- Abstract: To clarify the functions of Coix-seed Reactive Derivatives(CRD), we analyzed 13 kinds of phenolic compounds and coixol(an alkaloid) in CRD powder by using Liquid Chromatography/Mass Spectrometry(LC-MS).The following are the results: p -Coumaric acid 275.0 (μg/g), p -Hydroxybenzaldehyde 50.2 (μg/g), Caffeic acid 36.9 (μg/g), Protocatechuic acid 31.9 (μg/g), Ferulic acid 27.1 (μg/g), Quercetin 16.2 (μg/g), Syringaldehyde 12.1 (μg/g), Chlorogenic acid 11.3 (μg/g), Naringenin 11.1 (μg/g), Vanillin 9.2 (μg/g), trans -Coniferylaldehyde 9.1 (μg/g), Tricin 0.7 (μg/g), Luteolin 0.5 (μg/g) and Coixol(6-Methoxy-2-benzoxazolinone) 5.5 (μg/g). CRD is composed of many substances other than these phenoic compounds. Therefore, further studies are needed to understand the various clinical features associated with CRD intake.
