Special Issue Information

Dear Colleagues,

Green chemistry has emerged due to the importance of the use of processes that are environmentally friendly. For extracting natural products, greener and more sustainable alternatives to traditional methods have been explored over the last decade. The knowledge generated by this topic can help society change its habits and behaviors, showing us how certain products and attitudes pose more risks to nature than others. This knowledge also ties into Sustainable Development Goals 2; 11; and, more specifically, 12, which deal with sustainable production and consumption. In this sense, with the aim of providing a new and novel knowledge base via green chemistry for natural products, we would like to invite researchers to participate in this Special Issue. Therefore, this Special Issue will focus on approaches to improve and accelerate extraction efficiency and reduce solvent consumption, such as solvent-based techniques, deep euteric solvents (DES), ultrasound-assisted extraction and microwave-assisted extraction, as well as supercritical fluid extraction and pressurized solvent extraction. However, other related research is highly encouraged. Authors are cordially invited to contribute original research articles as well as review articles. All research will be published as Open Access.

It has been discovered that the peel of a pumpkin (Cucurbita maxima), regarded as a waste product of pumpkin processing, has significant amounts of carotenoids and other antioxidants. This study aims to identify the most effective extraction parameters for an ultrasonic-assisted extraction method to extract the total carotenoids (TCs) and assess the antioxidant activity (AA) of pumpkin peel. To determine the effects of the extraction time, temperature, and material-to-solvent ratio on the recovery of TCs and AA, a response surface methodology utilizing the central composite design (CCD) was used. The extraction temperature (6.25–98.75 °C), extraction duration (13.98–128.98 min), and solvent ratio (0.23–50.23 mL) were the variables studied in the coded form of the experimental plan. The carotenoid concentration varied from 0.53 to 1.06 mg/g DW, while the AA varied from 0.34 to 7.28 µM TE/g DW. The findings indicated that the optimal extraction parameters were an 80 °C temperature, a 10 mL solvent ratio, and a 100 min extraction time. The study confirmed that the optimum extraction conditions resulted in an experimental TC yield of 0.97 mg/g DW and an AA of 7.25 µM TE/g DW. Overall, it should be emphasized that the extraction process can be enhanced by setting the operating factors to maximize the model responses. Full article
