Lignan Content in Commonly Consumed Korean Vegetables; 우리나라 다소비 채소류에 함유된 리그난 함

초록

Lignans are phytoestrogens found in various plants and exhibit diverse biological activities, including antioxidant, anti-inflammatory, and anticancer effects. This study aimed to analyze the content of six major lignans-lariciresinol, matairesinol, medioresinol, pinoresinol, secoisolariciresinol, and syringaresinol in 91 vegetables, including 39 leafy vegetables, 15 fruit vegetables, 15 root and tuber vegetables, 11 mushrooms, and 11 miscellaneous vegetables, using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The total lignan content in wild chive and avocado were relatively high at 1,430.485 μg/100 g and 1,412.684 μg/100 g, respectively. Additionally, Med was detected only in blanched chard among all the samples, with a content of 0.419 μg/100 g. To ensure the reliability of the research results, analytical method validation and quality control were performed according to the guidelines of the Association of Official Agricultural Chemists. These findings provide reliable data on lignans in vegetables and will contribute to the development of a lignan database for agricultural and food resources. © 2024 The Korean Society of Food Science and Nutrition.
