| 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. |

| MS Comments: | An electron ionization system with ionization energy of 7 eV was used. Helium gas (99.999%) was used as the carrier gas at constant flow rate 1 ml/min and an injection volume of 1 ul was employed. The ion-source temperature was 230 °C. The scan interval of mass spectra was 3.1 units/s and fragments from 35 to 270 da. Afterwards, Agilent MassHunter Workstation Quantitative Analysis B.07.01 were used as analytical software. The mass spectrum of the individual peak was inspected manually to confirm the peak had the correct m/z diagnostic fragments, matched with the search results from NIST MS Search 2.2 library. For endo-borneol, the target ion is m/z 95, and qualifier ions are m/z 110 and m/z 67. |
