Its lumber material is narrow for the alburnum, distributes in north compared to the south narrowly, light yellow arrives the yellow light yellow, the heartwood to brown brings slightly red; Has the resin, the durability is bad; The lumber texture, the density, standard natures and so on the festival receive the geography condition influence which grows, is widespread as a result of this lumber distribution, but therefore the lumber material the variation is greatly more obvious than because of the condition other tree seeds; The lumber weight is ordinary, solid.

其木材材性为边材窄，分布在北部的比南部的更窄，浅黄到黄色，心材浅黄至褐色略带红色；有树脂，耐久性差；木材的纹理、密度、节子等格质均受生长的地理条件影响，由于该木材分布广泛，所以木材的材性因条件而变异大比其他树种明显；木材重量一般，较结实。

The optimal separating condition of chromatography analysis was: Shimadzu VP-ODS 150mm4.6mm as chromatographic column; acetonitrile/water (12/88,V/V, Contained 1.25mmol/l phosphoric acid) as mobile phase with flow rate of 1.0ml/min. Macroporous ion exchange resins and activated carbon were applied to enrich the trace level impurities and the main impurities was determined by LC-MS and GC-MS.They were : Benzonitrile , 2-Methyl-8-hydroxyquinoline, 2,6-Pyridinediamine , O-ethyloxime Cyclo-hexanone and compound with 220 molecular weight .
