Abstract :
Palmyra palm extractives are one of the wood
chemical components that can have a negative or positive
effect on the utilization of palmyra palm stems. Analysis
of the content of extractive compounds can be carried out
by pyrolysis GCMS analysis. Samples in the form of fine
powder of palmyra stems were used in the extraction
process, using: A) cold-water extraction, B) hot-water
extraction, and C) ethanol-benzene extraction. The
results of the GCMS analysis showed that there were 35
cold-water soluble extractives (Method A), 15 hot-water-
soluble extractives (Method B), and 30 ethanol-benzene
soluble extractives components (Method C). In method B,
the toxic compounds found were Phenol (4.06%) and
Methane, tetranitro- (CAS) Tetranitromethane (1.24%),
while in method A, the toxic compounds were Phenol
(6.21%); Methane, tetranitro- (CAS) Tetranitromethane
(3.19%); Guanosine (CAS) Guo (1.80%); 2-propenyl
decanoate (2.46%) and Lactaropallidin (2.01%). The non-
bioactive compounds, which are lignin derivative,
detected in those three types of extractives, were Phenol,
2-methoxy- (CAS) Guaiacol; and 2,6-dimethoxy- (CAS)
2,6-Dimethoxyphenol. Beside these two compounds, there
were also lignin derivative compounds such as Phenol
compounds, 3,4,5-trimethoxy- (CAS) Antiarol; Phenol,
2,6-dimethoxy-4-(2-propenyl)- (CAS) 4-Allyl-2,6-
dimethoxyphenol; Benzaldehyde, 4-hydroxy-3,5-
dimethoxy- (CAS) Syringaldehyde; Phenol (CAS) Izal;
Phenol, 4-(3-hydroxy-1-propenyl)-2-methoxy- (CAS)
Coniferyl alcohol; and Phenol 2-methyl-5-(1-
methylethyl)- Carvacrol. Each types of extractive from
palmyra stem contained specific organic compounds.
Therefore, in order to produce extractive-free palm
stems, multilevel extractions were used, and to remove a
certain compound, it should be extracted with an
appropriate solvent.
