Optimization of extraction process for compund kaliziran gel with orthogonal design / 中国中药杂志

<p><b>OBJECTIVE</b>To optimize the extraction process of compund kaliziran gel.</p><p><b>METHOD</b>Orthogonal design was used to optimize the extracting process of eight herb medicines with the extract yield, the content of psoralen, isopsoralen and osthole as indexes, and to optimize the extracting process of Polygonum multflorumi and Seman sinapis albae with the extract yield and the content of 2,3,5,4'-tetrehydroxy-stilbene glucoside as indexes.</p><p><b>RESULT</b>The optimum extraction progress was as follows:eight herb medicines were extract 2 times for 1 hour with 8 times of 60% alcohol; P. multflorumi and S. sinapis albae were extract 2 times for 1 hour with 8 times of 40% alcohol.</p><p><b>CONCLUSION</b>The optimum extraction processes are stable and feasible.</p>

Quality standard for Hanshi Tougu Tablet / 中成药

AIM: To establish the quality standard for Hanshi Tougu Tablets(Radix Aconiti Praeparata,Radix Aconiti Kusnezoffii Praeparata,Ramulus Cinnamomi,Rhizoma Atractylodis, Semen Sinapis,Radix Aucklandiae,Radix Glycyrrhizae). METHODS: Rhizoma Atractylodis,Semen Sinapis,Radix Glycyrrhizae in Hanshi Tougu Tablet were identified by TLC.The content of cinnamaldehyde and costunolide in Hanshi Tougu Tablets were determinded by HPLC. RESULTS: Rhizoma Atractylodis,Semen Sinapis,Radix Glycyrrhizae,Radix Aconiti Praeparata and Radix Aconiti Kusnezoffii Praeparata could be identified by TLC.Cinnamaldehyde showed a good linear relationship at the range of 2.104 ?g?mL~(-1)-52.60 ?g?mL~(-1),r=0.999 8(n=5), and the recovery was(99.62%,) RSD was(0.88%).Costunolide also showed a good linear relationship at a range of(0.036) mg?mL~(-1)-0.54 mg?mL~(-1),r=(0.999 9)(n=5),and the recovery was 96.10%,RSD was 0.15%. CONCLUSION: The method is simple,accurate and with strong specificity and can be used for the quality control of Hanshi Tougu Tablets.
