Abstract

To explore the Korea native plants to substitute for St. John's wort, which produce hypericin that use commercially for the treatment of mild to moderate depression, hypericin contents of Hypericum erectum and H. ascyron collected in two mountain of Korea were examined. From TLC and TLC-densitometer analysis of hypericin contents and biosynthetic pattern, hypericin was detected in flower and leaf of H. erectum, but not in all organs of H. ascyron. The hypericin content of H. erectum grown 200 m high hill in Mt. Byoung-pung was higher than that of Mt. Ji-ri 500 m and 1300 m high hill. When the seasonal variation of hypericin contents in H. erectum leaf collected from two regions was investigated, leaf collected from both regions on July was higher than other seasons.

2003년 6, 8월에 지리산과 전남 담양군의 병풍산에서 자생하는 고추나물과 물레나물을 채집하여 TLC 분석을 하고, TLC-densitometry를 이용해 정량한 결과, 물레나물에서는 hypericin이 확인되지 않은 반면, 고추나물의 꽃봉오리와 잎에서는 다량의 hyepricin이 확인되었다. 그리고 지리산에 자생하는 고추나물보다 병풍산 고추나물의 hypericin함량이 더 높게 나타났고, 고도가 낮을수록 hypericin 함량이 높은 것으로 나타났다. 채집 시기별로 비교했을 때, 병풍산은 6월보다 7월에서 hypericin함량이 높게 나타났고, 지리산에서는 7월에 가장 진하게 보였다. St. John's wort와 고추나물을 비교하였을 때, 2.22 $mg/{\ell}$ hypericin을 함유한 St. John's wort 보다 3.2 $mg/{\ell}$의 함량을 보이는 병풍산 고추나물에서 hypericin함량이 더 높은 것으로 확인되었다.
