“…Já que constitui uma das etapas mais importantes no isolamento, identificação e aplicação de compostos fenólicos, os métodos de extração tem sido diversificados desde os métodos tradicionais através do uso de solventes (extração líquido-líquido, sólido-líquido), como métodos não convencionais (extração por fluido supercrítico, extração por ultrassom, extração mecânico-química, extração por micro-ondas, extração com infravermelho e extração com líquido pressurizado) (Chua, 2013, Xie et al, 2011, Liu et al, 2014. Independentemente da técnica de extração, a extração sólido-líquido ocorre em dois estágios: (1) tumefação e hidratação da matriz vegetal e (2) transferência de massa do soluto a partir da matriz vegetal para o solvente por difusão e pressão osmótica (Vinatoru, 2001).…”

“…Cada método possui vantagens e desvantagens, cuja escolha influencia diretamente o rendimento e a pureza do soluto. As principais variáveis que influenciam no processo são temperatura, razão sólido-líquido, tempo de extração, número de ciclos e concentração e tipo de solvente (Liu et al 2014, Xie et al, 2011. Em estudo da otimização de extração sólido-líquido de flavonoides totais a partir de Scutellaria baicalenses, Liu et al (2014) obtiveram um rendimento de 19,437 mg flavonoides/g massa seca em condições otimizadas.…”

formulações industriais é limitada devido à baixa solubilidade em meios lipofílicos. A esterificação por lipases tem sido utilizada para melhorar as propriedades dos flavonoides. Desta forma, avaliou-se a espécie Passiflora edulis (maracujá) como matéria-prima para obtenção de flavonoides que serão submetidos à esterificação utilizando lipase de Candida antarctica tipo B (CALB) imobilizada em nanoparticulas magnéticas e cujos resultados serão comparados com CALB imobilizada em resina acrílica comercial. Os extratos etanólicos foram obtidos por extração sólido-líquido da casca do maracujá seca que, após evaporação do solvente, foram liofilizados e armazenados a 4 ºC. Determinouse o teor de flavonoides em HPLC empregando detector UV/PDA. Obteve-se 35 mg/L de flavonoides nos extratos, indicando o potencial do maracujá como fonte destes antioxidantes.

Background:A method for chemical fingerprint analysis of Hibiscus mutabilis L. leaves was developed based on ultra performance liquid chromatography with photodiode array detector (UPLC-PAD) combined with similarity analysis (SA) and hierarchical clustering analysis (HCA).Materials and Methods:10 batches of Hibiscus mutabilis L. leaves samples were collected from different regions of China. UPLC-PAD was employed to collect chemical fingerprints of Hibiscus mutabilis L. leaves.Results:The relative standard deviations (RSDs) of the relative retention times (RRT) and relative peak areas (RPA) of 10 characteristic peaks (one of them was identified as rutin) in precision, repeatability and stability test were less than 3%, and the method of fingerprint analysis was validated to be suitable for the Hibiscus mutabilis L. leaves.Conclusions:The chromatographic fingerprints showed abundant diversity of chemical constituents qualitatively in the 10 batches of Hibiscus mutabilis L. leaves samples from different locations by similarity analysis on basis of calculating the correlation coefficients between each two fingerprints. Moreover, the HCA method clustered the samples into four classes, and the HCA dendrogram showed the close or distant relations among the 10 samples, which was consistent to the SA result to some extent.

“…Also, the extraction of rutin from Hibiscus mutabilis (Xie and Shi et al, 2011) was conducted by the mechanochemicalassisted extraction technology. Mechanochemical grinding was also conducted to make the quartz particle to be a surface-active material for the efficient extraction of desired materials (IImura et al, 2007;Palaniandy and Azizli, 2009;Zubrik et al, 2007).…”

-Saururus chinensis is used as a raw material of an anti-rheumatic, poultice, sedative and stomachic. The tea of dried Saururus chinensis leaves has a function of relaxing pains in back and breast and of treating stomach ailments. The plant has the functions of anti-inflammatory, depurative, diuretic, febrifuge and refrigerant. The extraction of functional material is carried out by methanol and ethanol solvents. Mechanochemical grinding is applied as a pretreatment process before extraction to enhance the extraction efficiency by increasing the surface area of the materials while changing the chemical properties of the materials. Extraction of functional materials from the Saururus chinensis after grinding as a pretreatment using the mechanochemical technology was accomplished in this study to investigate the effect of grinding on the antioxidant activities of the extract. Saururus chinensis was ground by the planetary ball mill and the morphology was analyzed by SEM. Mechanochemical pretreatment increased the yields of functional materials from 5.9 g to 6.4, 7.0, and 8.1 g after grinding of 30 minutes, 1 hour and 2 hours, respectively. Nitrite scavenging ability increased from 53.0-71.0% to 61.0-79.0% for the methanol extraction in the solution of pH 1.2. Also, Electron donating abilities were increased from 7.90-33.51% to 11.97-38.51% for the methanol extraction. The extract concentration for the half inhibition of DPPH radicals was reduced from 278 μg/mL in the original sample to 263 μg/mL in the sample after grinding for the methanol extraction.
