Optimization ultrasound‐assisted extraction of anthocyanins from cranberry using response surface methodology coupled with genetic algorithm and identification anthocyanins with HPLC‐MS ²

Abstract

Cranberries (Oxycoccos) are mainly grown in the cold northern hemisphere (Massachusetts, Wisconsin, and Maine in the north of the United States). In addition, cranberries are also planted in the greater Khinganling region of China. Cranberry cultivation is deeply favored owing to its high nutritional value, unique aroma, and attractive red pigment (Sette et al., 2017). Cranberry, as a good source of bioactive compounds, includes anthocyanins, flavanols, various vitamins, superoxide dismutase, and phenolic acids .Anthocyanins, as one of the most essential active components in cranberry, are water-soluble natural pigments with high benefits for human health such as free radical scavenging (Jiao et al., 2018), antibacterial (Pertuzatti et al., 2016, inhibition cancer cell increment (Yun

Effects of process parameters on the extraction of total anthocyanins from purple sweet potatoes by ultrasound with wide frequency and its kinetics study

“…Nonetheless, the main drawbacks of those extraction processes are of large amount of solvents, longer time of treatment, higher consumption of energy, and lower extraction efficiency (Tiwari, 2015). As a consequence, in order to overcome these shortcomings associated with conventional extraction methods, various new techniques, such as ultrasound‐assisted extraction (Dranca & Oroian, 2019; Xue, Tan, Li, Cai, & Tang, 2021), microwave‐assisted extraction (González de Peredo et al, 2018), supercritical carbon dioxide extraction (Paes et al, 2014), and other novel extraction approaches (Budiene et al, 2021; Rakshit & Srivastav, 2021; Tzanova et al, 2020; Xue, Tan, Li, Tang, & Cai, 2021), have been developed for the extraction of anthocyanins from various plant materials.…”

Tea polyphenols alleviate hydrogen peroxide‑induced oxidative stress damage through the Mst/Nrf2 axis and the Keap1/Nrf2/HO‑1 pathway in murine RAW264.7 cells

“…Accumulating studies indicate that plant bioactive polyphenols exhibit higher antioxidant activity and lower toxicity than synthetic compounds (29)(30)(31). Research in our laboratory (Tsinghua University; Beijing) has focused on the bioactive effects of natural low molecular weight polyphenols, including lychee, tea, blueberry and other polyphenols derived from edible plants (32)(33)(34). As recognized natural antioxidants, TPs and their main four substances have been used in the prevention and treatment of clinical diseases involving oxidative damage.…”

Commercial pectin production from dried florida orange peel: Effect of process conditions on pectin structure and function

“…The limited amount of dried peel prevented a complete analysis by Response Surface Methodology using a Box–Behnken design (Xue et al, 2021). However, we were able to use the Historical Data function of Design Expert (ver.…”
