PENENTUAN KONDISI OPTIMUM KROMATOGRAFI CAIR KINERJA TINGGI UNTUK PEMISAHAN ASAM LEMAK HIDROKSAMIK BERBASIS MINYAK INTI BUAH KETAPANG
Sintesis Asam Lemak Hidroksamik (ALH) telah dilakukan dengan mereaksikan minyak inti buah ketapang dan hidroksilamina secara enzimatis menggunakan lipase terimobilisasi (Lipozyme TL IM). ALH yang didapatkan masih berupa campuran asam-asam lemak penyusun trigliserida minyak inti buah ketapang. Tujuan dari penelitian ini untuk mengetahui kondisi optimum pemisahan campuran ALH menjadi komponen tunggalnya serta persentase komposisinya menggunakan Kromatografi Cair Kinerja Tinggi (KCKT). Kolom, detektor, dan panjang gelombang yang digunakan saat analisis masing-masing adalah kolom fase terbalik (reverse phase) SunFire C18 5 µm 4,6 x 150 mm, detektor Ultra Violet (UV), dan panjang gelombang 213 nm.
