Abstract

Morchella esculenta L. is a rare and the most valuable edible mushrooms. The polysaccharides of M. esculenta L. boast high nutrition and health values. This paper describes microwave extraction of the polysaccharides of M. esculenta L. by ultrasonic microwave. The optimal extraction conditions, optimized by single factor experiments and response surface method, were determined as follows: the ultrasonic power is 250 W, the microwave power is 220 W, and the extraction time is 7 min with a yield of polysaccharides at 4.425%. The crude polysaccharides of M. esculenta L. at 4 mg/mL exhibited hydroxyl radical, 2-Diphenyl-1-picrylhydrazyl radical and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging rates at 76.70%, 60.73%, and 80.87%, respectively. Its Fe2+ chelating rates increased from 45.63% to 82.50%, as the polysaccharide concentration increased from 0.5 to 4.0 mg/mL.

超声-微波共提取羊肚菌深层发酵菌丝多糖及其抗氧化活性分析

羊肚菌是一种珍贵的食用菌。藤多糖具有较高的营养和保健价值。本文介绍了用超声波-微波法提取番茄多糖的方法。通过单因素实验和响应面法确定了最佳提取条件：超声功率为250W，微波功率为220W，提取时间为7min，多糖产率为4.425%，2-二苯基-1-苦基肼基和2,2'-叠氮基双（3-乙基苯并噻唑啉-6-磺酸）自由基清除率分别为76.70%、60.73%和80.87%。当多糖浓度从0.5 mg/mL增加到4.0 mg/mL时，其Fe2+螯合率从45.63%增加到82.50%。

期刊介绍： Current Topics in Nutraceutical Research is an international, interdisciplinary broad-based peer reviewed scientific journal for critical evaluation of research on chemistry, biology and therapeutic applications of nutraceuticals and functional foods. The major goal of this journal is to provide peer reviewed unbiased scientific data to the decision makers in the nutraceutical and food industry to help make informed choices about development of new products. To this end, the journal will publish two types of review articles. First, a review of preclinical research data coming largely from animal, cell culture and other experimental models. Such data will provide basis for future product development and/or human research initiatives. Second, a critical evaluation of current human experimental data to help market and deliver the product for medically proven use. This journal will also serve as a forum for nutritionists, internists, neurologists, psychiatrists, and all those interested in preventive medicine. The common denominator of all of the topic to be covered by the journal must include nutraceuticals and/functional food. The following is an example of some specific areas that may be of interest to the journal. i) Role of vitamins, minerals, antioxidants and phytonutrients on cardiovascular health, cancer, diabetes, ocular health, mental health, men’s health, women’s health, infant nutrition, ii) Role of herbals on human health, iii) Dietary supplements and sleep, iv) Components of diet that may have beneficial effect on human health, v) regulation of apoptosis and cell viability, vi) Isolation and characterization of bioactive components from functional foods, vii) Nutritional genomics, and viii) Nutritional proteomics.
