The data obtained by the anna- lysis of volatile compounds are identified by Nist Dababase. There are 34 kinds of compositions identified from the leaves, which are mainly 10 ketonecompounds, 7 aldehydecompounds, 6 ester compounds, 2 alkane compounds, 4 alcohol compounds and 5 naphthalene compounds. They make up 39.59% and 23.69%, 14.16%, 12.41%, 4.22% and 4.65% of the identified compositions respectively. The main components from the leaves were Farnesylacetone (11.74%), Phenanth- rene (10.60%), Beta-Ionone (7.23%). There are 31 kinds of compositions identified from the culm, which are mainly 16 ester compounds, 5 ketonecompounds, 2 phenolcompounds, 4 alcohol
