Abstract

Java turmeric (Curcuma xanthoriza) is one of the native plants from Indonesia. Java turmeric is known as a medicinal plant with a high content of volatile oils. In this study, we investigated the chemical profile of java turmeric essential oil obtained by hydrodistillation associated with different harvesting times of the rhizome (7, 9, and 11 months). The constituent of the essential oil was determined by using gas chromatography-mass spectrometer. About 19, 20 and 34 compounds were identified in 7, 9, and 11-month old java turmeric. Fifteen compounds were found in all samples namely β-elemene, zingiberene, γ-elemene, β-farnesene, α-curcumene, benzofuran, α-cedrene, epicurzerenone, ar-curcumene, germacrone, aromadendrene, α–longipene, trans-caryophilene, curcuphenol, and xanthorrhizol. This study showed the level of all compound detected in 7, 9, and 11 months old of java turmeric is different.

Abstract

Profil sidik jari kromatografi lapis tipis (KLT) dapat dimanfaatkan untuk kendali mutu bahan baku maupun produk tumbuhan obat. Penelitian ini bertujuan mengembangkan metode analisis sidik jari rimpang temu mangga (Curcuma mangga) untuk kendali mutunya. Rimpang kering temu mangga diekstraksi menggunakan metanol dan dianalisis sidik jari KLT. Kloroform:etil asetat (8.5:1.5) merupakan fase gerak optimum yang memisahkan 11 pita dari rimpang temu mangga dengan keterpisahan yang baik dan memiliki pita khas biru tua (Rf 0.36). Demetoksikurkumin terdeteksi pada rimpang temu mangga dengan warna jingga kecoklatan pada UV 366 nm (Rf 0.48) setelah diderivatisasi dengan pereaksi asam sulfat 10%. Pengujian spesifitas terhadap rimpang lain dalam satu genus, rimpang temu mangga menunjukan pola yang berbeda. Validasi metode analisis sidik jari KLT memenuhi kriteria keberterimaan, sehingga metode ini dapat digunakan untuk kendali mutu rimpang temu mangga.
