The results indicated that no bolting controlling treatment showed the best. The yield, the content of extraction and the essential oil increased by 67.80 %, 2. 12 % and 26. 19 % from root of N. forbesii compared with the control. However, the worst treatment was getting rid of bolting treatment. The extraction content of treatments above mentioned and the control reached the requirement of China Pharmacopoeia（15%）; however, the essential oil content showed a lower level than that in China Pharmacopoeia（0. 028 mL・g. 1）.
