Abstract
In order to understand the difference of nutritional components between two species of Pyracantha Roem fruits in Sichuan Province, the contents of total sugar, Vc, protein, crude fibre, pectin, polyphenol and 12 kinds of main mineral elements in the fruits were determined by using the mature fruits of Pyracantha angustifolia and Pyracantha fortunaeana as material. The results showed that the basic nutrients of P. angustifolia and P. fortunaeana were complete. Except for crude fiber, other nutrients of P. angustifolia were higher than those of P. fortunaeana. The contents of 12 kinds of mineral elements in the two plants were abundant, and the contents of potassium (K), calcium (Ca), magnesium (Mg), zinc (Zn) and manganese (Mn) as beneficial mineral elements in P. angustifolia were higher than those of P. fortunaeana, while the contents of cadmium (Cd), chromium (Cr), nickel (Ni) and lead (Pb) as heavy metals in P. fortunaeana were higher than those of P. angustifolia. To sum up, the nutrient value of the fruits of P. angustifolia is higher than that of P. fortunaeana, which has more potential for exploitation and utilization
