Abstract Loquat is a kind of economic fruit with very high medicinal value. Researches on geochemical characteristics of elements in loquat from several areas with different mother rock types show that the elements are concentrated in different organs of loquat, and that different species of loquat are enriched in approximately the same sorts of elements, with somewhat different degrees of enrichment. Beneficial and nutritional elements are more concentrated in leaves than in other organs. Harmful elements do not exceed the standard. N, P, K, Ca, Mg, B, Zn and Cu make up the main nutritional elements for loquat fruit.
