摘要:

本实验研究了南果梨红果皮中花青素提取条件对其提取量的影响。以南果梨红果皮中花青素提取量为技术指标,采用正交试验法,考察各工艺条件对提取效果的影响,确定了南果梨红果皮中花青素提取的优选条件。结论表明,0.1% HCl-甲醇溶液(pH4.0)以1:4的料液比混合后,在50℃下浸提两次,共计240min,提取量可达40mg/g,其检测数据可靠,提取方法简单合理。

Abstract:

Objective: To explore the extraction technology of anthocyanidin from red peel of Nanguo pear in Anshang city of Liaoling province. Methods: Effects of several factors, such as extraction solvent composition, extraction times, temperature, extraction time, ratio of material to extraction solvent and pH value of extraction solvent on anthocyanidin yield, and then other four key factors except extraction solvent composition and extraction times were optimized through orthogonal test. Results: The optimum extraction process of anthocyanidin is as following: extracting red peel of Nanguo pear with 0.1% HCl-methanol solution at pH 4.0 at a ratio of material to extraction solvent of 1:4 twice at 50 ℃ for 240 min, and under the above process the anthocyanidin yield reaches 40 mg/g. Conclusion: This extraction technique is simple and reasonable, and the detected data are credible.
