用可见分光光度法与等离子体发射光谱法对他人掌果汁色素及其微量元素的含量进行了测定，仙人掌果汁色素含量达2．1％～3．3％，成熟果的果汁色素含量比预成熟果大。在27种被测定的元素中，除AS，Be，Cd，Co，Mo，Ph，Sb，Tl等未被检出外，其余Ag，Al，B，Ba，Ca，Cr，Cu，Fe，Mg，Mn，Na，Ni．Se，V，Zn，K，P，S等均有准确测定值。成熟果与预成熟果的果汁微量元素含量无明显差异。 Spectrophotometry and plasma emission spectrometry were used to determine the content of pigments and their trace elements in juices of other persons. The content of pigments in cactus juices was 2.1%-3.3%, and the coloring of fruit juices in mature fruits was higher than pre-maturation. Big fruit. Of the 27 elements that were measured, except Ag, Al, B, Ba, Ca, Cr, Cu, Fe , Mn, Na, Ni. Se, V, Zn, K, P, S, etc. all have accurate measurements. There was no significant difference in the trace element content of fruit juice between ripe fruit and pre-mature fruit.
