摘要
本研究以10种不同产地的商品山楂干[包括7种普通山楂(商品名"北山楂")、2种台湾林檎(商品名"广山楂")和1种野山楂(商品名"南山楂")]为研究对象,测定其主要营养成分和生化指标,并在此基础上对山楂进行品质差异分析和主成分分析.结果表明:在3类商品山楂干中,北山楂的可滴定酸含量最高,广山楂的糖酸比最高,而可溶性膳食纤维、α-生育酚和β-胡萝卜素含量排序均为北山楂>南山楂>广山楂.主成分分析结果表明,湖北黄冈的'野山楂'和天津蓟州的'铁山楂'在主要活性成分(总酚、总黄酮、总原花青素、总膳食纤维)含量方面整体表现较优;山东临沂的'大金星'和河南新乡的'豫北红'等北山楂在可滴定酸、可溶性膳食纤维和可溶性糖含量方面相较于南山楂和广山楂综合表现更优.本研究系统梳理了我国不同产区主要种类商品山楂干的品质差异,可为我国山楂资源的多元化开发利用提供数据支撑.
Abstract
Taking ten kinds of commercial dried hawthorn fruits[seven kinds of Crataegus pinnatifida Bge.or C.pinnatifida Bge.var.major N.E.Br.(with the trade name"Beishanzha"),two kinds of Malus doumeri(Bois)Chev.(with the trade name"Guangshanzha")and one kind of C.cuneata Sieb.et Zucc.(with the trade name"Nanshanzha")]from different producing areas of China as research materials,the contents of main nutrients and biochemical indexes were determined,and the quality difference analysis and principal component analysis were carried out.The results showed that among the three types of commercial dried hawthorn fruits,Beishanzha had the highest titratable acid content,while Guangshanzha had the highest ratio of soluble sugar to titratable acid.The contents of soluble dietary fiber,α-tocopherol and β-carotene decreased in the order of Beishanzha,Nanshanzha and Guangshanzha.The results of principal component analysis indicated that'Yeshanzha'from Huanggang of Hubei Province and'Tieshanzha'from Jizhou of Tianjin City showed the best overall performance in the contents of main active components(total phenolics,total flavonoids,total procyanidins and total dietary fiber);Beishanzha,especially'Dajinxing'from Linyi of Shandong Province and'Yubeihong'from Xinxiang of Henan Province,had greater contents of titratable acid,soluble dietary fiber and soluble sugar compared with Guangshanzha and Nanshanzha.This study systematically sorted out the quality differences of commercial dried hawthorn fruits from different areas in China,and the results can provide data to support the diversified development and utilization of Chinese commercial hawthorn resources.
