In this study, response surface methodology (RSM) was used to optimize the ultrasonic-assisted extraction parameters of Sojae Semen Praeparatum polysaccharides (SSPP-80), the optimum conditions were determined as follows: ultrasonic frequency of 100 W, ultrasonic power of 80 Hz, ultrasonic temperature of 52℃, ultrasonic time of 23 minutes, and liquid to raw material ratio of 40 mL/g. Based on these conditions, polysaccharides extraction rate was 7.72% ± 0.26%. Then, 2 novel polysaccharides (SSPP-80‐1, SSPP-80‐2) were isolated from SSPP by DEAE-cellulose 52 chromatography. The chemical compositions, physicochemical properties, and structure of SSPPs were investigated by simultaneous thermal analyzer (TGA), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FI-IR), and high-performance liquid chromatography (HPLC). The results showed that SSPP-80 and 2 fractions were mainly composed of mannose (Man), glucose (Glc), galactose (Gal), xylose (Xyl), and arabinose (Ara). In addition, the antioxidant activities were evaluated against the DPPH and hydroxyl radical in vitro, the IC50 of SSPP-80, SSPP-80‐1 and SSPP-80‐2 against DPPH free radical were 4.407, 8.267, and 5.204 mg/mL, respectively, whereas the IC50values for removing hydroxyl groups were 5.318, 3.516, and 4.016 mg/mL, respectively. It demonstrated that SSPP-80 and 2 fractions had certain antioxidant activity. Theoretical basis for use of Sojae Semen Praeparatum polysaccharides was provided by this study.

Ionic liquids (ILs), known as environmentally benign “green” solvents, were developed as an optimal solvent for the green extraction and separation field. In this paper, an ionic liquid-based ultrasonic-assisted extraction (IL-UAE) of flavonoids (FVs) from bamboo leaves of Phyllostachys heterocycla was developed for the first time. First, 1-butyl-3-methylimidazolium bromide ([Bmim] Br), with the best extraction efficiency, was selected from fifteen ionic liquids with diverse structure, like carbon chains or anions. Then, the influencing parameters of ionic liquid (IL) concentration, liquid-solid ratio, ultrasonic time, and ultrasonic power, were investigated by single factor tests, and further optimized using response surface methodology (RSM). In the optimization experiment, the best conditions were 1.5 mol/L [BMIM]Br aqueous solution, liquid-solid ratio 41 mL/g, ultrasonic time 90 min, and ultrasonic power 300 W. Furthermore, the microstructures of bamboo leaves and the recovery of FVs and [BMIM]Br were also studied. Therefore, this simple, green and effective IL-UAE method has potentiality for the extraction of FVs from bamboo leaves for the large-scale operations.

Psoralea Fructus is widely used in traditional Chinese medicine (TCM), and the content of psoralen, isopsoralen, neobavaisoflavone, bavachin, psoralidin, isobavachalcone, and bavachinin A is the main quality control index of Psoralea Fructus because of its clinical effects. Thus, a fast and environmentally-benign extraction method of seven compounds in Psoralea Fructus is necessary. In this work, an ionic liquid-based ultrasonic-assisted method (ILUAE) for the extraction of seven compounds from Psoralea Fructus was proposed. Several ILs of different types and parameters, including the concentration of ILs, concentration of ethanol (EtOH), solid–liquid ratio, particle size, ultrasonic time, centrifugal speed, and ultrasonic power, were optimized by the Placket–Burman (PB) design and Box–Behnken response surface analysis. Under this optimal condition, the total extraction yield of the seven compounds in Psoralea Fructus was 18.90 mg/g, and significantly greater than the conventional 75% EtOH solvent extraction.

The present study was embarked upon for the optimization of conditions aimed at ultrasonic assisted extraction (UAE) of antioxidant chemicals from Moringa oleifera leaves by applying response surface methodology (RSM) based on face centered central composite design (CCD). Evaluation was done at three levels (20 experimental designs) with three process variables: extraction temperature (20, 30, 40oC), extraction time (20, 30, 40 min) and liquid-solid ratio (20:1, 30:1, 40:1) using probe sonicator. The extraction process optimization based on RSM was focused on the capacity of antioxidants present in the extracts to scavenge the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) free radicals. To envisage the optimization process, multiple regression analysis was carried out using RSM tool to obtain a quadratic polynomial equation. Stastical analysis of the factors and their interactions were tested using analysis of variance (ANOVA). Extraction of antioxidants was mainly influenced by liquid-solid ratio and temperature. The ideal combination of variables designed by RSM for maximum radical-scavenging activity was optimized with extracting temperature of 39.80 °C, extracting time of 39.95 min and liquidsolid ratio of 24.00 mL/g to obtain a predicted value of 85.528% of DPPH radical-scavenging activity, which was very close to the experimentally value of 86.49 % with an error of 1.12%, indicating suitability of the model.

Medicinal plants are good sources and rich of substances which having nutraceutical and health benefits. Valeriana officinalis L. (Valerianaceae) is a known medicinal plant used in traditional medicine worldwide. The aim of present study was to evaluate the efficiencies of three methods for evaluated for antioxidant from Valeriana officinalis. Besides, the impact of extraction methods on total phenollic and flavonoids contents and antioxidant activities of Valeriana root was investigated. The dried-root was extracted by three different methods including maceration, ultrasonic assisted, and Soxhlet assisted extraction. Antioxidant capacity was assessed using four different methods: DPPH and nitric oxide (NO) free radicals scavenging, reducing power and iron chelating activity. The total phenolic and flavonoid contents were also identified. The ultrasonic extract showed highest amount of total phenolics and flavonoids contents. In DPPH radical scavenging activity, the ultrasonic assisted extract, (IC50=0.546 μg/ ml) had a higher activity from other extracts. In reducing power assay, maceration extract showed the highest activity. In DPPH radical scavenging activity, IC50 for ultrasonic extract, soxhlet assisted extraction and maceration extract were 0.546, 0.816 and 0.678 μg/ml, respectively. Here, the maceratin extract showed the highest activity, too. The results clearly indicated the extraction methods used in this study significantly affected antioxidant capacities and total phenolic and flavonoids contents. Ultrasonic assisted extraction and Soxhlet methods were found to be more efficient in extraction of antioxidant components of valeriana.
