Nine compounds, or 4 kinds of compounds in methanol extract were identified, including phenols(3 types, 20.344%), esters(4 types, 48.169%), acid(1 type, 11.740%), phenanthrene(1 type, 8.345%). Nineteen compounds, or 7 kinds of compounds in acetone extract were identified, including phenols(8 types, 19.965%), phenanthrenes(4 types, 8.987%), acids(2 types, 15.738%), esters(2 types, 16.160%), indene(1 type, 3.172%), naphthalene(1 type, 0.550%), and alkene(1 type, 0.504%).
