Abstract
INDONESIA:
Bawang dayak (Eleutherine palmifolia (L.) Merr.) adalah tumbuhan asli Indonesia yang memiliki potensi untuk dikembangkan menjadi fitofarmaka dan sudah lama digunakan secara empiris oleh masyarakat untuk mengobati beberapa penyakit, salah satunya adalah kanker. Perbedaan lokasi tumbuh diduga dapat menyebabkan perbedaan kandungan senyawa metabolit pada spesies tumbuhan yang sama, sehingga dilakukan metabolite profiling umbi bawang dayak. Sampel bawang dayak dikumpulkan dari enam lokasi yang berbeda yaitu Jawa Timur, Jawa Tengah, Jawa Barat, Kalimantan Timur, Kalimantan Tengah, dan Kalimantan Selatan. Tujuan penelitian ini adalah untuk mengetahui profil metabolit bawang dayak yang berasal dari beberapa daerah yang berbeda di Indonesia.
Ekstraksi sampel dilakukan menggunakan metode Ultrasound Assisted Extraction (UAE) dengan pelarut etanol 96% perbandingan 1:20 [b/v], analisis kandungan senyawa metabolit dilakukan menggunakan UPLC-QTOF-MS/MS dengan fase diam kolom C18 (okta desil silika), fase gerak campuran asam format/air 0,1/99,9 (v/v) dan asam format/asetonitril 0,1/99,9 (v/v). Hasil analisis di interpretasi menggunakan perangkat lunak Masslynx dan dilanjutkan dengan analisis kemometrik menggunakan metode Principle Component Analysis (PCA). Hasil yang diperoleh yaitu terdapat perbedaaan profil metabolit antar keenam daerah, ditemukan senyawa isoliquiritigenin dan resveratrol yang diketahui memiliki aktivitas sebagai antikanker, serta diketahui senyawa mayor pada umbi bawang dayak yang berasal dari enam daerah di Indonesia.
ENGLISH:
that has the potential to be developed into phytopharmaca and has long been used empirically by the community to treat several diseases, one of which is cancer. The difference in growth location is allegedly to cause differences in the content of metabolites in the same plant species, so metabolite profiling of bawang dayak bulbs is carried out . Bawang dayak samples were collected from six different locations, they are East Java, Central Java, West Java, East Kalimantan, Central Kalimantan, and South Kalimantan. The purpose of this study was to determine the profile of bawang dayak metabolites originating from several different regions in Indonesia.
The extraction of samples was conducted using Ultrasound Assisted Extraction (UAE) method with 96% ethanol solvent ratio of 1:20[b/v], the analysis of the metabolite compounds content was conducted out using UPLC-QTOF-MS/MS with stationary phase C18 column (octa decile silica), the mobile phase of the mixture of formic acid/water is 0.1/99.9 (v/v) and formic acid/acetonitrile is 0.1/99.9 (v/v). The results of the analysis were interpreted using Masslynx software and followed by chemometric analysis using the Principle Component Analysis (PCA) method. The results obtained were that there were differences in metabolite profiles among the six regions, it was found that isoliquiritigenin and resveratrol compounds were known to have anticancer activity, as well as known major compounds in bawang dayak bulbs originating from six regions in Indonesia.
