背景：青钱柳Cylocarya paliurus(BATAL.)伊尔金斯卡亚是中国家喻户晓的食药两用植物，俗称“甜茶树”。据报道，它在降低血糖、血脂和血压方面具有广泛的治疗和营养价值。然而，每年的青花鱼产量有很大一部分被浪费了。最近的报道表明，多糖是青蟹观察到的生物活性的主要活性成分。结果：微波辅助提取青冈多糖的最佳条件为：微波辐射时间20.8min，提取温度100.9℃，料水比22.1：1，此时多糖得率为5.04+/-0.09%。与常规热回流提取和超声辅助提取相比较，青钱柳多糖的MAE较高。结论：MAE法是一种较好的提取青钱柳多糖的方法。伊尔金斯卡亚。(C)2010年化学工业学会
BACKGROUND: Cyclocarya paliurus (Batal.) Iljinskaja is a well-known edible and medicinal plant in China and is commonly called the 'sweet tea tree'. It has been reported to have a broad range of therapeutic and nutritional values in lowering blood sugar, blood lipids and blood pressure. However, much of the annual C. paliurus production is wasted. Recent reports have suggested that polysaccharides are the main active ingredients responsible for the observed bioactivities of C. paliurus. In this study, response surface methodology was used to determine the optimal conditions for microwave-assisted extraction (MAE) of polysaccharides from C. paliurus.RESULTS: The optimal conditions for MAE of polysaccharides were a duration of microwave radiation of 20.8 min, a temperature of 100.9 degrees C and a water/material ratio of 22.1 : 1. Under these conditions the yield of polysaccharides was up to 5.04 +/- 0.09%. Compared with conventional heat reflux extraction and ultrasound-assisted extraction, MAE of polysaccharides from C. paliurus (Batal.) Iljinskaja saved a lot of time and gave the highest yield.CONCLUSION: The present study suggests that MAE is a good alternative method for the extraction of polysaccharides from C. paliurus (Batal.) Iljinskaja. (C) 2010 Society of Chemical Industry
