PERBANDINGAN ISOLASI MINYAK ATSIRI BIJI PALA (Myristica fragrans Houtt) CARA HIDRODISTILASI MICROWAVE DAN KONVENSIONAL SERTA UJI AKTIVITAS ANTIBAKTERI DAN ANTIOKSIDAN

Abstract

Essential oil of nutmeg (Myristica fragrans Houtt) has been successfully obtained by distillation using conventional and microwave hydrodistillation methods. The essential oil produced by microwave method is more advantageous in yield of oil and components of resulted compounds. The yield of extracted essential oil using microwave method is about 7,07% for 60 minutes higher than that of conventional method which is about 4,30% for 4 hours. Based on the result of GC-MS analysis, microwave hydrodistillation components obtained 55 compounds more than conventional hydrodistillation as many as 43 compounds in essential oil. The results of antibacterial and antioxidant activity showed that essential oil could inhibit Bacillus subtilis of bacteria and had weak antioxidant activity than of ascorbic acid againts DPPH radical that is >1000 ug/mL.
