Secondary Ionization Mass Spectrometry-Linked Scanning Analysis for Identification of Aloenin in Foods Containing Aloe arborescens MILLER

概要

論文の詳細を見る
Secondary ionization mass spectrometry (SIMS)-linked scanning analysis was used as a method for identifying a specific Aloe arborescens MILLER (Kidachi-aroe) component, aloenin, in health foods containing Kidachi-aroe. The compound was extracted with methanol and identified in positive mode and constant B/E using SIMS-linked scanning analysis without any further purification such as a chromatography. Kidachi-aroe was detected in the sample using aloenin as an indicator. In the SIMS-linked scanning spectra of health foods containing Kidachi-aroe, peaks were observed of a quasi-molecular ion (m/z 411[M+H]^+) and its daughter ion at m/z 249,indicating the structure of aloenin. Kidachi-aroe was thus detected when present in health foods. The proposed method is easy, rapid and accurate for both characterization and estimation of aloe materials in health foods containing Kidachi-aroe.
