Abstract: OBJECTIVE To research the change of volatile oil and patchoulol content of continuous cropping Pogostemon cablin. METHODS In this paper,the dynamic accumulation mode of patchoulol and volatile oil content change during the development of P. cablin after continuous cropping( TR) and normal growth( CK) P. cablin were tested by GC-MS. RESULTS The essential oil contents in the two different cropping treatments showed growing trends from 90 to 210 days after cultivation( DAC) and reached their maximum levels at 210 DAC. The essential oil content in the TR group patchouli significantly lower than the CK group patchouli from 150 to 210 DAC. The patchoulol contents of TR group patchouli oil and CK group patchouli oil have the similar accumulation trends,showed growing trends from 90 to 210 DAC and reached their maximum levels at 210 DAC. The patchoulol contents in the TR group patchouli oil significantly lower than the CK group patchouli oil,during its different growth periods. CONDLUSIONS The contents of volatile oil and patchouli alcohol of continuous cropping of P. cablin decreased significantly. To provide reference data for further research.
