Abstract

The essential oils from leaves, stems, flowers and rhizomes of Etlingera elatior, an aromatic plant that are widely used in traditional medicine and as a flavour in local dishes were extracted. The essential oils were extracted using the hydrodistillation method and analysed by GC-MS. The percentage yield of volatile constituents of the leaves, stems, flowers and rhizomes were 0.0735%, 0.0029%, 0.0334% and 0.0021%, respectively. The leaf essential oil contained ß–pinene (19.7%), caryophyllene (15.36%) and (E)-ß-farnesene (27.90%) as major compounds whereas the stem essential oil were largely dominated by 1,1-dodecanediol diacetate (34.26%) and (E)-5-dodecane (26.99%). The essential oils of the flowers and rhizomes contained the major compounds 1,1- dodecanediol diacetate (24.38% and 40.37% respectively) and cyclododecane (47.28% and 34.45% respectively).

Minyak pati daripada daun, batang, bunga dan rizom Etlingera elatior, tumbuhan beraroma yang digunakan secara meluas dalam perubatan tradisional dan sebagai perasa dalam masakan tempatan diekstrak. Minyak pati tersebut diekstrak menggunakan kaedah penyulingan hidro dan dianalisa menggunakan GC-MS. Peratusan minyak yang diekstrak daripada daun, batang, bunga dan rizom adalah masing-masing 0.0735%, 0.0029%, 0.0334% dan 0.0021%. Minyak pati daripada daun mengandungi ß–pinena (19.7%), karyofilena (15.36%) dan (E)-ß-farnesena (27.90%) sebagai sebatian utama manakala minyak pati daripada batang didominasi sebatian 1,1-dodekanadiol diasetat (34.26%) dan (E)-5-dodekana (26.99%). Minyak pati darpada bunga dan rizom mengandungi sebatian utama 1,1- dodekanadiol diasetat (masing-masing 24.38% dan 40.37%) dan siklododekana (masing-masing 47.28% dan 34.45%).
