Chlorsulfuron (chemical name : 2-Chloro-N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-aminocarbonyl-benzenesulfonamide) is a herbicidally active ingredient which shows effect against susceptible weeds already at such low rates like 5-20g active ingredient per hectare. In the here reported trials metabolism in several sensitive cultivated plants and weeds have been analysed using ^{14}C-labelled active ingredient. The uptake of chlorsulfuron by leaves or the root system is good in all plants species, and translocation takes place either symplasmatically or apoplasmatically. Metabolism takes place in all investigated plant species by development of hydrophile suhstances in roots and shoots. Decomposition of chlorsulfuron in roots and shoots of tolerant species (Triticum aestivum and Hordeum vulgare) to polare substances takes place quantitatively faster and quicker than in susceptible species (Beta vulgaris and Matricaria chamomilla).

To search for bioactive compounds from plant resources, 80% methanol extracts of 46 species of weeds were screened for their activities of antimicrobial, antioxidative, antiblebing, antitumor and herbicidal. Among extracts tested, some showed activities at the concentration of $50\;to\;100\;{\mu}g/ml$. Phryma leptostachya var. asiatica, Aster ageratoides, Centipeda minima, Cirsium pendulum, Lythrum anceps showed antibacterial activity. Penthorum chinense, Lindernia procumbens, Aster ageratoides, Dianthus superbus var. longicalycinus showed antiblebing activity. Phyma leptostachya var. asiatica, Juncus effusus var. decipiens, Lindernia procumbens, Aster ageratoides, Dianthus superbus var. longicalycinus, Viscum album var. coloratum showed antitumor activity. Juncus effusus var. decipiens, Hypericum ascyron, Juncus papillosus, Inula britannicar var. chinensis, Scirpus wichurae, Hypericum laxum showed antioxidant activity. 다양한 잡초로부터 유용 생리활성물질을 탐색하고자 46종 잡초의 methanol 추출액을 대상으로 $50{\sim}100\;{\mu}g/ml$ 농도로 실험한 결과, 항균 활성에 있어서는 파리풀, 까실쑥부쟁이, 중머리대가리, 큰엉겅퀴, 부처꽃 등이 antobleb 활성에 있어서는 낙지다리, 밭뚝외풀, 까실쑥부쟁이, 술패랭이꽃 등이 항암활성에 있어서는 파리풀, 골풀, 밭뚝외풀, 까실쑥부쟁이, 술패랭이꽃, 겨우살이 등이 항산화활성에 있어서는 골풀, 물레나물, 청비녀골풀, 금불초, 방울고랭이, 좀고추나물 등이 비교적 강한 활성을 나타내었다.
