Quantitative analysis of trace elements in Podocarpus nagi seeds

Podocarpus nagi is a tree belonging to the family of Podocarpaceae, which has ever been used for treatment of trauma, stop-bleeding, fractures, knife wounds, gunshot wounds, body odor, eye diseases, colds and rheumatoid arthritis in clinic. Some compounds have been isolated and their biological activities were also evaluated. it’s seeds contains much oil and which can be used for food after refining or directly used industrially. In this work, the trace elements in the nuts, nut shell and oil residue were detected by the method of atomic absorption spectrum, which can provide reference for the further study. *Correspondence to: Jianping Yong, Xiamen Institute of Rare-earth Materials, Haixi Institute, Chinese Academy of Sciences, Xiamen, 361021, China, Tel: +86-591-63173162, E-mail: jpyong@fjirsm.ac.cn Canzhong Lu, Xiamen Institute of Rare-earth Materials, Haixi Institute, Chinese Academy of Sciences, Xiamen, 361021, China, Tel: +86-591-83705794, E-mail: czlu@fjirsm.ac.cn
