目的：考察不同干燥方法对丹参乙醇提取物中丹参酮ⅡA含量的影响。方法：采用薄层扫描法测定。结果：在70℃温度下，减压干燥丹参酮ⅡA损失约24%；常压干燥损失约77%。结论：减压干燥可明显减少丹参酮ⅡA的损失。
目的：攷察不同榦燥方法對丹參乙醇提取物中丹參酮ⅡA含量的影響。方法：採用薄層掃描法測定。結果：在70℃溫度下，減壓榦燥丹參酮ⅡA損失約24%；常壓榦燥損失約77%。結論：減壓榦燥可明顯減少丹參酮ⅡA的損失。
목적：고찰불동간조방법대단삼을순제취물중단삼동ⅡA함량적영향。방법：채용박층소묘법측정。결과：재70℃온도하，감압간조단삼동ⅡA손실약24%；상압간조손실약77%。결론：감압간조가명현감소단삼동ⅡA적손실。
The contents of tanshinone Ⅱ A in ethanol extracts which were dried with different methods (ordinary pressure and depression 640 mmHg under same temperature 70℃) were observed. Quantitative analysis of tanshinone ⅡA was performed by TLC-scanning. The results showed that the best way was to use depression with the less loss of tanshinone ⅡA than ordinary pressure, and it could be a theoretical bases for preparing procedure of Radix Salviae Mitiorrhizae in compound.
