摘　　要：以海南广藿香为试验材料,采用GC-MS对连作障碍下广藿香(连作组)和正常生长广藿香(对照组)在发育过程中的挥发油和百秋李醇含量的变化进行了分析。结果表明:连作组和对照组广藿香挥发油含量均随植株生长期的增加而逐渐增加,在210 d达到最高;生长150 d后,连作组广藿香的挥发油含量增长速度明显低于对照组。连作组和对照组广藿香挥发油中百秋李醇积累模式相似,均呈逐渐增加的趋势,在第210天含量达到最高。在广藿香的不同生长期,连作组广藿香油有效成分百秋李醇含量均低于对照组广藿香,质量更次。连作广藿香的挥发油含量和百秋李醇含量明显下降,为进一步研究提供了基础数据。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.
