrofuran solvent refluxed
with sodium ethoxide in
mol comparison (1:2)
for two hours.
Structure elucidation by
spectroscopic methods using UV-Visible,
IR, 1H-NMR, 13C-NMR and
stability test in
water using UV-Visible
spectrophotometer. The reaction
yields 107,21 %
(% w/w) products.
A products was soluble in water and
methanol. Structure elucidation results
indicated that the formed compound where
the OH phenolic
of pentagamavunon-0 was
replaced by sodium
ions. Stability test shows
that decreasing of
sodium pentagamavunonat to
70,7867 % in 600
minutes storage.
