원주산과 옥천산 참옻나무의 부위별 flavonoid 및 urushiol 함량 비교

국문 초록 (Abstract)

참옻나무의 줄기전체, 껍질, 목질부위에 함유되어있는 총 phenol 함량은 원주산이 각각 15.73, 13.29, 13.21, 옥천산이 16.14, 16.63, 14.81 mg gallic acid/g db이었다. 총 flavonoid 함량은 원주산이 32.04, 15.16, 31.05, 옥천산이 45.51, 22.09, 43.48 mg quercetin/g db로 나타났다. Flavonoid 성분 중 fustin이 껍질 부위에서는 성분 합계양의 98%이상, 줄기와 목질에서는 73.0-86.7%를 차지하는 주요성분이었다. Butein은 부위별로 0.31-2.17, fisetin은 0.27-3.32, sulfuretin은 0.15-0.80 mg/g db 함유되어 있었다. 각 부위별 urushiol 함량의 합계는 각각 5.09-6.29, 55.05-56.30, 0.38-0.39 mg/100 g dry base로 껍질에 다량함유 되어 있었다. 껍질에 함유된 urushiol congener들의 분포는 C15:3 (pentadecatrienyl catechol)이 63%, C15:1 (pentadecenyl catechol)이 33-35%, C15:2 (pentadecadienyl catechol)가 2-3% 함유되어 있었다.

다국어 초록 (Multilingual Abstract)

Fustin comprised >98 and 73.0-86.7% of the total flavonoid content in the bark, and the stems and lignum of Rhus verniciflua, respectively. The butein, fisetin, and sulfuretin content varied between 0.31-2.17, 0.27-3.32, and 0.15-0.80 mg/g on a dry weight basis, respectively, in different parts of Rhus verniciflua. The urushiol content was 5.09-6.29, 55.05-56.30, and 0.38-0.39 mg/100 g on a dry weight basis in the stems, bark, and lignum, respectively. This showed that the bark of the tree had the highest urushiol content. C15:3 (pentadecatrienyl catechol), C15:1 (pentadecenyl catechol), and C15:2 (pentadecadienyl catechol) comprised 63, 33-35, and 2-3% of urushiol congeners in the tree bark, respectively.
