Study ID	ST003309
Study Title	Needle leachates of Pinus koraiensis from May to September
Study Summary	To study the allelopathy in agroforestry system (Pinus koraiensis and Panax ginseng in this context), we identified the compounds of the needle leachates during the growing season of Panax ginseng (May~September). Three replicates were set for each month, leachates were extracted with ethyl acetate and concentrated for GC-MS analysis. As a result, a total of 795 metabolites were identified in all the samples.

Sample Preparation:

Sampleprep ID:	SP003437
Sampleprep Summary:	A volume of 100 ml of leachates was extracted by 300 ml ethyl acetate (Analytical grade, Tianjin Fengchuan Chemical Reagent Co., Ltd, 426 Tianjin, China) then evaporated by rotary evaporator at 45°C with 4°C-condensed water recycled in low-temperature circulator. The remaining sediment was 429 rinsed with 2.5 ml of hexane (HPLC, EMD Millipore, Billerica, MA, USA). The liquid hexane was filtered using a 0.22 um Millipore filter (Catridge filter, Jin Teng, China) for gas chromatography-mass spectrometry (GC-MS) analysis.
