[Objective] To discuss the effect of different vinegar-prepared corydalis tuber on betaeellulin and solid Matter. [Method] Select real dry crude drugs corydalis tuber for preparation separately with 18℃ Qinghua white vinegar, 4℃ Longmen rice vinegar, Zhenjiang rice vinegar, Tianjin Cuibo rice vinegar, 4℃ Zhenji and Shanghai Tianyu rice vinegar under “China Pharmacopoeia"; take LC to measure the contents of betacellulin and .solid matter. [Result] The different influences on betacellulin are as follows: 18℃ Qinghua white vinegar＞4℃ Longrnen rice vinegar＞ Zhenjiang rice vinegar＞ 4℃ Zhenji＞ Shanghai Tianyu rice vinegar; on solid matter: Shanghai Tianyu rice vinegar ＞ Tianjin Cuibo rice vinegar＞ Zhenjiang rice vinegar＞4℃ Zhenji＞4℃ Longmen rice vinegar＞ 18℃ Qinghua white vinegar; the differences are very marked. [Conclusion] The different influence will affect the medicinal values.%[目的]探讨不同品种醋炮制元胡对延胡索乙素提取率和固形物的影响.[方法]选用延胡索正品药材的干燥块茎分别用18℃青花白醋、4℃龙门米醋、镇江米醋、天津翠波米醋、4℃珍极、上海天鱼米醋,按<中国药典>2005版延胡索炮制方法制备:每种醋平行炮制6份,每份500g元胡;采用液相色谱法测定元胡炮制品中延胡索乙素及固形物的含量.[结果]不同品种醋对元胡药材中延胡索乙素提取率的影响:18℃青花白醋＞4℃龙门米醋＞镇江米醋＞天津翠波米醋＞4℃珍极＞上海天鱼米醋,对固形物得率的影响:上海天鱼米醋＞天津翠波米醋＞镇江米醋＞4℃珍极＞4℃龙门米醋＞8℃青花白醋,且不同品种醋对元胡药材中延胡索乙素提取率和固形物得率的影响,存在显著性差异(P＜0.05).[结论]不同品种醋炮制元胡可影响其有效成分延胡索乙素的提取率和固形物的得率,从而影响其药用价值.
