摘要：为了解1年生和多年生森林蔬菜的营养价值,对萹蓄、短穗铁苋菜、扫帚菜3种1年生森林蔬菜和小根蒜、水芹菜、打碗花3种多年生森林蔬菜的12种营养成分进行了分析。结果表明:1年生森林蔬菜的蛋白质、脂肪、总糖、β-胡萝卜素、维生素B1、B2,维生素C和P、K平均含量均高于多年生森林蔬菜,其烟酸、Ca、Fe等元素的平均含量低于多年生蔬菜。其中短穗铁苋菜为富含蛋白质、维生素C的森林蔬菜,其含量分别为6.135%、2.661 4 mg/g;扫帚菜为富含K的森林蔬菜,其含量高达6.847 5 mg/g,打碗花为富含Ca的森林蔬菜,其含量高达4.186 7 mg/g,从分析结果来看,1年生森林蔬菜的主要营养成分含量一般高于多年生森林蔬菜。
In order to learn nutrient value of annual and perennial forest vegetables,12 kinds of nutrient components were analyzed,in the annual forest vegetables,Polygonum aviculare,Kummerowia striata,Kochia scoparia,and the perennial forest vegetables,Allium macrostemon,Oenanthe javanica,Calystegia hederacea.The results show that average contents of crude protein,lipid,total sugar,β-carotene,vitamin B1,vitamin B2,vitamin C,vitamin P and vitamin K in the annual forest vegetables are higer than those in the perennial forest vegetables,but average contents of niacin,Ca and Fe in the annual forest vegetables are lower than those in the perennial forest vegetables.In addtion,K.striata contains the higest contents of crude protein,vitamin C,which reach 6.135%,2.661 4 mg/g,respectively.K.scoparia contains the higest contents of K,which reach 6.847 5 mg/g.C.hederacea contains the higest contents of Ca,which reach 4.186 7 mg/g.Based on the analysis results,contents of main nutrition components in the annual forest vegetables are generally higher than those in the perennial forest vegetables.
