Abstract:
Alpinia malaccensis plants was one of essential oil source which has antimicrobial
activity. Isolation of essential oil from Alpinia malaccensis was carried out with
traditional hydrodistillation method and microwave method. Optimal conditions in the
traditional method was 6 hours, while the optimal conditions in the microwave method
were 100 oC, 600 W, and 90 minutes. Isolation of the essential oil from Alpinia
malaccensis with traditional method produces higher yield (0.009%) compared to
microwave method (0.002%). Compounds in the essential oil of Alpinia malaccensis
stem identified by GC-MS. The main component of essential oil rod Alpinia
malaccensis obtained by using hydrodistillation and microwave-assisted
hydrodistillation is methyl cinnamic as much as 98.24% and 96.97% respectively.
Essential oils rod hydrodistillation of Alpinia malaccensis from traditional
hydrodistillation method and hydrodistillation microwave method was active as an
antimicrobial agent.
