| 1 | Smashing Tissue Extraction and GC Analysis of Active Fatty Acids from Oil Cake of Perilla Seeds显示文摘Objective To optimize the extraction technology of perilla seeds oil from the oil cake of perilla seeds(OCPS)by using the contents of active fatty acids as evaluation standard.Methods The fatty acids were extracted from OCPS,the residue of perilla seeds after cold-press,by smashing tissue extraction(STE),the new technology selected through comparing with classical leaching extraction(LE),Soxhlet extraction(SE),ultrasonic extraction(UE),and supercritical-CO2 fluid extraction(SFE).For optimized condition of STE,orthogonal test was designed and completed.The contents of five fatty acids in extracted oil and OCPS were determined by GC.Results The optimized extraction parameters were smashing for 1.5 min under extraction power of 150 W and 1:6 of the material/solvent ratio.The contents of five fatty acids in the oils extracted by five techniques from OCPS and determined by GC were as follows:α-linolenic acid(41.12%-51.81%),linoleic acid(15.38%-16.43%),oleic acid (18.93%-27.28%),stearic acid(2.56%-4.01%),and palmitic acid(7.38%-10.77%).Conclusion The results show that STE is the most efficient technology with the highest yield(LE:0.57%;SE:1.03%;UE:0.61%;SFE:0.80%;STE: 1.17%)and shortest time(LE:720 min;SE:360 min;UE:30 min;SFE:120 min;STE:1.5 min)among five tested extraction technologies.It is first reported using STE to extract herbal oil enriched with active fatty acids. | SUN Yan-ling1,LIU Yan-ze2,3,XIAO Han4,WEI Ying-feng4,ZHAO Yu-qing1,5 1.Shenyang Pharmaceutical University,Shenyang 110006,China 2.Bio-organic and Natural Product Laboratory,MRC 311,McLean Hospital/Harvard Medical School,Belmont,MA 02478,USA 3.Institute of Medicinal Plant Development,Chinese Academy of Medical Sciences,Beijing 100193,China 4.Liaoning Jiashi Nutritional Plant Oil Development Co.Ltd.,Shenyang 110035,China 5.Key Laboratory of Structure-Based Drug Design&Discovery,Shenyang Pharmaceutical University,Ministry of Education,Shenyang 110016,China | 2011 | Chinese Herbal Medicines2011，3，1： | 5 |
| 2 | Smashing Tissue Extraction and HPLC Determination of Paclitaxel and 10-Deacetylbaccatin from Taxus x media显示文摘Objective To optimize the extraction technology of Taxus x media by using the contents of Paclitaxel and 10-deacetylbaccatin(10-DAB) ,two representative active diterpene alkaloids of taxane type from T.x media,as evaluation standard.Methods The smashing tissue extraction(STE) of Paclitaxel and 10-DAB from T.x media,was investigated by comparing with ultrasonic extraction(UE) which was one of the modern technologies of extraction.Results STE was more efficient than UE,and the contents of 10-DAB and Paclitaxel in the extracts obtained by STE were higher than those by UE.Conclusion STE is a fast,high-performance,and energy-saving technology for the extraction of diterpene alkaloids of taxane type.STE also provides a simple,component-safe,workable,and highly efficient method for the extraction of active natural product. | LIU Yan-ze1,2,GAO Wen-qin3,WANG Ji-wen4,ZHANG Yu3,ZHAO Yu-qing4,5 1.Institute of Medicinal Plant Development,Chinese Academy of Medical Sciences,Beijing 100193,China 2.Bio-Organic and Natural Product Laboratory,McLean Hospital/Harvard Medical School,MA 02478,USA 3.Shenyang Pharmaceutical University,Shenyang 110006,China 4.Shenyang Tianfeng Bioengineer Technology Co.,Ltd.,Shenyang 110015,China 5.Key Laboratory of Structure-Based Drug Design & Discovery,Ministry of Education,Shenyang Pharmaceutical University,Shenyang 110016,China | 2011 | Chinese Herbal Medicines2011，3，3： | 4 |
