Nuphar japonica is one of three species in the genus Nuphar that is dispersed in the same geographical location of the Saijo Basin, an area in the Hiroshima Prefecture of Japan.[4]
Cytology
editThe chromosome count is 2n = 34.[5]
Natural hybrids
editNuphar × saijoensis (Shimoda) Padgett is a hybrid between N. japonica and N. pumila.[citation needed]
Phytochemistry
editN. 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,[6] C, D, E and F.[7]
