On the sawn and dried cross-sectional surface of Cunninghamia konishii Hayata there are often a lot of white needle crystals appearing. The analytical results from the GC, FT-IR, (superscript 1)H-FTNMR, (superscript 13)C-FTNMR, GC-MS and polarimetry, indicate that the white needle crystal is nearly pure cedrol (99.12%, octahydro-3,6,8,8-tetramethyl-1H-3α, 7-methanoazulen-6-ol).
