Abstract

Lilium lancifolium is native to Northeast Asia and its bulbs have been used for medicinal treatment. Moreover, Japan has been using L. lancifolium bulbs more actively as food ingredients than Korea. Therefore, this study was to investigate the characteristics of Korean L. lancifolium bulbs, with respect to food component and functionality. As a result of proximate composition analysis, L. lancifolium bulbs have an abundant carbohydrate content. HPLC analysis indicated p-coumaric acid and ferulic acid contents of Korean L. lancifolium extract were 1.14 ± 0.01, 1.46 ± 0.00 mg/g, but only p-coumaric acid was less detected in Japanese extract. Also, Korean L. lancifolium bulbs extract exhibited significant antioxidant effects, as evaluated with antioxidant activity and compound, than Japanese extract. Furthermore, Korean L. lancifolium bulbs extract significantly inhibited pro-inflammatory protein expressions through MyD88 dependent pathway. Therefore, these results suggested Korean L. lancifolium bulbs have the potential to being functional food ingredients. PRACTICAL APPLICATIONS: Lilium lancifolium is a perennial plant belonging to the Liliaceae family. The storage organ of L. lancifolium is surrounded by several fleshy nodes at the base of the stem, called the bulb, which has been used as food or medicine to treat pneumonia and bronchitis. L. lancifolium is widely found in countries of Northeast Asia, such as Korea, Japan, and China, and its bulbs have been studied for presence of bioactive compounds that have important functional activities. The bioactive compounds in the L. lancifolium bulbs may vary from region to region. In this study, the difference observed in the contents of different bioactive compounds and the efficacy of anti-inflammatory effects of L. lancifolium bulbs from different regions were consistent in this regard. As a comparative study of food materials by region, these L. lancifolium bulbs have the potential to be used as a food material for preventing inflammatory diseases.

Keywords: Lilium lancifolium bulb; RAW 264.7 cells; anti-inflammation; antioxidant.
