| 1 | 用传统和超声提取的松果菊(紫锥菊属)的抗氧化和抗菌活性(英文)显示文摘Antioxidant and antimicrobial activities of Echinacea purpurea L. (Asteraceae) extracts obtained by classical and ultrasound solvent extraction were compared. The dry aerial part of plant was extracted by 70% etha-nol at a solid-to-liquid ratio of 1︰10 (m/v) and 25°C. The extract obtained by classical solvent extraction contained 29% larger amounts of phenolic compounds and 20% higher content of flavonoids. 2,2-diphenyl-1-picril hydrazyl radical (DPPH) scavenging reached 93.6% and the values of EC50 were (34.16±0.65) μg·ml-1 and (65.48±1.12) μg·ml-1 for the extracts obtained by the classical and ultrasound extractions, respectively. The extracts, independent of the extraction technique applied, showed a considerable growth inhibition on Candida albicans and Saccharo-myces cerevisiae, while no growth inhibition zones were observed for Aspergillus niger. The diameters of inhibition zone observed for all the microorganisms were larger for extracts obtained by classical extraction than those by ul-trasound extraction. | Ivana Stanisavljevi Sаa Stojievi Dragan Velikovi Vlada Veljkovi Miodrag Lazi | 2009 | Chinese Journal of Chemical Engineering2009，17，3： | 2 |

| 3 | 不同萃取技术获得的Artemisia sp的甲醇提取物其抗氧化和抗菌活性的比较(英文)显示文摘The polyphenol content,antioxidant and antimicrobial activities of the extracts obtained by classical, ultrasonic and Soxhlet extractions from dry aerial parts of two Artemisia species(Artemisia vulgaris and Artemisia campestris)were compared.Ultrasound positively affected the yield of extractive substance and the kinetics of extraction,but the extract obtained by the classical extraction showed the highest antioxidant activities and contained higher total contents of phenolic compounds and flavonoids than the extracts obtained by two other extraction techniques.Both flavonoid aglycones(apigenin,quercetin,quercetin 3,3′-dimethyl ether)and flavonoid glycosides(rutin,hyperoside and kaempferol 3-rhamnoside)were identified by thin layer chromatograph(TLC)analysis in the extracts from both species.A.campestris extracts were richer in quercetin than A.vulgaris and its antimicrobial activity was also better than A.vulgaris.Extracts obtained from both species were found to be more effective on the tested yeasts than bacteria.The kinetics of the total extractive substances,such as phenolic,flavonoids and quercetin extraction,was successfully described by the model of unsteady-state diffusion. | Ivana Karabegovi Milena Nikolova Dragan Velikovi Sаa Stojievi Vlada Veljkovi Miodrag Lazi | 2011 | Chinese Journal of Chemical Engineering2011，19，3： | 1 |
