To determine the representative weight of fresh needles per CO:COLLECTION_SUMMARY unit area in the forest of P. koraiensis, the tree canopy aboveground within one CO:COLLECTION_SUMMARY square meter was trimmed, and the fresh needles therein were weighed at five CO:COLLECTION_SUMMARY random points. The average weight (3980.58 g/m2) was then established as the CO:COLLECTION_SUMMARY representative weight of fresh needles per square meter. A weight of 84.03 g CO:COLLECTION_SUMMARY fresh needles were evenly laid on 2-layers absorbent gauze and fixed at the top CO:COLLECTION_SUMMARY of a 5-liter vessel (16.4 cm inside diameter), which was placed on the ground CO:COLLECTION_SUMMARY and filled with certain volume of double distilled water for simulated graded CO:COLLECTION_SUMMARY rainfall based on graded monthly precipitation. A peristaltic pump with a CO:COLLECTION_SUMMARY constant flow rate of 3770 ml/min was used to introduce the water to percolate CO:COLLECTION_SUMMARY through the packed fresh needle surface. The simulated leachates were filtered CO:COLLECTION_SUMMARY twice with qualitative filter paper via suction filtration and stored at 4 °C CO:COLLECTION_SUMMARY for quantification. CO:SAMPLE_TYPE Leaf leachate #TREATMENT TR:TREATMENT_SUMMARY A volume of 100 ml of leachates was extracted by 300 ml ethyl acetate then TR:TREATMENT_SUMMARY evaporated by rotary evaporator at 45°C with 4°C-condensed water recycled in TR:TREATMENT_SUMMARY low-temperature circulator. The remaining sediment was rinsed with 2.5 ml of TR:TREATMENT_SUMMARY hexane. The liquid hexane was filtered using a 0.22 um Millipore filter for TR:TREATMENT_SUMMARY further analysis. #SAMPLEPREP SP:SAMPLEPREP_SUMMARY After rotary evaporation, the remaining sediment was washed out with 5 ml of SP:SAMPLEPREP_SUMMARY ethyl acetate. The ethyl acetate was then filtered with a 0.22 um Millipore SP:SAMPLEPREP_SUMMARY filter for analysis. A series concentration of endo-borneol standard were SP:SAMPLEPREP_SUMMARY formulated in ethyl acetate to create a standard curve. #CHROMATOGRAPHY CH:CHROMATOGRAPHY_SUMMARY The temperature program started from an initial temperature of 50 ℃, followed CH:CHROMATOGRAPHY_SUMMARY by an increase of 12℃/min to 160 ℃.
