Abstract

Alnus japonica is indigenous to korea and usually grows in wet lowlands and damp regions in the mountains. Oregonin, is known as a representative compound of the diarylheptanoid mainly found in Alnus species and has been reported to have anti-inflammatory and antioxidant effects. In this experiment, we conducted a study on the presence of orogonin in the native Alnus japonica from the Baekdudaegan mountain range in Korea. We collected a total of 30 samples from Chuncheon, Yangyang, and Jeongseon and conducted experiments. In the HPLC analysis, we confirmed that oregonin was detected in all samples. After the quantitative analysis, samples with the highest content from each region were selected and LC-MS/MS experiments were performed. As a result, the same molecular weight as oregonin, 477.2 m/z, was confirmed in all samples.
