Abstract: In order to further promote the development and utilization of Oroxylum indicumresources,the contents of amino acids and mineral elements in different parts of Oroxylum indicum fruits at different periods were determined by automatic amino acid analyzer and inductively coupled plasma atomic emission spectrometry.The results showed that there were 17 kinds of amino acids（8 essential amino acids and 9 medicinal amino acids）in different parts of Oroxylum indicumfruit during mature and fresh eating periods.The content of total amino acids in different parts of Oroxylum indicumfruit at different periods was as follows:seeds and wings at fresh eating period ＞ wings at mature periods＞pericarp at fresh eating period ＞ pericarp at mature periods＞seeds at mature periods;12 kinds of mineral elements were detected in different parts of Oroxylum indicumfruit at maturity,and the contents were Ca＞Mg＞As＞Pb＞Fe＞Cu＞Zn＞Mn＞Ni＞Cr＞V＞Cd.The content of mineral elements in different parts of Oroxylum indicumfruit was wing＞seed＞fruit.
