| Abstract: | A mixture of Sugi (Cryptomeria japonica) wood and bark was steamed at 150 ℃ and 5 atm for 90 min. The steaming solution was collected from the waste drain of steaming kiln. The steaming solution was extracted with hexane and ethyl acetate. The steaming solution was adsorbed on polystyrene resin adsorbent HP20 and the adsorbate was desorbed with methanol and ethyl acetate.
Gas chromatography-mass spectrometry (GC-MS) analysis of the hexane extract, the ethyl acetate extract and the HP20 adsorbate revealed 55 compounds such as terpenes, phenols and furans in the steaming solution. From the HP20 adsorbate, sequirin C and agatharesinol of norlignans were isolated by column chromatography and preparative thin layer chromatography.
The residue solutions after solvent extraction and HP20 adsorption of the steaming solution were freeze-dried and were ignited. The ash content was analyzed by inductively coupled plasma atomic emission spectrometer (ICP) and Na, K, Ca, Si, Fe, Mg, P, Zn, Al, B and Mn were detected. |
