不同生长期的温莪术中挥发油含量比较

To Compare the Content of the Volatile Oil from Curcuma Aromatica Salisb. of Different Growth Periods

[目的]研究不同生长期对温莪术中挥发油含量及挥发油中莪术醇含量高低的影响，为控制温莪术中药材的质量提供理论的依据。[方法]采用药典法提取并测定不同生长时期的温莪术鲜品中挥发油含量，运用RP—HPLC法测定挥发油中莪术醇含量。[结果]不同生长期的温莪术鲜品中挥发油含量在0．471％～0．820％（g／g）之间，挥发油中莪术醇含量在0．862％～1．380％（g／g）之间。[结论]生长期长的温莪术中挥发油及油中莪术醇的含量均高于生长期更短的温莪术，生长期的长短会影响到温莪术中挥发油和莪术醇有效成分的积累．

[Objective] To study the effects of different growth periods on the contents of volatile oil and the curcumol in Curcuma aromatica Salisb. samples,which provided theoretical bases to control the quality of the crude drug of Curcuma aromatica Salisb. [Method]The contents of volatile oil in Curcuma aromatica Salisb. samples were determined by the method of Pharmacopeia,and HPLC method for determination of curcumol in different samples was established. [Result]The contents of volatile oil in different samples lied in the range of 0. 820 %-0. 471 % （g/g）, and the contents of curcumol in different volatile oil samples were between 0. 862% （g/g） and 1. 380 % （g/g）. [Conclusion]Compared with the Curcuma aromatica Salisb. of a shorter growing period,the contents of longer growth period were higher. Different growing time had effects on the accumulating of volatile oil and the curcutool in Curcuma aromatica Salisb.
