Nuphar × saijoensis (Shimoda) Padgett is a hybrid between N. japonica and N. pumila.

N. japonica contains the alkaloids nupharidin, 1-desoxynupharidin, nupharamine, methyl and ethyl esters of nupharamine. The fruits also contains the alkaloids (0.06%) nupharine, beta-nupharidin, desoxynupharidin. In the rhizomes are found the steroid sitosterol, alkaloids acids, higher fatty acids (palmitic, oleic acid) and the ellagitanins nupharin A, B,[3] C, D, E and F.[4]
