Phytochemistry | 1970

7-Epideoxynupharidine from nuphar luteum subsp. variegatum☆☆☆

Chun Fook Wong; Robert T. LaLonde

Abstract 7-Epideoxynupharidine has been isolated from Nuphar luteum subsp. variegatum .


Phytochemistry | 1972

Sulfur containing alkaloids from Nuphar luteum

Robert T. LaLonde; Chun Fook Wong

Abstract Alkaloids neothiobinupharidine and thionuphlutine-A were isolated from rhizomes of Nuphar luteum obtained from Poland. These two alkaloids were not detected in the two North American Nuphar examined. However a bishemiaminal form of thionuphlutine-A has been isolated from North American Nuphar . Thionuphlutine-A is identical with the previously reported thiobinupharidine.


Phytochemistry | 1970

The structure of 3-epinuphamine, a new alkaloid from nuphar luteum subsp. variegatum☆

Chun Fook Wong; Robert T. LaLonde

Abstract The structure of a new alkaloid from N. luteum subsp. variegatum is shown to be that of 3-epinuphamine, I (R  CH 2 OH, R′  H).
