Structures and Allelopathic Effects of Nuphar Alkaloids: Nupharolutine and 6,6'-dihydroxythiobinupharidine
Chemistry and Biochemistry
Mathematics and Natural Sciences
Two of the major Nuphar alkaloids, nupharolutine and 6,6′-dihydroxythiobinupharidine, were isolated from the aquatic perennial herb Nuphar lutea (L.) Sibth. & Sm., yellow water lily. In a lettuce seedling bioassay of the two pure compounds, the former was inactive and the latter was highly inhibitory of radicle elongation at concentrations greater than 2 ppm. Structures and stereochemistry of the two compounds were confirmed by DEPT,1H-1H COSY,1H-13C COSY, and1H-1H NOESY experiments.
