SATU SENYAWA ASAM ORGANIK YANG DIISOLASI DARI DAUN GEDI (Abelmoschus manihot L. Medik) ASAL SULAWESI UTARA
This research was aimed
to isolate and identify the structure of secondary metabolities from gedi leaf.
In order
to achieve this
research aim, an extraction of the gedi leaf tissue with methanol solvent had
been carried out.
These extract then was
partitioned in several organic solvents such as n-hexane, chloroform and ethyl
acetate.
Further, the resulted
partition was fractionation and purifying undergoes an appropriate method like
liquid and
vacuum pressure
chromatography and also determining the melting points. To determine the
chemical structure
of the isolate, a
compilation of several spectroscopic methods, such as infrared (IR), 1H and 13
C nuclear
magnetic resonance (NMR),
techniques (HMQC, HMBC, and COSY). Results of this research shown that one
major
constituent was isolated from the leaf of gedi: heptadecanoid acid.[HOW TO DOWNLOAD OR READ MORE]
