60종(種)의 약용식물과 식용작물을 대상으로 항종양활성등의 생리활성을 조사함으로서 약용식물과 식용작물의 유용적인 측면의 확인뿐만 아니라 나아가서 새로운 생리활성물질 탐색의 가능성을 검토하기 위해서 실험하였으며 결과는 다음과 같다. 약용식물 및 식용작물에 대한 80% EtOH 추출물을 이용하여 항종양효과를 보면 PKC법에서는 명아주(73.4%) 및 antibleb형성억제력검정에서는 검정콩이, PLC법에서는 검정콩(91.9%), MTT법에서 50%의 억제력을 나타내는 농도$(IC_{50})$가 검정콩과 쑥의 경우 각각 $4.7{mu}g/ml$을 보였다.
This study was conducted to screen antitumoral activity by in vitro bioassay method using 60 Korean medicinal and food plants extracted by 80% EtOH. Antitumor activity test was applied by the PKC(protein kinase C) and antibleb formation, PLC (Phospholipase C), and colorimetric tetrazolium assay (MTT assay) methods. Chenopodjum album and black Glycine max showed high antitumoral activity by 73.5% and 81.0%, respectively, against PKC by bleb-forming assay and PKC enzyme assay on human chronic leukemia K562 cell. Black Glycine max also showed 91.2% antitumoral activity in the PLC method and the lowest $IC_{50}$ $value(4.7{mu}g/ml)$ by MTT method against P-338 cell line. In the effect of the concentration treatment on antitumoral test, the more concentration indicated the more activity value.
