Analysis of Marker Compounds in Lindera erythrocarpa from Diverse Geographical Regions of Korea

초록

Lindera erythrocarpa M., a medicinal plant commonly found in China, Japan, and Korea, is well known for its antioxidant, anti-inflammatory, and potential anti-cancer effects. However, data on the quantification of different marker compounds found in this species across plant parts and geographical regions remain limited. To address this gap in the literature, the marker compounds methyl lucidone (1), methyl linderone (2), and kanakugiol (3) in leaves and stems of L. erythrocarpa collected from five different regions in the Republic of Korea were analyzed using high-performance liquid chromatography (HPLC/UV). Among the three compounds analyzed, kanakugiol (3) was the most abundant and was predominantly found in the stem samples. Overall, stems contained higher concentrations of methyl linderone (2) and kanakugiol (3) than the leaves. These findings highlight the importance of considering regional factors and plant part selection to maximize the yield of bioactive compounds. The results support the potential of L. erythrocarpa as a medicinal source and contribute to the standardization and quality improvement of herbal goods, thereby enhancing consumer protection and product efficacy. © 2024 by the authors.
