Ultrasonic Assisted Extraction

Ultrasonic technology was applied to polysaccharides extraction from Ottelia acuminata (Gagnep.) Dandy and Response Surface Methodology (RSM) was used to optimize the effects of processing parameters on polysaccharides yields. Three independent variables such as liquid-solid ratio (ml/g, X1), extraction temperature (°C, X2) and extraction time (hour, X3) were investigated respectively. The statistical analysis indicated that the three variables and the quadratic of X1 and X3 had significant effects on the yields and followed by the significant interaction effects between the variables of X1 and X3, X2 and X3 (p<0.05). A mathematical model with high determination coefficient was gained. The optimal extraction conditions of polysaccharides were determined as follows: liquid-solid ratio 43 ml/g, extraction temperature 90 °C and extraction time 3.45 hours. Under these conditions, the experimental yield of polysaccharides was 107.44 mg/g, which was agreed closely with the predicted value 108.71 mg/g.

Ultrasonic assisted extraction (UAE) process increases the rate of extraction, the yield of extracted components and reduces extraction time. The high sensitivity of GC-MS/MS provides reliable identification of phytoconstituents present in a plant extract. This research is to develop an easy and effective method for the extraction and analysis of phytochemicals in C. singueana, C. sieberiana, C. tora and C. occidentalis using UAE and GC-MS/MS techniques. The crude extracts obtained from the four Cassia species under UAE conditions of 50 mins extraction time, 50 oC extraction temperature and 20 mL/g solvent to sample ratio were analyzed using GC-MS/MS. Thirty-four compounds were identified by comparison of their mass spectra with those in the National Institute of Standards and Technology library, requiring at least 80% similarity. These compounds comprise fatty acids, fatty alcohol, carboxylic acid, long-chain alkanes, diterpenes, triterpenes, sterols and anthraquinones. n-Hexadecanoic acid and phytol were identified in all the Cassia species while anthraquinone was detected only from the methanol extracts of C. tora and C. occidentalis. The bioactivities reported in the literature for these compounds corroborate with the phytoconstituents identified in these plants and support the ethnomedicinal uses of these Cassia species.

Because andrographis has a long history of folk medicine in Southeast Asian countries with antibacterial, antipyretic, antineoplastic, anti-inflammatory, cardioprotective effect and so on, the areas where andrographolia is introduced and cultivated are mainly concentrated. Espically andrographolide, neoandrographolide, andrographiside, homoandrographolide, andrographane, andrographanin, andrographone and andrographosterol that is concentrated in the leaves of the plant play the main medical role of andrographis. Of the above chemicals, andrographolide is the major bioactive constituent responsible for variety of activities. Leaves and stems of plant are used for extracting active phytochemicals; roots are used rarely. In this study, improved the extractability of andrographolide from the A. paniculata by ultrasonic assisted extraction, the optimum condition for extracted the andrographolide is determined by response surface experiment and detected the extractability of andrographolide under the optimum condition. By single factor analysis and response surface experiments, the optimum conditions for extracted the andrographolide were the extraction solution concentration 62.8%, the ultrasonic extraction time 59min, the ratio of solid to liquid 1:10.5 and the extraction temperature 62?. Investigate the andrographolide extractability in the optimun extraction condition by HPLC were increased from 2.27% to 3.28%.

We successfully extracted isoliquiritigenin from Glycyrrhiza uralensis through the utilization of an ionic liquid-based ultrasonic-assisted extraction (ILUAE) approach. Briefly, we utilized the solution of 1-butyl-3-methylimidazolium bromide ([BMIM]Br) as solvent and optimized key ILUAE parameters such as solid-liquid ratios, concentrations of ionic liquids, and the times of ultrasonication. Based on a single-factor experiment, we utilized the response surface method (RSM) approach to optimize the extraction procedure. The approach revealed that the optimal energy consumption time was 120 min, with the ultrasonic extraction temperature of 60°C. Using these optimized parameters together with the solid-liquid ratio (dried G. uralensis powder: [BMIM]Br of 0.3 mol/L) of 1 : 16.163 and the [BMIM]Br of 0.3 mol/L, we achieved a 0.665 mg/g extraction yield. Overall, these findings thus indicate that we were able to effectively use ILUAE as an efficient approach to reliably extract isoliquiritigenin in a reproducible and environmentally friendly manner.
