Research on identification of Pterocarpus santalinus by GC-MS
A new method to identify Pterocarpus santalinus was established by extracting wood with ethyl acetate and analyzing the extractives with gas chromatography-mass spectrometry (GC-MS).Experiments on P.santalinus and 6 imitating species showed that chemical composition variation of the extractives were small within species but significant among species.All the 6 imitating species exhibited different characteristic chemical components compared with those of P.santalihas.This identification method was easy to perform,efficient as well as eco-friendly,and could be used as a complementary method to identify P.santalinus and other precious species.
