Quality difference analysis of commercial dried hawthorn fruits from different producing areas
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.
