Ekstraksi Hidrotermal Senyawa Paradol dari Jahe

Abstract

Ginger contains a variety of active constituents. The active constituents of ginger are very diverse and varied.
The diversity of the active constituents of ginger can depend on the type of ginger, ginger planting location
and circumstances of ginger (fresh or dried). One of the ginger active constituents that reported having some
pharmacological activities is paradol. Several extraction methods have been carried out to obtain the active
compound of ginger, paradol. Hydrothermal extraction has gaining many interests from the researches due to
the unique properties of subcritical water used in the hydrothermal process. This research objective was to
study the effect of extraction parameter process i.e. reaction temperature (1300C and 1400C) and time (10-40
minutes). Hydrothermal extraction process carried out at a fix pressure of 2 bar. The research showed that the
hydrothermal extraction process carried out at a fix pressure of 2 bar, a temperature of 1300C and extraction
time of 20 minutes was able to produce extracts with paradol content of 19%. The hydrothermal extraction
process carried out at a temperature of 1300C, a pressure of 2 bar for 10 minutes can produce extracts
containing paradol of 16%, while the hydrothermal extraction process carried out at a temperature of 1300C,
a pressure of 2 bar for 30 minutes is only able to produce extracts containing paradol of 6%.
