Abstract：Vascular bundle of Citrus fruit is the tissue between citrus albedo and segment epidermis, mediating the nutrients and water transport between flesh and rind. Such vascular bundle is well-known traditional Chinese medicine with multiple curative effects. The present study was performed to analyze the morphology and relative water content of the vascular bundle of Citrus fruit, and further the atomic absorption spectrometry was employed to elucidate several mineral elements contents (K, Ca, Mg, Cu, Zn) in vascular bundle of mandarin and Ponkan mandarin fruit. After brief discussion, several conclusions was made as follows: (1) Relative water content of the vascular bundle was (63.57%±1.53%) in Satsuma mandarin, which was much lower than that in Ponkan mandarin (70.25%±0.24%). (2) Content of K, Ca, Mg in vascular bundle was 3 525～6 495, 6 866～9 430, 394～632 mg·kg-1, respectively in terms of dry weight. Concentration of Cu and Zn in the vascular bundle was 1.5～2.3 and 8.5～14.7 mg·kg-1 , respectively in terms of dry weight. (3) Content of K, Ca, Mg, Zn was relatively higher in vascular bundle of Ponkan mandarin than that of Satsuma mandarin. The present results suggested a well correlation between mineral elements contents in vascular bundle and the water content of fruit, contributing to further research of section-drying in Citrus fruits, as well as deep utilization of this promising resource.
