【摘要】 惠楼山药产自河南省虞城县惠楼村附近,是目前尚未被深入研究的地方性栽培品种.在植物学性状观察、主要营养成分分析的基础上,探讨了惠楼山药品种特征、分类归属及命名.结果表明:惠楼山药属于怀山药的一个栽培品种,其植物学性状与太谷山药比较亲近,学名可定为Dioscorea polystachyaTurcz.cv.Huilou.惠楼山药是一种品质十分优良的山药品种.口感不麻不涩、软面而香甜.与其他山药品种相比,惠楼山药的很多营养成分具有明显的比较优势,还原糖、多糖和蛋白质含量分别为15.8g/kg、55.6g/kg和108.1g/kg,氨基酸总量为97.7g/kg,其中人体必需氨基酸和鲜味氨基酸分别占总量的28.04%和36.75%,Zn、Fe、Ba、Li、Sr等微量元素含量丰富.更多还原

【Abstract】 Huilou yam(HY)grows near Huilou Village,Yucheng County,Henan Province,and is a local cultivar not being intensively studied until now.The botanical characters,classification and nominating of HY have been discussed based on field works to survey stems,leaves,flowers,fruits and tubers of HY,and the laboratory works to determine some nutrient contents of the yam.The results show that HY is an independent cultivar belonging to Rhiizma Dioscorea oppositabecause its botanical characters are similar to Taigu yam,and its botanical name could be named as Dioscorea polystachyaTurcz.cv.Huilou.HY is a very excellent yam cultivar not only because of higher edible and medicinal values,but also good tastes of soft and sweet,not hemp and astringent.Many nutritional components in HY are higher than that in most other Chinese yam varieties.Contents of reducing sugar, polysaccharide sugar and protein in HY are 15.8g/kg,55.6g/kg and 108.1g/kg,respectively.Total amino acids(TAA)in HY is 97.7g/kg,among which essential amino acids(EAA)are about 28.04%,and flavor amino acids(FAA)are about 36.75%.HY has much rich trace elements such as Zn,Fe,Ba,Li,Sr and so on.更多还原
