Optimisation of ultrasound assisted extraction of phenolic compounds from Sparganii rhizoma with response surface methodology

Abstract

The present study reports on the extraction of phenolic compounds from sparganii rhizome. Box-Behnken Design (BBD), a widely used form of response surface methodology (RSM), was used to investigate the effect of process variables on the ultrasound-assisted extraction (UAE). Three independent variables including ethanol concentration (%), extraction time (min) and solvent-to-material ratio (mL/g) were studied. The results showed that the optimal UAE condition was obtained with an ethanol concentration of 75.3%, an extraction time of 40min and a solvent-to-material ratio of 19.21mL/g for total phenols, and an ethanol concentration of 80%, an extraction time of 33.54min and solvent-to-material ratio of 22.72mL/g for combination of ρ-hydroxybenzaldehyde, ρ-coumaric acid, vanillic acid, ferulic acid, rutin and kaempferol. The experimental values under optimal conditions were in good consistent with the predicted values, which suggested UAE is more efficient process as compared to solvent extraction.

Optimization of mango seed kernel oil extraction using response surface methodology

“…Rodrigues et al (2008) reported that the greatest effect on TPC of extracts was promoted by the solid-liquid ratio and the temperature. Cacace and Mazza (2003) and Wang et al (2013) reported that solidliquid ratio is the most significant parameter affecting of TPC. According to Ghafoor et al (2009), the solubility of phenolic compounds increases with increasing of temperature and extraction time.…”

“…Previous studies showed that temperature, time and amount of solvent were the main parameters affecting the extraction yield from different sources (Li et al, 2012;Goula, 2013;Minjares-Fuentes et al, 2014). These parameters also had a significant influence on the endogenous bioactive compounds, such as certain from the TPC (Rodrigues et al, 2008;Ghafoor et al, 2009;Wang et al, 2013;Sahin and Samli, 2013;Chanioti et al, 2016).…”

Optimization of microwave-assisted extraction of ergosterol from Agaricus bisporus L. by-products using response surface methodology

“…Conventional methods used for many decades include Soxhlet extraction, maceration, and percolation, among others. They are often time-consuming and require large quantities of solvents, including hazardous ones (Wang et al, 2013). Emerging technologies, such as supercritical fluid extraction, microwave-assisted extraction (MAE), pressurized solvent extraction (PSE) and ultrasound-assisted extraction (UAE) are fast and efficient extraction technologies that have been used in the last decades by the food processing industries and researchers with the purpose of extracting more efficiently major and minor compounds present in natural matrices, saving energy and reagents, avoiding losses and optimizing the extracting yields (Gil-Ramírez et al, 2013;Heleno et al, 2016;Villares et al, 2014).…”

Optimization of Ultrasound-Assisted Extraction of Flavonoids from Cryptotaenia japonica Hassk. and Evaluation of Antioxidant Activity

“…Some studies have reported on the compositions and antioxidant activity of C. japonica (Cheng, Lin, Yen, & Yu, 2010;Cheng Lin, Yu, & Peng, 2008;Okude & Hayashi, 1970;Yao, Sang, & Zhou, 2010;Yao & Ren, 2011), but few studies refer to the extraction of flavonoids (Li, Zhu, & Deng, 2006). Ultrasound-assisted extraction is the new technology that has become widely applied in the extraction of a variety of bioactive ingredient (Kiani, Sun, Zhang, Al-Rubeai, & Naciri, 2013;Şahin & Şamlı, 2013;Wang et al, 2013). It has the notable advantages for decreasing the consumption of solvent and extraction time, increasing yield and ease of use (Bimakr et al, 2011;Grigonis, Venskutonis, Sivik, Sandahl, & Eskilsson, 2005) comparing with other extraction techniques such as heating, boiling, refluxing and soxhlet extraction.…”
