HPLC 분석에 의한 해동피와 개두릅의 성분함량 비교

To evaluate the leaf shoots and stem barks of Kalopanax pictus (Araliaceae) as an edible vegetable and a traditional medicinal drug, respectively, the compounds of syringin, liriodendrin, astragalin, quercetin, and kalopanaxsaponins were quantitatively measured by HPLC analysis. The leaf shoot exhibited low contents of syringin, liriodendrin and kalopanaxsaponins but a high chlorogenic acid content, whereas the grown leaves contained very high amounts of kalopananxsaponins. In contrast, the stem bark had very high amounts of syringin and liriodendrin and relatively low kalopanaxsaponins. In particular, the kalopanaxsaponin contents were rapidly increased with monthly variation until October but decreased from September. It was also observed that the leaf shoot contained chlorogenic acid by 30.73 mg/g and the barks showed the concentration of liriodendrin by 20.75 mg/g. These results indicate that high contents of syringin and liriodendrin in the stem bark and high contents of chlorogenic acid in the leaf shoot support scientific bases on the traditional uses of K. pictus as a medicinal drug and a functional food, respectively.
