Abstract

ABSTRACT A coupled ultrasonic extraction process of curcumin from Curcuma longa L enhanced by the graphene-oxide-assisted solvent was developed. The yield was investigated in relation to extraction temperature, extraction time, ethanol volume fraction, and graphene oxide concentration. Response surface methodology was used to develop a quadratic model of the yield and extraction process. The optimum extraction parameters with the highest yield were obtained and the economic value was then assessed. Results showed that the coupling process could reduce the extraction time, extraction temperature, and ethanol volume fraction while improving the extraction yield. The optimal process parameters were 50.0°C extraction temperature, 1.5 h extraction time, 60.0% ethanol volume fraction, and 1.0 mg/g graphene oxide concentration. The highest extraction yield was 64.9 mg/g, which was better than that have been reported. It can save an estimated $1507 in production expenses for every ton of turmeric under the optimal extraction process. Moreover, the reduction in extraction temperature and ethanol volume fraction also means a safer and cleaner production environment, which highlights the greater potential application prospect of the extraction process developed in this paper.

氧化石墨烯辅助溶剂对耦合超声提取姜黄素的影响

研究了石墨烯辅助溶剂对姜黄中姜黄素的超声耦合萃取工艺。考察了提取温度、提取时间、乙醇体积分数和氧化石墨烯浓度与收率的关系。利用响应面法建立了产率和提取过程的二次模型。获得了收率最高的最佳提取工艺，并对其经济价值进行了评价。结果表明，该耦合工艺可缩短提取时间、降低提取温度、降低乙醇体积分数，提高提取率。最佳工艺参数为提取温度50.0℃，提取时间1.5 h，乙醇体积分数60.0%，氧化石墨烯浓度1.0 mg/g。最高提取率为64.9 mg/g，优于文献报道。在最佳提取工艺下，每吨姜黄可节省生产费用约1507美元。此外，降低提取温度和乙醇体积分数也意味着更安全、更清洁的生产环境，这凸显了本文开发的提取工艺更大的潜在应用前景。
