Kim, Sunyoung Kim, Dan-Bi Lee, Sanghee Park, Jisu Shin, Dongbin Yoo, Miyoung Profiling of organosulphur compounds using HPLC-PDA and GC/MS system and antioxidant activities in hooker chive (<i>Allium hookeri</i>) <p>This study investigates the comprehensive organosulphur compounds and evaluation of antioxidant activities in <i>Allium hookeri</i>, called hooker chive. The non-volatile and volatile organosulphur compounds were determined by high-performance liquid chromatography-photodiode array detector (HPLC-PDA) and gas chromatography-mass spectrometry (GC-MS), respectively. Among 11 non-volatileorganosulphur compounds, methiin and cycloalliin were major compounds. A total of 42 volatile compounds were identified and allyl methyl sulphides and dimethyl sulphides were primarily volatiles. The total phenols ranged from 19.32 to 71.19 mg gallic acid equivalents (GAE)/g. The antioxidant capacities expressed IC<sub>50</sub> values ranged from 9.59 to 38.54 mg/mL for DPPH radical scavenging activity and from 0.39 to 2.36 for ferric reducing antioxidant power assay. The results were proposed as useful tools for evaluating the nutraceutical of hooker chive.</p> Allium hookeri;organosulphur compound;total phenolic;antioxidant activity 2016-04-07
