目的 合理开发利用浙江雪胆资源.方法 对目前中药雪胆的化学成分、药理作用、临床应用及不良反应进行总结,拟定研发浙江雪胆的思路.结果 与结论浙江雪胆具有很高的药用价值潜力,但为濒临灭绝的稀有物种,对其开发研究提出一些建议.

粉体是由很多单个固体粒子组成的集合体,是固体的特殊形态,它具有一些特殊的物理性质,例如粉体的流动性、吸湿性、充填性、凝聚性、带电性、巨大的比表面和很小的松密度等.测定粉体的流动性并进一步改善它的流动性,对粉体的生产工艺、传输、储存、装填以及巾药制剂中的不同成分的混合、颗粒剂、片剂、散剂、胶囊剂等等的成型及装量有着重要的意义.

[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 curcumol in Curcuma aromatica Salisb.
