Microwave digestion-inductively coupled plasma astigmatism (ICP-AES) was used to analyze the contents of mineral elements (including K, P, Mg, Ca, Na, Fe, Cu, Mn, B, Zn, Se, Li) in 54 Olecranon Peaches collected from Shangping town, Lianping County. The obtained data was analyzed by Correlation analysis (CA), combined with fruit reducing sugar (RS%), sugar-acid ratio (S/A) and sensory scores. The results showed that in the tested samples, it had a significant positive correlation between S/A sugar-acid ratio and sensory evaluation. S/A was negatively correlated with P contents. The P contents were positively correlated with the K, Mg contents. The Mg contents were positively correlated with the K, Na contents. The Na contents were positively correlated with the Mn contents. The contents of Mn were positively correlated with RS% ratios of reducing sugar.
