Optimization of Total Phenolic from <i>Cleistocalyx nervosum</i> by Microwave-Assisted Extraction

Abstract

Abstract:The objective of this research was to extract phenolic compounds from Makiang (Cleistocalyx nervosum) seeds waste obtained from the elaboration of makiang beverages using the microwave assisted extraction method. The optimal conditions of microwave assisted extraction of total phenolics from makiang seeds were determined using response surface method. The variables of microwave power, extraction time and ethanol proportion on effect of total phenolic were designed the experiment by Box Behnken design. The estimation of the mathematical model indicated that the second-order polynomial model was appropriate to determine optimal conditions of microwave assisted extraction of total phenolics from makiang seeds. The highest yield of total phenolic from makiang seed and antioxidant activity were obtained when the extraction process was set at a microwave power, 450 W, an extraction time of 213 second and an ethanol proportion of 51%(v/v). Under these optimal conditions, the predicted and experimental values of total phenolic from makiang seeds were the 75.659 mgGAE/gDW and 75.132±0.576 mgGAE/gDW, respectively. The research showed that total phenolics from makiang seeds by microwave assisted extraction have the high efficiency in terms of high yield and antioxidant activity within short time extraction which can apply to use in cosmetic product, health food and pharmaceutical industry.

Cleistocalyx nervosum var. paniala Berry Seed Protects against TNF-α-Stimulated Neuroinflammation by Inducing HO-1 and Suppressing NF-κB Mechanism in BV-2 Microglial Cells

“…Several biological activities of these berry fruits have been reported, including antiaging and neuroprotective properties, anticarcinogenicity, and immunomodulation [ 37 ]. Interestingly, a part of the seed, which is an organic waste, showed high levels of polyphenols and flavonoids [ 38 ]. However, the antineuroinflammatory studies focusing on the agricultural waste part of the seed are still limited.…”

Optimization and production of protein hydrolysate containing antioxidant activity from tuna cooking juice concentrate by response surface methodology

“…The correlation coefficient (R 2 ) of 0.9056 indicated that the statistical model was adequate and could represent the relationships between the Alcalase concentration (X 1 ) and hydrolysis time (X 2 ) on the DPPH radical scavenging activity (Y) of TCH. According to Narkprasom et al (2015), R 2 should be close to 1.0, but a value greater than 0.8 is acceptable. The coefficient of variation (CV) was used to describe the dispersion of the data and to represent the precision and reliability of the results.…”

Progress in the Valorization of Fruit and Vegetable Wastes: Active Packaging, Biocomposites, By-Products, and Innovative Technologies Used for Bioactive Compound Extraction

“…It is mainly used for extraction because it reduces solvent usage, energy consumption, extraction times, heating rates and increases extraction efficiency and selectivity, resulting in quality target products [ 148 ]. Many studies were conducted using MAE methods on FVW and FVB, including longan seed [ 149 ], tomato peel waste [ 150 ], apple pomace [ 151 ], banana peel [ 152 ], pitaya fruit peel [ 130 , 153 ], passion fruit peel [ 130 ], lemon peel, mandarin peel, and kiwi peel [ 154 ]; thus, MAE is mostly used to extract pectin from fruit waste. This approach has been used to extract high-quality pectin with biomasses such as mango peels [ 155 ], citrus mandarin peels [ 156 ], fig skin [ 157 ], orange peel, apple pomace, mango peel, carrot pulp [ 158 ], pumpkin biomass [ 148 ], and banana peels [ 159 ].…”
