Abstract: In order to provide the basic data for production and cultivation of Hibiscus rosa-sinensis Linn. var. rubro-plenus and its comprehensive development and utilization, the contents of K, Ca, Na, Mg, Fe, Mn, Cu, Zn, Cr, Ni were measured by the method of flame atomic absorption spectrometry (FAAS) in branches and leaves and flowers of Hibiscus rosa-sinensis Linn. var. rubro-plenus. The results showed that 10 elements existed in all the organs of the Hibiscus rosa-sinensis Linn. var. rubro-plenus. The order of the average content was: Ca>K>Na>Mg, Fe>Mn>Zn>Cu>Cr>Ni. The content of the element was different among 17 parts of Hibiscus rosa-sinensis Linn. var. rubro-plenus. The average content of Ca, Na, Fe, Mn, Zn and Cu in the Hibiscus rosa-sinensis Linn. var. rubro-plenus belonged to the normal content level of the elements in plants. The contents of Mg and K in the Hibiscus rosa-sinensis Linn. var. rubro-plenus. were relatively lower than that in the general plants, but the content of the Cr was relatively higher than that in the general plants. In addition, some parts of the plant did not include Ni element.
