摘  要:通过对西藏不同产地蕨麻样品性状、营养成分、活性成分、矿物质元素及氨基酸组分进行系统分析,旨在揭示蕨麻区域性特征和品质差异。结果表明:不同产地蕨麻在形态、表皮颜色和内部结构上存在显著差异,其中昌都市边坝县普玉二村、丁青县觉恩乡卡龙村等地蕨麻多为圆形或近圆形。营养成分分析显示,山南市错那县杰巴村蕨麻粗脂肪含量最高,而日喀则市聂拉木县乃龙乡乃龙村最低;拉萨市当雄县公塘乡拉根村朗木错蕨麻总淀粉含量最高,昌都市察雅县吉孜村蕨麻最低。在矿物质元素分析中,所有样品均未检出铍、砷、镉、锑、铊和铅元素,总矿物质元素含量最高的是昌都市边坝县普玉二村蕨麻,最低的是拉萨市尼木县卡如乡东郎二村蕨麻。氨基酸组分分析结果显示:昌都市边坝县普玉二村蕨麻氨基酸含量最高,日喀则市聂拉木县乃龙乡乃龙村蕨麻最低;在总必需氨基酸含量方面,昌都市察雅县达如村蕨麻最高,为山南市错那县杰巴村的5倍。This study aimed to reveal the regional characteristics and quality differences of fern by systematically analyzing the traits,nutrients,active ingredients,mineral elements and amino acid fractions of fern samples from different origins in Xizang.The results showed that there were significant differences in the morphology,epidermal color and internal structure of ferns from different origins,among which the ferns from Puyu Second Village,Palbar County,Chamdo City,and Karong Village,Joune Township,Tenchen County,were mostly round or nearly round in shape.Nutritional composition analysis showed that the crude fat content of ferns from Jieba Village,Tsona County,Lhoka City was the highest,while that of ferns from Nailong Village,Nailong Township,Nyalam County,Shigatse City was the lowest.The highest total starch content was found in ferns from Langmuzhuo,Lagan Village,Gongtang Township,Damshung County,Lhasa City,while the lowest was found in ferns from Jizi Village,Dayak County,Chamdo City.In the analysis of mineral elements,beryllium,arsenic,cadmium,antimony,thallium and lead elements were not detected in all the samples,and the highest content of total mineral elements was found in the ferns from Puyu Second Village,Palbar County,Chamdo City,and the lowest was found in the ferns from Donglang Second Village,Karu Township,Nyemo County,Lhasa City.The results of amino acid fraction analysis showed that the highest amino acid content was found in ferns from Puyu Second Village,Palbar County,Chamdo City,and the lowest was found in ferns from Nailong Village,Nyalong Township,Nyalam County,Shigatse City.For the content of total essential amino acids,it was highest in ferns from Daru Village.
