Abstract

Aqueous extracts from eleven species of Korean medicinal plants were screened for antiviral activity against transmissble gastroenteritis virus (TGEV) and porcine epidemic diarrhae virus (PEDV). Seven of eleven plant extracts were found to have cytotoxicity for ST cells at the concentration of 1mg/ml, and ten extracts except Ephedra sinica were found to have non-cytotoxicity for Vero cells at the same concentration, Extracts of Zanthoxylum piperium, Cudrina tricuspidata, Clerodendron trichomum, Sophora flavescens, effectively inhibited TGEV, respectively. There were the antiviral activity against TGEV in the extracts of Glesdistsia sinensis, Euonymus alatus, Ficus carica, Solanum nigrum, Ephedra sinica, Xanthium strumarium, Acanthopanax seeliflorus in spite of their cytotoxicities. Nine extracts except Xanthium strumarium and Acanthopanax seeliflorus were found to have the antiviral activitity against PEDV. Extracts of Zanthoxylum piperium, Sophora flavescens was shown to have antiviral activities against both TGEV and PEDV.

11종의 약리식물의 수용성 추출물에서 세포독성능과 TGEV와 PEDV에 대한 항바이러스 효능을 분석하였다. 이들 추출물은 바이러스의 숙주세포로 사용되는 ST세포와 Vero세포에 대해 다른 세포독성능을 나타내었는데, 오가피 추출물은 TGEV에 대한 숙주세포주인 ST 세포에 대해 75.81 %의 세포독성을 나타내었으며, 화살나무, 무화과나무, 까마종이, 마황, 창이자 추출물은 20-50% 사이의 세포독성을 나타내었다. 그러나 마황 추출물(35.66%) 이외의 10종의 추출물은 PEDV에 대한 숙주세포주인 Vero 세포에 대해 세포독성능을 나타내지 않았다. 세포독성이 낮은 식물추출물에서 초피나무, 구지뽕나무, 누리장나무, 고삼 추출물이 TGEV에 대하여 효과적인 항바이러스능을 나타내었으며, PEDV에 대하여는 초피나무, 조각자나무, 고삼, 까마종이, 마황 추출물에서 효과적인 항바이러스능을 나타내었다. 이중에서 고삼과 초피나무 추출물은 TGEV와 PEDV에 대해서 효과적인 항바이러스능을 나타내었다.
