| Study Title | Determination the concentration of endo-borneol from needle leachates of Pinus koraiensis flushed by precipitation via indoor simulated leaching) |
| Study Summary | The precipitation from April to October (2016-2021) was provided by local weather burea in Benxi. The monthly precipitation and duration in Benxi is classified into high, medium, and low level. Under each precipitation, the concentration of endo-borneol is quantified by indoor simulated leaching. The simulated leachates were extracted by ethyl acetate and then analyzed by GC/MSD. As a result, the peak area of endo-borneol ranges from 2006.257 to 27106.75 under tested precipitation. |

| Collection Summary: | Based on historical meteorological data, monthly precipitations were graded as low (34.6 mm, 771.63 min), medium (104.2 mm, 2223.07 min) and high (285.8 mm, 5233.03 min) level. To determine the representative weight of fresh needles per unit area in the forest of P. koraiensis, the tree canopy aboveground within one square meter was trimmed, and the fresh needles therein were weighed at five random points. The average weight (3980.58 g/m2) was then established as the representative weight of fresh needles per square meter. A weight of 84.03 g fresh needles were evenly laid on 2-layers absorbent gauze and fixed at the top of a 5-liter vessel (16.4 cm inside diameter), which was placed on the ground and filled with certain volume of double distilled water for simulated graded rainfall based on graded monthly precipitation. A peristaltic pump with a constant flow rate of 3770 ml/min was used to introduce the water to percolate through the packed fresh needle surface. The simulated leachates were filtered twice with qualitative filter paper via suction filtration and stored at 4 °C for quantification. |
